Oilless Thrust Washer

Metric Solid lubricated Thrust Washer Part number:

SPW material is made with high-strength copper alloy, and the inserted solid lubricant materials are made with graphite and PTFE.

According to the bushings’ working conditions, the bronze combination between the different metal basements and various solid lubricants can ensure that the product can perform under various temperatures, loads, movements, and mediums as required.

Oilless bush is especially applied in oil-free high temperature, high load, low speed, contamination resistance, corruption resistance radiation resistance as well as the use under such special work conditions that cannot be lubricated, such as underwater and in vacuum space.

Key Characteristics:

1. May work without any oil for long period.
2. Extremely high load capacity, good anti-wear, and low friction.
3. Particularly appropriate for low speed and high load.
4. Suitable single direction axial loads
5. Free design is possible on the shape and size
6. Can be used in a wide range of temperatures, from - 40℃+ 30

1. Where possible, try to use standard design;
2. Please note that the surface of any foreign body assembly;
3. Sliding surface after use, because the solid lubricant film formation results in a surface with black or gray-black phenomenon, please do not scrub, as usual;
4. Before assembly, if the lubricating oil is applied to the wear parts, can shorten the running-in period, in favor of mechanical operation, operation;
5. The assembly should be slowly pushed forbidden beat, so as not to damage bearings and cause deformation;
6. Design should be used in different parts of the appropriate material, in order to improve the mechanical properties, extending bearing life;
7. In the high load, the reciprocating motion, it is recommended to use screws;
8. In freshwater, seawater, and at sea, the shaft, or recommend the use of stainless steel, chrome plated.

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.
