Tapered roller bearings can be separated from the inner ring with roller cage components together and the outer ring can be installed separately. As amended by the roller and raceway contact at the contact line can reduce the stress concentration. The tapered roller bearing can withstand large radial and axial load. Tapered roller bearings can only pass one-way axial load, axial load in the opposite direction to pass on another with symmetrical installation of tapered roller bearings. The tapered roller bearings, the largest amount of single row tapered roller bearings. In the front wheels of cars in recent years, using the small size of the double row tapered roller bearings. Four tapered roller bearings used in a large cold and hot rolling mill and other heavy machinery

The expression method of dimensions, bearing accuracy, symbols and definitions have been revised by iso.Our catalog has been revised in conformity with the jis and iso revisions. Basic load ratings have been revised with improvements in our materials and manufacturing techniques and according to iso 281/1-1997. The basic static load ratings are expressed in accordance with iso 76-1987
Taper roller bearings are generally used to support combined load mainly consisting of radial load. her cups are separable for easy assemble for easy assembling. During mounting and using, radial clearance and axial clearance can be adjusted and preloaded mounting can be made.
