Eccentric Collars

Motion offers a variety of eccentric collars from leading brands like NTN, Timken, and Dodge. Eccentric collars are self-locking collars that lock bearings onto shafts and reduce bearing wear. They are used with bearings that rotate in one direction only and should be tightened in the same direction as shaft rotation during installation. The collar engages the inner ring of the bearing and grips the shaft tightly, never loosening during operation. An integrated set screw provides further locking action without any additional adjustments. Standard eccentric collars eliminate the need for lock nuts, sleeves, adapters, shoulders, and washers.
