This single-row cylindrical roller bearing has an inner diameter of 45.0 mm, outer diameter of 85.0 mm, and width of 19.0 mm, with a net mass of 0.432 kg. It is built with two ribs on the outer ring and one rib on the inner ring, type NJ, giving it a semi-locating function that allows axial displacement in one direction while guiding the shaft in the other. The polyamide TVP2 cage carries the rollers, the E design provides increased load capacity, and radial internal clearance is C4 (Group 4). Limiting speed is rated at 10200 1/min, with a reference speed of 7000 1/min. The semi-locating arrangement suits applications where the shaft needs axial support in one direction while permitting thermal expansion or movement in the other. The C4 clearance accommodates thermal growth and interference fit conditions without inducing excessive preload, making the bearing suitable for duties with elevated operating temperatures or tighter fits. The TVP2 cage design supports stable roller guidance at the rated speeds, and the E construction allows higher radial load carrying capability within the given envelope dimensions.
