Description

This tapered roller bearing carries combined radial and axial loads through a single row of tapered rollers set at an angle between the inner and outer ring raceways. Bore diameter is 55.0 mm, outside diameter 120.0 mm, and net mass 1.63 kg. The main dimensions follow DIN 720, and the design is separable, allowing the cone assembly to be mounted independently from the cup. The cage is of standard design, and the limiting speed is 7500 1/min. Because the bearing is separable, axial internal clearance can be set during mounting to match the specific shaft and housing arrangement, which is useful where controlled preload or adjustable clearance is required. The single-row tapered configuration supports load in one axial direction, so it is typically paired with a second tapered roller bearing arranged in opposition to take up loads from both directions. As supplied without integrated sealing, external sealing and lubrication provisions must be arranged in the housing design.
