The 160 mm cast iron sleeve bearing compatible with bearing numbers 6021, 6218, and 6315 features an outer diameter of approximately 166 mm (6.535") with a tolerance of ±0.05 mm and is available in lengths of 40, 50, and 60 mm. The insulated version has an outer diameter of 166.3 mm (6.547") and a length of 40 mm, designed to provide electrical insulation and reduce shaft currents. The 6315 deep groove ball bearing, often paired with these sleeves, has an inner diameter of 75 mm, an outer diameter of 160 mm, and a width of 37 mm, supporting high rotational speeds and dynamic loads with steel construction and various sealing options for protection and durability. These components are ideal for industrial rotary applications requiring precise fit and electrical isolation.
