HR30314 J Construction Machinery Excavator Taper Roller Bearing 70x150x38.5mm

Taper roller bearing are generally used to support combined load mainly consisting of radial load. Their cups are separable for easy assembling. During mounting and using, radial clearance and axial clearance can be adjusted and preloaded mounting can be made.
Taper roller bearing are uniquely designed to manage both thrust and radial loads on rotating shafts and in housings.
Taper roller bearing are designed to carry both thrust and radial loads and consist of four components: the cone, or inner ring; the cup, or outer ring; the tapered rollers, or rolling elements; and the cage, or roller retainer.

The tapered roller bearing belongs to the separation type bearing. The inner and outer rings of the bearing have tapered raceways. This kind of bearing can be divided into single row, double row and four row tapered roller bearings according to the number of rows of rollers. Single row tapered roller bearing can bear radial load and single direction axial load. When the bearing bears the radial load, it will produce an axial component force, so it needs another bearing that can bear the axial force in the opposite direction to balance.
