Taper roller bearings have tapered inner and outer ring raceways between which tapered rollers are arranged. The projection lines of all the tapered surfaces meet at a common point on the bearing axis
Taper roller bearings are generally used to support combined load mainly consist 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. Tapered roller bearings are widely used in automotive, mill, mining, metallurgy, plastics and machinery.
The boundary dimensions of metric single row tapered roller bearings listed in the product tables conform to ISO 355-1977 .
The inner rings with roller and cage assembly and outer rings of tapered roller bearings having the same designation are interchangeable. The tolerance for the total abutment width T of the bearing will not be exceeded if the cones and cups are interchanged.
