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.

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:What are the differences between cylindrical roller bearings nu208m and nu208em?: E means "reinforced", "rolling", "thickening", "change", "change".. Hope to adopt!!

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? ?: If the grease is dry, adhesion is not good, some of the high temperature grease stored for a long time will be dry, it will apply to the bearing is easy to get rid of, especially now the winter oil solidification, the lubrication effect is less. It is recommended to use low temperature grease in winter or add some oil to dilute it. The best way is to change the grade of grease. If the inner ring of the bearing can be removed, grease can be filled from it.

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: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: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:KOYO cylindrical roller bearings, //KOYO cylindrical roller bearings, how to determine the accuracy level?: The processing of the mating surface, especially the mating surface, is not done in a single clamping. The use of the bearing seat also causes misalignment, such as a flange bearing seat or a vertical KOYO inlet bearing block. As the work load causes the shaft to bend and deform, and also causes the inner and outer ring of the bearing to tilt, it will also appear misalignment.The main products are: KOYO bearing rolling bearing, deep groove ball bearings, high precision bearings, self-aligning bearings, bearings, plane ball bearings, cylindrical roller bearing, linear guide bearing, ball screw bearings, miniature linear guide bearing, cross roller guide bearings, reciprocating rotary bearings, ball bearing slide bushing, group cam follower.

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: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.

Q:cylindrical roller bearings N210 20Deep groove ball bearings 6120, self-aligning ball bearings 1210, cylindrical roller bearings N210 in the same radial force conditions, the life expectancy of the three levels and how to compare? What is the cause of the high and low?: Summary: the above three kinds of bearings, the service life in accordance with the order from high to low: deep groove ball bearings, self-aligning ball bearings, cylindrical roller bearings.
