2.Oscillating bearing , or bushings, are metal-on-metal bearings consisting of a spherically ground inner ring housed in a mating outer ring without any rolling elements. While all plain bearings are precision ground and made from through-hardened steel, custom orders are available and can include special materials, clearances, surface finishes or configurations to accommodate unique applications. Size range: Available from 12.7 mm - 600 mm (0.500 in. to 23.622 in.) bore
radial spherical plain bearings requiring maintenance have the sliding contact surface combination steel-on-steel. Bearings with this sliding contact surface combination require regular relubrication. The high wear resistance of the sliding surfaces makes these bearings especially suitable for bearing arrangements where heavy loads of alternating direction, shock loads or heavy static loads have to be accommodated. Bearings which have cylindrical extensions at both sides of the inner ring are intended for applications where normally spacer sleeves are arranged at either side of the bearing, or are specially designed for the bearing arrangements of hydraulic cylinders.
Spherical plain joint bearing is Self lubrication bearing, and it can beara large load, such as bearing radial load, axial load or combined radial and axial load.
Joint bearings are widely used in engineering hydraulic cylinders, forging presses, construction machinery, automation equipment, automotive shock absorbers, hydraulic machinery and other industries.
