This cylindrical roller bearing carries a single row of rollers guided by a polyamide cage (TVP2), with two ribs on the outer ring and one rib on the inner ring, corresponding to the NJ design. Bore diameter is 50.0 mm, outside diameter 90.0 mm, and width 23.0 mm, with a net mass of 0.567 kg. The limiting speed is 11100 1/min and the reference speed is 5300 1/min. The E design provides an optimized internal geometry for increased load carrying capacity. The rib arrangement makes this bearing a semi-locating type, allowing axial displacement in one direction while providing guidance in the other, which is useful for compensating thermal expansion of the shaft. Radial internal clearance C4 (Group 4) gives a larger clearance than standard, suitable where operating temperatures or shaft fits reduce running clearance. The polyamide TVP2 cage allows smooth roller guidance at the given speed range and is compatible with oil or grease lubrication.
