Product DescriptionProduct DescriptionMACHINED NEEDLE ROLLER BEARING WITHOUT INNER RINGMachined needle roller bearings are particularly suitable for applications where radial installation space is limited due to their small radial cross-sectional size, good bearing rigidity, and high radial load carrying capacity. Needle roller bearings can only withstand pure radial loads and cannot limit the axial displacement between the shaft and the housing. During bearing installation, the outer ring axis and the inner ring axis must not be tilted. Machined needle roller bearings have different structures with and without a cage for full complement needle rollers, and can also be specially designed and manufactured according to user requirements. Needle roller bearings with oil holes and grooves on the outer ring are beneficial for bearing lubrication. Lubricating oil or grease can be added to the bearings regularly as needed to ensure good maintenance and prolong their service life.PRECISION MACHINED CONSTRUCTION SUPERIOR MATERIAL QUALITY ENHANCED SURFACE HARDNESS Manufactured using advanced CNC machining technology to achieve exceptional dimensional accuracy and surface finish, ensuring optimal performance and extended service life.Constructed from premium-grade bearing steel with optimal carbon content and uniform grain structure for maximum durability and performance.Heat-treated to achieve optimal surface hardness, providing excellent wear resistance and fatigue life.Product ParametersShaft Diameter(mm)Bearing NumberBoundary Dimensions(mm)Basic Load Rating(N)Limiting Speed(Rpm)FwDCCr DynamicCor
