Main Product Features:

1. Roller and groove for line contact or repairing referral contact, radial load capacity, applicable to withstand heavy load and impact load.

2. Small friction coefficient,suitable for high speed limits,to deep groove ball bearings.

3. Installation error caused by the relative position of the shaft and the shell, can make use of the supporting free.

4. For shaft or block hole machining the demand is higher,after installation invading.this bearing relative to strict control axis deflection,

5. Ring in separable,convenient in installation and removal.

6. Main purpose:Large motor vehicles,motorcycles,spindle,internal-combustion engine,generator,gas turbines and reducer,rolling mill,the vibration

Q: Double row full cylindrical roller bearings, NNCF5008 installation, we need to pay attention to the direction of it?: In theory, cylindrical roller bearings provide radial force, so there should be no direction.

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: 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!: There is some doubt about your description. According to your internal diameter and external diameter, if the cylindrical roller bearings, the scroll is quite small. I don't see much of this kind of cylindrical roller bearing. Do you mean needle roller bearings? If needle roller bearings can be found, and HK2514/18 RS similar models.

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: 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: My notes is the former has a taper hole on the cone position preload, the latter is a nut. But the online information seems a little different. Are the preload methods for two direction thrust angular contact bearings and angular contact ball bearings the same?: Dissimilarity！ The former is mainly used as the support of the shaft with larger load. The main prevention is the radial runout, which is usually used individually, so there is not much demand for the preload. The latter is mainly used as a precision screw shaft for the radial motion and axial runout requirements are very strict, generally used when they are two back-to-back, when pre tightening have strict requirements, general requirements for the radial motion and axial runout should not exceed 5 per thousand mm.

Q: Why cylindrical roller bearings can not bear axial load?.: Bearing bearing axial force or radial force is determined by the structure of the bearing, thrust ball bearings are also called plane bearings, which are mainly used to bear axial force; cylindrical roller bearings can bear radial forces and are not suitable to bear axial force.

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: 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.

Q: Why should the main shaft be coupled with double row cylindrical roller bearings?: Separable, easy to install and disassemble, mainly used in lathe, milling machine, machining center and other high-precision machine tool spindle. Hope to be of help to you.
