PRORING Split-Design – High-Capacity Shaft Grounding

Uncompromising bearing protection for high-power applications, now with a versatile split-ring architecture for seamless installation.

The PRORING Split-Design is engineered specifically for the most critical and largest motors, generators, and turbines where traditional installation is not feasible. This high-current capable system combines our proprietary conductive technology with a precision-engineered two-piece frame, allowing for world-class protection without the need to decouple the drive or disassemble the machine.

Key Technical Features:

1. Engineered for Large Frame & High Voltage Units

Specifically designed for large-frame low-voltage motors (375kW and greater), medium-voltage motors, and high-power DC machines. The PRORING Split-Design is scalable to accommodate shaft diameters exceeding 400mm, providing reliable grounding for units where induced shaft voltages and bearing currents are significantly higher.

2. High-Current Dissipation with Steered Charge Technology

Large generators and turbines often experience current surges that cause catastrophic electrical arcing in bearings. Our Steered Charge geometry, integrated into the split frame, ensures these high-current surges are "suctioned" and channeled safely to ground via the path of least inductance.

3. Zero-Downtime Installation (Split-Ring Architecture)

The precision split-ring design allows for a rapid retrofit on existing equipment. By eliminating the need to remove couplings or pulleys, the PRORING Split-Design reduces maintenance windows from days to hours, ensuring the drive is protected against EDM (Electrical Discharge Machining) with minimal operational interruption.

4. Advanced Metal Surface Integration

To ensure the split design maintains monolithic efficiency, we utilize a proprietary metal surface modification at the joining interfaces. This eliminates the contact resistance typically found in multi-part systems, ensuring that the high-conductivity fibers maintain a perfect electrical path to the housing at all times.

Application and Specifications:

Target Equipment: Large motors, generators, and turbines operated by VFDs (Variable Frequency Drives).
Contaminant Protection: Available with optional O-ring barriers to prevent ingress of debris, dirt, lubricants, or moisture that could interfere with conductive fiber contact.
Mounting Versatility: Supplied with high-grade hardware for bolt-through mounting, with optional universal brackets and stand-off kits for flexible installation on virtually any large motor frame.
Standard Compatibility: Ideal for DE (Drive End) installation to complement insulated NDE (Non-Drive End) bearings for maximum system longevity.

The PRORING Split-Design represents the pinnacle of retrofit technology—delivering the heavy-duty performance of a solid ring with the installation flexibility required by modern industrial maintenance.
