Self-lubricating bearings are required by special production processes. In fact, these conditions have exceeded the range of oil and grease lubrication. Some key equipment of industrial and mining enterprises are operating under extremely harsh conditions. So far, most domestic enterprises still use traditional Lubricating oil and grease, due to heavy equipment, high ambient temperature, large dust or acid corrosive gas CO, SO2, etc., the lubrication of the equipment brings many problems, and the friction and wear are serious. Self-lubricating bearings are prone to biting or biting of bearings and other friction pairs, causing severe wear and damage to parts, often resulting in equipment failure.

Self-lubricating bearings In order to produce continuous operation, in addition to installing multiple equipments in the original design, automotive manufacturing, cement production, petrochemical and other enterprises have proposed to provide special lubrication materials under complicated working conditions. Therefore, the research on mosaic self-lubricating composite materials requires the installation of a large number of maintenance personnel. Seriously restricting productivity growth and consuming parts and energy have become important obstacles to production development. The self-lubricating bearing highlights its own characteristics in the material formulation and preparation process. The material performance has reached the international advanced level, which solves the lubrication problem under special conditions for the enterprise and brings obvious economic and social benefits.

However, for many reasons, Chinese companies have not yet passed. The composite material used in the self-lubricating bearing is a new type of pressure-resistant solid lubricating material. The self-lubricating bearing includes a metal-based material and a solid lubricating paste embedded in a hole or groove of the bottom material. The metal matrix is ??subjected to most of the load during the rubbing process.

After the self-lubricating bearing is rubbed, the solid lubricant in the hole or groove will transfer or reverse to the friction surface, and a solid transfer film with good lubrication, strong adhesion and uniform coverage will be formed on the friction surface, which greatly reduces friction and wear. As the friction progresses, the embedded solid lubricant is continuously supplied to the friction surface, ensuring long-term good lubrication of the friction pair.
