NU style with double outerrid, and the outer ring, roller,cage can separate from the inner ring.


Bearings single row cylindrical roller, model NU304


Product Features:

The rollers of the cylindrical roller bearing are usually guided by two flanges of a ring.

Because this assembly part composed of cage, roller and guide ring can be separated from

another ring, the cylindrical roller bearing belongs to separable bearing. This type of bearing

can be easily mounted and dismounted. Its advantages are obvious especially when there is

interference fits between the inner, outer ring and the axis, housing.

This bearing is usually subjected to radial load, only the single-row bearing with inner& outer

rings flanges can bear small steady axial load or great intermittent axial load. It has a high

requirement on the processing of the fitting parts such as axis and housing bore, etc.


Product Application: 

Cylindrical roller bearings are mainly used for:

- Iron and steel metallurgical industry

- medium and large motor

- generator

- combustion engines

- gas tuibine

- machine tool spindle

- speed reducer

- loading and unloading machinery and all kinds of industrial machinery


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!
This could be a car only bearing! NSK sample short column can not find the corresponding model!
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!
Q: Why does cylindrical roller bearings fail abnormally?
5, improper reinforcement of uranium bearing seat, so that the bearing capacity of the axle is uneven, the bearing seat is provided with holes, or some fasteners, such as a compression screw, etc., are supported, and the supporting parts are provided with grooves or printing places near the roller track of the cylindrical roller bearings.
Q: What are full cylindrical roller bearings?
Full cylindrical roller bearingCommon cylindrical roller bearings1, single row full cylindrical roller bearingsNCFNJG2 、 double row full cylindrical roller bearingNNCLNNCFNNCNNFTwo, not common full cylindrical roller bearings1, full spherical cylindrical roller bearings2, CARB ring roller bearings
Q: What's the difference between imported bearings and imported bearings?
Domestic bearings used in the cage and rivet and washer, spacer ring, sealing ring, pillar, pin etc. the material is divided into black metal materials (such as low carbon steel, stainless steel etc.), non-ferrous metal materials (such as brass, bronze and Aluminum Alloy etc.) and non metal materials (such as plastics, phenolic textolite three) etc..
Q: What does "cylindrical roller bearing" ENV mean?
Cylindrical roller bearings, the basic model suffix ENV meaning:E: enhanced design with improved bearing load capacityN: the outer ring of the bearing is provided with a stopping grooveV: full installed roller (no cage)
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: 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: 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.
