Abstract
A novel method, for fabricating a tolerance ring suitable for use in applications such as an actuator assembly for a disk drive, is disclosed. The tolerance ring may be fabricated by steps including stamping a sheet metal section from a strip of sheet metal that has first and second edges that are parallel to a strip axis. A leading axial edge may be rounded from an inner major face and from an outer major face. A plurality of protrusions may be formed from the first major face. The sheet metal section may be bent into a substantially cylindrical shape having a central axis that is normal to the strip axis.
