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.

NJ 303 E,Cylindrical Roller Bearing Used Mower Wheels Bearings

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: Can you make it clear? I don't understand. Thank you for being here first.: The rollers refer to the rolling bodies as cylinders and similar cylindrical shapes, such as short columns, long columns, tapered rollers, spherical rollers, etc..

Q: Attention problems of cylindrical roller bearings: High temperatures often indicate that cylindrical roller bearings are in exceptional condition. High temperature is also harmful to bearing lubricants. Sometimes the bearing is overheated and can be attributed to the lubricant in the bearing. If the bearings are longer than the temperature of 125 degrees, even the transfer will reduce the bearing life. The causes of high temperature bearings include: insufficient lubrication or excessive lubrication, impurities in the bearing raceway, extreme high speed, long term overload operation of bearings, etc..

Q: Can cylindrical roller bearings bear high temperature?: A class of grease, temperature is not more than 120 degrees, and then high temperature will lose lubrication performance, leading to the bearings can not work, in fact, bearing itself can withstand high temperature.

Q: For bearing type, no outer ring single row cylindrical roller bearings, bore 40, thickness 21, roller diameter 8, roller length 12: This is the outer ring and the inner ring can be separated, the bearings in the country can be produced, imported bearings are sold.Another model is up to your standard,Cylindrical roller bearings SL183008Semi position bearing, full cylindrical roller, dimension series 30M 0,31 kgqualityCr 66000, NBasic rated dynamic load, radialC0r 67000, NBasic rated static load radialCur 11200, NFatigue limit load, radialNG 6300, 1/minLimit speedNB 4300, 1/minReference speed

Q: Is the nu240em cylindrical roller bearing split?: No, nu240em cylindrical roller bearings are integral.Bearing type: cylindrical roller bearingNew model: NU240EMOld model: 32240EHInternal diameter (mm):200Outside diameter (mm):360Width (mm):58

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: Cylindrical roller bearings, in the grease after the operation for a short period of time, the grease was thrown out (thrown to the end cap), resulting in roller and raceway between the lack of grease, lubrication poor. Decomposition found that the roller has round circumferential friction marks, but also on the roll, but compared to the roller is very slight. And there are relatively sound bearings, abnormal sound.Is this phenomenon normal? What if it doesn't work? What was the reason? What's the solution? StopThanks for your help!Assuming the grease is no problem, viscosity, consistency, selection is no problem If exclusion is the problem of grease, what other reasons can this be the case? ?: The higher the speed, the greater the centrifugal force, this point should be mastered. If the grease of good quality, from the bearing chamber to consider the change of the bearing chamber space, the sides of the bearing sealed by using injection nozzle gun grease can improve the lubrication condition.

Q: The thrust cylindrical roller bearings do not need the bearing seat, and the thrust bearings, shaft rings and seat rings on our unit are all in the bearing seat, often broken. The rotation of the 1. shaft in the bearing seat will not be affected, moreover, the shaft will have radial runout. 2. do not use the bearing seat, usually how to refuel?.Are there any field installation drawings or data on thrust bearings?. Thanks a million!: In general, this kind of bearing does not use the bearing seat

Q: Cylindrical roller bearingWhat are cylindrical roller bearings, are they available in Kunshan?: Because you do not know your request, can not provide you with more help, if necessary, you can ask.
