OVERVIEW

Innovative, Maintenance-Free High Current Electrical Rotary Grounds

  • PROVIDES STABLE AND CONSISTENT CURRENT
  • DOES NOT REQUIRE GREASE, ADJUSTMENT, OR MAINTENANCE
  • UNAFFECTED BY TOTAL NUMBER OF REVOLUTIONS OR ROTATION
  • STANDARD MODELS AND CUSTOM SOLUTIONS
  • NON-MERCURY ROTARY GROUND (RoHS) MODELS AVAILABLE

Meridian Laboratory’s ROTOCON ERG Series of brushless rotary grounds are designed to mount at the end of a workpiece and provide a low resistance rotating ground path. ROTOCON brushless 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.

All ROTOCON brushless rotating grounds are environmentally sealed and use robust and corrosion resistant materials that ensure a long service life without the maintenance and grease required by conventional, metal-on-metal rotary ground manufacturers such as Tweco (ESAB) Roto-Ground, Lenco, Sumner, and others.

ROTOCON brushless rotating grounds are widely used in rotary welding cells, rotary plating processes, and other high current applications which require a rotary ground. Although referred to as a rotary ground, these can be used for both power (positive) and return (ground) circuits with no impact on performance or lifespan.

ROTOCON brushless electrical rotary grounds are also offered in non-mercury, RoHS versions. Additionally, Meridian Laboratory can design and deliver Custom ROTOCON Rotary Grounds to meet your exact specifications in a cost and time efficient manner.

Advantages

Why Choose ROTOCON Brushless Rotary Grounds?

CONSISTENT CURRENT PROVIDING BETTER RESULTS

ROTOCON brushless rotary grounds provide a low-resistance connection between stationary and rotating elements of an application. Their superior design ensures current delivery does not fluctuate over time or under rotation, something which metal-on-metal contacts cannot achieve. This ensures better process consistency during high current applications.

  • NO METAL-ON-METAL CONTACT
  • < 0.03 MILLIOHM RESISTANCE, STATIONARY OR ROTATING
  • DEPENDABLE CURRENT DELIVERY WHILE STATIONARY, INDEXING, AND ROTATING
  • REDUCED DEFECT RATE FROM STABLE CURRENT WITHOUT FLUCTUATION
  • 110 GRADE COPPER ENSURES OPTIMAL ELECTRICAL CONTACT FOR MAXIMUM PERFORMANCE

ROTARY GROUNDS WITHOUT MAINTENANCE

ROTOCON brushless rotary grounds do not require maintenance of any kind. They deliver unparalleled longevity and reliability, regardless of orientation or duty cycle. They provide a fast return on investment from the savings gained from reduced process downtime and replacement of conventional rotary grounds.

  • DO NOT REQUIRE GREASE, ADJUSTMENT, CLEANING, OR BRUSH REPLACEMENT
  • FREQUENTLY SURPASS 500 MILLION TOTAL REVOLUTIONS
  • MAXIMIZES ROI FROM REDUCED DOWNTIME, SCRAP, AND REPLACEMENT ROTARY GROUND SAVINGS

ROTARY GROUNDS DESIGNED FOR MANUFACTURING AND HARSH ENVIRONMENTS

ROTOCON rotary grounds are designed to be used in industrial manufacturing applications. They are made from durable materials that withstand the welding, plating, and cutting environments they are used within. This makes ROTOCON rotary grounds the ideal choice for semi or fully automated processes that demand long term consistency and reliability.

  • ROTOCON ROTARY GROUNDS FEATURE CORROSION RESISTANT 304 SS AND HIGH CONDUCTIVITY 110 COPPER
  • ROTARY GROUNDS ARE ENVIRONMENTALLY SEALED FROM DUST AND LIQUIDS*
  • DESIGNED TO SUPPORT CABLE AND CONDUCTOR LOADS**

APPLICATIONS & USES

Common Uses for Rotary Grounds

ROTARY WELDING

ROTOCON rotary welding grounds are used in rotary welding applications which rotate the workpiece. This includes pipe, tube, and metal structure manufacturing processes. They eliminate tangled cables and provide consistent current without blow through or poor penetration.

ROTARY PLATING & DEPOSITION

ROTOCON rotary grounds are frequently used in rotational plating operations which demand stable current to ensure consistency throughout the entire process. They are sealed and built with corrosion resistant materials to withstand the harsh environments.

ROTARY CUTTING

ROTOCON rotary grounds are commonly used for rotary cutting applications and provide stable current flow for plasma cutting in fully or semi-automated applications. They provide a maintenance-free rotary ground to ensure maximum efficiency without downtime.
