About Us:

SGS^TM shaft grounding systems prevent electrically induced bearing damage on variable frequency drive motors. Having pioneered this industry, we have developed a 25 year scientific and field tested knowledge base across many industries.  This is far greater than any other competitor on the market.  Our systems were developed in the pulp and paper industry where long term reliability, performance and maintainability were required. 

SGS^TM systems have a class leading reputation for being the de facto long-term solution for controlling capacitive discharge that leads to bearing failure. Our reputation has not been built on flashy marketing or gimmicky presentations, but rather word of mouth and positive outcomes over a long period of time.  Our customer base heavily reflect those who have tried other grounding systems only to be disappointed that their intial attempts for a solution failed.  Our design philosophy always keeps in mind the end user and their needs whether it's controlling maintenance costs, decreasing the risk of production loss  or lost comfort due to a downed HVAC system.

We understand that providing a long term and cost effective solution for controlling electrical bearing damage involves more than just making brush to shaft contact.  Our elegant and robust non-drive end and drive end (split ring) shaft grounding systems ensure that the necessary target voltages are achieved and maintained for the life of the brush.  Our non-drive end systems offer the unique distinction of being the only effective grounding system that can be maintained (brush change) while the motor is in operation.   

Together,  the founders of  SGS^TM and DP&A Sales discovered in the 1980s they had a serious and costly issue with electrical bearing damage at the paper mill they worked. Out of practical necessity, they created and brought to market the first and only effective long term shaft grounding solution for controlling electrical bearing damage. We have been amazed to see the decades long attempts of others trying to create products that try to outperform SGS^TM.   Simply put, all those attempts have failed. 

If you're serious about controlling your risk for electrical bearing failure, then please give us a call or send us an e-mail and we'll discuss your particular application.  

SGS™ Product Highlights:

• Only long term shaft grounding solution on the market that is field tested and proven to eliminate electrical induced bearing damage.
• SGS™ CR and SR series shaft grounding systems have proven to run for over 10 years at 1800rpm on VFD powered motors without the need for maintenance while eliminating electrical bearing damage.  This proven performance and reliability is exclusive to SGS™ products.
• Only end of shaft application on the market which allows for class leading maintainability.  Leading competitor grounding systems have poor wear tolerances and are not inherently maintainable.  In addition, competitor grounding systems are inherently less able to control shaft voltages as the running surface is exposed to environmental contamination.  Simply put, contamination equals poorer shaft grounding capability over time.
• Highly maintainable systems that can be maintained WHILE the motor is in operation.  No other grounding system passes SGS™ stringent maintenance criteria.
• Robust, industrial grade systems that are designed to withstand harsh environments.
• System design provides a clean running surface at all times (standard on CR and CL series) while maintaining excellent brush to shaft contact to ensure a low impedance route for electrical discharge for the entire life of the brush.  This feature is unique to SGS™ shaft grounding systems and is why SGS™ products are the preferred solution for serious applications.
• All systems are designed for field installation with handheld tools and without the need for uncoupling the motor.
• To specify SGS™ products, please contact us and we will provide you with the necessary documentation to help you with this process.
