A fixed type constant velocity joint includes: an outer race having an inner spherical surface, and a plurality of guide grooves formed in the inner spherical surface of the outer race; an inner race having an outer spherical surface, and a plurality of guide grooves formed in the outer spherical surface of the inner race, said guide grooves of the outer race and said guide grooves of the inner race together forming a plurality of ball guide tracks; a plurality of balls disposed in the ball guide tracks; and a cage having a plurality of windows for retaining the balls therein. The ball guide tracks include first tracks and second tracks with different groove configurations and having dual, multiple, or differentiated center offsets with smaller offsets applied to the tracks having relatively large ball movements and larger offsets applied to the tracks having relatively small ball movements as the joint is articulated for assembling.
