This tapered roller bearing carries combined radial and axial loads through a single row of tapered rollers set between a cone and a separable cup, with main dimensions built to DIN 720. Bore diameter is 17.0 mm, outside diameter 40.0 mm, net mass 77.7 g, and the limiting speed reaches 20100 1/min. The cage is of standard design. Because the cup and cone assembly separates, mounting and adjusting the internal clearance can be done independently on the shaft and housing side, which simplifies fitting and preload setting. The single-row tapered geometry directs load along the roller axis, making the bearing suitable where combined radial and axial forces act in one direction and where precise axial positioning is required. As supplied, the bearing carries no seal or integrated lubrication, so grease or oil supply and sealing arrangements must be provided by the surrounding housing design.
