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.

The application:

Gear reduction units

Cranes

Calendar rolls

Industrial machinery

Heavy-duty gear drives

Various industrial configurations

Sheaves

Crane sheaves

Oil-field drilling rig sheaves

Applications where two-row preset bearings are required

Automotive configurations
