No insulated bearings required

June 2023 Motion Control & Drives

Earthrings has developed the world’s most reliable and co-t effective bearing protection solution, tested and approved by all electric motor manufacturers in South Africa

Earthrings protects all motors up to 400 kW without the use of insulated bearings, insulated housings or any other technology. Earthrings is also the only product in its category that comes with an official 10-year guarantee. Earthrings saves you money and lasts the operating life of your motor, so no unnecessary maintenance or replacement intervals are required. Shaft voltages from variable speed drives (VSDs) are one of the biggest causes of downtime on motors powered by VSDs, but are the least identified. Shaft voltage damage is seen as ‘frosting’ or ‘fluting’ in the bearing, and also as dark, burnt, damaged grease. All electric motor manufacturers around the world advise shaft grounding as a critical and necessary protection on their electric motors.
