Q:GPS15 rig bearings, Hunan, Changsha,
With so many rigs, you can buy it directly from Wuhan Jintai Geological Engineering Machinery Co., ltd.... They have all rig accessories, very, very complete. You can call them 400
Q:How Changzhou Guangyang bearing assembly wages???
Which shop is tired, hard work, see how you do, I hope you can help
Q:How can the rod joint bearings be connected with other parts?
1. is the standard parts. The national standard is 2. GB/T 304.92008. 3., I have the latest electronic version of the national standard. If necessary, please contact me at the station and inform me of the email address. I will send it to you.
Q:Since what year did NSK begin to provide bearings and other related components for the aircraft industry?
People all over the world can see the strong side of our great motherland! Satellite rockets are carrying the national flag to the universe again and again; tall buildings stand on the streets; science and technology are developing at the forefront of the world!
Q:Analysis of the problem: when other conditions remain unchanged,
When the other conditions are constant, the bearing life will be 0.125 times as much as the equivalent dynamic load suffered by the ball bearing. (0.5^3).When the other conditions are constant, the bearing life will be half of the original when the speed of the ball bearing is doubled.To read, ah, there are formulas, ha ha.
Q:How are the bearings and shafts fitted together?
Standard installation method: the bearing heating, the use of thermal expansion and contraction principle, installation time and effort, delaying bearing life, knocking bearings will destroy the bearing accuracy, coordination clearanceTeacher craftsman installation method: no fixed tools, sleeve, hammer, basic equipmentSpecial tips on what tools are for
Q:Yoyo how can I wash the bearings without gas?. What other materials can I use?
Thinner, acetone, chloroform, banana water, kerosene.
Q:In engineering practice, for needle roller bearings, usually axial positioning is the same as other bearings?
Needle bearing features are axial can not bear the load, so the operation of the axial direction of the bearing no force, radial installation slightly tight can be, the axial need not limit
Q:In bearings, why are the flanges connecting the upper and lower cases higher than those of the other bearings?
If it is understood as the reducer, the upper and lower box connecting the flange (bearing box outside the prominent part), the reason is to prevent the bearings in operation, gear and box friction, damage box, reduce gear life.
Q:What are the advantages of ceramic ball bearings versus other bearings?
1, insulation bearings;2, light weight, less heat, you can have higher working limit speed.
