The 215 mm insulated cast iron sleeve bearing designed for use with 6224 and 6320 series bearings features an outer diameter of approximately 222.3 mm with a tolerance of ±0.05 mm and sleeve lengths available in 60 mm, 70 mm, and 80 mm. This sleeve bearing provides electrical insulation to prevent current flow through the bearing, enhancing durability in electric motor and industrial applications. It is engineered for compatibility with deep groove ball bearings such as the 6224, which has a bore diameter of 120 mm, an outer diameter of 215 mm, and a width of 40 mm, supporting dynamic loads up to 146 kN and operating speeds up to 4000 rpm with temperature ratings from -40 to 100 °C. The sleeve bearing’s robust cast iron construction ensures reliable performance under heavy radial loads and harsh conditions.
