At present, NTN import bearings used in various machinery industry mostly ball bearing, needle like, only a small part of the self-lubricating bearing, I believe that in the near future self lubricating bearings will be adaptable, wear resistance, economy beyond all dispute advantage of bearing industry leading products. The following is the characteristics and advantages of the application of imported from NTN bearing lubrication: no oil lubrication NTN bearing imports series
1, no oil lubrication or oil lubrication, can not apply to refuel or difficult places, can be in use without maintenance or less maintenance time.
2, good wear resistance, friction coefficient of small, long service life.
3, with the right amount of elastic-plastic, the stress distribution in a wide contact surface, increase the capacity of NTN imported bearings.
4, the static and dynamic friction coefficient is similar, can eliminate the low-speed crawling, so as to ensure the accuracy of the mechanical work.
5, can reduce the mechanical vibration, reduce noise, prevent pollution, improve working conditions.
6, in the operation process of the transfer film can be formed, plays the role of protecting the shaft, shaft phenomenon no bite.
7, for the shaft, the hardness is low, without quenching of the shaft can be used, thereby reducing the processing difficulty of the relevant parts of the.
8, thin-walled structure, light weight, can reduce the machine size.
9, steel plating on the back can be a variety of metals, can be used in corrosive media; sliding parts, has been widely used in various machinery such as: printing machines, textile machines, tobacco machinery, micro motor, automobile, motorcycle and forestry machinery and so on.
The boundary lubrication import self lubrication NTN bearing series
1 bearing good, good wear resistance.
Rotary motion, 2 for high load low speed rolling motion and often open and close frequently under load and difficult to form hydrodynamic lubrication occasions.
3 under the condition of boundary lubrication can not long-term maintenance and refueling, refueling over layer so that the NTN import bearings last longer.
The 4 surface of the plastic layer can leave some margin in the molding process, fitting into the hole on their own after processing, in order to achieve better assembly dimensions.
The 5 products are mainly used in automobile chassis, metallurgical machinery, mining machinery, hydraulic machinery, construction machinery, agricultural machinery, steel rolling equipment etc.. JDB inlaid solid NTN import bearings of series JDB inlaid solid NTN import bearings series products is the basic universal, regardless of high pressure, low pressure, high temperature, low temperature, lubricating oil, no oil or water lubrication, can adapt to. Product material is high strength brass, more than doubled in copper sleeve hardness, and wear resistance increased one times above. Widely used in: light industry machinery, heavy machinery, construction machinery, metallurgical machinery, transportation machinery, such as: continuous casting machine, rolling machine, injection molding machine, paper machine, mold guide column, ships, machine tools and so on.
