The 75 mm steel shaft sleeve bearing is compatible with bearing numbers 6015, 6215, and 6315, featuring a sleeve length of 75 mm and available in undersizes of 2 mm, 3 mm, and 4 mm to fit bores of 73 mm, 72 mm, and 71 mm respectively. These sleeves provide precise fitment for deep groove ball bearings commonly used in industrial applications. For example, the 6015 bearing measures 75 mm inner diameter, 115 mm outer diameter, and 20 mm width, while the 6215 bearing has dimensions of 75x130x25 mm with dynamic load ratings up to 15,160 lbs and limiting speeds up to 5,800 RPM. The 6315 bearing typically measures 75x160x37 mm with a dynamic load rating of 113,000 N and a maximum speed of 4,300 RPM. These components are made from high-quality steel, ensuring durability and reliable performance in heavy machinery and automation systems.
