USMA BEARING 30306 TAPERED ROLLER BEARING 30306 JR BEARING

Tapered roller bearings are separable bearings, inner and outer rings have a tapered raceway.

This kind of bearing according to the number of columns loaded roller into single row, double row and four-row tapered roller bearings, such as different types of structures. Single row tapered roller
bearings can withstand the radial load and single direction axial load. When the bearing radial load, will
produce an axial force component, so when need another affordable bearing axial force in the opposite
direction to be balanced.
tapered roller bearing is able to carry radial and axial load in one directions simultaneously because an
axial component of produced when this type of bearing loaded radically, two bearing are used
together facing one another, or two or more bearing are matched and used.
Tapered Roller Bearing are designed such like cup. Cone and rollers have tapered surfaces

whose apexes converge at a common point on the bearing axis.
