Product Specifications:
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 contactstress concentration
4. Inner ring or outer ring separable, easy to install and remove

- Q:What are the differences between cylindrical roller bearings nu208m and nu208em?
- E means "reinforced", "rolling", "thickening", "change", "change".. Hope to adopt!!
- 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:Why does cylindrical roller bearings fail abnormally?
- Generally, the causes of abnormal failure of cylindrical roller bearings are as follows:1, cylindrical roller bearing manufacturing accuracy is poor, one end of the bearings with loose, and travel source is larger, bearing frame rigidity is poor. Or the bottom of the bearing seat is uneven.2, cylindrical roller bearings axis misalignment (misalignment) axis and the housing of the shoulder to the surface is not vertical, shell installation, bearing two or more holes, different axis.
- 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 is the limit speed and rated dynamic load of NSK full M40-19g cylindrical roller bearings, HTF?
- D - tapered roller bearings with a contact angle of 28 degrees. C, CA (with solid brass cage), CD (with stamping cage), spherical roller bearing with high load. E -- high load cylindrical roller bearing. H - thrust roller bearing high load. J - tapered roller bearings of the outer raceway, the small end diameter, angle, outer ring width is consistent with the provisions of ISO. (2) material G - ring, rolling body is carburizing steel. H - ring, roll for stainless steel. (3) holder M - copper alloy solid cage. T - synthetic resin cage. W - press holder. V - no cage. (4) sealing ring, dust cover Z, ZS - one side with steel plate dust cover. ZZ, ZZS -- dust cover for two side steel plate. D, DU - one side contact rubber ring. DD, DDU -- two faced contact rubber ring. V - one with a non-contact rubber ring. VV -- two side non-contact rubber sealing ring. (5) ring shape K - taper hole, taper 1:12. K30 -- taper hole, taper 1:30. E - there is a notch or oil hole in the ring. E4 - oil tank with oil holes on the outer ring. N -- outside outer diameter band stop groove. NR -- outer ring, outer band, stop groove, stop ring.
- 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:For example, NU, NJ, N, RNU, NUP, NF, NO, NN, RN, what do you mean, who can tell me about that hero?
- NN double row cylindrical roller bearing inner ring gear side no outer wallRN no outer ring type N cylindrical roller bearing
- Q:KOYO cylindrical roller bearings, //KOYO cylindrical roller bearings, how to determine the accuracy level?
- The allowable deviation of 1, the inner and outer diameter, width and the width of the assembly allowable deviation 2, roller diameter and the outer round round in group 3, the diameter of the chamfer size bounds value 4, the width of the allowable rotation accuracy (momentum and rotating body beating related projects) 1, inner ring and the outer ring allows for radial and axial beating 2, inner ring 3, allowing the lateral runout of outer surface inclination to allow changes in volume 4, the thickness of the thrust bearing raceway permissible variation
- 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: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
- What is the function of the flat retaining ring of NUP cylindrical roller bearings with flat retaining rings?Used for more loose transition fit, so that the disassembly and assembly, to play an axial positioning and to bear axial thrust
