What Is A Oiles#2000 Sinter Bearing
#200 sinter bearing is a composite bearing composed of porous special oil-containing wear-resistant material and metal steel back. The special wear-resistant layer is made of special copper alloy powder and solid lubricant whose main component is graphite dispersed on the metal matrix and sintered at high temperature. Treated with oil; since the solid lubricant is uniformly dispersed in the alloy layer, a solid lubricating film can be formed at the beginning of sliding, this film has low shear strength, and can be firmly attached even under high static load conditions. The bearing surface is not easy to crack, so there is no creeping phenomenon under micro-movement; and the metal matrix provides high mechanical strength and dimensional stability. The result is excellent friction and wear characteristics.

• Meet in dry friction conditions, can be maintenance-free;
• Has a high carrying capacity;
• Wide temperature range -40–+120
• You can re-radiation environment and vacuum environment;
• Material has good electrical properties, without the static phenomenon;
• You can dust conditions and corrosive environments;
• Materials as needed for re-processing.
Metallic Composite Sinter Bearing
Metal self-lubricating sinter 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 a low friction bearing surface for the material, reducing the friction coefficient and thus greatly improve bearing life, compared to more conventional powder metallurgy wear resistance and high-temperature performance.
