Radial bearingplacement reduceswear and tracking. 

Designed to rotate on the post, as well as maintain its 
vertical motion, LEMPCO ROTAINERS. were developed 
to greatly reduce the amount of tracking. The disengagement 
of the guide post from the bushing by 1/4” at the top of the 
stroke will allow the ROTAINER. to rotate 360° on the guide 
post. The ROTAINER., while still designed to track, (assuring 
a measurable amount of preload) will enable stampers to 
achieve high press production by reducing expensive 
replacement costs.

Mounting diameters of the LEMPCO 
Shoulder Guide Posts are a minimum of .008” 
over the sizes of Press Fit Steel Sleeve Bushings 
and .008” over the Demountable Steel Bushings 
to allow grind stock for precision fitting in new 
set construction and to allow reboring as 
necessary in replacing posts and bushings in 
used sets. These posts also may be used with 
Press Fit Sleeve Bushings and Demountable 
Bushings providing the through bore size 
accords with mounting diameters. 

The Shoulder Guide Posts are manufactured 
from 52100 tool steel and precision ground. 
See pages 13–15 for mounting instructions. 

NOTE:

The 953 Series product line is not stocked, but is 
available as a special order. 

BaLL BeaRING eNGINeeRING DaTa 
Boring procedures and dimensions 
BaLL BeaRING eNGINeeRING DaTa 
Boring procedures and dimensions 
Holes for LEMPCO Ball Bearing Guide 
Posts and Bushings should be jig bored for best 
results. The punch holder and die holder should 
be clamped together and bored in one setup 
in order to maintain dead center alignment 
between the upper and lower bores. If it is not 
possible to bore in this manner, a tolerance of 
±.0005” between centers (see illustration) must 
be held. Bores should be smooth and free from 
tool marks to provide proper bearing area for 
the guide post and bushing. 

Die holder bores must be perpendicular to 
the surface of the die holder which will back 
up the die. The bottom surface of the die holder 
must be parallel to the die backup surface. The 
punch holder bores also must be perpendicular 
to the surface which will back up the punches, 
and the top surface parallel to the punch backup 
surface. 

Break the corners of the bored holes to a 
generous chamfer. On sets with a symmetrical 
profile one pin and bushing should be offset 
to prevent accidental reversing of the punch 
holder during assembly. 

All of the LEMPCO Ball Bearing Guide 
Posts, Bushings Retainers and Rotainers. are 
completely interchangeable without the need 
for select fitting, and if mounted in accordance 
with boring and assembly instructions given 
on this and the following page do not require 
any grinding, honing, lapping, or any other 
modifications of any kind. Please note the 
dimensions given in the following table. Our 
experience over many years proves that these 
are optimum dimensions. Variations must be 
avoided.

BaLL BeaRING eNGINeeRING DaTa 
installation and assemBly instructions 
In order to maintain the die and 
punch alignment, it is essential that 
the guide posts and bushings be 
at absolute right angles with the 
punch and die backup surfaces. 

Figure 1 represents a typical 
guide post and ROTAINER.. Please 
note that the end of the guide post 
with the small radius is press fit 
into the punch shoe, and that the 
ROTAINER. is assembled with the 
ROTAINER. slide assembly toward 
the same end of the guide post. 

NOTE: LEMPCO Demountable 
Bushings and Flanged Demountable 
Guide Posts are tap fitted. Bores 
should be to specifications, and 
both bushings and guide posts 
should be seated flush to ground 
surface of support shoe and held 
securely by clamps and cap screws. 
These bushings and guide posts 
are removable; on installation the 
die will register accurately. 

Check the squareness of the 
guide post or bushing with a 
precision square. Tap the sides 
slightly with a soft hammer until 
the guide post or bushing is 
perpendicular. 

Press fit about 1/4” (6.35mm) 
and check with the precision 
square again, tapping the sides 
with a soft hammer as necessary, 
to ensure squareness. A bronze, 
babbitt or fiber hammer is recommended. 

NOTE: With Demountable Boss 
Bushings, be sure to press against 
the hardened liner and not against 
the casting. 

Press fit by small increments – not 
over 1/2” (12.70mm) each – checking 
with the precision square after each 
press. Do not allow guide post or 
bushing to protrude through the 
lower side of the plate. It is advisable 
to place a 1/64” (.3968mm) shim 
under the guide post or bushing as 
a stop. 

For Demountable Boss Bushings 
and Demountable Bushings, after 
the bushing is tap fit to the shoulder, 
the shoe may be drilled with the 
bushing in place. Tighten screws 
gradually, moving from one to 
another until all are tight. 

After complete assembly of 
the bushings, check the ID top and 
bottom for taper. Should taper be 
found, hone the ID until original 
size is obtained. 

NOTE: This should not be necessary 
if boring instructions were strictly 
adhered to. 

Assemble ROTAINER. to guide 
post (Figure 1) by screwing the set 
screw in until flush with the special 
ROTAINER. slide. Vertical and the 
rotational movement should now 
be tested to insure freedom of 
movement. After testing is completed, 
stake set screw. Lubricate only with 
a light spindle oil. 

NOTE: The only tool necessary 
to assemble the ROTAINER. is a 
screw driver. 

Assemble the punch and die 
holder. Be sure to allow the 
ROTAINERS. to hang free (see 
Figure 2) supported by the special 
ROTAINER. slide when assembling 
the die set. Work the punch holder 
up and down a few times to assure 
there is no binding.

B. Lay out die as in Figure 2 (Maximum Shut Height). 
C. Maximum Open Height (Maximum Shut Height plus Stroke) as in Figure 3 shows minimum 
guide post engagement in bushing that is required. If this is at least 3/4” then conditions are 
ideal. However, if this dimension is less than 3/4” then Figure 4 should be considered. Actual 
work is done for only a fraction of the total stroke on most dies and if conditions shown in 
Figure 4 are satisfied in conjunction with Figure 1 and Figure 2, then full length of stroke 
and maximum open height can be disregarded. 
ALSO NOTE, HOWEVER, THAT LONGER THAN NORMAL STROKES MAY BE UTILIZED BY 
DISENGAGING GUIDE POST AND, IF ABSOLUTELY NECESSARY, THE ROTAINER. FROM 
THE BUSHING ON THE UPWARD TRAVEL PROVIDED: 

1 – THE OPERATION IS VERTICAL 

2 – THE OPERATION IS NOT FASTER THAN 150 STROKES PER MINUTE, AND 

3 – THE INSIDE DIAMETER OF THE BUSHING IS BELL MOUTHED MINIMUM 1/4”. 

ON INCLINED OPERATIONS, OR AT SPEEDS IN EXCESS OF 150 STROKES PER MINUTE, THE 
GUIDE POST MUST ENGAGE THE BUSHING AT ALL TIMES AT LEAST 3/4” (THE ROTAINER. 
MUST BE ENGAGED BY THE GUIDE POST AND BUSHINGS AT ALL TIMES).

Component maintenance is a serious business... 

BALL-SCRUBB. removes heavy soils, dirt or grease from 
ball-bearing guide pin assemblies. 

Just spray it on...wait 3 minutes... and spray again. Then 
blow off excess with compressed air. 

BALL-SCRUBB. is an industrial strength cleaner with rust 
inhibitors, specially formulated to clean debris and grease 
from all types of ball-bearing assemblies. 

BALL-LUBE., when applied after BALL-SCRUBB., locks out 
wear by chemically bonding to precision surfaces. It provides 
a tough, long-lasting shield that protects against oxidation 
and rust. 

BALL-LUBE. lubricates assemblies and gives them longtime 
protection against wear, oxidation and heat. 

Spray liberally on ball-bearing assemblies. 

Always use Ball-Lube. 
and Ball-Scrubb. to keep 
ball-bearing components 
clean and running smooth.

Fatigue failures begin with a small crack in the material. The crack will develop 
at a point of discontinuity in the material, such as a change in cross section, 
a keyway, or a hole. Once a crack has developed, the stress-concentration 
effect becomes greater and the crack progresses more rapidly. As the stressed 
area decreases in size, the stress increases in magnitude until, finally, the 
remaining area fails suddenly. 

The original LEMPCO ball staking design consisted of small rectangular 
indentations opposing each other at 180° degrees around the ball (two-point 
staking); see Figure 1. This staking design consists of no/minimal radii, two 
full corners, and numerous material discontinuities, all allowing opportunities for 
crack propagation. 

SOLUTION 

We developed an improved ball staking method that consists of a complete 
circular indentation around the entire ball (orbital staking); see Figure 2. This 
design utilizes a uniform circular metal forming technique, with no sharp 
discontinuities in the material. The new method is intended to improve 
performance in regards to operational life cycle. 

CONCLUSION 

After an independent third party* ran a Finite Element Analysis, the following 
can be concluded: 

. 
The peak stress and stress levels in general are much higher for the 
two-point stake than for the orbital stake. Figure 3 shows stress 
contours for the two-point stake, Figure 4 shows stress contours for 
the orbital stake. 
. 
Due to the smaller volume of material in the two-point stake, high 
stresses exist in a significant portion of the indented material. 
. 
The differences in stress levels and distribution imply that the fatigue 
life for the two-point stake will be much less than for the orbital stake, 
and with the lower stresses the orbital stake should improve the 
fatigue life. 
. 
The differences in stress levels of the orbital stake design also imply 
that press speed can be increased with the orbital stake compared 
to the two-point stake.

These unique hard coated aluminum bushings have the surface 
hardness of case hardened steel. An electrochemical process is used 
to increase the corrosion resistance of the bushings. As a result of 
this Hard Anodized process, they are also non-conductive, so they may 
be used for electrical discharge machining. They have a hard surface 
that is highly resistant to wear and not subject to magnetization. 
These bushings are for clean room and EDM applications and 
should not be used in any stamping operation wherein a lot of 
contaminants are generated. 

Lempcoloy. bushings do not require lubrication and therefore 
are not provided with the conventional figure-eight oil grooves 
and fittings. While these bushings do not require lubrication, we 
recommend you apply a light mist of spindle oil prior to assembly 
and spray lightly prior to each press run. 

Lempcoloy. bushings are designed to be installed by tap fitting 
to seat flush with the ground surface of the punch holder. They are 
assembled with toe clamps and screws. These bushings must not 
be pressed in or honed. These Lempcoloy. bushings will work well 
when used with Lamina plain bearing guide posts.

Radial bearingplacement reduceswear and tracking. 

Designed to rotate on the post, as well as maintain its 
vertical motion, LEMPCO ROTAINERS. were developed 
to greatly reduce the amount of tracking. The disengagement 
of the guide post from the bushing by 6.35mm at the top of 
the stroke will allow the ROTAINER. to rotate 360° on the 
guide post. The ROTAINER., while still designed to track, 
(assuring a measurable amount of preload) will enable 
stampers to achieve high press production by reducing 
expensive replacement costs.

Boring procedures and dimensions 
Holes for LEMPCO Ball Bearing Guide 
Posts and Bushings should be jig bored for best 
results. The punch holder and die holder should 
be clamped together and bored in one setup in 
order to maintain dead center alignment between 
the upper and lower bores. If it is not possible to 
bore in this manner, a tolerance of ±.0127mm 
between centers (see illustration) must be held. 
Bores should be smooth and free from tool marks 
to provide proper bearing area for the guide post 
and bushing. 

Die holder bores must be perpendicular to the 
surface of the die holder which will back up the 
die. The bottom surface of the die holder must 
be parallel to the die backup surface. The punch 
holder bores also must be perpendicular to the 
surface which will back up the punches, and the 
top surface parallel to the punch backup surface. 

Break the corners of the bored holes to a 
generous chamfer. On sets with a symmetrical 
profile one pin and bushing should be offset to 
prevent accidental reversing of the punch holder 
during assembly. 

All of the LEMPCO Ball Bearing Guide Posts, 
Bushings, Retainers and Rotainers. are completely 
interchangeable without the need for select fitting, 
and if mounted in accordance with boring and 
assembly instructions given on this and on page 14 
do not require any grinding, honing, lapping, or 
any other modifications of any kind. Please note 
the dimensions given in the following table. Our 
experience over many years proves that these are 
optimum dimensions. Variations must be avoided.

Our spring retainers hold individual springs firmly 
in position while the die is being assembled or 
disassembled. Pre-loading the spring is easy since 
the springs can be set individually, which avoids 
working against the combined force of the springs.

Available for springs 1 1/4” (32mm), 1 1/2” (38mm) 
and 2” (50mm) diameters and any free length 
where clearance permits.

accu-bendtm rotary benders! 

Accu-BendTM units include a tool steel Rocker set into a steel Saddle with a graphite plugged 
Aluminum-Bronze liner. Available in standard inch and metric sizes with Rocker diameters of 
20mm–115mm (0.75” – 4.5”) and lengths of 50mm–900mm (2.0” – 35.0”), these units transfer the 
vertical motion of the press into a smooth one-motion rotation. The smooth rotation provides 
a rotary bend process which requires less tonnage and less strain on the material. The Accu-
BendTM Rotary Bender can also include optional pre-configured mounting hole patterns. 

The saddle liner is a bronze alloy chosen for the ability to hold up to a bearing load with little to 
no wear while the graphite plugs are included in the bronze liner to provide lubrication. Both 
Rockers and Saddles are machined for precision and interchangeability. Compact benders fit in 
tight places and are ideal for bending small tabs within a larger part. Specials can be manufactured 
for your custom needs as well when an off-the-shelf product doesn’t work for your application.

urethane 

The Formathane. product line of urethane bars, rods, sheets, 
springs, film and strippers stands alone when compared to 
other urethane products offered in the market. Formathane. 
is formulated with the metalforming and fabricating user in 
mind to withstand the rigors of these difficult environments. 
Every day customers are putting it to the test and are finding 
double and triple life expectancies are more the norm than 
the exception with Formathane.. The higher than average 
performance is due to using premium grade urethane compounds, 
computer controlled production methods and stringent quality 
standards. Often used for springs, strippers, wear pads, vibration 
dampening, forming and part protection, Formathane. is 
offered in four durometers from 70 – 95A. 

As a manufacturer of high quality springs in all standard ISO 
sizes, we also have available a line of true metric springs, in 
all the standard JIS (Japanese Industrial Standards) sizes and 
color load ratings. This extension of the spring line gives more 
options to customers with exacting requirements, making 
them available from the same reliable source as the inch springs. 
Manufactured in an optimal rectangular design and from a 
high strength chromium alloy material, these springs provide 
stability between load deflection and cycle life. The JIS product 
offering includes over 1,000 part numbers divided into five 
duty groups (colors), with fourteen diameters available per 
diameter and free lengths from 20mm to 300mm. 

We offer a comprehensive range of standard punches and die 
buttons in the basic, ball lock and variable precision series. Each 
component is made of quality heat treated tool steel which 
meets or exceeds ANSI standards. They are available in A2 high 
performance tool steel for toughness and economy, and M2, 
high speed steel, triple-tempered for long runs where abrasion 
resistance is required. Also available as a special option is PM4 
which offers improved wear and impact characteristics ideal 
for optimum performance at high operating speeds.
