ROTOCON Through-Hole Rotary Grounds | ERGT Series

• Provides stable and consistent current delivery
• Does not require grease, adjustment, or maintenance
• Unaffected by rotation or total number of revolutions

Meridian Laboratory’s series of through-hole / through-bore rotary grounds are designed with a hole in the center to mount over or onto a shaft, or allow media to pass through the center. They provide a low resistance rotating ground path for electrical current. ROTOCON though-hole rotary grounds provide stable and consistent current delivery with no changes or fluctuation in amperage over time regardless of orientation, total revolutions, or instantaneous speed.

ROTOCON through-hole rotary grounds are offered with a center hole up to 2.50” (63.5mm) in diameter, allowing for a shaft or media such as welding gas, plating solution, and other fluids/gasses to pass through the center.

ROTOCON through-hole rotary grounds are widely used in rotary welding cells, rotary plating processes, and other high current applications which require a consistent rotary ground connection. While called a rotary ground, they can be used for either the power (positive) or the return (ground) circuit without any change in performance or longevity.

ROTOCON through-hole rotary grounds are offered in a variety of amperage ratings and hole diameters to meet your requirements. Additionally, Meridian Laboratory can design and deliver custom rotary grounds to meet your exact specifications in a cost and time efficient manner.
