SKF 2220-KM Double-Row Self-Aligning Ball Bearing

Description:

The SKF 2220-KM Self-Aligning Ball Bearing is used to support rotating shafts while compensating for shaft misalignment in industrial power transmission systems. Commonly installed in electric motors, conveyors, pumps, fans, gearboxes, agricultural machinery, and heavy industrial equipment requiring a double-row self-aligning bearing with a tapered bore. Maintenance teams and system integrators use this bearing for equipment replacement, preventive maintenance, and restoration of smooth, reliable shaft operation.

Applications:

The SKF 2220-KM Self-Aligning Ball Bearing is commonly used in industrial gear reducers, conveyor systems, paper mills, textile machinery, mining equipment, agricultural equipment, fans, and electric motors where shaft deflection or mounting misalignment may occur. Its self-aligning design helps reduce bearing stress, improve service life, and ensure reliable operation under varying load conditions.
