Abstract
A tripot joint includes a tripot housing having a plurality of longitudinally extending ball channels for receiving a corresponding plurality of trunnions projecting from a shaft. Each trunnion is fitted with a ball module formed as a separate sub-assembly from the trunnions. Each ball module includes a roller ball having a bore in which a plurality of needle bearings is disposed. A bearing cage is received with a snap-fit connection within the bore to retain the needle bearing within the roller ball independently of the trunnions.
