Abstract
Described herein is a tolerance ring for a disk drive that includes a substantially cylindrical body having outer surface. The tolerance ring can be positioned between a rotational bearing and an actuator for providing rotational movement of the actuator. The tolerance ring can also include a contact member, positioned along the outer surface, that protrudes outward from the outer surface. The contact member can be connected to the outer surface by first and second angulated arms that extend from the outer surface to the contact member at different angles relative to the outer surface.
