- 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: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. Our factory uses the bearings of Changzhou Enke Bearing Co., Ltd., they have many kinds of bearings and meet various demands.
- Q:What does "cylindrical roller bearing" ENV mean?
- Cylindrical roller bearings, the basic model suffix ENV meaning:E: enhanced design with improved bearing load capacityN: the outer ring of the bearing is provided with a stopping grooveV: full installed roller (no cage)
- Q:Full use roller bearings
- The FAG space division has also been involved in the development of bearings and other NTN precision components for Airbus wide body passenger aircraft A380 engines. The fuel efficient Boeing 787 aircraft reduces consumption by 20% compared to similar NACHI aircraft fuels, thanks to its improved aerodynamics, better operating systems and lighter materials. From the general electric KOYO GEnx engine and the Trent 1000 engine Rolls-Royce also play a role in ensuring that the airplane plays a key role more fuel-efficient. This high performance, lighter weight engine bearing support also plays a key role in the engine. FAG Aerospace entered the concept of bearing development, the engine as early as 2005. TIMKEN bearings, China's general agent, the first prototype manufactured bearings are available in 2006 to provide general electric and Rolls-Royce, FAG rolling bearing device design factors. The first engine test operation, which took place in the fall of 2006, achieved very positive results. The civil aviation authority's approval process for the two engines will be completed by the end of 2007.. In the summer of 2008, the first batch of FAG bearings was delivered to the airline. The main production base for the FAG China production base in Shanghai and INA roller bearing Chinese sales center, as well as Germany, Canada, Sweden SKF bearing China general agent of American Timken FAG office production base. The key role of space rolling bearing FAG in Rawls Royce and general electric engine plays, FAG bearing supply of Boeing 787 aircraft, Japan NMB bearings, the two engines for the new long haul aircraft rely on Aerospace Corporation of FAG rolling bearing
- Q:Full use cylindrical roller bearings, uses and advantages?
- Otherwise, due to lack of lubrication and high-speed operation will cause more wear and tear. I am a bearing
- Q:Cylindrical roller bearings NUP2311E mounting dimensions: Da (max): 69Da (min): 64DB (min): 72DC (min): 80Da (max): 111What are the specific meanings of these dimensions? Thank you, master
- Da means shoulder diameter, that is to say, the maximum shoulder size is 69mm, and the minimum is 64mm
- Q:In the car there is a cylindrical roller, the size of the diameter of 25mm, the outer diameter of 32mm, width of 9.5mm, who knows what the standard size, have direct purchase Mody, thank you!
- Hello, according to the data you supplied, and the type of bearing you saidAfter my inquiry,Cylindrical roller bearings, without this specification, GB specifications are 25 diameter, 52 outer diameter height, 15 model is nu205eAlso, the inside diameter is 25, the outside diameter is 62, the height is 15. The model is nu305eGB specifications, I have herecontactLook at personal data
- Q:what does that mean? Please enlighten master, thank you.
- You should say that the Japanese NSK bearings? NSK, N216, E stands for high load cylindrical roller bearings, N216 EM, which represents high load cylindrical roller bearings, copper alloy solid cage. E, which means strengthening the design, so the load capacity of bearings is better than without E.
- Q:Why are there no double row cylindrical roller bearings in the mechanical design manual?
- Normally, the inner diameter of the bearing should be in interference fit with the shaft (for some light loads, too, with a transition fit).
- Q:Why does cylindrical roller bearings fail abnormally?
- Generally, the causes of abnormal failure of cylindrical roller bearings are as follows:1, cylindrical roller bearing manufacturing accuracy is poor, one end of the bearings with loose, and travel source is larger, bearing frame rigidity is poor. Or the bottom of the bearing seat is uneven.2, cylindrical roller bearings axis misalignment (misalignment) axis and the housing of the shoulder to the surface is not vertical, shell installation, bearing two or more holes, different axis.
