Double Row Tapered Roller Bearings

Double row tapered roller bearings can support the combined load which is mainly consisted of radial load. It can restrict the axial displacement of the shaft or housing in the two directions and thus can be used as a bidirectional locating bearing. Double row tapered roller bearings can carry heavy radial and axial loads and are stiff, the axial load carrying capacity of tapered roller bearings increases with increasing contact angle, and are easy to be mounted and dismounted. Double row tapered roller bearings can be used in a preload situation to obtain higher rigidity and better running accuracy of the shaft. CJB provides both back-to-back arrangement (using one double cup and two single-row cones) and face-to-face arrangement (using two single-row cups and one double cone ). Their main use is in gearboxes, hoisting equipment, rolling mills and machines used in the mining industry.

Current product range: Ø d = 90 to 950 mm; max. Ø D = 1250 mm.
Detailed data about the product range can be found in CJB catalogues.
Possibility of delivery bearing types not listed in the catalogues should be discussed with CJB.
