Abstract
A fixed constant velocity universal joint having direct spherical contact and support between inner and outer race members to prevent axial movement has inserts which can be replaced, when worn, with new inserts. The universal joint includes an inner race member having a plurality of recesses and an outer race member with a plurality of recesses, each containing one of the inserts. Bearing balls are located in grooves in the inserts which are so arranged that they require axial support in one direction only by a retainer which is fully enclosed in the universal joint and abuts the bearing balls. A seal engages the inner and outer race members on the side of the bearing balls opposite the retainer. The seal includes a base held in an annular recess in the outer race member and at least one resilient finger engaging a partially spherical surface on the inner race member.
