Double Row Tapered Roller Bearing

1. Features: The double row taper roller bearing is mainly used to support the combined load which is mianly consisted of radial load. It can restrict the axial displacement of the shaft or housing in the two directions and thus can be used as a bidirectional locating bearing.
2. Application:rolling mills, gearboxes, hoisting equipment, mining machines, tunnelling machines.
3. Advantage: Double row taper 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 changes loads, such as reducers and coiling machines. The radial and axial clearance can be adjusted by changing the width of spacer between two inner rings.
4. Our double row tapered roller bearings are produced in two configurations and in several different designs:
The performance of type TDO bearing is the same as two single-two tapered roller bearings in back to back mounted.
Type TDI bearing is mainly used in roll necks with medium loads. This type of bearings have a cup spacer, and the clearance is asjustable
5. Size range: Inter diameter:150-1778mm
6. Material: GCr15/GCr15SiMn/G20Cr2Ni4A

 What is a Double Row Tapered Roller Bearing?

A Double Row Tapered Roller Bearing is a type of bearing that is designed to handle heavy radial and axial loads simultaneously. This bearing features two rows of tapered rollers arranged in a way that they converge at a single point on the axis of the bearing.
