INA - F-204754.02.RNU | Full Complement Cylindrical Roller Bearing | 42.01 × 72 × 30 mm

Details

INA F-204754.02.RNU is a full complement cylindrical roller bearing with inner diameter 42.01 mm, outer diameter 72 mm and width 30 mm. Additional specifications include bore type CYLINDRICAL, seal YES, cage YES and lubrication STANDARD.

These bearing is a single-row radial cylindrical roller bearing engineered without an inner ring. Manufactured by INA, it is designed for demanding industrial setups that prioritize radial load capacity over axial footprint space. The "RNU" classification implies a cylindrical roller design completely devoid of an integrated inner ring. The cage and outer ring assembly run directly on a hardened, ground, and polished machine shaft spindle. This reduces the overall envelope size while maximizing shaft thickness for radial rigidity. It features a cageless design completely packed with rolling elements. Without a cage taking up space, it maximizes the number of rollers to achieve the highest possible radial load capacity. Material : Constructed from premium GCr15 high-carbon chromium bearing steel for maximum wear resistance and structural stability. Features are : High-Speed Boundary Dynamics, Axial Displacement Flexibility, Low Initial Friction Torque, High Heat Stability, Logarithmic Roller Profiling. Applications : Metal Processing & Machine Tools, Material Handling, Construction & Earthmoving Equipment, Agricultural Machinery, Renewable Energy & Wind Turbines, Textile & Packaging Machinery. RNU=Without Inner Ring NU-Type.
