Choosing the Right Bearing for Your Industry

Selecting the suitable bearing for an industrial application requires the careful study of several critical factors that influence the ability of the bearing to perform and last. Other things to consider when choosing a bearing include load capacity, operating environment, speed, and maintenance requirements. Spherical roller bearings are considered robust enough to withstand extreme radial or axial loads and their applications include the steel industry or mining, while compensating for misalignment. On the other hand, industries such as aerospace or medical equipment would more often rely on angular contact ball bearings because of their high speed and high precision.

Environmental conditions are paramount in bearing selection. For any industry under severe temperature extremes, like power generation or chemical processing, operating bearings at high temperature with special lubrication would be accepted if reliable service is to be maintained. Similarly, industries thronging the corrosive environments such as food processing or marine settings would normally have need for stainless steel or coated bearings, which put up a good resistance to wear and corrosion.

An evaluation of the speed of operation must be done. In the high-speed electric motor or turbine system, those that are at the edge of the renewable energy industry have the tendency to always be designed with bearings that can run quietly at very high rotational speeds, with new lubrication solutions often aiding in heat dissipation.

Depending on your industry’s specific requirements, an optimal setting of bearing characteristics brings forth more efficiency, less downtime, and an increase in equipment life expectancy. With the aid of a trustworthy supplier like SKF, it is guaranteed that you will have the very latest bearing technology at your disposal to meet the on-the-go demands of modern industrial operations.
