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

Product Applications:

Cylindrical Roller Bearing Application Flied:Rolling Mills,Crusher,Mining

Metallurgy Petroleum,Chemical Industry,Engineering Machinery,Port,Oil,Gas,

Wind,Agriculture,Lathe,CNC,Steel Works,Electrical Machinery,Axle/Limber,

Tractor,Autocar,Crude Oil Engine and so on.

NU 303 E,Cylindrical Roller Bearing Used Mower Wheels Bearings

Q:Can you make it clear? I don't understand. Thank you for being here first.: A rolling body is a short cylinder.The inner ring (or outer ring) of the bearing can be split.

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:How to calculate the clearance of bearings, such as 23226 double row cylindrical roller bearings: 1, radial clearance: non preload, bearing radial load, the radial clearance of G for any angle along the radial direction, in the absence of external load relative to the outer ring inner ring from a radial eccentric limit position, move to the opposite limit position of the radial distance arithmetic mean.2, axial clearance: non preload, bearing can withstand axial load in two directions, the axial internal clearance of G: without external load, a ring relative to the other ring, from an axial limit position toward the average axial distance limit position opposite the.

Q:Why are cylindrical roller bearings suitable for traveling support?: Should be the inner ring and the outer ring without the edge of the can do moving 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:Why should the main shaft be coupled with double row cylindrical roller bearings?: Because double row cylindrical roller bearings with high carrying capacity, high precision, separation, easy installation and disassembly, mainly used in lathes, milling machines, machining centers and other high-precision machine tool spindle. Hope to be of help to you.

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:How much is the axial force of double row cylindrical roller bearings? How is it calculated?: The cylindrical roller bearings have ribs can withstand certain axial force, the axial force for cylindrical but still belongs to the non normal stress, can cause early failure of the bearing, it is generally not given the axial bearing capacity, no formula

Q:How are the twin row cylindrical roller bearings classified?: Classification of double row cylindrical roller bearings:The NN0000 type cylindrical roller bearingsThe bearings are compact in structure and small in deformation under load, so they are especially suitable for the support of the spindle of machine tools. Because of its no outer wall, so you can install the outer ring and the inner ring assembly respectively (with roller and cage), does not limit the axial displacement of the shaft or housing, compared with the single row cylindrical roller bearing with the same radial size, can bear larger radial 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!

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
