This needle roller bearing guides the outer ring axially through plastic axial plain washers and contact washers, giving three-stage sealing on both sides via the plastic axial plain washers marked PP. The design uses a particularly thick-walled outer ring together with a full complement needle roller set and an inner ring, providing a bore diameter of 50.0 mm and an outside diameter of 90.0 mm, with a net mass of 0.951 kg. The thick-walled outer ring allows the bearing to carry radial loads while running directly as a track roller along a guide surface, with the inner ring supporting mounting on a shaft. The three-stage sealing arrangement on both sides restricts penetration of contaminants into the roller set, while the plastic axial plain washers take up axial guidance duties without requiring a separate flanging ring on the outer ring.
