no insulated bearings required web(No INSULATED BEARINGS Required)


Yes , its true after 10 years of testing , without one failure all our new LV Earthrings require No insulated bearings or housings at all (for all low Voltage motors up to 500Hp) , and can be used as a stand-alone product, saving you money and labour .

Actually we have tested this for so long and at so many Blue Chip customers over the last decade that we also back it up with the Largest motor Guarantee in the industry.


The only 500 Hp Guarantee in the Industry!

“If you have the best product , you should put your money where your mouth is , and back it up with the Best Guarantees, that’s what we are doing !” – Troy Timm Earthrings (pty) Ltd Director.

Superior Quality and the highest “Current carrying capacity” of our Earthrings allows for the best and largest Guarantee in the industry today.

Due to the highest quality materials and Proprietary designed Microfibers we out perform every other product on the market.
Our 500HP Performance Guarantee is unmatched and it covers all low voltage motors up to 500HP ( 375kw).



Reducing Downtime, Increasing Motor Life!

Earthrings are used to protect bearings from the negative side effects of High Shaft Voltages, that are present from modern day variable speed drives (VSD’s), for both AC and DC motors, as well as eddy currents from large AC motors. Research has shown an increase of bearing life by up to 400% with the use of Earthrings.

Eddy Currents Damaging Bearing Grease - Increasing Service Intervals.
The darkened finish was caused by electric currents.

The “Picket Fence” pattern is due to shaft voltages.

Get the Correct Life-Span out of your Electric Motor

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
