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.


● Since the solid lubricant is uniformly dispersed, it can be used under friction conditions in any direction of motion, and has good fretting wear resistance;

● Can be used without oil;

● High load, excellent wear resistance, excellent speed characteristics.

● Standard products and plates of various specifications can be provided for secondary processing;

● Protected by an oil film, it has a wear-resistant effect.

● Porous structure oil storage plays a self-lubricating effect.


● The low hardness of the sintered layer is easy to absorb the hard particles in the earthwork pile construction environment so that the guide plate and the dual structural parts are not easy to rough.

● Oil film protection can also reduce noise.

● Compared with other self-lubricating materials, it can resist the eccentric wear caused by vibration.

● The material can be freely processed and cut and is not restricted by the arrangement of solid lubricants.

● Avoids heavy metal pollution caused by smelting, and at the same time reduces the use of environmentally harmful components, making it more environmentally friendly.

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.
