ROTOCON ERG-800 Model Specifications
| » RoHS / CE Compliant versions available | » 100% maintenance-free and arc-free design for uninterruptible machine output and usage |
| » Five robust mounting options, to meet the most demanding applications | » Frequently surpass 500 million revolutions without demonstrating a change in electrical resistance or performance |
The high-current ERG Series by Meridian Laboratory provides the perfect ground for rotational welding, plating, polishing, and other high-current applications that require rotation. The flexible new design offers a number of robust options and mounting variations to meet your exact specifications.
Contrary to conventional brushed rotary grounds, Meridian Laboratory’s ERG Series are arc-free, do not have internal friction, and do not require greasing or any type of maintenance. All ROTOCON rotary grounds are built environmentally sealed, and with 304SS corrosion proof housings to ensure a long service life, even in the most challenging manufacturing environments and chemical exposure.
ERG-800s are also available in RoHS / CE Compliant versions.
