Concentric Locking Collar

Concentric locking collars are used where setscrew locking is preferred but inner-ring stress or distortion are of major concern. These are frequently employed when space is limited and reversing shaft rotation occurs.

These housed units are selected where setscrew locking is preferred, but inner- ring stress and/or distortion are of major concern. They are frequently used in limited-space applications and where reversing shaft rotation is encountered.

Design Attributes

Bearings are locked onto the shaft by two set screws, 120 degrees apart, tightened in the collar and passing through drilled holes in the inner ring.
