- Q: A bearing assembly that can withstand greater torque (other requirements are not required and the axle is cantilevered)
- In addition, do not know in the operation process with no axial force, you can use two sets of spherical roller bearing.
- Q: 22318CA are there any other bearings that can be used instead?
- If you think the 22318 speed is not high enough, you can get a 2318 instead. But! 2318 of the load is not 22318 high, must confirm the load before changing
- Q: FAG bidirectional thrust angular contact bearing 234416M.SP can be replaced by other manufacturers?
- Japan NSK Code: 80TAC20XLJapan NTN code name: 562016SKF code name: 234416TN9/SPDomestic HRB Code: new code name: 234416. Old code name: 2268116
- 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 about the other workshops? Yes, I have a share in it. Which workshop is better in Changzhou?,
- Which shop is tired, hard work, see how you do, I hope you can help
- Q: Bearings radial, in addition to the location of contact with the box, there is no other way?
- 2. the outer ring of the bearing outer ring of the bearing outer ring is arranged in the outer hole of the outer shell, and the inner side of the outer hole of the outer shell generally has the position of the shoulder fixed bearing, and the other side is positioned with an end cover, a thread ring and a hole, and an elastic ring ring. (1) the end cover positioning end cover is used for all kinds of radial bearings and angular contact bearings. When the bearing speed is higher and the axial load is larger. The end cover is positioned and pressed with a screw to compress the outer ring of the bearing, and the end cover can also be made into a labyrinth sealing device. (2) thread ring bearing high positioning speed, axial load, not suitable for use under the condition of end cap positioning, available thread ring positioning radial bearing and thrust bearing, this can be used to adjust the axial clearance of the bearing. (3) the axial position of the elastic ring positioning method is small, the installation and disassembly are convenient, the manufacture is simple, and the utility model is suitable for bearing smaller axial load places. An adjusting ring is added between the bearing and the spring, so that the axial position can be adjusted conveniently. (4) the deep groove ball bearing with a stopping groove on the outer ring of the bearing can be fixed by the retaining ring. This type shall be used when the inside of the housing hole cannot be machined because of the condition limit, or the part must be reduced in outline size
- Q: Is there any difference between plain bearings and other bearings?
- There are sliding bearings and rolling bearings.Sliding bearings: as the name suggests, is the way it works, with sliding, that is, the relative movement of the inner ring and outer ring is sliding (contact mode is face to face contact), generally used for low-speed, heavy load placeThe rolling bearing is: work is rolling on the rolling ball to realize high speed rotating sliding bearing and complex structure than the inner and outer ring cage and ball to the point contact are generally used for high speed and low load.
- Q: What are the world bearing giants?
- International bearing giants:Sweden: SKF (SKF group)Germany: INA/FAG (Schaeffler group)United States: TIMKEN (The Timken Company)Japan: NSK (Nske) NTN (NTN) KOYO (Guang Yang) NACHI (fujikoshi)NMB (Mei Beiya) THK (main line, unit FYH (bearing) main bearings etc.)
- Q: I feel different from other factories, ah, there is no pungent smell!
- You go to Harbin axis Ji'nan company to ask, they are the factory's direct center, can solve your problem
- Q: sometimes to the other bearing sliding bearing number, sometimes to the sliding bearing parts inside, why?
- Sliding bearing partsThe bearing is sliding bearing and shaft parts, very smooth, generally made of bronze, anti friction alloy wear-resistant material, in particular, can be made of wood, plastic or rubber. Also called the "Bush", is in the shape of half cylinder tile.
