A displacement joint includes an outer joint part having circumferentially spaced recesses to form tracks. A tripod is mounted in fixed rotative engagement to a driveshaft and includes a tripod spider which has spherical arms spaced circumferentially in symmetric disposition for engaging the recesses. Roller bearing assemblies are fitted in the outer joint part to support the tripod arms, with each tripod arm guided by two roller bearing assemblies. Each roller bearing assembly has a bearing shell, which receives the tripod arm, rolling members fitted with clearance in a cage and disposed between the track of the outer joint part and a contact surface of the bearing shell. The cage is guided by shoulders of the outer joint part, which laterally bound the track, wherein the cage has opposite collars in parallel relationship to the shoulders for providing an axial stop for the rolling members and the bearing shell. |
