Shaft Grounding Rings


SixthElementAustralia P/L are proud to announce the exclusive distributorship for Australia, New Zealand and Indonesia for the technically differentiated EARTHRING range of shaft grounding products, designed to prevent damaging shaft voltages caused by VVVF (Variable Voltage Variable Frequency) drive systems, which leads to motor bearing failures.

Bearing damage caused by Shaft Voltages

EARTHRING Product Range

Innovative Contamination Protection

Innovative design, allows contaminant dispersal during operation, ensuring maximum shaft contact is achieved, assisting in the suppression of damaging shaft voltages

Electric motor bearings are expected to last on average 50 000 hours, but bearings on VSD driven motor applications are only lasting on average 17 800 hours. Electric motors that have Earthrings attached are proven to get as much as 300 to 400% more life-span than motors without Earthrings.


Standard LV (Low Voltage) products in solid and split designs are available for both IEC and NEMA shaft sizes. Solid units can be press fitted as required.

High Voltage, High Current and bespoke designs can be accommodated by completing our online contact form via the button below
