Joint bearings are widely used in hydraulic engineering, metal forming machine tools, construction machinery, automation equipment, automotive shock absorbers, irrigation machinery and other industries. Joint bearing Introduction and classification of spherical plain bearings, the basic model is made with a sliding spherical contact surface the inner and outer components. Depending on the type of structure and can bear radial load, axial load, or radial, axial joint loads. Because of spherical plain bearing joints large contact area, tilt angle, but also because most of the bearings taken by a special process treatment, such as surface phosphate,zinc, chrome or outside the sliding surface lining, insert pads, spraying. So there is a greater load capacity and impact resistance, and has anti-corrosion, abrasion, self-aligning, self-lubricating without good lubrication or dirt contaminated lubricating characteristics, even if the installation misalignment can work. Therefore, joint bearings are widely used for slower swing motion, tilt and rotational movement. |
