Bearing Insert in stainless steel locking mechanisms. Eccentric Locking Collar

The eccentric locking collars are designed for use in applications where the shafts rotate in a single direction.
They incorporate a matching eccentricity between the inner ring and locking collar. 
The radiuses area in both the collar and inner ring where the eccentricity begins is instrumental in preventing cracks in this high stress area.
Matching angles between the inner ring and locking collar provide optimal contact and security.
The locking collars come standard with AISI 304 set screws.

Set Screw Locking

This incorporates two AISI 304 set screws spaced 62 degrees apart in the inner ring extension.
The areas around the set screws are high frequency annealed to allow the use of larger diameter set screws further increasing their effectiveness.
The addition of a nylon patch to the set screws prevents their backing out under high vibration situations.
