The 170 mm steel sleeve bearing compatible with bearing numbers 6022, 6219, and 6316 features an outer diameter of approximately 177 mm with a tolerance of ±0.05 mm and a sleeve length of 80 mm. These sleeves are designed for use with single row deep groove ball bearings, which typically have bore diameters around 110 mm, outer diameters of 170 mm, and widths of 28 mm. The bearings are made from high-quality chrome steel (SAE52100) offering low friction, high rigidity, and silent operation, suitable for high-speed applications and capable of handling both radial and axial loads. Sealing options include Z, ZZ, RS, and 2RS for protection against contaminants. These components are widely used in heavy machinery, automotive, agriculture, and industrial sectors. The sleeve ensures proper fit and alignment for optimal bearing performance and longevity.
