Application Case | Joint Bearing: Reliable Transmission Support Point for Heavy Load Oscillating Conditions

Joint bearings, as the core flexible hinge components in equipment, rely on spherical sliding structures to withstand radial and axial combined loads, and can also adapt to certain angles of oscillation and inclination compensation. They are widely used in various heavy-load, vibration, and angle-offset working conditions.

✅ Construction machinery
Excavators, loaders, hydraulic cylinders of cranes, connecting rod hinge parts. During equipment operation, there is continuous oscillation and large impact loads, and joint bearings can compensate for installation deviations, buffer vibrations, reduce cylinder sticking, improve the stability of the entire machine, and extend the service life of the hinge points.

✅ Mining & Metallurgical equipment
Mine cars, crushers, metallurgical vibration mechanisms. With large dust and strong load impact, self-lubricating joint bearings are selected, which do not require frequent addition of lubricating grease, reducing on-site maintenance costs, and are suitable for harsh industrial and mining environments.

✅ Agricultural equipment
Large harvesters, seeders, agricultural spraying machinery connecting rods and steering mechanisms. In field conditions, there is roughness, much sand, and joint bearings can adapt to repeated oscillations, withstand erosion by mud and water, and ensure the continuous operation of agricultural machinery for a long time.

✅ Wind power equipment
Wind turbine tower lock plates, pitch connecting rods, yaw hinge mechanisms. They withstand alternating loads, have frequent angle oscillations, and have high requirements for wear resistance and fatigue resistance. They are key components for the safe operation of wind turbine units.

✅ Hydraulic cylinders, automation equipment, special vehicles
Hydraulic cylinder ear shafts, special vehicle suspensions, swing mechanisms. They compensate for assembly coaxiality errors, absorb deformation, and avoid stress damage caused by rigid connections.
