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: NSK cylindrical roller bearings EW/EM series of differences and characteristics
- E international is called "reinforced type" load, also means to increase rolling bodyW international is called a steel cageM international is called brass retainerThis can be a question, just ask, for reference only
- Q: How much is the shaft shoulder height of the 81105 cylindrical roller bearings with inner diameter 25mm?
- The purpose of the shoulder shaft is to limit the axial sliding, of course, as the thrust bearing, the main bearing capacity is the axial force, so the shaft shoulder size can be appropriately larger.
- Q: KOYO cylindrical roller bearings, //KOYO cylindrical roller bearings, how to determine the accuracy level?
- Bearing accuracy grade standards for, divided into 0, 6X, 6, 5, 4, 2, six grades.The accuracy of bearings is increased in order of magnitude 0, which is adequate for general 0, but requires 5 or higher accuracy when used in other conditions or situations.In most cases, it is sufficient to apply KOYO bearings (tolerance grade PN) with general dimensional accuracy and rotational accuracy. When higher requirements are required, the bearings require higher levels of accuracy, for example, the spindle axis of the machine toolBearing. In order to achieve higher precision requirements, the standard specifies the tolerance levels of P6, P6X, P5, P4 and P2. KOYO also specified P4S, SP and UP tolerances for some special bearings in accordance with company standards.
- 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?
- The 2 kind of bearing retainer material is mostly copper, and the retainer pin is also copperThere is also a steel retainerImported bearings also have copper and steel
- 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: What kind of material is used for cylindrical roller bearings?
- Ah, you ask what material to do, of course, with the bearing steel do ah. Bearing steel, however, is well distributed. Generally use GL15#
- Q: Is the nu240em cylindrical roller bearing split?
- Cylindrical roller bearings are generally used to bear radial load, compared with deep groove ball bearings of the same size, with larger radial load capacity, speed limit is closer to the deep groove ball bearing, but the processing with the shaft and the bearing shell with high requirements, allow the inner ring and the outer ring axis axis inclination is small (2 degrees -4 two degrees), such as the axis is tilted beyond the limits, contact roller and raceway will worsen, seriously affect the load bearing capacity, reduce the service life of the bearing.
- 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.
- Q: The Russian bearing suffix No. ZST is a cylindrical roller bearing
- Well, you have to write out the whole model. The suffix code is not used to distinguish the bearings, but it helps to explain the structure of the bearings and the material.
