Description
Features & Benefits
Bearing characteristics 1. Prevent electrical corrosion By integrating insulation performance into bearings, insulated bearings can eliminate electrical corrosion issues, improve reliability, and extend machine normal operating time. 2. High resistance Can withstand DC voltage up to 3000V 3. Continuous electrical performance Plasma spraying usually has hygroscopicity, so condensed water can easily penetrate the coating. To prevent this impact, insulated bearings are treated with a unique sealing agent.
