RNA69/32 Double Row Needle Roller Bearing 40x52x36mm Without Inner Ring High Radial Load For Hydraulic Motors Reducers

• RNA69/32 is an open double-row solid outer ring needle roller bearing without inner ring, standard dimension 40×52×36 mm. Precisely manufactured from premium GCr15 bearing steel, it adopts stamped steel cage to stably retain two rows of needle rollers inside the integral flanged outer ring.Without independent inner ring, the quenched and precision-ground shaft surface directly acts as the rolling raceway, which greatly saves radial installation space and allows larger-diameter shaft design to improve shaft structural strength. It boasts ultra-high radial load capacity and excellent rotational rigidity. The open structure facilitates regular grease replenishment and maintenance, widely used for compact heavy-duty transmission devices across various industrial fields.
