Ceramic thrust ball bearing 51200CE

Ceramic thrust bearings are specially designed to withstand axial forces, which are forces in parallel directions. Thrust bearings are also known as thrust bearings. Thrust ball bearing is a kind of separation type bearing, shaft ring and seat ring can be separated from the components of cage and steel ball. The shaft collar is a collar matching with the shaft, and the seat ring is a collar matching with the bearing seat hole, and there is a gap between the shaft; Thrust ball bearing can only bear axial load, one-way thrust ball bearing can only bear axial load in one direction, and two-way thrust ball bearing can bear axial load in two directions. Thrust ball bearing can not limit the radial displacement of the shaft, the limit speed is very low, one-way thrust ball bearing can limit the axial displacement of the shaft and the shell in one direction, two-way bearing can limit the axial movement in two directions.

Ceramic thrust ball bearing

Ceramic thrust ball bearing is used to bear the combined axial and radial load, but the radial load shall not exceed 55% of the axial load. Compared with other thrust roller bearings, this kind of bearing has lower friction factor, higher rotation speed and centering performance. The roller of type 29000 bearing is asymmetric spherical roller, which can reduce the relative sliding of roller and raceway in work, and the roller is long, large in diameter, large in number of rollers, and high in load capacity. Oil lubrication is usually adopted, and grease lubrication can be used in some low-speed cases. Priority should be given to selection in design and selection; Type 80000 thrust cylindrical roller bearing, type 90000 thrust taper roller bearing and type AXK thrust needle roller bearing, can withstand one-way axial load, it is much larger than thrust ball bearing axial load capacity, and the rigidity is large, occupy less axial space. Thrust cylindrical roller bearing and thrust needle roller bearing are suitable for low rotation speed. The rotation speed of thrust tapered roller bearing is slightly higher than that of thrust cylindrical roller bearing.
