Double inner double row tapered roller bearings inch

SKF manufactures 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.
Bearing features
High load carrying capacity
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.
Axial loads in both directions
Double row tapered roller bearings locate the shaft in both directions with a specific axial clearance or preload.
High stiffness
Double row tapered roller bearings provide a stiff bearing arrangement.
Low friction
The optimized roller end design and surface finish on the flange (fig. 3) promote lubricant film formation, resulting in lower friction. This also reduces frictional heat and flange wear. In addition, the bearings can better maintain preload and run at reduced noise levels.
