The 2204K self-aligning bearing is a double row 2204K bearing designed for applications requiring angular misalignment compensation. This self-aligning ball bearing 2204K features a bore diameter of 20 mm, outer diameter of 47 mm, and width of 18 mm, with a dynamic load capacity of 7.85 kN and static load of 3.02 kN. It operates effectively in temperature ranges from -30°C to +120°C, supporting moderate radial and axial loads. Commonly used in mining equipment, agricultural machinery, and conveyor systems, its double-row design enables ±3° self-alignment to accommodate shaft deflection or mounting errors. Key advantages include reduced friction, extended service life under misalignment conditions, and simplified maintenance. However, its load capacity is lower compared to spherical roller bearings, making it more suitable for medium-speed applications. The open-type construction requires proper lubrication for optimal performance.
