Self-Lubricating Thrust Washers & Graphite Bearings Advantage

1. The design is flexible, simple, and convenient, and has a wide range of use;
The fuel supply system is a heavy-duty, time-consuming, and labor-intensive device in mechanical design. There is no need to consider the use of solid self-lubricating bearings when designing fuel, which saves fuel device equipment and can be applied to various special occasions. The solid self-lubricating bearings are designed in a variety of shapes to meet the needs of various special occasions. The use of solid self-lubricating bearings can significantly reduce the cost of mechanical maintenance and fuel.
2. No oil can be used;
Since the coefficient of linear expansion is greater than that of the solid lubricant of the metal matrix when the solid self-lubricating bearing starts to run, the piece will be transferred to the mill members to realize self-lubrication, so it is difficult to use solid self-lubricating bearings in oil and can not be oil or fat. Locally, even in the case of low speed and high load, it can also play a good lubrication effect.
3. Low cost of use;
With the traditional mechanical design, the fuel gauge should be checked at all times during refueling and maintenance within a certain operating time. The installation of the oil is smooth. Regular refueling will cause pollution to the surrounding environment and increase maintenance costs. After lubrication, not only can the environment be cleaned, but also the use cost of the lubricant can be greatly reduced.
4. Under high load and low-speed conditions, it can exert superior performance;
The solid self-lubricating bearing uses centrifugal casting high-strength brass alloy as a matrix, which plays a role in the load. The special formula of graphite with good self-lubricating performance is used as a lubricant, playing a role in self-lubricating, which combines their respective advantages, Even under high load and low-speed conditions, it can exert superior performance.
5. Reciprocating motion, rocking motion, and frequent start-stop film formation difficulties, exert excellent wear resistance;
The principle of the self-lubricating bearing arrangement of solid lubricants is to ensure that all parts of the grinding member have the role of lubricant during the operation. Therefore, the arranged lubricant must be arranged based on the direction of movement of the grinding to determine the location of the lubricant.
6. Excellent chemical resistance and corrosion resistance;
The solid self-lubricating bearing lubricant is specially formulated from graphite, polytetrafluoroethylene, molybdenum disulfide, and other wear-resistant materials. It has a stable molecular structure. The metal matrix can have different chemical resistance and corrosion resistance according to the metal selected. Therefore, solid self-lubricating bearings have excellent chemical resistance and corrosion resistance.
7. The product is more competitive in cost performance, compared with similar products, it has a long service life, less maintenance, a long replacement cycle, and good performance.

Oilless washer size

“Oilless bearing discs plate” refers to a specific type of bearing that does not require oil for lubrication. This might be achieved through materials or designs that reduce friction without the need for added lubricants.

When you mention “plugged graphite,” you’re referring to a technique used in the manufacture of some types of oilless bearings. Graphite has natural lubricating properties, and so ‘plugging’ the bearing material with graphite can create a bearing that self-lubricates as it operates. The graphite plug slowly releases graphite particles into the bearing interface, providing ongoing lubrication without the need for oil.

Overall, these features make oilless bearings with plugged graphite beneficial in applications where regular maintenance or lubrication is difficult or not possible, in certain high-temperature environments where normal lubricants might degrade, or in applications that need to be kept clean of oil or grease.

An oilless bearing, also known as a self-lubricating bearing, is a type of bearing that doesn’t require any external lubrication because they can operate under slippery conditions. This is possible due to the lubricating oil impregnated within the bearing material itself.

Here are some key points to understand about oilless bearings:

  1. Material: They are typically made of a composite material or metal coated with a layer of lubricant-containing substance. The most common types are bronze oilless bearings, plastic compound bearings, and bimetal bearings. The material choice depends on the application and environment.
  2. Self-Lubricating: The lubricant in oilless bearings is distributed throughout the material, and when the bearing is in operation, the heat causes the lubricant to flow to the bearing surface, creating a slick layer that reduces friction and wear.
  3. Maintenance: Because these bearings are self-lubricating, they require less maintenance than traditional bearings. This makes them a practical choice for applications where regular maintenance would be difficult or impossible.
  4. Applications: Oilless bearings are used in a variety of applications where maintenance is difficult, lubrication is undesired due to contamination concerns, or where a traditional lubricant could freeze or burn off. Examples include in machinery in the food industry, space equipment, underwater equipment, high-temperature equipment, and more.
  5. Advantages: Besides reducing the need for maintenance, they also prevent bearing failure due to inadequate lubrication. They can operate at a wide range of temperatures and are less susceptible to dust and dirt. In addition, they can reduce noise levels in comparison to traditional bearings.
  6. Limitations: However, they may not be suitable for all applications. In heavy-load or high-speed applications, traditional bearings might be more appropriate. Furthermore, although the self-lubricating property extends the bearing life, it does not last indefinitely and will eventually wear out.

In conclusion, oilless bearings represent a significant advancement in bearing technology. They offer a maintenance-free solution to many industries, extending the lifespan of machinery, and improving operational efficiency. They are not a one-size-fits-all solution, but when used in the right context, they can provide significant advantages.
