USE A LIGHTWEIGHT SPINDLE OIL OR AUTOMOTIVE TYPE AUTOMATIC TRANSMISSION FLUID. CAUTION: NEVER USE GREASE! 3 ROTAINERS® For Ball Bearing Applications Designed to rotate on the post, as well as maintain its vertical motion, LEMPCO’s ROTAINER® was 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.

The punch holder and dieholder 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. Dieholder bores must be perpendicular to that surface of the dieholder which will back up the die. The bottom surface of the dieholder must be parallel to the die backup surface. The same holds true for the punch holder: the bores must be perpendicular to that 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 LEMPCO Ball Bearing Guide Posts, Bushings Retainers and Rotainers are completely interchangeable without any necessity whatsoever for select fitting of any kind, 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.

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. On the bushing, however, the end with the large outside diameter radius is press fit into the die shoe. 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" 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" 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" 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 special ROTAINER® slide. Vertical and 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 punch and die holder. Be sure to allow ROTAINERS® to hang free (see FIGURE 2) supported by the special ROTAINER® slide when assembling die set. Work the punch holder up and down a few times to assure there is no binding.

Maximum Shut Height – See Figure 2, below. 2. Minimum Shut Height – See Figure 1. 3. Stroke – See Figures 2 and 3. 4. Maximum Open Height – See Figures 2 and 3. A. Lay out die as in Figure 1 (Minimum Shut Height). This determines maximum guide post length and maximum bushing height. 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). 17 LEMPCOLOY® SELF-LUBRICATING BUSHINGS Lempcoloy® is now available in standard and short shoulder demountable bushings for use in die set applications. This unique bearing material has a hardness rating of 60-70 on the Rockwell C scale, and offers exceptional wear resistance in addition to being self-lubricating. Although a light spindle oil is recommended at start-up, Lempcoloy® can be used with absolutely no lubrication in demanding applications. The medical and food processing industries have used Lempcoloy® for decades with exceptionally good results. Ten sizes of bushings are available, in both the standard and short shoulder designs, with a range of the inside diameter from .5 inches to 3 inches. The Lempcoloy® demountable bushings work well with 501 and 506 style plain bearing posts. Additionally, custom bushings may be ordered in sizes from a .5 inch to a 7 inch inside diameter with lengths up to 14 inches. 18 LEMPCOLOY® SELF-LUBRICATING BUSHINGS Shoulder -Lempcoloy® CatalogNumber Inside Dia.

These mounting diameters are a minimum of .007" over the size of Precision Press Fit Bushings and .009" over Precision Demountable Bushings so as to allow grind stock for precision fitting in the construction of new sets and to allow reboring where necessary to replace guide posts and bushings in used sets. LEMPCO Shoulder Guide Posts are precision ground. Mounting instructions on page 30 of this catalog should be strictly followed. The mounting diameter lead edge should be smoothly blended after grinding to prevent hole broaching or drift during assembly.

The punch holder and dieholder should be clamped together and bored in one set up to maintain dead center alignment between upper and lower bores. If this is not possible, a tolerance of ±.0005" between centers must be held. Bores should be smooth and free from tool marks to provide proper bearing area for the guide post or bushing. Dieholder bores must be perpendicular to that surface 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 must be perpendicular to the surface that 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 LEMPCO Plain Bearing Guide Posts and Bushings are interchangeable without select fitting, and when mounted in accordance with the instructions and bore sizes given, do not require honing for fits except in the case of press fit mounted bushings. Please note the dimensions given in the tables. Experience proves that these are optimum dimensions and variations may cause trouble.
