Type of Customized Carbon Graphite Blanks
Our carbon graphite blanks can be custom-manufactured to your specific requirements. We develop our own proprietary carbon grades, so we will work closely with you to develop the right blanks for your customized products. The type of blank that you require depends on your specific application. We provide the following options:
Carbon Rod Blanks
Reliable stock for machining bushings, bearings, seal rings, vanes, and current-transfer parts. Available saw-cut for your secondary ops or ground to tighter tolerance to speed assembly and reduce finishing.
Common uses:
- Bearings & bushings
- Mechanical seal faces
- Pump/compressor vanes
- Electrical/brush components
What to specify: OD/ID/length, finish (saw-cut vs ground), tolerance range, target environment, and grade preference if known.
Carbon Plate / Block Blanks
Flat stock and thick blocks for rings, segments, plates, fixtures, and large components. Supplied cut-to-size and optionally ground for thickness/flatness control.
Common uses:
- Mechanical seal plates
- Wear plates
- Furnace/kiln fixtures
- Machining billets
What to specify: L×W×T (or block dims), flatness/parallelism needs, finish, and service conditions.
Carbon Slug Blanks
Short lengths and custom slugs for small turned/milled parts where yield and spindle time matter. Ideal when you need repeatability with minimal prep.
What to specify: Diameter/length, length tolerance, chamfer/deburr needs, finish, and operating environment.
Environments, Conditions and Applications for Industrial Carbon Blanks
Electrical Transmission
Our proprietary grades have unique performance characteristics particularly suited for dynamic electrical transmission applications.
Dry Running / Self Lubricating
Due to their inherent self-lubrication properties and dry running capabilities, our products are capable of running without lubricants.
High Temperatures
Our high temperature grades are developed specifically to withstand extremely high temperatures while maintaining high strength.
Low Temperatures
For environments involving extremely low temperatures, our products will withstand these temperatures while maintaining their key characteristics
Corrosive & Harsh Environments
Our grades are able to be used in a variety of corrosive and harsh environments while resisting decomposition or degradation of the materials.
High Friction
Resists wear and reduces friction as it is chemically inert, oxidation-resistant and self-lubricating.
Sanitary Environments
When an application requires sanitary conditions, e.g., food & beverage, medical, our products are the ideal solution.
Submerged / Marine Environments
We have specific grades that are able to operate in both freshwater and saltwater.
High Altitude
When our products will be operating at high altitudes, we have developed specific grades for these instances.

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 …
