INA - F-576887.RNA | Needle Roller Bearings | 30 × 42 × 17 mm

Details

These bearing is a high-precision, machined-type radial needle roller bearing designed without an inner ring. It is produced by INA specifically for high-radial-load industrial and automotive applications where radial space is highly limited. Allows the outer ring and needle cage assembly to be mounted independently. This simplifies installation, handling, and maintenance in complex assemblies. Material : Made of high-purity, heat-treated chrome steel (typically 100Cr6) equipped with a robust steel or molded polyamide guidance cage. Features are : High Load-to-Size Ratio, Excellent Running Accuracy, Low Section Height, Low Friction Operation, High Rigidity, Optimized Lubricant Flow, Enhanced Fatigue Life, Reduced Vibration, Logarithmic Roller Profiling, Enhanced Heat Dissipation. Applications : Textile Machinery, Construction & Agricultural Equipment, Printing Presses, Packaging Machinery, Woodworking Machinery, Paper Processing Mills, Conveyor Systems & Material Handling, Machine Tool Spindles & Workholding Systems. RNA=Needle Roller Bearing Without an Inner Ring.
