Inclination and matching requirements for Radial Spherical Plain Bearings

- Sep 20, 2018 -

The allowable operating temperature of the radial joint bearing is mainly determined by the mating material between the sliding surfaces of the bearing, especially the sliding surface of the plastic material of the self-lubricating joint bearing. When the temperature is high, the bearing capacity will decrease, such as When the sliding surface material of a lubricated joint bearing is paired with steel/steel, the allowable operating temperature depends on the allowable operating temperature of the lubricant. However, for all lubricated and self-lubricating joint bearings, they can be used in the temperature range of -30 ° C ~ +80 ° C, and maintain the correct bearing capacity.

Inclination of radial bearing

The inclination of the radial spherical plain bearing is much larger than that of the generally adjustable rolling bearing. It is suitable for use in the finished part where the concentricity is not high. The inclination of the joint bearing varies with the size, type, sealing device and support form of the bearing. Generally, the inclination angle of the radial spherical plain bearing is 3° to 15°, the inclination angle of the angular contact joint bearing is 2° to 3°, and the inclination angle of the thrust joint bearing is 6° to 9°.

Coordination of radial bearing

In any case, the radial joint bearing should not use the ferrule to produce uneven deformation. The matching property and grade must be determined according to the bearing type, support form and load size. .
