1202 Self-Aligning Ball Bearing | Double Row Radial Bearings for Shaft Misalignment Compensation

The 1202 self-aligning ball bearing is a upgraded double-row radial bearing in the 1200 series, optimized for medium-speed and medium-load mechanical transmission scenarios. Adopting a unique spherical outer raceway structure, this open-type bearing features flexible self-alignment function, which effectively compensates for shaft deflection, assembly errors and equipment operating deviation. It can bear main radial load and auxiliary bidirectional light axial load, delivering low-vibration, stable and long-lasting operation for various general industrial mechanical systems.

1202 Self-Aligning Bearing Structure And Performance Advantages

Equipped with double-row precision steel balls and a separable inner ring design, the 1202 bearing boasts larger load-bearing contact area than smaller 1200 series models, with enhanced pressure resistance and operational stability. The open structure supports convenient regular lubrication and simple daily maintenance, effectively extending bearing service life. Its excellent misalignment tolerance solves common equipment failures such as shaft jamming, abnormal noise and accelerated wear caused by installation offset, making it suitable for long-cycle continuous working equipment.
