The MEGAOHM™ insulated bearings range blocks inverter‑induced currents that cause fluting and early grease aging in motors.
Electrical resistance classes, coating thickness and breakdown voltage are tied to typical drive voltages and switching frequencies.
Selection notes explain when to insulate inner vs. outer ring and when hybrid bearings are advantageous.
Mounting guidelines preserve insulation integrity and verify resistance after assembly.
