Electrically charged bearing wear and pitting test | Electrical conductive grease test

Описание: A test simulating the challenges faced with a bearing static discharge application. In this test a bearing is electrically charged, when a bearing is lubricated with a non-conductive grease static discharge is not only a safety concern but wear and pitting occurs at a much increased rate when compared with a quality synthetic electrically conductive grease.
It should be noted that some electric motors can generate internal voltages and currents that may or may not discharge through the bearing, so static electricity is not the only source of electrically induced bearing wear. This is especially true of variable frequency drive motors.

Static build up and discharge in bearings can shorten bearing functional life; the use of a quality synthetic electrically conductive bearing grease will improve the reliability and functional life of the bearing. Also, the a conductive bearing grease is often essential for rotating equipment that is operating in sensitive, ATEX (explosive) type environments. The grease featured on this video and available through Newgate Simms is a high quality, durable, electrically conductive grease that has a pedigree in ATEX environments and is also used for mechanical joints ensuring bonding to earth in applications such as underground train carriage chassis and joints ensuring a path to earth for lightning strikes.
