Abstract

This caster wheel has outer and inner portions 1 and 2 which are made of relatively hard material, such as 65 Durometer D urethane. An intermediate layer 3 is softer material, for example, 78 durometer A urethane. The wheel also includes the usual roller bearing 4. The caster wheel provides high impact resistance, easy rolling characteristics under heavy loads, and is resistant to taking a set when left standing under heavy loads.
