How does the Self-lubricated Bearing Slide Plate reduce friction without external lubrication?

Self-lubricated Bearing Slide Plate can reduce friction without external lubrication, mainly through the following ways:

1. Application of solid lubricants
Self-lubricating bearing slide plates often use materials containing solid lubricants. These solid lubricants (such as graphite, molybdenum disulfide, polytetrafluoroethylene PTFE, etc.) can form a thin film between the slide plate and the contact surface, reducing the friction coefficient, thereby reducing wear and friction.

Graphite: Graphite has good high temperature resistance and low friction characteristics. When the slide plate surface contacts metal or other surfaces, graphite will form a self-lubricating layer on the contact surface to help reduce friction.

Molybdenum disulfide: This is a highly efficient solid lubricant that can withstand high loads and extreme environments and is still effective under high temperature and high pressure.

PTFE (polytetrafluoroethylene): PTFE has an extremely low friction coefficient and is therefore widely used in self-lubricating materials.

2. Distribution of lubricants and self-generated lubricating layer
Another key feature of self-lubricating materials is that the lubricant itself can be gradually released during use, forming a continuous lubricating layer. For example, some composite materials release lubricants during operation, and as friction occurs, the lubricants gradually penetrate into the contact surface through friction to maintain the lubrication effect.

Composite material design: These materials are usually composed of a polymer matrix mixed with solid lubricant particles. When the material is subjected to friction, the lubricant is released from the matrix and continuously lubricates the friction surface.

3. Matching of friction surface and lubricant

The design of self-lubricating bearing skateboards usually considers the tribological properties of the material, that is, the surface roughness, hardness and lubricant of the material. By optimizing these factors, friction can be reduced without external lubricants:

Surface structure optimization: The surface of the skateboard is finely processed or microstructured to enable it to better disperse the load and reduce the contact area. For example, micropores, textures or microstructures are used to better distribute the lubricant on the surface.

Hardness matching: The hardness of the self-lubricating bearing skateboard material is usually matched with the hardness of the contact surface to reduce wear and avoid excessive friction heat generation on the surface.

4. Temperature control and adaptive performance
Some self-lubricating materials can adjust their friction properties by adapting to temperature. For example, when the temperature is too high, some lubricants can be automatically released to form a thicker lubricating film; when the temperature is low, the amount of lubricant released is reduced, thereby preventing excessive accumulation.

5. Interaction between lubricants and substrates
The substrates of self-lubricating skateboards are usually materials with strong self-healing ability. These materials will wear slightly during the friction process, but at the same time, the lubricating components in the substrate will be brought to the contact surface, gradually forming a new lubricating layer, reducing friction and extending service life.

6. Load bearing and friction heat control
The design of self-lubricating bearing skateboards is usually able to maintain a stable friction coefficient under heavy loads while controlling the heat generated by friction. For example, some composite materials can disperse stress through the internal structure of the material under high loads, prevent excessive heat accumulation, and thus reduce thermal expansion and wear caused by friction.

7. Adaptability and stability
Self-lubricating bearing skateboards can self-adjust the lubrication effect according to different working conditions and maintain a stable friction coefficient. For example, the design of the skateboard material can adapt to different loads, speeds and working environments (such as temperature and humidity), ensuring that the friction force is always maintained at a low and stable level without external lubrication.

Self-lubricating bearing slides can reduce friction and maintain efficient and stable performance without external lubrication by using solid lubricants, optimizing friction surface design, self-generated lubricating layers of materials, and adaptability to the working environment. This technology enables self-lubricating bearing slides to operate effectively for a long time in some special applications (such as high temperature, high load, oil-free environment, etc.).
