High Strength Carbon Graphite Bearings High Purity Graphite Sleeves
Construction: Carbon graphite bearings are typically made by combining carbon/graphite fibers with a resin binder, which is then molded into the desired shape and cured at high temperatures. The resulting material is highly resistant to wear, heat, and chemicals.
Types: There are several types of carbon graphite bearings, including plain bearings, thrust bearings, and radia bearings Each type is designed to handle different types of loads and stresses.
