The thrust ball bearing is a separate bearing, shaft ring, seat ring can be separated from the holding frame, steel ball assembly. The shaft ring is the collar that is in line with the shaft, the seat ring is the collar that is in line with the bearing seat hole, and the gap between the shaft, the thrust ball bearing can only withstand the axial load, the one-way thrust ball bearing can only withstand the axial load in one direction, the two-way thrust ball bearing can withstand the axial load in both directions, the thrust ball bearing can not limit the radial displacement of the shaft, The limit speed is very low, the one-way thrust ball bearing can limit the axial displacement in one direction of the shaft and housing, and the two-way bearing can limit the axial displacement in both directions.
Thrust roller bearings are used to withstand axial load-based shafts and radial combined loads, but radial loads must not exceed 55% of axial loads. Compared with other thrust roller bearings, these bearings have a lower friction factor, higher speed, and a centering performance. The rollers of the 29000 bearings are asymmetric sphere rollers, which can reduce the relative sliding of rollers and raceways in their work, and the rollers are long, large in diameter, the number of rollers, the load capacity is high, usually oil lubrication, individual low-speed cases can be lubricated with grease. In the design of selection, should be preferred; 80000 type thrust cylindrical roller bearings, 90000 thrust cone roller bearings and AXK thrust roller bearings can withstand one-way axial loads, which are much larger than the axial load capacity of thrust ball bearings, and take up less axial space. Thrust cylinder roller bearings and thrust roller bearings are suitable for low speed, and thrust conical roller bearings are slightly faster than thrust cylinder roller bearings
