GQZ RNA6916 Double Row Machined Needle Roller Bearing 90×110×54mm Without Inner Ring For Limited Installation Space
RNA6916 is double row solid machined needle roller bearing without inner ring. It only contains outer ring, needle rollers and cage assembly. The shaft surface needs quenching and grinding to act as raceway. It features ultra-high radial load capacity, compact cross-section and allows limited bidirectional axial displacement. Open structure supports convenient re-lubriion maintenance. Widely applied on hydraulic motors, industrial gearboxes, construction machinery, agricultural equipment and compact layout heavy-load rotary assemblies.
