CuZn25A16Fe3Mn4 self-lubricating graphite die bearings from China
The VSB-JDB-1 solid mount bearing is located in a brass matrix. A high performance solid lubricant with solid graphite or MoS2 lubricants that interrupts the general lubrication of the bearings with limitations of the oil film. In the process of use, through the heat of friction to make the lubrication solid and the friction of the shaft, the formation of oil, the co-lubrication of the powders in excellent conditions.Its hardness is higher than average copper sleeve one times, wear-resisting property is also one times.At present, the product has been used in metallurgical continuous casting machine, train support, steel rolling equipment, mining machinery, ships, gas turbines and other high temperature, high load, low speed heavy load and other occasions.
· can be used for a long time without maintenance;
· designed for high static load and dynamic load;
· it has a very low and stable friction coefficient and no "adhesion" phenomenon;
· dust resistance, corrosion resistance, impact resistance and edge load resistance;
· the metal substrate has good shock-absorbing capacity;
· can be used in a wide range of temperatures;
· suitable for reciprocating, rotating and oscillating situations where startup is frequent and oil film is difficult to form;
· very low wear rate, long service life.

|Bushing inner-Ø after mounting||Pls consult our sales engineers, standard delivered tolerance: r6 or E7|
|The shaft hardness should be at least 70-100HB harder than the bronze alloy.|
|Surface roughness ≤ Ra 0.8|
|It fullfills the highest operational demands and is suitable for shock loads. Depending on the alloy, it is corrosion-resistant and also highly wear-resistant with a long life span.|
|RANGE OF APPLICATION|
|Cranes, mining machines, construction machinery, off-shore & marine applications, steel plant, hydro power & hydro mechanical|
|It is a maintenance-free bearing material, but an initial greasing is mandatory for the “running-in”process. A lithium aging-resistant grease should be used.|
|Housing||Chamfer min. 1.5 mm x 15-45°, for easy bushing alignment|
|Shaft||Chamfer 5 mm x 15°, for easy insertion of the shaft|
|For smaller diameters, the OD should be greased before pressing in.|
|For larger diameters dry ice for freeze fitting should be used.
1.No need of oil supply device, oil injection hole, oil tank processing oil supply device cost, processing cost, assembly cost and other excess costs and time savings, can significantly reduce the manufacturing cost.
2.The reduction in operating costs significantly reduces the amount of lubricating oil used and the cost of equipment maintenance, and also eliminates the risk of insufficient oil supply.
3.Shortening of design time oil-free can greatly simplify the design and structure, reduce the cost and save the design time. In addition, the use of self-lubricating bearings can also improve the mechanical properties, prolong the service life and improve the reliability and other aspects of significant results.
4.Oil recovery and environmental protection without waste oil recovery treatment, conducive to environmental protection.VSB-JDB(500#SP) self - embellishment bearing as a mechanical industry parts, has a certain sense of use.A lot of work has been done to make the mechanical drive run normally.The bearings are divided into rolling bearings and sliding bearings.General sliding bearing in high load mode of motion, foreign matter mixing, temperature conditions, oil supply, maintenance is not perfect, will cause hair.Under the harsh condition that such a general plain bearing cannot be used, the solid inlaid metal self-lubricating bearing's wear resistance and hair resistance can give play to the due performance of the bearing and realize the role of high performance and maintenance free of machinery.
