Product Specifications:
cylindrical roller bearing , 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 contact stress concentration
4. Inner ring or outer ring separable, easy to install and remove

- Q:What are the differences between cylindrical roller bearings nu208m and nu208em?
- E means "reinforced", "rolling", "thickening", "change", "change".. Hope to adopt!!
- Q:Why cylindrical roller bearings can not bear axial load?.
- The thrust bearing retainer plate and two pieces of circular hole of the ball and the ball hole and shaft wear in the park, circular plate, steel ball track between two plate, shaft and the bearing seat of the top plate in the round two sides, in addition to the track groove, it is not binding the radial direction, so it cannot withstand the radial load.The radial bearing by the size of the two steel ring, steel ball size between steel ring, steel ring diameter fixed by a bearing seat, shaft mounted on a small steel ring, binding only in the radial direction and axial direction of the load is not binding, so it cannot withstand the axial diameter.
- Q:What is called a semi convex roller, a fully convex roller, a logarithmic curve roller?
- The logarithmic curve roller is also a convex roller, which belongs to a full convex roller;The shape roller refers to a roller which has a slight modification to the diameter of the outer end of the roller to prevent the stress concentration at the end of the contact between the roller and the raceway.The corresponding types of bearings are cylindrical roller bearings and tapered roller bearings. Modified roller and convex roller have been widely used in domestic roller bearings, which can improve the service life of the products.
- 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: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:How are the twin row cylindrical roller bearings classified?
- Double row cylindrical roller bearings have cylindrical inner bore and conical inner bore (bearing rear code plus K) two structures. This kind of bearing has the advantages of compact structure, large rigidity, large bearing capacity and little deformation after load. It is especially suitable for spindle support of machine tools. The conical inner hole can also play the role of micro adjustment of the clearance, and can simplify the positioning device structure, and is convenient for installation and disassembly.
- Q:Why are cylindrical roller bearings suitable for traveling support?
- Cylindrical roller bearings without inner sides of the inner ring or outer ring, whose inner and outer rings can be moved relative to the axial direction, so they can be used as free end bearings.
- Q:Rolling bearing face to face or back to back on the use of cylindrical roller bearing pairs, the speed limit will be reduced? Please, thank you!
- Well, as long as the shaft is well done and the structure is reasonable, what can't be done? I haven't seen the theory of 30%. Cylindrical roller bearings are easy to process, so they have high precision and high limit speed.
- 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:Double row full cylindrical roller bearings, NNCF5008 installation, we need to pay attention to the direction of it?
- Double row cylindrical roller bearings have no directionality, so they do not need to pay attention to the direction! However, it should be noted that the inner ring and outer ring should be positioned separately to prevent axial movement!
