Features and Benefits of Double Row Taper Roller Bearing

Double Row Taper Roller Bearing

The main function of the various bearings is to ease the various types of motions between the two moving parts. These different types of bearings are classified based on their operations, types of motions, the direction of motion, forces applied, load capacity, etc. A roller bearing is a commonly used bearing. There are different varieties of roller bearing based on the various shapes of the roller elements.

Types of double row taper roller bearing:

The assembly of double row taper roller bearing consists of two raceways, the inner and the outer raceway. The bearings are placed between these two raceways. These bearings as the name suggests have a tapered contact angle. These double row taper roller bearings can be classified into various types based on the different parameters like the raceways. The shape of the raceways helps to define the two different versions of the bearings as:

Double-cup type: It has an assembly having two separate cups that fit into the ends one forming one dual cup.

Double-cone type: This type has the assembly of two separate cones fitting into each other and forming one dual cone.

Features and Benefits of double row taper roller bearing:

There are different features of these double row taper roller bearings that provide added benefits like:

Higher load-carrying capacity: The double row taper roller bearing has two rows of bearings of two rows of the bearing raceways that increase the load-bearing capacity. These allow carrying heavy radial as well as axial loads.

Load direction: In these beatings, the shaft can be located in both directions considering the specific axial clearance. This allows carrying heavy loads in both directions.

Lower friction: This design of the bearing in tapered form allows very little friction. The design of the roller end and the flange allow lubricant film formation that lowers the friction.

Prolonged bearing life: The reduction in friction while operation reduces the temperature while operation. The contact surface is less thus less stress at the roller edge is less. The assembly reduces the shaft deflection and sensitivity to misalignment This enhances the efficiency of the bearing and prolongs the life of the bearing.

Contact angle: The angle of contact in this double row taper roller bearing is tapered and varies between 10 and 30 degrees. The larger the contact angle, the more is the load-bearing capacity of the bearing.

Higher stiffness: The assembly of the double row taper roller bearing provides a stiff arrangement of the bearing.

Considering the different features of the double row taper roller bearing, one has to select the best bearing according to their requirements.
