Product Details

Taper roller bearing are generally used to support combined load mainly consisting of radial load. Their cups are separable for easy assembling. During mounting andd using, radial clearance and axial clearance can be adjusted and preload mounting can be made.

Tapered roller bearing comprised by inner ring, roller , retainer and outer ring, which can be installed separately. This kind of bearing can support heavy radial load and axial load. Due to tapered roller bearing can only transfer one-way axial load, we need to install a symmetric tapered roller bearing to transfer the opposite direction axial load. This kind of bearing include single row , double-row and four-row tapered roller bearing according to the column number of roller. The clearance of single row tapered roller bearing need a adjustment during installation. And the clearance of double-row and four-row tapered roller bearing has been adjusted according to the users' requirement and need not to adjust.
