Detailed description

Double-row tapered roller bearings
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 twdirections.
The performance of type TDO bearing is the same as two single-row tapered roller
bearings in back to back mounted.
Doublerow tapered roller bearings have a small number of parts and high stiffness,and are easy to be mounted anddismounted, 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 isadjustable.
