This tapered roller bearing carries combined radial and axial loads through a single row of tapered rollers set between cone and cup raceways, with a bore of 90.0 mm and an outside diameter of 150.0 mm. Main dimensions follow DIN 720, and the design is separable, allowing the cone assembly and cup to be mounted independently during fitting. Net mass is 3.147 kg, the cage is of standard design, and the limiting speed reaches 4450.0 1/min. The separable construction simplifies mounting and internal clearance adjustment during assembly, letting the cone and cup be set to the required axial position on the shaft and in the housing independently. As a single-row tapered design, it takes up axial load in one direction only, so it is typically paired with a second bearing to support load from the opposite side. The standard cage design and DIN 720 main dimensions make it interchangeable in terms of envelope size with other bearings of the 331 series sharing the same dimensional standard.
