Product Description:


bushing for leaf spring:
1,high quality low carbon steel back to substrate.
2,the surface of sintered bronze alloy Pb-Sn.


Bushing for leaf spring Bimetal bearing bush Clutch Bimetallic bushing 




      1.  Bimetal bearing bush has a combination of high strength, load-bearing capacity, and the advantages of good wear resistance. Particularly suited to medium-speed and low-speed high-contained set and so on.

      2. Process through special means, at the friction surface can be processed into a variety of oil and oil hole and the hole in order to adapt to different working conditions lubrication use.


      3. Products widely used in automotive engine, chassis, motorcycle clutch, gear pump rub board and lifting equipment and other fields.

Q:What will cause the friction coefficient to be inaccurate in a hydrodynamic sliding bearing?
The gap between the shaft and the hole, the shaft speed of these two factors is more critical, gap control is not good, there is no way to form a good oil film, that is, can not form a complete liquid friction
Q:Plain bearings are linear bearings? Are they different?
Journal bearings are a large class of bearings. General bearings can be divided into rolling bearings and sliding bearings.
Q:What are the differences between rolling bearings and plain bearings? What are their respective applications?
The friction coefficient of rolling bearing operation, some high precision rolling bearing which can bear radial load and axial load, lubrication oil consumption, convenient installation, rolling bearing is smaller than the sliding bearing and realized standardization and universalization, use and maintenance is very convenient, can be used in the manufacture of sliding bearing is more expensive the non-ferrous metal saving; but the rolling of metal debris and other foreign bodies are particularly sensitive to the rolling bearing life shorter than the sliding bearing, bear the load bearing capacity than the same volume of plain bearings is much smaller, because of this, the radial bearing large size.
Q:The sliding bearing consists of several parts. What are the parts?
Sliding bearings (sliding, bearing) bearings that work under sliding friction. Plain bearings work smoothly, reliably and without noise. Under the condition of liquid lubrication, the sliding surface is separated by the lubricant without direct contact, and the friction loss and surface wear can be greatly reduced. The oil film also has a certain vibration absorption capacity. But the starting friction resistance is larger. The shaft supported by the bearing is called the journal, and the part that matches the journal is called the bush. In order to improve the friction properties of the bearing surface, the antifriction material layer, which is cast on its inner surface, is called the bearing lining. Bearing and bearing lining materials are collectively referred to as journal bearing materials. Sliding bearing applications are generally under low speed heavy load conditions, or maintenance and lubrication of the difficult parts of the operation.
Q:Is the high or low pair of plain bearings and shafts?
The element of the moving pair of sliding bearings is surface contact, which is low pair!
Q:What is the clearance ratio between the plain bearing and the shaft?
I don't think so. I do rolling bearings, I'm sorry
Q:What is the relationship between the eccentric e of the sliding bearing and the external load and the bearing speed?
With the increase of the external load, the Z increases and the speed decreases
Q:What are the uses of sliding bearings and rolling bearings and their classification?
East China bearings for surface and surface contact, reduce friction, rolling bearings for shafts in the hole rotation, reduce friction, classification more, go to 0, 9 kinds, anyway, is a lot of ah!
Q:What's the difference between plain bearings and oilless bearings?
Compared with plain bearings, the advantages of rolling bearings:1, the general condition, the rolling efficiency and hydrodynamic bearing lubrication bearing, but higher than the mixed lubrication bearing; 2 radial clearance is relatively small, the centripetal angular contact bearing preload available available pretightening force to eliminate the clearance, operation and high precision; 3, for the same size of the shaft diameter, bearing width ratio the sliding bearing is small, the axial structure of machine is compact; 4, most of the rolling bearing can be both radial and axial load, the bearing assembly has the advantages of simple structure, less consumption of lubricants;
Q:Why sliding bearings are divided into bearing housings and bushes, and sometimes on the bearing shell with a layer of bearing liner
Sliding bearings should be divided into bearing seat and a bearing, sliding bearing inside the bearing seat because the inside of the bearing seat can be replaced, you can not change, so join the bearing in the bearing, and bearing in putting a layer of bearing liner,
