Product Description PRODUCT DETAILSThe needle roller bearings without inner rings stand out with their streamlined design and robust performance. It abandons the inner ring structure and allows the needle rollers to directly adhere to the hardened shaft neck, achieving ultra-high load density with minimal radial space. Its load-bearing capacity is several times higher than that of ordinary bearings, making it easy to handle high load scenarios such as automotive parts and construction machinery. Although the maximum speed is limited by the absence of a cage, precise journal machining technology ensures stable operation and long-lasting lifespan, making it an efficient load-bearing solution for space constrained conditions.MORE PHOTOSCATALOGUEBearing No.Boundary Dimensions (mm)MassWithout InnerdFwDCr minkgRNAV 4902152028130.30.041RNAV 4903172230130.30.045RNAV 4904202537170.30.094RNAV 4905253042170.30.111RNAV 4906303547170.30.127RNAV 4907354255200.60.207RNAV 4908404862220.60.285RNAV 4909455268220.60.329RNAV 4910505872220.60.341RNAV 49115563802510.486RNAV 49126068852510.522RNAV 49136572902510.558RNAV 491470801003010.884RNAV 491575851053010.936RNAV 491680901103010.843RNAV 491785100120351.11.46RNAV 491890105125351.11.531RNAV 491995110130351.11.603RNAV 4920100115140401.12.225RNAV 4922110125150401.12.412RNAV 4924120135165451.13.337RNAV 4926130150180501.54.5RNAV 4928140160190501.54.791COMPANY INTRODUCTIONPRODUCTION PROCEDURERELATED PRODUCTSFUNCTIONOUR ADVANTANGE
