Tapered Roller Bearings

Double Row Tapered Roller Bearings

Tapered roller bearings feature a cup and cone assembly. The cup is comprised of the outer ring and the cone assembly consists of inner ring, rollers, and cage. This bearing construction accommodates combined loads and provides low friction during operation. By adjusting one single row tapered roller bearing against a second tapered roller bearing and applying a preload, a rigid bearing application can be achieved.Tapered roller bearings are separable bearings. Both the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into single row, double row and four row tapered roller bearings according to the number of columns of rolling elements.
The tapered roller bearing is designed so that the apex of the tapered face on the raceway face of the cone cup intersects with a single point on the bearing centerline. Suitable for applications with heavy load and impact load.

Double taper roller bearing is mainly used to bear combined loads mainly in radial directions. It can limit the axial displacement of the shaft or housing in two directions, so it can be used as a two-way locating bearing. Double taper roller bearing has a low number of parts, high stiffness, and easy loading and unloading. For this reason, they are often used in applications where the load varies, such as reducers and winders. Radial and axial clearance can be adjusted by changing the width of the spacer between the two inner rings. Our double-row tapered roller bearings are available in two configurations and several different designs: The TDO-type bearings have the same performance as two single and double tapered roller bearings mounted back-to-back. The TDI-type bearing is mainly used for roller journals with medium loads. This type of bearing has an outer ring and adjustable clearance.

Features of Double Row Tapered Roller Bearing

The tapered roller bearings can be double-row tapered roller or taper lock bearings. It consists of two sets of tapered raceways and tapered rollers. As a result, they have a higher load-carrying capacity. In addition, these bearings have a higher stiffness. The two sets of races and rollers on the two rows are positioned in opposite directions. Therefore, they can support a higher load capacity in both methods.
