Rolling bearings have revolutionized the industry by their varied uses in machines and other applications. They are so indispensable that they can help rotate different machine elements at high speeds. These bearings come in various types to help solve critical problems.
Offering high precision at high rotational speeds and low friction, rolling bearings are predominantly used in various applications owing to their high versatility and flexibility. They are cost-effective components and are standardized to facilitate easy exchanging during the operation of machines. You can therefore find them in any type of equipment or machinery to support and guide the rotational movement of machine elements, such as axles and wheels, with minimal noise, friction, and wear.
General Classification of Rolling Bearings
Rolling bearings are categorized based on the roller types and they are:
- Ball bearings
- Roller bearings
The way these bearings make contact with the ring raceways distinguish them. When the ball rolling element makes point contact, the roller rolling element makes line contact. In the former, the small contact point, which is an elliptical area, provides reduced friction to help ball bearings handle high speeds; however, it limits their capacity to carry heavy loads.
In the latter, the contact line becomes a rectangular line, with the increasing load acting on the bearing. The roller bearings however help handle heavier loads at lower speeds than those handled by ball bearings.
Application of Ball Bearing Rollers in Industry
When it comes to the use of bearings, they are the most sought-after components in any industrial sectors. Unlike ball bearings, ball bearing rollers are widely used owing to their higher radial load capacity. For this reasons, they are predominantly used in heavy applications in various industries. You can find the latest versions of automobile bearings, such as needle roller thrust bearings, tapered roller thrust bearings and cylindrical roller thrust bearings used in various parts of the vehicles in automobile engineering.
The other types of thrust roller bearings, such as a spherical roller thrust bearing and their variants are largely used in sectors like power generation, construction, wind turbines, mining, rolling mills, agriculture, aerospace, gear-reduction units, and robotics. With several research studies conducted on the viability and flexibility of roller bearings, you can find these bearings available in various designs, class clearance and series. The sizes and dimensions are standardized to facilitate easy interchangeability.
Further technological developments have led to the introduction of smart bearings, which come with sensor units. These bearings are built to survive extreme conditions and handle critical applications. They are designed to have a self-lubricating system, where the bearings get regular lubrication through the bores and holes while in operation.
The information given above helps choose appropriate ball bearing rollersfor various applications. With several types, features and uses, you can limit your choices and find the right one to meet your requirement.
