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)Basic load ratings(N)Limiting speeds(rpm)Mass(g)FwDCCrCorOil RNAV400221.8732171080029800450045RNAV400324.335181790037900430062RNAV400428.7422228150609003900114RNAV400533.5472233800708003700129RNAV400640.1552549900965003500193RNAV400745.96227476001228003100259RNAV400851.66828499001379002700304RNAV400957.47530525001535002600390RNAV401062.18030557001660002500426RNAV401169.89035685002258002300645RNAV401274.69535754002390002100677RNAV401380.310035795002569001900692RNAV40148811040988003549001700950RNAV401592.71154510180037290016001000RNAV4016100.31254510290037350015001400RNAV4017104.81304510380037480014001540COMPANY INTRODUCTIONPRODUCTION PROCEDURERELATED PRODUCTSFUNCTIONOUR ADVANTANGE
