Feature

FRB85H metal self-lubricating bearings made by powder sintering process, suitable for high load or fuel can dry friction conditions required under the conditions of work; the main materials include copper, iron base and stainless steel base, but also with the use of the bearing condition, the use of temperature, load, speed, and environmental requirements can choose, such as graphite, molybdenum disulfide solid lubricant such as different proportions, the solid lubricant materials uniformly distributed in the organization can continuously provide low friction bearing surface for the material, reducing the the friction coefficient and thus greatly improve bearing life, compared to more conventional powder metallurgy wear resistance and high temperature performance.

Solid lubricant

Dry friction mechanism

As the solid lubricant layer structure of crystalline materials are all easily within the metal matrix material between adjacent molecules to form a low shear strength of the interface, the initial friction occurs due to metal wear, solid lubricant can easily be released into the bearing surface formed with the combination of mechanical grinding parts; this layer transfer film has a high carrying capacity and low friction coefficient and can thus greatly reducing the supply of continuous extended wear life, the other in the event of damage to the transfer film can be very short period of time to repair itself, which played a maintenance role.
