This tapered roller bearing carries a single row of tapered rollers between a bore of 85.0 mm and an outside diameter of 170.0 mm, with a net mass of 4.728 kg. Main dimensions follow ISO 355, and the design is separable, allowing the inner and outer rings to be mounted independently. The cage is of standard design, and the limiting speed is rated at 4800 1/min. The separable construction simplifies mounting and dismounting on the shaft and in the housing, since the cone and cup assemblies can be fitted separately without affecting internal clearance. The tapered rollers and raceways are designed to take combined radial and axial loads acting in one direction, and the geometry allows adjustment of internal clearance during installation to match the required running accuracy. The bearing is intended for shaft arrangements where axial load capacity in a single direction, combined with radial support, must be achieved within the given bore and outside diameter.
