The 215 mm insulated steel sleeve bearing designed for use with bearing numbers 6224 and 6320 features an outer diameter of approximately 222.3 mm with a tight tolerance of ±0.05 mm and is available in sleeve lengths of 60, 70, and 80 mm. This sleeve bearing is constructed from insulated steel, providing electrical isolation and durability for heavy-duty applications. It complements deep groove ball bearings such as the 6224 series, which have a bore diameter of 120 mm, an outer diameter of 215 mm, and a width of 40 mm, supporting high dynamic loads up to 146 kN and speeds up to 4000 rpm, with a temperature range from -40 to 100 °C. The sleeve bearing ensures proper fit and electrical insulation in rotating machinery setups.
