Generator Bearings: Bearing with Glass-Fiber Reinforced Plastic Coating Provides High Insulation Protection

Septemebr 24 2012

With a newly developed glass-fiber reinforced plastic coating for generator bearings, Schaeffler is now providing an effective but economic alternative to the conventional coating systems used for bearings and to the ceramic rolling elements used in hybrid bearings. The glass fibers, which are soaked in epoxy resin, are wound onto the outer ring of the bearing, dried in a furnace and subsequently ground. This produces a highly efficient and effective insulating layer on the bearing, which is approximately ten times as thick as conventional aluminum oxide coatings. In terms of load ratings and dimensions however, the bearing does not differ from conventional solutions. As a result, the wound bearing also lends itself to retrofitting in existing installations.

For large bearings in particular, such as those used in wind turbines, the bearing with a glass-fiber reinforced plastic coating constitutes an alternative to bearings with ceramic rolling elements due to the cost advantages involved. In contrast to bearings coated using traditional systems, glass-fiber winding makes a convincing case by means of its significantly increased layer thickness and the effective protection it provides against passage of electric current of up to 20,000 volts.
