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:How to check the thrust cylindrical roller bearings?: However, in the conventional design, there are few checking bearings, as long as the shaft and shell meet the intensity requirements on the line, because the manufacture of bearings than ordinary mechanical parts to be much more stringent (except shoddy products).If you do your homework, do it according to the design manual.

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:Which column roller bearing brand is good?: you can look at yourself, they recently in the Qingdao market to great influence, you can understand.

Q:Full use cylindrical roller bearings, uses and advantages?: Full cylindrical roller bearings are designed to withstand heavy loads. At the same width, this kind of bearing, compared with the traditional belt cage bearing, has a very high carrying capacity, radial cross-section is small, it can save space, but the speed is relatively low.

Q:KOYO cylindrical roller bearings, //KOYO cylindrical roller bearings, how to determine the accuracy level?: Bearing accuracy grade standards for, divided into 0, 6X, 6, 5, 4, 2, six grades.The accuracy of bearings is increased in order of magnitude 0, which is adequate for general 0, but requires 5 or higher accuracy when used in other conditions or situations.In most cases, it is sufficient to apply KOYO bearings (tolerance grade PN) with general dimensional accuracy and rotational accuracy. When higher requirements are required, the bearings require higher levels of accuracy, for example, the spindle axis of the machine toolBearing. In order to achieve higher precision requirements, the standard specifies the tolerance levels of P6, P6X, P5, P4 and P2. KOYO also specified P4S, SP and UP tolerances for some special bearings in accordance with company standards.

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:Attention problems of cylindrical roller bearings: 4, when the interference is large, the oil bath heating or inductor heating bearings can be used to install the heating temperature range of 80 degrees -100 DEG C, the maximum can not exceed 120 degrees centigrade. At the same time, the nut or other appropriate method is used to fasten the bearing so as to prevent the contraction of the bearing in the direction of width and to create a gap between the collar and the shaft shoulder. 5, single row tapered roller bearings installed, the final adjustment should be clearance. The clearance value shall be determined according to the working conditions and the magnitude of the interference fit. Test shall be carried out when necessary. Double row tapered roller bearings and pump shaft bearings have been adjusted for clearance at the factory, and no adjustment is necessary during installation. 6, the bearing should be installed after the rotation test, the first for the rotary shaft or bearing box, without exception, then the power for no load, low speed operation, and then gradually increase as the functioning of the rotation speed and load, and to detect noise, vibration and temperature, abnormal, should stop running and check. The running test is normal and can be used before delivery.

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

Q:Double row cylindrical roller bearings how to disassemble?: The inner ring is heated and expanded and removed rapidly; flame cutting is used directly.

Q:Can it be used for axial alignment? Forty-fiveWhat is the function of the flat retaining ring of NUP cylindrical roller bearings with flat retaining rings? Can it be used for axial alignment?How much axial force can I bear then?You are the ZWZ? Can you make a friend?!How much axial force can you bear? Do you have a formula or a recommended value?NUP is needle roller bearings, brothers, I dialed the wrong number:What is the function of the flat retaining ring of the needle roller bearing with flat ring NUP? Can it be used for axial alignment?There seems to be no experts here, all mixed up: Yes, the function of the flat ring is to bear the axial force and be used for axial positioning.
