The NACHI NU310 cylindrical roller bearing features a 50mm bore diameter, 110mm outer diameter, and 27mm width, designed for heavy radial load capacity and high-speed applications. It has a basic dynamic load rating of 87,000 N and a static load rating of 86,000 N, with a minimum radius (R) of 2mm. The bearing supports grease lubrication speeds up to 5,600 rpm and oil lubrication speeds up to 6,700 rpm. Its rolling elements are precisely ground and crowned to reduce edge loading and accommodate shaft misalignments. The bearing is separable, facilitating easy mounting and dismounting, and uses high-quality Japanese steel for enhanced durability.
