Product Specifications:
cylindrical roller bearing , 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 contact stress 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: Cylindrical roller bearings NUP2311E mounting dimensions: Da (max): 69Da (min): 64DB (min): 72DC (min): 80Da (max): 111What are the specific meanings of these dimensions? Thank you, master
- I don't know what you mean. The size of NUP2311E is: inside diameter, 55mm, outside diameter, 120mm height: 43
- 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 are the components of cylindrical roller bearings?
- Compared with the deep groove ball bearings of the same size, this kind of bearing has larger radial load capacity, and is also suitable for high-speed rotation from the structure.
- 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: 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!
- Cylindrical roller bearings themselves require that the applied speed can not be too high, especially in short axis applications
- 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: 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: Cylindrical roller and bearing outer ring processing is sheet metal forming?
- Sheet metal forming? You think too simple. Do you know that a key technical parameter of a machine part is called tolerance? The inner and outer rings and roller rolling bearings (ball, roller) have strict tolerance requirements, but also requires a very high hardness and abrasion resistance, the general is the use of special alloy steel, rolling (usually hot) heat treatment after forming, after precision machining (turning, grinding etc.) after finished product.
- Q: Why should the main shaft be coupled with double row cylindrical roller bearings?
- Because double row cylindrical roller bearings with high carrying capacity, high precision, separation, easy installation and disassembly, mainly used in lathes, milling machines, machining centers and other high-precision machine tool spindle. Hope to be of help to you.
