Tolerance ring with debris-reducing profile

摘要

A tolerance ring for applications requiring cleanliness has contacting portions having a novel profile that reduces debris generation during installation of the tolerance ring while still providing adequate stiffness after installation. The tolerance ring is suitable for cylindrical interface applications where both a reduction in debris generation and high interface stiffness are desirable, such as the interface between an actuator pivot bearing and an actuator arm in a magnetic hard disk drive.
