The 160 mm insulated steel sleeve bearing compatible with bearing numbers 6021, 6218, and 6315 features an outer diameter of approximately 166.3 mm ±0.05 mm and a sleeve length of 40 mm. Designed for electrical and mechanical applications, this sleeve bearing provides electrical insulation and mechanical support to the bearing assembly, enhancing durability and reducing electrical currents through the bearing. The 6315 deep groove ball bearing it pairs with has dimensions of 75 mm inner diameter, 160 mm outer diameter, and 37 mm width, supporting high radial loads and speeds up to 4,100 RPM with C3 internal clearance for thermal expansion. This bearing is shielded on both sides for protection against contaminants and pre-lubricated for maintenance-free operation, making it suitable for electric motors, industrial machinery, and automation systems. The steel sleeve bearing’s precise dimensions and insulation properties ensure reliable performance in demanding environments.
