A bearing assembly for a Hookes universal joint including a bearing bush (11) with an external surface (16) for reception in a bore (12) in joint yoke (6), and a support ring (18) screw-threadedly engaged on the external surface of the bush at its ends nearest the axis of rotation of the joint yoke, for adjustment of the position of the bush in the yoke. For locking the support ring (18) in its adjusted position a locking member (23) is provided, with surfaces (24, 25) of different radii of curvature and/or offset centers of curvature so that the locking membrer can become jammed between facing cylindrical surfaces (20, 21) of the bearing bush and support ring. A spring (28, 29) is provided to bias the locking member to its jammed position, and a releasing pin (31) to release it to enable adjustment of the support ring.
