YDTech® manufacturer of single' double' multi row tapered roller(inch or metric) bearings; supplier of tapered roller bearings 3000 series in china.

tapered roller bearings are separable into the components: outer ring, inner ring and roller assembly. they are designed to accommodate combined loads, simultaneously acting radial and axial loads. the projection lines of the raceways meet at a common point on the bearing axis to provide true rolling and low friction.

This bearing type can be used in a preload situation to obtain higher rigidity and better running accuracy of the shaft. Double-row and four-row Tapered roller bearings are designed to carry radial, and bi-directional axial loads.

the inner and outer ring raceways and rollers of this type of bearing are made with a taper so that the planes of the surfaces of the raceways and roller axis meet at a point. The rollers are guided by the cone back-face rib.

A single row tapered roller bearing can support a combined radial and axial load. the size of the angle is indicated by the calculation factor:, the larger the contact angle. A single row tapered roller bearing is typically adjusted against a second tapered roller bearing.

tapered roller bearings utilize conical rollers and raceways, arranged so that the rollers and raceways meet at a common apex. The rollers are guided by contact between the large end of the roller and a rib on the inner ring. This provides high capacity for radial and single thrust loads.
