Tapered roller bearing

Double-row tapered roller bearings. Please contact me if you need more information. Because of more rows of rollers, the radial load capacity of double-row tapered roller bearings enhanced, at the same time, they are capable of carrying heavier axial loads in both directions. They are primarily used to carry combination of radial and axial loads, and limit axial displacement of the shaft (or housing) in both directions, so they can be used to locate axially in both directions. The performance of the type TDO double-row tapered roller bearings is the same as the two single-row tapered roller bearings with back-back arrangement. The double-row tapered roller bearings are easy to mount and dismount, and have high stiffness; therefore, they are usually used in the applications with changing loads, such as gear-boxes, etc. There is a spacer between the two inner rings, the radial and axial clearance can be adjusted by changing the width of spacers. The type TDI double-row tapered roller bearings have a outer ring spacer, the clearance is adjustable, these bearings mainly used in roll neck under moderate loads. Sized from 0.6250" (16 mm) inside diameter to 10.1250" (257 mm) outside diameter. Metric ISO sizes from 15 mm inside diameter to 160 mm outside diameter. Both NTN and NTN-Bower brand names are available.
