graphite bearings

 Deeco Graphited Bearings — Ideal for Extremes!

Ideal problem solvers for:

High Heat

Where conventional lubricants would carbonize such as in furnaces, dryers, ovens, kilns, dust collectors, hot conveyors and louvers.

Extreme Cold...

In cryogenics.

Dry Environment...

Where contamination would be undesirable as in textile, food, drug, pollution control and printing machinery.

Wet Applicalions…

Full spectrum from high humidity to total submersion - in pumps, meters, textile finishing, chemical processing and plating equipment.

Inaccessible Locations…

Where lubrication is a problem. Graphite is self-lubricating.

 SeIf-Lubricating Systems ...without OIL!

For extremes in operating conditions, graphite outperforms oil as the bearing lubricating medium. DEECO’s graphiting capability can solve virtually any high or low temperature bearing problem...as well as applications in other hostile environments.

DEECO Graphited Bearings provide a mechanical lubrication system with graphite. They are oilless and selflubricating...designed for long life without downtime.

Quality Is Our Niche

A quality graphite bearing starts with quality bronze. Our standard alloys of C93200 bronze, aluminum bronze, and manganese bronze provide for extreme temperatures. . .from minus 400° F to 800° F. DEECO bearings are also available in cast iron and stainless steel which allow exposure to temperatures approaching 1200° F.

DEECO supplies graphited bearings in many other bronze alloys which may more specifically meet your needs. Consult us for particular application assistance.

  • Improved load carrying capability because the graphite transfers to the shaft. The resulting film reduces abrasive action and resists scoring.


  • Reduces friction compared to unlubricated bearing. Deeco graphited bearings have coefficient of friction of .04 to .09 for medium and heavy loads.


  • Nigh temperature capability, up to 1200° F, depending on material selection.


  • Maintenance free. Our graphite system requires no additional lubrication.


  • Graphite allows embedment of abrasive contaminants.


  • Reduces tendency for stick-slip start-up due to high resistance to pressure-induced migration of lubricant.


  • Resists ultra-violet, gamma-ray and other radiation.
  • Excellent for high load, low speed operation.



  • Cryogenic capabilities offered by these bearings to minus 400° F



  • Reduces product contamination, reduces fire hazards from volatile components, and maintains a cleaner and neat environment.



  • Reduces overall plant lubricant consumption and handling. No oilingdevice needed.



  • Excellent heat dissipation properties.



  • Resists corrosion and high temperature oxidation.



  • Performs extremely well in a vacuum.

Drilled and Grooved Patterns...


Sleeve Bearing Graphite Designs
Drilled and Grooved Patterns for graphited bearings. Grooves 5G, 7A, g and 10 are machined on our standard grooving equipment. The amount of graphite grooving required depends on the bore size and bearing length. Graphited grooves can be placed on one or both sides of thrust washers as desired, providing wall thickness permits.
