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:How should I find the concentricity of cylindrical roller bearings after installation?
- Any form of assembly, adjustment center is a very troublesome thing, but also in the measuring installation is not very complete, the usual method is to in the base below (or below) thin copper with different thickness, until you feel better, but each installation to re adjust. So, in the machining process, try to use special fixtures and parts drawing in tol and other measures to avoid such a remedy".
- Q:Can you make it clear? I don't understand. Thank you for being here first.
- A rolling body is a short cylinder.The inner ring (or outer ring) of the bearing can be split.
- 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:Thrust cylindrical roller bearings, the main use?
- Our factory uses the bearings of Changzhou Enke Bearing Co., Ltd., they have many kinds of bearings and meet various demands.
- 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:How much is the shaft shoulder height of the 81105 cylindrical roller bearings with inner diameter 25mm?
- The shoulder height (diameter) shall be smaller than the big diameter of the bearing (less than 42), mainly for easy unloading.
- 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:How to calculate the clearance of bearings, such as 23226 double row cylindrical roller bearings
- First of all for the bearing clearance calculation is a very complicated problem, because the bearing structure of different types, and the usage of different materials, the temperature of different factors such as the clearance is different, and because of the different structure types and some bearing bearing clearance is divided into radial clearance and axial clearance; also need to pay attention to the bearing clearance is usually divided into the following 1. conditions, clearance before installation, usually refers to the bearing manufacturers factory according to the standard to determine the clearance of bearing clearance. 2., after the installation clearance, because the bearing inner ring and the shaft is interference fit, when the bearings installed on the shaft, its inner ring will be as the amount of interference and expansion, resulting in smaller clearance of bearings. 3. clearance work, because the bearing is affected by load and rotating friction in the work, the temperature will gradually increase, will cause the bearing inner ring further expansion, which will make further changes in bearing clearance. However, the main clearance of the bearing is the largest (minimum) diameter of the raceway of the outer race of the bearing, the largest (minimum) diameter of the rolling body and the largest (smallest) diameter of the raceway of the inner race. For example, cylindrical roller bearings, its largest clearance = outer raceway raceway, maximum diameter of -2* roller minimum diameter - inner raceway minimum diameter derived, and conversely, for the smallest clearance. The average user of bearings actually doesn't need to know that.The other 23226 models should be the spherical roller bearing, not double row cylindrical roller bearing.I hope my answer will be of some help to you!

- Q:Why cylindrical roller bearings can not bear axial load?.
- The thrust bearing retainer plate and two pieces of circular hole of the ball and the ball hole and shaft wear in the park, circular plate, steel ball track between two plate, shaft and the bearing seat of the top plate in the round two sides, in addition to the track groove, it is not binding the radial direction, so it cannot withstand the radial load.The radial bearing by the size of the two steel ring, steel ball size between steel ring, steel ring diameter fixed by a bearing seat, shaft mounted on a small steel ring, binding only in the radial direction and axial direction of the load is not binding, so it cannot withstand the axial diameter.
