The 120 mm insulated cast iron sleeve bearing designed for use with 6213 and 6311 bearings features an outer diameter of approximately 126 mm with a tolerance of ±0.05 mm and a sleeve length of 70 mm. The 6213 deep groove ball bearing paired with this sleeve has an inner diameter of 65 mm, outer diameter of 120 mm, and width of 23 mm. It offers a basic dynamic load rating around 57,500 N to 58,500 N and supports radial loads with a maximum allowable rotation speed up to 7,500 rpm. The bearing is constructed with steel rings and balls, typically with a pressed steel cage, and is available in open or shielded types for enhanced protection and durability. This combination is suitable for applications requiring high load capacity and reliable rotational performance.
