Product Specifications:
Cylindrical roller and race for line contact bearing. Load capacity is big, mainly bear radial load .
1. Friction coefficient is small, suitable for high speed limit speed close to deep groove ball bearings
2.N and NU type axial movement, can adapt to shaft caused by thermal expansion or installation error and shell the change of relative position, can be used for free end bearing
3. On the shaft or hole of the processing and the demand is higher, bearing outer axis relative deflection after installation to be kept under strict control, so as not to cause contactstress concentration
4. Inner ring or outer ring separable, easy to install and remove

- Q: NSK cylindrical roller bearings EW/EM series of differences and characteristics
- E international is called "reinforced type" load, also means to increase rolling bodyW international is called a steel cage
- Q: Which column roller bearing brand is good?
- Foreign SKF is better, the domestic is Kazakhstan axis, and then is Taiwan's Rui Rui, you can look at yourself, they recently in the Qingdao market to great influence, you can understand.
- Q: How to check the thrust cylindrical roller bearings?
- Bearing dimensions (or bearing samples) have "basic rated load (KN)", this column can be directly detected, in general, according to the use of appropriate multiplied by a (1.2~1.5) safety factor. In accordance with the requirements of the design manual, the equivalent load can be calculated (considering the speed, temperature, load and stability).
- Q: Can the Nu and N type NJ NUP cylindrical roller bearings bear axial force?
- The answer upstairs is clear. Such bearings can not be designed with axial force. In use, the inner and outer rings of the bearing can have larger axial displacement, and the aim is to compensate the length change caused by the rotating part of the two bearing due to the temperature rise.
- Q: Can you make it clear? I don't understand. Thank you for being here first.
- Oh, My God！！！ Do you understand the bearings in this way?! What is called "roller" means that the rolling column is cylindrical and similar to cylindrical shape, such as short cylindrical, long cylindrical, tapered roller, spherical roller, etc.." This kind of statement should be listed as the promotion answer!!! Absurd! Laughable! !!The standard answer is: Bearings in accordance with the direction of force, divided into radial bearings and thrust bearings, in simple terms, if the main force to bear the axial thrust bearings, thrust bearings; otherwise, that is, radial bearings. As for radial roller bearings, simply speaking, it is the roller bearings that mainly bear radial forces. It's so simple, there's so much nonsense!!!
- Q: For bearing type, no outer ring single row cylindrical roller bearings, bore 40, thickness 21, roller diameter 8, roller length 12
- Specific circumstances need to be further confirmed with your drawings.Reminder: please buy the product specifications and product quality guarantee, so as not to buy fake and inferior bearing products.Handmade, thank you for your adoption, and if you have any questions, please continue to ask.
- Q: What are full cylindrical roller bearings?
- Full cylindrical roller bearingCommon cylindrical roller bearings1, single row full cylindrical roller bearingsNCFNJG2 、 double row full cylindrical roller bearingNNCLNNCFNNCNNFTwo, not common full cylindrical roller bearings1, full spherical cylindrical roller bearings2, CARB ring roller bearings
- Q: What are the components of cylindrical roller bearings?
- The utility model has the advantages of convenient installation and disassembly, especially when the inner, outer ring and the shaft and the shell are in interference fit. Such bearings are generally only used to bear radial load, only the inner and outer ring with single block bearings can bear less axial load or larger intermittent axial load.
- Q: For example, NU, NJ, N, RNU, NUP, NF, NO, NN, RN, what do you mean, who can tell me about that hero?
- N outer ring without edge, inner ring double edgeRNU no inner ring, NU typeNUP outer ring, double retaining ring, inner ring, single edge, with flat retaining ringNF outer ring, single edge, inner ring, double edgeNO doesn't know
- Q: Thrust cylindrical roller bearings, the main use?
- Thrust cylindrical roller bearings, the main use? Thrust cylindrical roller bearings are mainly used in oil rigs, iron, steel, machinery and so on.
