Joint Bearing

SKF Joint Bearings for Articulated Industrial Equipment

Joint bearings, also called spherical plain bearings in many applications, are used where an articulated connection must support oscillating or slow rotary movement. Typical uses include linkages, hydraulic equipment, construction machinery, agricultural mechanisms and industrial actuators. Selection begins with the full reference and the load direction at the joint.

Selection Details to Check

• Bore size, outer diameter, width and the complete bearing designation.
• Radial and axial load direction, oscillation angle and movement frequency.
• Housing and shaft fit, lubrication requirement and environmental exposure.
• Whether the installation needs a maintenance-free or relubricable arrangement.

Application Review

The working conditions at an articulated joint affect bearing choice. Shock load, contamination, corrosion, lubrication access and installation alignment should be considered before replacing a unit. Supply the equipment model or a clear photograph of the bearing marking when requesting a quote.

Joint Bearing FAQ

How do I identify the correct joint bearing?

Use the complete reference, bore size, outer diameter, width and the loading/movement information from the equipment.

Is lubrication information important?

Yes. The required lubrication method and service conditions can determine whether a particular bearing configuration is suitable.
