Rollers used in the past have usually been cushioned by the attachment system. The present cushioned roller includes the cushioned member being an integral part of the roller. For example, the unique roller includes a pair of individual shell portions positioned at the ends of a shaft. The shaft and a collar which is mounted to a chassis includes a cushioning member positioned therebetween the shaft and the collar. The pair of individual shell portions are separately rotatable about the shaft and the rollers are isolated from the chassis and the rollers can osculate about the chassis. Thus, the roller is free to isolate about the chassis and each of the pair of individual shell portions are in contact with each of the inner portion and the outer portion of the inner surface of the belts. Furthermore, impact loads are absorbed by the cushioning member and increase the longevity of the roller and provide a better ride for the operator. |
