The 120 mm insulated steel sleeve bearing compatible with bearing numbers 6213 and 6311 features an outer diameter of approximately 126 mm (±0.05 mm) and a sleeve length of 70 mm. The 6213 deep groove ball bearing has an inner diameter of 65 mm, outer diameter of 120 mm, and width of 23 mm, with a basic dynamic load rating of 57,500 N and a maximum rotation speed of 5,300 rpm. It is constructed from steel with a pressed cage retainer and is designed for radial load applications, offering high precision (Grade 0) and standard clearance (CN). The 6311 bearing variant has a 55 mm bore, 120 mm outer diameter, and 29 mm width, suitable for similar applications requiring robust load capacity and durability. These components are ideal for high-speed, heavy-duty mechanical systems requiring reliable performance and dimensional stability.
