The NJ205 cylindrical roller bearing features a 25 mm bore diameter, 52 mm outside diameter, and 15 mm width, designed for high radial load capacity and low friction. It has a basic dynamic load rating around 28.5 to 32.5 kN and a static load rating near 26.7 to 27 kN, supporting speeds up to 12,000 RPM with grease lubrication and 15,000 RPM with oil. Constructed from high chromium bearing steel with a caged roller design, it offers a separable inner ring with one rib and an outer ring with two ribs for axial location in one direction. The bearing is unsealed and suitable for applications like electric motors, pumps, and gearboxes.
