Durasoft rollers have "teardrop" holes to allow the roller to flex for firm but non-damaging contact.
Bearings included (held in place with snap rings). Durasoft rollers have "teardrop" holes to allow the roller to flex for firm but non-damaging contact.
Designed to be mounted onto a shaft. A hub extends past the roller and is supplied with two set screws at 90°.
A clutch bearing allows the roller to turn in only one direction. Available in left or right hand rotation (with the stud pointed upwards, a right hand rotation turns clockwise).
Associated Products
Solid rollers with smooth surface and solid body making them ideal for moving components. Nitrile, neoprene or urethane material. Widely used for material and component handling in auomated processes.
Self compensating fixed shock absorbers are consistent and reliable dampening force to linear deceleration, throughout entire impact stroke.
Features
Product Overview
Solid Rollers - have a smooth surface and a solid body
Durasoft Rollers - have a smooth contact surface with teardrop holes to allow greater roller compression under load
Finned Rollers - are grooved and provides self-cleaning as dirt, debris and liquid pass under the contact surface of the roller

With the calculations above, typical life is approximately 2500 hours.
Clutch bearings
| Bearing Type | Inside diameter (inches) | Outside diameter (inches) | Width (inches) | Load (Kg) | Speed (rpm) |
| H | .3745/.3750 | .6245/.6255 | .865/.875 | 167 146 116 85 | 33 50 100 250 |
| I | .6245/.6250 | .8745/.8755 | .990/1.000 | 277 242 192 142 | 33 50 100 250 |
With the calculations above, typical life is approximately 1,000,000 revolutions or 500 hours. The bearings are shielded and pre-lubricated for life with grease.
A Clutch Roller can only be used in one direction, as shown. See data table for clutch direction of particular part.
