Product: Needle Roller Bearing without Inner Ring Category: sensor Key benefits — why you need this bearing Spacesaving design: Without an inner ring the bearing has a smaller radial envelope, letting you design more compact assemblies or fit bearings where innerring types won't fit. speed, lownoise operation: Engineered for smooth rotation, it reduces operational noise and supports speed shafts while maintaining stability. Durable and heatresistant performance: Made from bearing steel for long service life; designed to run with lower temperature rise and reduced risk of overheating under normal conditions. Simplified maintenance and reliable performance: Robust construction and consistent rolling behavior reduce wear and help extend maintenance intervals. What it does (function) Supports radial loads on rotating shafts using closely spaced needle rollers. Provides a lowprofile rolling element solution when the shaft or housing acts as the raceway (no inner ring required). Material and construction Item material: Bearing steel — hardened and finished for durability, wear resistance, and stable rolling contact. Number of columns: Single row needle rollers for compact radial support and uniform load distribution. Item performance: Low noise, speed, resistant to overheating, and long service life. Compatibility and use considerations Intended for applications where the shaft or housing can serve as the inner raceway (suitable shaft/housing hardness and surface finish required). used where a compact, speed radial bearing is needed and an inner ring would increase diameter or weight. Typical applications (practical examples) Automotive transmissions and gearbox shafts that require compact, speed radial support without an inner ring. Industrial gearboxes, pumps, or electric motors where space is limited and low vibration/noise is important. Precision machinery and automation equipment (robots, conveyors, printing) needing reliable, longlife radial bearings in tight assemblies.
