7205E 30205 Tapered Roller Bearing

Tapered roller bearing is a kind of rolling bearing, its inner and outer rings are presented with a tapered raceway, the roller is also designed to be tapered, so that when the tapered surface is extended, its vertex will converge at a point on the bearing axis. This design enables the tapered roller bearing roller to achieve frictionless pure rolling on the raceway.

Technical parameter:

Structural features:

Tapered roller bearings are separate bearings in which the inner components (including the roller, cage and inner ring) can be easily separated from the outer ring, thus simplifying the installation process of the journal and housing. This design allows the inner bearing assembly and outer ring to be installed separately, allowing easy adjustment of radial and axial backlash.

Types and Specifications:

Tapered roller bearings can be divided into different structural forms such as single row, double row and four row according to the different number of roller rows. Single-row tapered roller bearings can withstand axial loads in one direction and are usually used in pairs to balance the additional axial components generated internally. Double and four-row tapered roller bearings can bear both radial and two-way axial loads, and are suitable for applications requiring high load capacity.
