March 18, 2019

china latest news about We Stock And Manufacture Sliding Bearings Solution Din 1494/Iso 3547 Standard Different Materials Bushings Are Available

We Stock And Manufacture Sliding Bearings Solution Din 1494/Iso 3547 Standard Different Materials Bushings Are Available made to order from china.

We have a large selection of plain sleeve spilt bushes and flanged bearings for various applications. With more than inch size dimensions in our china factory and with the co-operation of skilled subcontractors, we are one of the most reliable sliding bearings bushing suppliers available. With us you can order your self-lubricating bearings according to your own drawings and specifications or you can choose from our large size and small size and wide standard selection. In addition, our short lead times and good logistics makes us an efficient and reliable partner.

What is the principle of self-lubrication of oil bearing in powder metallurgy?
The principle is the hole!The hole holds the lubricant.When the rotation temperature of the bearing increases, the viscosity of the oil decreases. At the same time, the oil is heated to expand and oozes out of the hole to form an oil film for lubrication.After stopping the rotation, the temperature decreases, the oil cools and contracts, and is sucked back into the hole under the action of capillarity.Another is that, in the process of rotation, the bearing oil from one direction into the hole, and then from the other direction of the hole from the leakage to the working face, so that the oil in the shaft continuous circulation.

 

BUSHING TYPE
1: straight bushing
2: flanged sleeve bushing
3: the plate
4: gasket
5: washer

 

 

 

Major factors affecting longevity

 


1: load P: the greater the load, the shorter the service life of the bearing;Under no circumstances shall the maximum load exceed the theoretical maximum allowable load.
2: speed V: the higher the speed, the shorter the service life of the bearing;Under no circumstances shall the maximum sliding speed exceed the theoretical maximum allowable value.
3: PV value: the working life of the bearing depends on the PV value, that is, the product of the actual load P and the sliding speed V. The smaller PV value is, the longer the bearing life is.
4: temperature: the life of the bearing also depends on the temperature when the bearing is in use, the higher the temperature, the shorter the life of the bearing, so in the design and selection should try to consider the heat dissipation characteristics of the relevant parts.
5: surface roughness of the grinding parts: alloy steel or hard chromium plated shaft is used for the grinding parts. When the surface roughness Ra=0.4-0.63, the service life of the bearing can be significantly improved.
6: other factors such as bearing design, lubrication conditions, etc
