This needle roller bearing has a single row of rollers without an inner ring, giving an outside diameter of 47.0 mm and a width of 17.0 mm at a net mass of 71.5 g. Sealing is provided on both sides by lip seals (2RSR), and the cage is of standard design. The limiting speed is rated at 7500 1/min. The double-sided lip seal keeps out contamination and retains grease, so the bearing is suited for applications where the surrounding shaft acts as the raceway and protection against dirt ingress is required. Since there is no inner ring, the design allows a compact radial section while carrying radial loads, and the standard cage guides the needle rollers evenly around the circumference for stable running at the stated speed limit.
