INA - F-238902.01.RNN | Cylindrical Roller Bearings Without Outer Ring | 55 × 99.50 × 100 mm

Details

INA F-238902.01.RNN is a cylindrical roller bearings without outer ring with inner diameter 55 mm, outer diameter 99.50 mm and width 100 mm. Additional specifications include bore type CYLINDRICAL, seal YES, cage YES and lubrication STANDARD.

These bearing is a industrial-grade double-row cylindrical roller bearing without an outer ring. This bearing lacks a traditional outer steel ring. Instead, the dual rows of cylindrical rollers run directly against a hardened, precision-ground bore within your machinery's housing. This design saves critical radial space and reduces component weight. It features no retaining cage between the rollers. Maximizing the number of rolling elements provides the highest possible radial load rating in this footprint. Material : Manufactured from premium, through-hardened carbon-chromium bearing steel (100Cr6 / SAE 52100) for exceptional wear resistance and structural fatigue life. Features are : Non-Separable Assembly, Exceptional Shock Resistance, Axial Displacement Permissibility, High Rotational Stability, Low Initial Starting Torque, Excellent Vibration Damping. Applications : Construction & Mining Equipment, Renewable Energy & Power Generation, Printing Machinery, Semiconductor Manufacturing Equipment. RNN=Double-Row Radial Cylindrical Roller Bearing Without an Outer Ring.
