Abstract
Abstract A protective support for a ball bearing comprises an annular resiliently pliable element which snaps into engagement with the outer bearing ring and which has at least one circular lip on its inner edge for contacting the cylindrical surface of the inner bearing ring. The annular element is provided with a central radially deformable part which accommodates thermal expansion and prevents deformation of the element.
