This needle roller bearing carries radial loads within a compact cross-section, using a two-row needle roller set without an inner ring and without ribs on the outer ring. Outside diameter is 35.0 mm, net mass is 82.2 g, limiting speed reaches 18100 1/min and reference speed is 11200 1/min. Symbol RNAO25X35X26 identifies this design. The absence of an inner ring and ribs means the shaft surface must act as the running track and provide axial guidance for the needle rollers, so the mating shaft has to be hardened and ground to the tolerance required for direct rolling contact. The two-row arrangement increases radial load capacity and running stability compared to a single row within the same envelope, while the given speed limits set the upper boundary for continuous operation. RNAO25X35X26 suits installations where radial space is limited and the housing bore is machined to accept the outer ring directly, with lubrication applied according to the operating speed and load conditions at assembly.
