Working temperature and oscillating motion of rod end spherical plain bearing

- Dec 07, 2018 -

The rod end spherical bearing is mainly composed of an outer spherical surface and an inner ring and an outer ring having an inner spherical surface during the production process, and can withstand a large load during use, and can be different according to the rod end joint bearing in use. The type and structure can withstand radial loads, axial loads or combined loads of radial and axial forces.

rod end spherical plain bearing can generally be used for low-speed oscillating motion, and can be tilted to a certain extent within a certain range of angles. Depending on its type and construction, it can withstand radial loads, axial loads or combined loads in both radial and axial directions. Rod end joint bearings are widely used in engineering hydraulic cylinders, forging machine tools, engineering machinery, automation equipment, automotive shock absorbers, water conservancy machinery and other industries.

The working temperature of the rod end spherical bearing is mainly determined by the paired material between the sliding surfaces of the bearing. Specially, the sliding surface of the plastic material of the self-lubricating joint bearing has a tendency to decrease its load capacity at high temperatures. For example, 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.
