Electrically conductive grease-Bearing electrical resistance test

Any rotating component support by ball bearings is essentially isolated from the rest of the device, in part due to the lubricant in the bearing raceway. Static electricity can build up and discharge/arc across the bearing, damaging the rolling elements and accelerating wear. The discharge of static across a bearing can be hazardous, especially if the device is operating in potentially explosive or ATEX environments. Electrically conductive bearing grease can help reduce or eliminate the risk.

The test video above is intended to introduce the viewer to our three core electrically conductive greases by way of an indicative test, showing the difference in electrical resistance when a bearing is testing with conductive and non-conductive/plain grease.

To find the right electrically conductive grease for your application, take a look at the conductive grease range overview article.
