Tripod universal joints feature three trunnion rollers running inside a tripod housing with precision needle roller bearings on each trunnion. This design provides excellent plunging (telescopic) capability while transmitting torque, making it the standard inner joint for front-wheel drive vehicle half-shafts. The tripod design accommodates both angular misalignment and axial displacement, essential for suspension movement. Also used in industrial telescopic drive shafts requiring axial compensation.
