ZKL 2220K C3 Double-Row Self-Aligning Ball Bearing

Description:

The ZKL 2220K C3 Bearing is used in industrial rotating equipment to support radial loads while accommodating shaft misalignment through its self-aligning design. Commonly installed in electric motors, conveyors, gearboxes, and heavy machinery where alignment deviations or shaft deflection may occur. Maintenance teams, mechanical engineers, and system integrators use this part for repair, retrofit, or replacement to ensure smooth operation, reduced wear, and extended equipment life.

Applications:

The ZKL 2220K C3 bearing is widely used in industrial machinery such as conveyor systems, pumps, fans, and agricultural equipment where shaft misalignment is common. Its double-row self-aligning design allows the bearing to automatically adjust to angular misalignment, reducing stress on components and improving reliability in demanding environments. It is especially suitable for applications with heavy radial loads and moderate axial loads in both directions.
