Joint bearing

Joint ball bearings or radial spherical sliding bearings, abbreviated as joint bearings, have a simpler structure than rolling bearings. They are bearings that are installed together with an outer ring of an inner sphere and an inner ring of an outer sphere, and can rotate and swing at any angle during movement. After years of development, joint bearings have evolved into different types according to different usage environments, specifically:
Radial joint ball bearings, rod end joint bearings, thrust angle contact joint bearings. These types are further divided into maintenance type joint bearings and maintenance free joint bearings, which are commonly known as self-lubricating joint bearings. Joint bearings are widely used in engineering hydraulic cylinders, forging machines, engineering machinery, automation equipment, automotive shock absorbers, water conservancy machinery, and other industries.
