1209K Self-Aligning Ball Bearing 45mm ID x 85mm OD with 4° Misalignment Compensation

The 1209K self-aligning ball bearing is a precision-engineered double-row bearing featuring a spherical outer ring raceway. This design compensates for shaft misalignment, axial deformation, and housing deformation, allowing up to 4 degrees of angular misalignment (1.5 degrees for sealed versions).

• Compensates for shaft misalignment up to 4 degrees
• Available with cylindrical or tapered bore (1:12 taper)
• Multiple sealing options for different environments
• Various cage materials for different applications
• Precision grades suitable for various industrial requirements

Our manufacturing facility operates under ISO9001:2015 quality management, ISO14001:2015 environmental management, and OHSAS18001:2007 health and safety standards. We utilize comprehensive testing equipment including hardness testers, roundness machines, roughness testers, noise and BVT testing machines, clearance instruments, and dimensional measurement tools. All raw materials undergo chemical composition testing to ensure product longevity.

Self-aligning ball bearings are widely used in agricultural machinery, blowers, precision instruments, low-noise motors, automotive applications, motorcycles, textile printing and dyeing machinery, paper making equipment, woodworking machinery, power stations, metallurgy, spraying systems, rolling mills, mining operations, cement plants, petroleum industries, chemical processing, and fitness equipment.
