Guides and supports rotating machine elements along a track through a thick-walled outer ring designed to withstand radial load and edge contact. The NATR25-PP-A is a needle roller bearing with a needle roller and cage assembly and an inner ring, giving a bore diameter of 25.0 mm and an outside diameter of 52.0 mm at a net mass of 0.267 kg. Axial guidance of the outer ring is provided by plastic axial plain washers together with contact washers. Sealing is achieved in three stages by plastic axial plain washers fitted on both sides, marked PP, which keep contaminants out of the raceway while retaining lubricant inside the bearing. The particularly thick-walled outer ring allows direct rolling contact with a mating track surface, making this design suited for applications where the outer ring itself acts as the running surface rather than being fitted into a housing bore.
