OUR PRODUCT RANGES

Proven Solutions for Every Application

Earthrings shaft-grounding solutions are designed to protect electric motor bearings against damaging electrical currents that can cause premature bearing wear and unexpected motor failure. From adjustable and fixed-size grounding rings to specialist protection systems, the Earthrings product range supports a variety of motor sizes, operating conditions and industrial applications.

CORE PRODUCT RANGES

LV-ARC

Adjustable | Low Voltage

The LV-ARC range offers adjustable shaft-grounding protection for low-voltage electric motors. Designed to accommodate multiple shaft diameters, these rings simplify product selection, installation and inventory management. Their conductive fibre technology helps divert unwanted electrical currents away from motor bearings, reducing the risk of electrical discharge damage and premature bearing failure.

HV-ARC

Adjustable | Heavy-Duty Motors

Designed for larger, more demanding industrial motor applications, the HV-ARC range combines adjustable shaft-grounding capability with robust construction. Its conductive fibre system provides a low-resistance path for shaft currents, helping protect bearings in heavy-duty operating environments. The adjustable design offers flexibility across compatible shaft sizes.

LV-CLASSIC-NEMA

Fixed-Size | NEMA Motors

The LV-Classic-NEMA range provides fixed-size shaft-grounding solutions for low-voltage electric motors built to NEMA frame standards. Commonly used in North American industrial environments, these rings help protect motor bearings against damaging electrical discharge currents. Their established design makes them suitable for installations requiring specific shaft dimensions and mounting arrangements.

LV-CLASSIC-IEC

Fixed-Size | IEC Motors

The LV-Classic-IEC range is designed for low-voltage electric motors manufactured to IEC frame standards used internationally. These fixed-size grounding rings provide a conductive path for harmful shaft currents, helping reduce electrical bearing damage and extend operational reliability. The range offers solutions for compatible industrial motors across a variety of applications.

ADDITIONAL RANGES AND SPECIALIST SOLUTIONS

HV CLASSIC

Custom-Manufactured | High Voltage

The HV Classic range provides custom-engineered shaft-grounding solutions for large industrial motors where standard ring sizes or mounting arrangements may not be suitable. Developed for demanding applications, including motors above 400 kW or 600 V as described by the manufacturer, these products can be tailored to specific installation requirements. They help provide effective bearing protection for critical industrial equipment.

SEAL-X / ULTRA

Specialist Protection | Contaminated Environments

Seal-X and Ultra are specialist shaft-grounding concepts developed for operating conditions where exposure to grease, oil and contaminants may affect conventional conductive fibres. The described PTFE-based sealing approach helps protect the grounding elements from contamination, supporting reliable performance in challenging industrial environments.

e-EARTHRINGS

Electronic Shaft Grounding | Monitoring Technology

e-Earthrings represents an advanced approach to shaft grounding by combining bearing protection with electronic monitoring capabilities. The manufacturer describes features such as real-time shaft-voltage monitoring, warning indicators and replaceable cartridges. The concept is intended to provide maintenance teams with additional visibility into shaft electrical conditions.
