Shaft Grounding Device

Shaft Grounding Device

Product Introduction:

It is used to monitor the grounding condition of the device. The instrument box has two working states:grounding and measuring. It should be placed in the grounding state during transportation and daily operation, and it can only be changed to the measuring state when the grounding condition of the shafting needs to be checked. The monitoring instrument can be a pointer meter or an electronic instrument box with high charged level alarm.

The grounding assembly is suitable for grounding marine propellers with different diameters. Through the brush of this device, the shafting can be ensured to have good grounding performance at any time, which can reduce the corrosion of the propeller and prolong the service life of the propeller shaft and bearing.

Key Features:

1.Low Electrical Resistance

Provides a continuous, stable contact resistance below 0.1 Ω, ensuring reliable current diversion.

2.High-Quality Micro-Fiber Technology

Utilizes conductive micro-fibers or silver-graphite brushes that maintain consistent contact with the rotating shaft surface, even under vibration or minor shaft runout.

3.Self-Adjusting Design

Spring-loaded brush mechanism automatically compensates for brush wear, maintaining optimal contact pressure over extended service intervals.

4.Corrosion-Resistant Construction

Housing made of marine-grade materials (bronze, stainless steel, or coated aluminum) to withstand harsh saltwater environments.

5.Easy Retrofit Installation

Split-ring or clamp-on design allows installation without removing the shaft or major disassembly of machinery.

6.Monitoring Capability (Optional)

Integrated wear indicator or remote monitoring module provides real-time feedback on grounding performance and brush condition.

Typical Applications:

*Main propulsion shafting systems

*Shaft generators (PTO / PTI)

*VFD-driven bow thrusters and azipods

*Diesel generator sets

*Electric motors for pumps, fans, compressors

*Stern tube and intermediate bearings
