NKE electrically insulated rolling bearings reliably prevent current discharge. Three versions are available. Bearings with oxide ceramic insulating layers - Applied with plasma technology, the insulation has a guaranteed dielectric strength of at least 1000 V ac or dc.
SQ77: Insulation on the outer ring.
SQ77E: Insulation on the inner ring.
SQ77B (hybrid bearing): Rolling bearing with oxide ceramic rolling elements. Resistance of insulation theoretically indefinte.
The advantages of NKE electrically insulated bearings are:
- Higher operational reliability through optimum protection against electrical corrosion
More economic than, for example, insulation on housings or shafts.
- Interchangeable: Same key dimensions and technical properties as conventional bearings
Coating resistant to damage if correctly handled
NKE manufactures electrically insulated cylindrical roller and deep groove ball bearings in standard sizes with outer ring diameter between 80mm and 400mm. Other bearing types and special sizes are available upon request.
