Spherical plain bearing

Spherical plain bearing

Bearing introduction

Spherical plain bearings, also known as joint bearings, have a sliding contact surface which is an inner spherical surface and an outer spherical surface. Spherical plain bearings are generally used for low-speed oscillating motion (ie, angular motion). Since the sliding surface is spherical, tilting motion (ie, aligning motion) can also be performed within a certain range of angles. When the eccentricity of the support shaft and the bearing hole is large, it can still work normally.
Because spherical sliding bearings have large sliding contact areas and large inclination angles, most spherical plain bearings adopt special processing methods such as surface phosphating, galvanizing, chrome plating, or sliding contact surface lining, inserting, spraying, etc. .
Spherical plain bearings have large load capacity and impact resistance, and are resistant to corrosion, abrasion, self-aligning, lubrication or self-lubricating and non-lubricating dirt. Even if the installation is misaligned, it can work normally. Therefore, spherical plain bearings are widely used for low-speed oscillating motions, tilting motions, and rotational motions. Such as engineering hydraulic cylinders, forging machine tools, engineering machinery, automation equipment, automotive shock absorbers, water conservancy machinery and other industries.
