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: Which column roller bearing brand is good?
- Foreign SKF is better, the domestic is Kazakhstan axis, and then is Taiwan's Rui Rui, you can look at yourself, they recently in the Qingdao market to great influence, you can understand.
- 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: 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: 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 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: Is the roller bearing and the bearing chamber movable in the tapered rotor motor?
- E in cylindrical roller bearing is the meaning of improving internal cage design, similar to the SKF cylindrical roller bearing EC form, this type of bearing than without E, is to strengthen the design, the roller is filled more larger to increase the load. From the load point of view, it is better to choose E.
- 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..Imported bearings are basically the same as those made in China. There are copper, steel, alloy and so on.
- 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: Cylindrical roller bearings, in the grease after the operation for a short period of time, the grease was thrown out (thrown to the end cap), resulting in roller and raceway between the lack of grease, lubrication poor. Decomposition found that the roller has round circumferential friction marks, but also on the roll, but compared to the roller is very slight. And there are relatively sound bearings, abnormal sound.Is this phenomenon normal? What if it doesn't work? What was the reason? What's the solution? StopThanks for your help!Assuming the grease is no problem, viscosity, consistency, selection is no problem If exclusion is the problem of grease, what other reasons can this be the case? ?
- The higher the speed, the greater the centrifugal force, this point should be mastered. If the grease of good quality, from the bearing chamber to consider the change of the bearing chamber space, the sides of the bearing sealed by using injection nozzle gun grease can improve the lubrication condition.
- Q: Full use roller bearings
- The service is applied to all axle box bearings, including FAG cylindrical roller bearings, spherical bearings and tapered roller NSK bearings. In addition, FAG industry services also provide support to customers in the rail industry who introduce maintenance management systems. INA bearing agent Chinese by helping clients improve internal maintenance procedures, F IS can enhance the data exchange between various departments, and clearly useless procedures, such as entry in IT system and database in different kinds of data. This reduces the cost of raw material management and speeds up maintenance activities. NSK it is very important for the effective maintenance management to install the bearing units rapidly and effectively in china. At the same time, the F IS offers a range of energy saving bearing heaters. Including the FAG Powertimken series induction heater, to enable customers to reduce the installation time of bearing, NSK bearings so as to shorten the downtime, instead of using the traditional heating method (oil bath heating stove, or board). FAG is a research and development partner and supplier of the world's leading Boeing 787 manufacturer. The quality, reliability and efficiency of Schaeffler's aviation bearings, INA bearings, price fits, and performance in extreme conditions, the INA bearing agent provides support for the international space navigation corporation. FAG's bearing technology is used on almost all modern aircraft.
