The 120 mm cast iron sleeve bearing designed for use with 6213 and 6311 ball bearings features an approximate outer diameter of 126 mm with a tolerance of ±0.05 mm and a sleeve length of 70 mm. This sleeve bearing is engineered for durability and precise fitment in rotary applications, providing stable support and reducing wear on the bearing assembly. The 6213 deep groove ball bearing compatible with this sleeve has an inner diameter of 65 mm, outer diameter of 120 mm, and width of 23 mm, with a basic dynamic load rating around 58.5 kN and a reference speed up to 12,000 rpm. It is available in open, shielded, or sealed variants, suitable for high-speed and high-load conditions in industrial machinery. The sleeve bearing’s cast iron construction ensures robust performance in demanding environments.
