Smooth running of rolling bearings
More energy efficiency thanks to the optimum bearing
On the way to greater energy efficiency, market and technology leaders are increasingly concerned with optimizing 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 gear manufacturing and in 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 the metallic contact of the rolling elements and contact surfaces, reduces friction and wear and therefore increases the service life of a bearing. It also influences the efficiency and therefore the energy efficiency. For particularly smooth running, users should therefore opt for a particularly smooth-running grease or oil, a higher internal clearance C3 and a reduced grease quantity. A non-abrasive seal prevents moisture or dirt from destroying the bearing and lubricant from escaping. "Anyone who needs rolling bearings for maximum energy efficiency should contact our application consultants," says Klaus Findling, Managing Director of Findling Wälzlager. "The configuration options are almost unmanageable when you consider the more than 3,000 different lubricants available on the market for rolling bearings alone."
Findling also has an already optimized "out-of-the-box" solution for small batch sizes in its full range. The Karlsruhe-based company has developed the eXtreme series for particularly demanding operating conditions with tribological aspects in mind. In order to achieve the longest possible service life and energy efficiency at maximum performance, various special greases and seal variants from the cross-manufacturer ABEG portfolio are used. What all series have in common is a significantly longer service life than available standard solutions in extreme applications.
