Self lubricating carbon graphite bearings & carbon bushings are ideal for applications where normal lubricants can not be used. Even high temperature applications are not a problem for carbon graphite. We have a wide selection of grades and sizes in stock and have the ability to manufacture custom parts quickly. With our CNC equipment we manufacture a wide variety of shapes and routinely hold tolerances of 0.0005” (0.013 mm).
Advantages of Carbon Graphite Bearings & Bushings
- Self lubricating
- Low coefficient of friction
- Non galling
- Resistance to chemicals, corrosion, and oxidation
- Compatible with food & pharmaceuticals
- Low density
- Low coefficient of thermal expansion
- Excellent thermal shock
- Good thermal conductivity
- Good mechanical strength
- High temperature resistance
Typical Applications for a Carbon Bearing or Bushing
- Temperatures above 400° F
- Corrosive environments
- Areas where conventional lubricants could contaminate product
- Location is inaccessible for lubrication
- Dusty environments
- Chemical pumps
- Food processing pumps
- Process pumps in refineries
- Cold and hot water pumps
- Cryogenic applications
