Thrust ball bearings with flat back face are separable and divided into single direction and double direction designs. The single direction thrust ball bearings with flat back face can only be used to carry axial load in one direction and limit the axial displacement in single direction. The double direction thrust ball bearings with flat back face can be used to carry axial load in both directions and limit the axial displacements in both directions. Neither of them can carry radial load.
LEGEND standard single direction thrust ball bearings consist of a shaft washer with groove raceway, a set of balls and cage assembly and a housing washer with groove raceway. Shaft washer is fitted onto the shaft. The standard double direction thrust ball bearings consist of two housing washers with groove raceways and shaft washer with groove raceways in each face, two sets of balls and cage assembly. This type of bearings has a pressed steel cage. But the thrust ball bearings with a solid cage made of brass or steel can also be provided.
Angular contact thrust ball bearings are mainly used to carry axial load. At the same time, it can also carry a certain radial load. So they can make up for a weakness of thrust ball bearings with flat back face which cannot carry radial load. The contact angles are 45¡ã and 60¡ã .The smaller the degree of contact angle, the heavier the capacity of radial load.
Type: single direction, double direction, angular contact, banded type
Cage: pressed cage, solid cage, nylon cage
