Carbon Graphite Electrical Contacts That Reduce Arcing, Wear, and Downtime
In electrical systems, contacts must manage arcing and wear while maintaining reliable current transfer to avoid unplanned downtime. Performance depends on matching contact materials to operating conditions and electrical demands across the service life of the application.
Each of our ARC Electrical Contacts can be custom-manufactured to your specific requirements. We develop our own proprietary carbon grades and manufacture each product in-house, so we will work closely with you to create a product that is suited to your application.

Carbon Graphite Mechanical Seal Types
Rotating equipment often requires a dynamic mechanical seal to create a seal between a rotating shaft and a stationary body and prevent the escape of process fluid(s) including liquid and/or gas. They can also be used in mixer seals to prevent fugitive ambient particulates from entering a contained vessel being being mixed such as a pharmaceutical reaction…
Why Bearings Fail and How to Prevent It
All bearings have a fixed life expectancy. Some are replaced because of normal wear or spalling, and others need replacing because of premature wear or failure. An unexpected failure can cause damage to equipment, downtime, costly replacement, and possibly even injury. And, even before they fail, the premature wear is likely to have effects on performance …
Carbon Graphite Conductivity & Expansion
When deciding on the materials for carbon graphite components or parts, it all starts with a thorough review of the application which includes the components’ form/function/fit and property identifying the “must haves” and the “nice to haves” and melding these with a design for manufacturability. There are three important physical characteristics …
