Description
When you’ve got a bearing that needs to stay put on a shaft, this eccentric lock collar does the job right. It’s specifically designed for use with Timken/Fafnir insert bearings and provides a solid, secure grip that won’t slip even when things get rough. Instead of relying on set screws that can work loose or mar your shaft, this collar uses an eccentric locking design that clamps tight all the way around.
What You’re Getting
- Eccentric locking mechanism that provides 360-degree clamping force without shaft damage
- Precision machined to exact Timken specifications for proper fit and function
- Durable steel construction with protective finish to resist corrosion
- No special tools required—tightens with standard hex key
Built for Heavy-Duty Applications
This 2-7/16 inch collar is sized for larger shafts commonly found in hay equipment, grain handling systems, and heavy-duty agricultural machinery. You’ll find it used with wide inner ring insert bearings in applications like combine drives, chopper assemblies, and implement gearboxes where reliable shaft positioning is critical for smooth operation.
Made to Last
Timken builds these collars to the same standards as their bearings—designed to handle the constant vibration, dirt, and demanding conditions that come with farm work. The eccentric design distributes clamping forces evenly, which means less stress on both the collar and the shaft over time.
Installation Notes
Simply slide the collar onto the shaft, position it against the bearing’s inner ring, and tighten the hex screw. The eccentric action gradually increases the clamping force as you tighten, creating a secure hold without the shaft scoring you’d get from set screws. A small dab of anti-seize on the threads makes future removal easier.
