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

Details

INA F-27991.03.NKIA is a needle roller bearings with inner diameter 17 mm, outer diameter 38 mm and width 55 mm. Additional specifications include bore type CYLINDRICAL, seal YES, cage YES and lubrication STANDARD.

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.
