This needle roller bearing guides a yoke roller along a track, carrying radial load through a full complement needle roller set running on a particularly thick-walled outer ring and a separate inner ring. Bore diameter is 50.0 mm, outside diameter 90.0 mm, and net mass 0.953 kg. Axial guidance of the outer ring is provided by plastic axial plain washers and contact washers on both sides. The plastic axial plain washers also form a three-stage seal on each side, keeping contamination out and retaining lubricant within the roller set, which suits continuous operation without frequent relubrication. The full complement needle roller set gives high radial load capacity for its cross-section, while the separate inner ring allows the bearing to be mounted directly on a shaft as a track roller running surface.
