TRACK ROLLER

摘要

A track roller has a stepped diameter shaft with a pair of spaced shoulders and an outer track engaging rim with a pair of opposite end faces individually substantially alignable with the shoulders of the shaft. A rim clamping and positioning device is disposable in opposing sliding relation against the shoulders of the shaft for rotatably mounting the rim on the shaft and has a sleeve portion extending in full load bearing relation between the shoulders of the shaft. A pair of opposing clamping surfaces are each positionable in facing, tightly clamping relation against respective ones of the end faces of the rim for limiting relative axial movement between the rim and shaft.
