More energy efficiency through optimization

On the road to greater energy efficiency, market and technology leaders are increasingly looking to optimize their products in terms of friction and wear. There is certainly potential for improvement – for example, in the production of electric motors and fans, in gearbox construction and conveyor technology.

The energy efficiency or smooth running of rolling bearings depends on the internal geometry of the bearing, the roughness of the rolling element raceways, the seal and the lubricating grease. This can be clearly explained using the example of the lubricant: It reduces metallic contact between the rolling elements and contact surfaces, reduces friction and wear, and thus increases the service life of a bearing. It also influences the efficiency and thus the energy efficiency. So for extra smooth running, users should opt for a particularly smooth-running grease or oil, a higher C3 bearing clearance and a reduced grease quantity. A non-abrasive seal prevents moisture or dirt from destroying the bearing and allowing shear material to escape. "Anyone who needs rolling bearings for the greatest possible energy efficiency should contact our application consulting service," says Klaus Findling, managing director of Findling Wälzlager. "The configuration options are almost unmanageable when you consider just the more than 3,000 different lubricants available on the market for rolling bearings."

Even for small batch sizes, Findling has an already optimized "out-of-the-box" solution ready in its full range. The Karlsruhe-based company has developed the eXtreme series for particularly demanding operating conditions from a tribological point of view. In order to achieve the longest possible service life and energy efficiency at maximum performance, different special lubrications and seal variants from the manufacturer-independent ABEG portfolio are used. Common to all series is a significantly longer service life than available standard solutions in extreme use.
