Because of more rows of rollers, the radial loading capacity of double-row tapered
roller bearings is enhanced, and they aslo can carry heavy axial loads in two directions.
They primarily carry combined loads which is main in radial, and limit axial displacement
of shafts or housings in two directions, so they can be as locating bearings in two
directions.
The performance of type TDO bearing is the same as two single-row tapered roller
bearings in back to back mounted.
Double-row tapered roller bearings have a small number of parts and high stiffness, and
are easy to be mounted and dismounted, therefore, they are usually used in the applications
with changing loads, such as decelerators and coiling machines. The radial and axial
clearance can be adjusted by changing the width of spacer between two inner rings.
Type TDI bearing is mainly used in roll necks with medium loads.This type of bearings
have a cup spacer, and the clearance is adjustable.
