The 120 mm cast iron sleeve bearing designed for use with 6213 and 6311 bearings features an outer diameter of approximately 126 mm ±0.05 mm and a sleeve length of 70 mm, providing a robust fit for oversized bearing applications. 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. It supports high rotational speeds up to 7,500 rpm with a basic dynamic load rating around 58.5 kN and static load rating of 40.5 kN. The bearing is typically steel-made with options for metal shields or rubber seals for protection and durability in industrial environments. This combination ensures reliable radial load handling and extended service life in machinery requiring precise, high-speed rotation.
