A thrust ball bearing is a kind of separated bearing. The bearing ring “seat ring” can be separated from the assembly of the cage steel ball. The shaft ring is a ring matched with the shaft, the seat ring is a ring matched with the bearing seat hole, and there is a gap between the shaft and the ring. Thrust ball bearings can only extract the axial load, one-way thrust ball bearings can only bear the axial load of a room, and two-way thrust ball bearings can bear the axial load of two directions. Thrust ball bearing can not limit the longitudinal displacement of the axis, the limit speed is very low. One-way thrust ball bearings can limit the axial displacement in one direction of shaft and shell, and two-way bearings can limit the axial displacement in two directions. Mainly used in the automobile steering mechanism, machine tool spindle.<\/p>
