An Overview About Single Row Angular Contact Ball Bearings
April 22, 2020Different industrial applications are using ball bearings as part of their specific equipment and machines. Ball bearings are intended to connect two machine members as their movement corresponds to one another. They intend to minimise the frictional resistance to motion so that the specific equipment or machine can work smoothly.
Aside from reducing friction, ball bearings are also used in supporting radial and axial loads. Their supporting role is done through the help of the balls that can be found inside their races. As one of their races rotates, this movement causes the balls to rotate as well. The other race, on the other hand, will remain stationary since it is not attached to the rotating assembly, unlike the rotating race.
One type of ball bearings is single row angular contact ball bearings.
Definition and Parts
These bearings have single raceway grooves in the inner and outer rings that relatively offset. They also have an inseparable upper and a lower shoulder. They can only support axial loads in one direction, which makes their intended use limited to select applications. This type of bearing is usually adjusted against a second bearing.
Benefits and Features
Single row angular contact ball bearings have numerous benefits and features. One of the benefits of using this type of bearings is they have a high load-carrying capacity. Their lower shoulder allows them to incorporate a large number of balls in the bearing, which gives them a high load-carrying capacity.
Another benefit of using these ball bearings is that they have great running properties. Operations like rapid accelerations and decelerations are possible thanks to their overall properties and components. Lastly, single row angular contact ball bearings can be easily mounted to universally matching bearings. These bearings do not need any adjustments for correct internal clearance or preload.
Temperature Limits
The operating temperature for single row angular contact ball bearings is limited by the dimensional stability of the bearing rings and balls, cage, seals, and lubricant.
The bearings rings and balls are heat stabilized up to at least 150 °C. Despite this temperature, cages made from steel, brass, or polyether ether ketone (PEEK) can still work well with bearing rings and. On the other hand, the operating temperature for nitrile rubber seals is -40 to +100 °C. While these seals can still tolerate temperatures up to 120 °C, they can only work for a brief period. The temperature peaks are normally at the seal lip.
Several types of greases can be used in this type of bearings. GXN, GJN, MT33, WT, and other types of greases can work well in temperatures ranging from 50 to 150 °C.
Uses and Applications
Single row angular contact ball bearings are best recommended in industrial pumps, compressors, material handling, and electric motors. Pumps that extract water, oil, or aggressive fluids have components that can utilize the wonders of this type of bearings. Moreover, these bearings help compressors in compressing refrigerant vapour, transporting gases across process plants, supplying high-pressure air to power air tools, and many more.
Material handling components and equipment like cranes, conveyors, elevators, and escalators utilise the benefits of single row angular contact ball bearings. These bearings can help these tools in boosting productivity and reliability. Lastly, electric motors require high-quality bearings so that they can be used in rotating equipment and machinery.
