Axial-Thrust Assembly removes shrink-fit and frozen parts.
Solution Series Assembly consists of two steel, 2-piece collars; one which is free to slide on shaft and push against component to be moved, and another which clamps securely to shaft. It provides Ã-½ in. range of motion. Available in 8 sizes from Ã-¾ to 2Ã-½ in. I.D., assembly can be infinitely repositioned along shaft and offers from 5,000 to 8,000 lb thrust, depending upon size.

Rotary Encoder Collar can be used to sense shaft speeds.
Aluminum clamp-type collars can be configured with metallic targets to permit shaft speed sensing. Metallic targets can be read by customer-supplier variable reluctance sensors. Collars are unaffected by oils and coolants, and smooth bore will not damage shafts. They are available in one- and two-piece clamp-type designs with bore sizes from 1/2 in. and ODs up to 12 in. Applications include...

End Stops reduce noise and excessive wear.
Cushioned End Stops are neoprene spacers that match ID/OD dimensions of shaft collars to reduce problems caused by metal-to-metal contact in linear stroke applications. PTFE version provides low coefficient of friction in rotary applications, and help prevent galling from stainless steel contacting stainless steel. End stops come in sizes from 1/2 ID x 1-1/8 in. OD up to 2 ID x 3 in. OD. Neoprene...
