we will be happy to provide you with the most satisfactory service! Production and sales of all kinds of products for Center cut flange Oilless bearing. High Quality。Good Price.
The Center cut flange Oilless bearings are machined from continuous cast bronze bar stock.
They are then milled and plugged with solid lubricant graphite based plugs. The plugged graphite bushings are great for applications where maintenance is difficult and where normal grease and oil based lubricants can burn off due to high temperatures.
The cast bronze base material gives these products stronger bearing abilities when compared to other self lubricating bronze bushings.
Center cut flange Oilless bearing is the self-lubricating bush which is based on the metal friction surface of the bush basement where holes are spread reasonably in the proper size and a specific solid lubricant that has a self-lubricating function is inserted, This kind of bush has included the advantages of the metal basement and lubricant materials that have the specific direction for producing chemicals. It has broken in the limit of general bush that depends on an oil film. 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. The products are widely applied in metallurgy and steel-rolling equipment, mine machinery, shipping machinery, shipping industry. Space voyage, hydraulic turbine, gas turbine, filling equipment, instruments, and weave machinery. It also has a wide range of applications in other industrial and agriculture machinery. And it is being used more and more widely.
The basement of the oilless bush depends on the work conditions of the bush itself.
The commonly used materials are high strength brass tin bronze, etc The inserted solid lubricant materials are mainly two kinds of which based graphite, MoS2 as well as PTFE. According to the bushings’ working conditions, it can ensure that the product can meet various temperatures, loads, movements, and medium through the combination between the different metal basement and solid lubricant and ensure that it can work steadily and credibly
1. Heavy-duty oil-free bearing with embedded solid lubricant base of the high-strength brass alloy. 2. Available without lubrication 3. It exhibits an excellent wear resistance in difficult locations of oil film configuration 4. It has excellent chemical resistance and corrosion resistance.
Applied to any industry’s purposes with over 300℃ For even higher. Such as steelworks, elongators, industrial baking ovens, heat treating ovens, heat exchangers, dynamos and supports for nuclear energy reactors, etc.
