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 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. The 6224 bearing supports high radial loads, operates at speeds up to 4000 rpm limiting (6300 rpm reference), and features a pressed steel cage with C3 clearance for reduced noise and maintenance. Temperature ratings range from -40 to 100 °C, making it suitable for industrial machinery, pumps, and agricultural equipment. The sleeve bearing’s robust cast iron construction ensures reliable performance under heavy load and electrical insulation requirements.
