This cylindrical roller bearing carries radial loads through a single row of rollers guided by a machined M1 cage, with two ribs on the outer ring and one rib on the inner ring, giving the NJ design its semi-locating function in one axial direction. Bore diameter is 30.0 mm, outside diameter 62.0 mm, width 20.0 mm, and net mass 0.293 kg. The E design provides an increased roller complement for higher load capacity. Limiting speed reaches 21200 1/min, with a reference speed of 8000 1/min. Radial internal clearance is set to CN (Group N), suiting standard fit and operating temperature conditions without added preload. As a semi-locating bearing, it allows axial displacement of the non-guided ring, which accommodates shaft thermal expansion while the ribbed side provides axial support in one direction. The separable inner and outer rings simplify mounting and dismounting, and the machined cage supports stable roller guidance at the stated speed ratings.
