Tired of poor rotary ground consistency? Consistently having to grease and maintain a metal-on-metal rotary ground? Is fluctuating resistance causing variable consistency in your process, leading to scrapped product? If you are experiencing any of these problems associated with traditional rotary grounds, a ROTOCON rotary ground is the solution.

Suitable for all environments and applications including rotary welding, electro-plating, electro-polishing, cutting, and other high current rotating industrial applications, the ROTOCON ERG/MC & ERGT Series are designed to withstand 100% duty cycles in continuous manufacturing and production processes, without interruption or downtime. The ROTOCON’s brush-free design eliminates all issues such as maintaining brush contact and conductivity, does not require application of conductive greases, and eliminates elevated contact resistance associated with conventional brushed rotary grounds. With the ERG Series, you will achieve a more consistent ground, with zero fluctuations in resistivity, or elevated contact resistance over time and revolutions; this will lead to a better end product in rotational welding, plating, polishing, and other high current applications that require rotation. ROTOCON rotary grounds can be used interchangeably on the positive or negative (ground) of an application without any difference in performance.
