The joint bearing has good wear resistance, can rotate freely, and is strong enough to withstand various loads from the outside. The life of the joint bearing is quite long and can be used flexibly. Such joint bearings are common in our lives. For example, where the piston rod of a hydraulic cylinder is connected to a fixed shaft, it is necessary to use a joint bearing. From the design point of view, the ordinary bearing can not satisfy such a high concentricity. Degree, just the joint bearing meets this performance.
Joint bearings are widely used in engineering hydraulic cylinders, forging machine tools, engineering machinery, automation equipment, automotive shock absorbers, hydraulic machinery and other industries. Joint bearing introduction and classification of spherical plain bearings, the basic type is composed of spherical sliding spherical contact surface The inner and outer rings are composed.
