2. General Specifications
2-3
16. Counter Balanced Input Arms
• Input arms on equipment are counter balanced where appropriate to eliminate the weight of the
assembly from the weight selected by the user.
17. Radial Bearings
• Radial bearings are pillow block bearing with basic radial load rating of over 2000 pounds. Pillow
block bearings allow shaft to self-align as well as rotate, which results in smooth and friction free
movement.
18. Linear Bearings
• Linear bearings are packed with grease at the factory and sealed with synthetic rubber and steel
seals.
• Bearing plates are rolled from high quality bearing steel hardened to Rockwell 60C. Bearing balls
are chromed steel hardened to Rockwell 60C.
• The bearings feature ball conforming grooves, axial compliance, and self-alignment capability.
19. Shafts
• All Linear bearing machines run on Thompson 60 Case Class L shafts or equivalent.
20. Bolts
• All hardware is grade 5, grade 8, or stainless steel.
21. Upholstery
• A superior grade of Boltaflex colorguard vinyl is used on all pads and wear covers. This material
utilizes the Prefixx finish to resist wear and stains from sweat and other deteriorating factors.
• All edges are stitched to eliminate any folds in the material that would limit durability.
• Wear covers are provided on all high use areas, so that rather than replacing an entire pad, the
wear cover can be replaced at a fraction of the cost, reducing maintenance expense.
22. Foam
• Three and four pound EVA foam (deformation resistant) or equivalent shall be used on all
machines. Foam shall be glued to a support board and contour shall be shaped. Wood backing
shall be set with minimum 1/4” x 20 T-nuts
