Double row tapered roller bearings

Tapered roller bearings have tapered inner and outer ring raceways and tapered rollers. The bearings are not self-retaining. As a result, the inner ring together with the rollers and cage can be fitted separately from the outer ring. 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. They are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads. The axial load carrying capacity of tapered roller bearings increases with increasing contact angle (α). The size of the angle is indicated by the calculation factor e ：the larger the value of e, the larger the contact angle. 

Double row tapered roller bearings can carry heavy loads and are stiff. They are suitable for the accommodation of combined (radial and axial) loads and can locate a shaft axially in both directions with a given axial clearance or a given preload. Their main use is in gearboxes, hoisting equipment, rolling mills and machines used in the mining industry, e.g. tunnelling machines.

▲   The design’s of all these tapered roller bearings are based on standard structures; LYNBC can design and manufacture many other similar structures in accordance to the special and particular requirements of their customers’. If our customer’s have specific requests then the customer should identify the structure, and mounting dimensions that are required. Please contact the LYNBC Technical Center if you need any assistance in this area.
