NKE manufactures bearings with ceramic rolling elements. Technologies are advancing rapidly and bearings must meet more sophisticated and varied requirements under increasingly demanding operating conditions. In response to these special needs, NKE Austria and FERSA have committed to the development and manufacturing of hybrid bearings. Hybrid bearings can be used in new applications where conventional steel bearings have not been beneficial. For example, bearings with ceramic rolling elements are especially designed for applications where high-grade electrical insulation is necessary and/or high speeds occur. Furthermore, NKE premium hybrid bearings possess excellent performance characteristics, like extended service life and reduced friction. NKE spherical roller bearings are used to support high radial loads and compensate for misalignment of the bearing positions and/or increased shaft bending. This type of bearing is suited for applications with high loads and difficult operating conditions. NKE spherical roller bearings were designed to withstand such conditions in demanding operational environments. In order to achieve maximum strength and longevity high quality bearing steel is used. An optimized inner design with an increased number of rollers allows for higher load capacities of our products. The inner design is optimized for challenging operating conditions, reduces wear and heat and therefore the usage of lubricants. This results in less downtime and reduced effort and finally to a reduction of costs. NKE provides bearings with oxide ceramic insulating layers on the bearing ring. Applied with plasma technology, the insulation has a guaranteed breakdown resistance of at least 1,000 V AC or DC.
