In a raceway-guided or flange-guided cage made of plastic for roller bearings, webs (18) between side rings (14) and (16) are specially designed to prevent foreign particles present in the lubricant from damaging contact surfaces (S) of rollers (R). For this purpose, guide surfaces (26) are provided only at edges of rollers (R). Intermediate web side surfaces (30, 32) are set back from contact surface (S) by a wider gap (G). Retaining projections (40) are also separated by a gap (G.sub.1) from contact surface (S) in the axial center, the point of greatest flexiblity for the snapping-in of the rollers.

Flange or raceway guided plastic cage for bearing assembly

A bearing unit consists of a radial bearing 1 and an axial bearing 2, the outer ring 3 of the radial bearing 1 being extended at one end in the axial direction to hold the axial bearing 2. So that the bearing unit is able to absorb large radial and axial forces and is reliably sealed off against contamination from the outside, the outer ring 3 of the radial bearing 1 consists of a solid piece of material, and the extension 3.sup.a of the outer ring 3 is provided, starting from the end surface 4, with a bore 4.sup.a to hold the axial bearing 2, this bore being sealed by a bearing housing cover 6, which rests against the end surface 2.sup.a of the axial bearing 2 and is connected to the outer ring 3.

For a bearing bushing of generally cup-like form for universal joints including a universal joint pin, a check plate disposed between the axial end face of the pin and the bottom wall of the bushing, said check plate having on the side thereof confronting the pin concentric or circumferentially distributed projections with check surfaces and in that, proceeding from the end surface facing away from the pin, it has recesses or the like, which are arranged under the projections in the axial direction.
