The 215 mm cast iron sleeve bearing designed for bearing numbers 6224 and 6320 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 robust support and insulation for deep groove ball bearings, enhancing durability and reducing wear. It is commonly paired with 6224 series bearings, which have a bore diameter of 120 mm, an outer diameter of 215 mm, and a width of 40 mm. These bearings support high radial loads, operate at speeds up to 4000 rpm (limiting) or 6300 rpm (reference), and feature pressed steel cages with C3 clearance for reduced noise and maintenance. The operating temperature range is typically -40 to 100 °C, making this combination suitable for industrial applications such as fans, pumps, and agricultural machinery. The sleeve bearing’s cast iron construction ensures strength and longevity in demanding environments.
