What Makes a Double Row Taper Roller Bearing Unique in Industrial Applications?

Double Row Taper Roller Bearing

Where a high degree of rigidity, as well as handling of heavy axial and radial loads in two directions, is required, a double-row tapered roller bearing is used. Its use is highly preferred in applications that support vibrations, speed, load, temperature and contamination conditions. The customized bearing design makes it suitable for any applications that ask forfunctioning under the conditions above-mentioned above.The rollers, as well as inner and outer ring washers, are tapered to accommodate both the acting loads concurrently.

With the projection lines of the ring raceways intersecting at a common point on the bearing axis to facilitate a smooth rolling action, with low frictional moments. A tapered roller bearing consists of a cup and cone assembly, with both having an outer ring and rollers respectively and an inner ring and a cage.

Where a single-row tapered roller bearing is used, adding an additional row of rollers will help increase its stiffness. The other variations in the tapered roller bearing designs are a double row taper roller bearing and four-row taper roller bearing. The double-row tapered bearing is majorly used in machine tools, rolling mills and automobile industry.

Various Features and Advantages of a Double-Row Tapered Bearings

The bearing takes much significance in having a second-row of rollers to help accommodate both axial and radial loads. Here are some inherent features of a double row taper roller bearing.

Capable of Carrying Heavy Loads: Supporting both acting radial and axial loads, a double-row taper roller bearing design has a contact angle between 10 and 30 degrees, which increases due to the larger ‘e’value, resulting in the increase in the axial load carrying capability.

High Rigidity: You can find a relatively stiff bearing arrangement in this type of bearing.

Handle Axial Loads in Either Directions: With the shaft located in both directions, a double row tapered roller bearing has a preload or specific axial clearance.

Reduced Friction: The surface finish on the flange, as well as the optimized design of a roller end allows the promotion of a lubricant film, which helps minimize friction. With this, the flange wear and frictional heat is also reduced. The bearing further maintains the preload maintenance and performs at low noise levels.

Long Service Life: The logarithmic profile of the rollers and crowned raceways help distribute the loads effectively along the contact surface and reduce the chances of shaft displacement and misalignment.

Get to Know Some Uses of Double Row Taper Roller Bearings

The bearing is largely used in several sophisticated applications such as rolling mills, machine tools, gear boxes, printing equipment, and so on.In some applications, it is used in back-to-back pairs to manage axial loads in either direction concurrently.
