Maintenance-free Oilless Washers, Oil Free Washer

Oilless washers, also known as self-lubricating washers, are used in applications where traditional lubrication is challenging. They are made of cast bronze with solid lubricant inserts, such as graphite, to provide continuous lubrication without the need for external lubrication. These washers are suitable for high-load and medium-speed applications and can be developed to specific customer requirements. They offer advantages such as reduced maintenance, low friction, and excellent emergency sliding properties. The solid lubricant, typically covering about 25-30% of the bearing surface, reduces wear and extends the life of the bearing or thrust washer.

Thrust washer bearings with solid lubricant plugs, such as graphite, are essential components in various industrial applications. They provide continuous lubrication, eliminating the need for external lubrication and reducing maintenance costs. These bearings offer low friction, excellent emergency sliding properties, and can function even in case of unexpected failures. They are designed for high-load applications and can be grooved to provide additional lubrication distribution. The use of graphite plugs in these bearings provides several benefits, including self-lubrication and the ability to withstand high temperatures and pressures.

Features Self Lubricating Thrust Washer Lubricant

Caution

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.
