Castor wheel for travel trunk has ball bearing for steering castor with projection to reduce noise

摘要

The castor wheel for a travel trunk has a roller mounted by a pin (44) in a fork (30) rotatably mounted on a bracket (20). A ball bearing (50) between the fork and bracket has a cage with spaced openings for the bearing balls. The cage is a plate with a projection (56) which engages the bracket surface which engages the bracket surface. This reduces bearing noise as the fork pivots.
