Setscrew locking housed units are equipped with two specially designed setscrews positioned at a 90-degree angle in an inner ring that locks onto the shaft. Advanced Shaft Guarding Technology™ is offered within this design.

This locking system is popular for providing the most security for a broad range of applications. Self-locking collars eliminate the need for locknuts, washers, shoulders, sleeves and adapters.

Frequently used in limited space and reversing applications, the concentric locking collar includes two setscrews, 120 degrees apart, that pass through drilled holes of an inner ring to lock the bearing to the shaft with minimum inner ring stress and deformation.

These housed units, specially designed for unique applications and environments, offer several expanded options.

Easy-to-install, Timken's safety end caps protect exposed rotating stub-end shafts, reducing hazards around many types of equipment.
