With insulation properties integrated into the bearing, insulated bearings can improve reliability and increase machine uptime by virtually eliminating the problem of electrical corrosion.
The aluminum oxide coating has a minimum resistance of 200MΩ and can withstand voltages up to 3000 V DC.
Plasma spray coatings are generally hygroscopic and therefore susceptible to condensation causing penetration. To prevent this effect, insulating bearings are treated with a unique sealant.
