Abstract
Abstract An assembly of a bearing unit with inner and outer members and rolling elements between them and a universal joint member, with a retaining element which has been deformed to hold the members together and removal of which to permit dismantling of the assembly leaves at least one of the members undamaged and fit for further service. Torque transmission between the members may be by way of tapered splines.
