Guides and supports rotating machine elements along a track while carrying both radial and axial loads through a single row of needle rollers running on a particularly thick-walled outer ring. The needle roller bearing NATR40-PP-A has a bore diameter of 40.0 mm, an outside diameter of 80.0 mm and a net mass of 0.795 kg. The design consists of a needle roller and cage assembly combined with an inner ring, while axial guidance of the outer ring is achieved through plastic axial plain washers and contact washers. Sealing is provided on both sides by plastic axial plain washers arranged in a three-stage configuration (PP), which keeps contamination away from the raceway and retains lubricant within the bearing. The thick-walled outer ring and integrated axial guidance allow the bearing to run directly on a track surface without a separate housing, making it suitable for applications where combined radial and axial guidance along a fixed path is required.
