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.
Inspection
- 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: 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: Attention problems of cylindrical roller bearings
- 1. The installation of bearings must be carried out in a dry, clean environment. Before installation, the machined surface of the shaft and shell, the shoulder end, the groove and the joint surface shall be carefully inspected. All mating surfaces must be carefully cleaned and removed, and the cast surface must be clean. 2, before the installation of bearings, should be cleaned with gasoline or kerosene, dry after use, and ensure good lubrication, bearings generally grease lubrication, oil lubrication can also be used. Grease lubrication, grease, anti rust, extreme pressure and other excellent greases should be used. Grease filling capacity for bearings and bearing box volume of 30%-60%, should not be too much. Double row tapered roller bearing and water pump shaft bearing with sealing structure have been filled with grease, which can be used directly by users and can not be cleaned again. 3, bearing installation, must be applied equally in the circumference of ferrule end face pressure to press into the ring, and may not directly tap bearing end face to the top tool, so as not to damage the bearing. Small amount of interference in the case, at room temperature can be used to suppress sleeve bearing ring face, beating with a hammer sleeve, the sleeve will be pressed into the ring balance. If installed in large quantities, use hydraulic press. When pressing, the outer end surface of the outer ring and the outer shoulder of the shell face shall be ensured, and the inner ring end face is tightly pressed with the shoulder end of the shaft platform, and no gap is allowed.
- Q: Double row cylindrical roller bearings how to disassemble?
- If it is replaced, use the flame to heat it quickly under the conditions permitted! The inner ring is heated and expanded and removed rapidly; flame cutting is used directly.
- Q: What's the difference between imported bearings and imported bearings?
- The 2 kind of bearing retainer material is mostly copper, and the retainer pin is also copperThere is also a steel retainerImported bearings also have copper and steel
- Q: What are the components of cylindrical roller bearings?
- Compared with the deep groove ball bearings of the same size, this kind of bearing has larger radial load capacity, and is also suitable for high-speed rotation from the structure.
- Q: Is the nu240em cylindrical roller bearing split?
- Therefore, such bearings need to be installed in the axial load bearing the main components, only at the same time using other types of bearings to withstand axial load on the premise that can be used.
- 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!
- Rolling bearing face to face or back to back, the speed limit will be reduced? Yes, especially in order to obtain a large preload or a large gap of the matching. Cylindrical roller bearings in pairs, the limit speed will be reduced? Cylindrical roller bearings do not exist in pairs, one said that you can use the same internal and external diameter of double row, four column cylindrical bearings, the same internal and external diameter of double row, four column bearings, compared to single row cylindrical bearings limit speed will be reduced
- Q: How to calculate the clearance of bearings, such as 23226 double row cylindrical roller bearings
- First of all for the bearing clearance calculation is a very complicated problem, because the bearing structure of different types, and the usage of different materials, the temperature of different factors such as the clearance is different, and because of the different structure types and some bearing bearing clearance is divided into radial clearance and axial clearance; also need to pay attention to the bearing clearance is usually divided into the following 1. conditions, clearance before installation, usually refers to the bearing manufacturers factory according to the standard to determine the clearance of bearing clearance. 2., after the installation clearance, because the bearing inner ring and the shaft is interference fit, when the bearings installed on the shaft, its inner ring will be as the amount of interference and expansion, resulting in smaller clearance of bearings. 3. clearance work, because the bearing is affected by load and rotating friction in the work, the temperature will gradually increase, will cause the bearing inner ring further expansion, which will make further changes in bearing clearance. However, the main clearance of the bearing is the largest (minimum) diameter of the raceway of the outer race of the bearing, the largest (minimum) diameter of the rolling body and the largest (smallest) diameter of the raceway of the inner race. For example, cylindrical roller bearings, its largest clearance = outer raceway raceway, maximum diameter of -2* roller minimum diameter - inner raceway minimum diameter derived, and conversely, for the smallest clearance. The average user of bearings actually doesn't need to know that.The other 23226 models should be the spherical roller bearing, not double row cylindrical roller bearing.I hope my answer will be of some help to you!
- Q: Cylindrical roller and bearing outer ring processing is sheet metal forming?
- Bearing parts, the main size tolerances are fighting between 0.01 mm, ultra poor 1/1000 mm, are scrap. Tolerances for precision bearings are extremely stringent, such as the diameter of each steel ball (or roller) and the diameter of the inner and outer rings. Surface hardness of more than HRC60 (as a metal cutting tool material of high-speed steel, hardness is HRC65-68). High quality bearings, these are strictly controlled.
