Joint bearings are widely used in hydraulic engineering, metal forming machine, construction machinery, automation equipment, automotive shock absorbers, irrigation machinery and other industries. Joint flanged ball bearing joint bearing Introduction and high precision bearings classification is spherical plain bearings, the basic type is composed of a spherical sliding spherical contact surface the inner and outer components. Depending on their structure and types, can withstand radial load, axial load, or radial, axial joint load.
Because spherical plain bearings of sliding contact area, the tilt angle is large, but also because most of the plain bearings taken a special process methods, such inch bearing as surface phosphate, zinc, chrome or outside the sliding surface lining, insert pads, such as spraying, Therefore, greater load capacity and impact resistance, and has anti-corrosion, wear resistance, self-aligning, self-lubricating lubrication good or dirt contamination without lubrication characteristics, even dislocation can be installed to work properly. Therefore, joint bearings are widely used for slower swing motion, tilt and rotation movement.
Composition
Plain Bearings mainly by an outer ring and an inner ring. Taper roller bearings The spherical inner and outer spherical outer ring composed of sliding friction.
