Centripetal bearing installation requirements
May 28, 2018

The allowable working temperature of the radial joint bearing during operation is mainly determined by the mating material between the sliding surfaces of the bearing. When used, the sliding surface of the plastic material of the self-lubricating joint bearing is especially used at high temperatures. The bearing capacity tends to decrease. For example, when the sliding surface material of the lubricated joint bearing is steel/steel, the permissible operating temperature depends on the permissible working temperature of the lubricant. However, for all lubricated and self-lubricating joint bearings, they can be used within the temperature range of -30°C to +80°C, and they can maintain the correct bearing capacity.

The inclination of the radial joint bearing

The inclination angle of the radial spherical plain bearing is much larger than that of the ordinary adjustable roller bearing when it is in use. It is very suitable for use in the support position where the concentricity requirement is not high during the operation. In general, the inclination of the joint bearing will follow. With its bearing structure size, type and sealing device and the different forms of support, the general angular direction of the radial spherical plain bearing is 3 ° ~ 15 °, the angle of inclination of the angular contact spherical plain bearing is 2 ° ~ 3 °, thrust spherical plain bearing The dip range is 6° to 9°.

In any case, the radial joint bearing shall not be deformed unevenly by the selected fitting of the product. The selection of the mating nature and grade must be based on the bearing type, bearing type and load size and other working conditions. Decision.

Displacement of radial joint bearings

The force applied to the assembly and disassembly of the radial spherical joint bearing cannot be directly transmitted through the spherical sliding surface. During the operation, it should effectively use its auxiliary loading and unloading tools, such as its sleeve, detacher, etc., to apply external loading and unloading force. Apply directly and evenly to the mating ferrule, or load-free loading and unloading with auxiliary methods such as heating.

Centripetal bearing installation

When the spherical joint bearing is operated, when assembling the series of joint bearings, it is necessary to keep the position of the accidental split surface in particular. To prevent the load from directly acting on the split surface during use, it is necessary to maintain the split surface in conformity with the direction. Right angle direction.
