This cylindrical roller bearing supports radial loads while allowing free axial displacement between shaft and housing, as it is designed as a non-locating bearing with two ribs on the outer ring and a smooth inner ring. The single-row NU203-E-XL-TVP2-C3 has a bore diameter of 17.0 mm, an outside diameter of 40.0 mm, and a width of 12.0 mm, with a net mass of 66.3 g. The limiting speed is 26500.0 1/min and the reference speed is 15300.0 1/min. The bearing uses a TVP2 cage and features the C3 radial internal clearance (Group 3), which compensates for thermal expansion during operation. Running accuracy is held to P6 tolerance, and the E design provides increased load carrying capacity. The axial freedom of the non-locating design makes it suitable for mounting positions where the shaft requires compensation for length changes.
