A double-row tapered roller bearing is a common bearing type that consists of two tapered rollers mounted on an inner ring and an outer ring. It can withstand large radial and axial loads and is able to maintain high accuracy and stiffness while rotating at high speeds.Double row tapered roller bearings are designed so that the inner and outer rings can be adjusted separately to achieve axial and radial preloading.

Tapered roller bearings are separated bearings, and the inner and outer rings of the bearings are equipped with tapered raceways. This kind of bearing is divided into single row, double row and four row tapered roller bearings and other different structural types according to the number of rows of rollers installed. Single-row tapered roller bearings can withstand radial loads and axial loads in a single direction.

A single-row tapered roller bearing has an outer ring, and its inner ring and a group of tapered rollers are enclosed by a basket cage into an inner ring assembly, and the outer ring and the inner ring assembly can be separated. In addition, single-row tapered roller bearings can adjust the size of the clearance during installation.
