The 1308 Self-Aligning Ball Bearing is a double-row bearing specifically designed to accommodate shaft misalignment and deflection during operation. With its spherical outer raceway, this bearing automatically adjusts alignment, ensuring smooth rotation and reducing internal stress.
Compared to smaller series, the 1308 bearing offers higher load capacity and improved structural strength, making it suitable for medium to relatively heavy industrial applications. It performs reliably in systems where shaft bending, vibration, or installation inaccuracies may occur.
Manufactured from high-quality chrome steel and available in stainless steel or special material options, the 1308 bearing delivers low friction, stable performance, and extended service life.
