Bearing Gard Isolator with electrical earthing
Bearing Gard isolators with AEGIS® earthing ring technology offer exceptional reliability and extended lifespan for electric motors operated by Variable Frequency Drives (VFDs).
This advanced technology addresses a significant issue with the increasing use of VFDs, which often results in electrical earthing through bearings, leading to premature motor failure.
Bearing Gard is specifically engineered to prevent such failures by mitigating electrical fluting and contamination ingress. Suitable for a wide range of applications, Bearing Gard ensures comprehensive protection for motors across various equipment types, including pumps, compressors, turbines, mixers, reactors, centrifuges, blowers, rotary joints, blenders, and dryers.
