This single-row cylindrical roller bearing (NJ208-E-XL-TVP2-C3) has a bore diameter of 40.0 mm, an outside diameter of 80.0 mm, and a width of 18.0 mm, with a net mass of 0.378 kg. The design features two ribs on the outer ring and one rib on the inner ring, forming a semi-locating bearing arrangement. It uses a TVP2 cage and is built to the E design for increased load-carrying capacity. Radial internal clearance is C3 (Group 3). The limiting speed is 12500 1/min, with a reference speed of 7500 1/min. The semi-locating design allows the bearing to accommodate axial displacement between the shaft and housing on one side while still providing radial guidance, which is a direct result of the rib configuration on the inner and outer rings. The C3 internal clearance compensates for thermal expansion during operation, and the polymer TVP2 cage supports smooth roller guidance at the given speed range. This configuration suits applications requiring separation of the inner and outer rings during mounting and where axial float must be accommodated on the non-locating side.
