Tapered Roller bearings double-row

Double row tapered roller bearings in the TDO  and TDI  designs, in many variants and with different features (→ Designs and variants). Depending on the design, these bearings can accommodate heavy radial loads, axial loads in both directions and have a high degree of stiffness. Double row tapered roller bearings are typically used in gearboxes, hoisting equipment, rolling mills and machines in the mining industry, e.g. tunnelling machines.

Because of their second row of rollers, double row tapered roller bearings are suitable for heavy radial and axial loads. The axial load carrying capacity of tapered roller bearings increases with increasing contact angle α. The size of the contact angle, which is usually between 10° and 30°, is related to the calculation factor e (→ product tables): the larger the value of e, the larger the contact angle.

​Double- or two-row tapered roller bearings feature double cups and two single cones. They are available in a variety of configurations for general industrial and automotive applications.
