Updated: Apr 29, 2020

Why to work with RKB

RKB bearings are widely used in this type of application. One of the most appreciated characteristics is the reliability of our bearings, that permitted many customers to benefit of a sensible reduction of unexpected equipment failure. In fact, the first quality bearing steel used, the optimized internal bearing geometry, the optimal rolling elements and raceways profiling and much more, lead to an excellent distribution of the external loads inside the bearing and to reduce the negative effects induced by the level of vibrations proper of this kind of application.

All these technologies, corroborated by the constant presence of RKB on-field technical personnel, are maximizing the overall bearing service life, leading to an increased reliability of all the coal pulverizer.

Application description

Nowadays, the ever-growing demand of alternative energy leads also to an important upgrade of traditional energy. In a coal power plants, a coal pulverizer assumes a paramount importance in order to increase boiler efficiency by providing pulverized coal with a specific granulometry. In a coal pulverizer, rolling bearings are fundamental.

RKB reached an enviable experience, competence and reliability in this specific application, obtaining successful and countless excellent results in providing bearings for the most critical coal pulverizer assemblies, like grinding rollers and grinding table speed reducers.
