Product Description PRODUCT DETAILSNeedle roller bearings without inner rings stand out with their unique structural design. They ingeniously align the needle rollers directly with the hardened and ground journal, achieving high load-carrying efficiency through a minimalist structure. Compared with traditional bearings, its radial cross-section is significantly reduced, which can free up more space for equipment design and is an ideal choice for compact mechanical devices. The characteristics of a large number of needle rollers and small diameters endow them with excellent load distribution capabilities, enabling them to stably handle heavy-load working conditions while maintaining low operating resistance. Whether it is a precision component in an automated production line or a key transmission part in the aerospace field, needle roller bearings without inner rings have become indispensable precision elements in modern mechanical manufacturing with their reliable performance, helping equipment operate efficiently.MORE PHOTOSCATALOGUEShaft DiameterBearing No.DimensionsBasic Load RatingsLimiting
