30303 Taper roller bearings Features:

a,high speed, high precision
b,high rigidity, stand impact and vibration
c,can withstand big axial load


This bearing is suitable to bear composite load of axial load and radial load. Normally radial load is predominant but for great taper angle bearing the axial load could be predominant. 

Taper roller bearing is a separable bearing. Its outer ring can be mounted individually from the unit of inner ring, cage and rollers. Its radial and axial internal clearance can be adjusted during installation; even can be a interference installation. For taper roller bearing stamped steel cage is common selection. For large size bearing, welded steel cage or pin-assembled cage is used.
