INA - F-27991.03.NKIA | Needle Roller Bearings | 17 × 38 × 55 mm

Details

These bearing is a high-precision combined component from INA brand. While often categorized broadly alongside industrial roller series, the "NKIA" designation specifically signifies a needle roller / angular contact ball bearing assembly. This dual configuration allows it to handle high radial forces alongside single-direction axial loads in highly compact machinery footprints. Features a radial needle roller assembly integrated directly with an angular contact ball bearing segment. Material : Made from high-fatigue, through-hardened carbon-chromium bearing steel (typically 100Cr6 or SAE 52100). Features are : Multi-Directional Load Management, Non-Separable Design, Low Heat Generation, Relieved Roller Profiles, Maintenance & Service Life, Superfinished Raceways, Low Boundary Friction, Vibration Damping. Applications : Machine Tool Spindles, Automation and Robotics, Automotive, Transmissions & Powersports, Heavy Construction & Material Handling, Power Generation & Energy Infrastructure, Medical, Scientific & Laboratory Equipment. NKIA=Needle Roller / Angular Contact Ball Bearing.
