Metric series Double-row tapered roller bearings

Double row tapered roller bearings are used to carry combined radial and axial loads mainly consisting of radial load. They can limit axial displacement in two direction of the shafts (or shells) and can therefore be used as bidirectional axial positioning bearings.
The performance of double row tapered roller bearings (type TDO) is similar to that of two single row tapered roller bearings installed back to back, but the double row tapered roller bearings have fewer parts, are easier to install and disassemble and have better rigidity. Therefore, they are often used for alternating load carrying conditions, such as reducer, coiling machine and so on.

Product introduction
Double row tapered roller bearings are used to carry combined radial and axial loads mainly consisting of radial load. They can limit axial displacement in two direction of the shafts (or shells) and can therefore be used as bidirectional axial positioning bearings.
The performance of double row tapered roller bearings (type TDO) is similar to that of two single row tapered roller bearings installed back to back, but the double row tapered roller bearings have fewer parts, are easier to install and disassemble and have better rigidity. Therefore, they are often used for alternating load carrying conditions, such as reducer, coiling machine and so on.
The performance of the double row tapered roller bearings (type TDI) is similar to that of two single row tapered roller bearings installed face to face. Compared to double row tapered roller bearings (type TDO), double row tapered roller bearings (type TDI) have smaller installing space but less rigidity. Most of them are used as positioning end bearings carrying medium load, such as roll bearing positioning end, reducer and so on.
There is a spacer ring between the two inner rings of an double row tapered roller bearing (type TDO) and a spacer ring between the two outer rings of an double row tapered roller bearing (type TDI). The radial and axial clearance of the bearing can be adjusted by changing the thickness of the spacer ring.
