This single-row cylindrical roller bearing carries the NJ design with two ribs on the outer ring and one rib on the inner ring, giving it axial guidance in one direction while allowing free axial displacement in the other. Bore diameter is 17.0 mm, outside diameter 40.0 mm, width 16.0 mm, and net mass is 0.092 kg. The reinforced E design increases roller size and load capacity within the same envelope dimensions. The bearing runs with a TVP2 polyamide cage and radial internal clearance C3, and is rated for a limiting speed of 26500 1/min and a reference speed of 13200 1/min. Because it acts as a semi-locating bearing, it can absorb axial displacement caused by shaft expansion while still transmitting radial loads with the precision of the E design. The C3 clearance compensates for interference fits and thermal growth during operation, and the TVP2 cage supports stable roller guidance at the specified speed ratings. As an open bearing, it requires separate sealing and lubrication suited to the operating environment.
