Spherical plain bearings and rod ends

Spherical plain bearings and rod ends have no rolling elements. A spherical inner ring slides inside the outer ring, which lets the joint oscillate and take up angular misalignment; they are not meant for continuous high-speed rotation. Choose one by the load direction (radial, axial or combined), the kind of motion, the operating environment and how it will be mounted.

Letters name the series and the number gives the bore in millimeters. GAC 25 F, GAC 100 F and GAC 120 F belong to the GAC series of angular contact spherical plain bearings, which carry radial load plus axial load in one direction, with bores of 25, 100 and 120 mm. GAC 25 SA is a different design in the same size. Radial and axial types also exist, each with its own mounting and sealing options.

The sliding material pair decides maintenance. Steel-on-steel bearings need relubrication at intervals, while other designs run on a self-lubricating material. Common uses: hydraulic and pneumatic cylinders, steering linkages and suspensions, reciprocating machinery, and construction, farm and lifting equipment, anywhere the joint has to absorb misalignment without stressing the shaft.
