 Cylindrical Roller Bearing Introduction  

    Rolling body is cylindrical roller bearings - Radial. Cylindrical roller bearings internal structure of the roller was 90 ° perpendicular cross arrangement (which is also cross roller bearings origin of the name), equipped with a gap between the roller cage or spacers can prevent tilting roller or rollers mutual ground between the police, effectively preventing the increase in rotational torque.

    Cylindrical roller and raceway for the line contact bearings. Load capacity, the main radial load. Rolling ring wall friction is small, suitable for high-speed rotation. According to ring without ribs, can be divided NU, NJ, NUP, N, NF and other single row cylindrical roller bearings, and NNU, NN and other double row cylindrical roller bearings. The bearing is the inner, outer separable structure.

    Inner or outer wall of the cylindrical roller bearings, the inner and outer ring can be relative to the axial movement, so you can use as a free end bearings. On either side of the inner and outer ring of a double-wall, the other side of the ring has a single wall of the cylindrical roller bearings that can withstand a certain degree of axial load direction. General use of steel stamping cage, or copper alloy solid cage. But there are also some use of polyamide forming cage.

Q:What is the difference between the pre assembly method of double row cylindrical roller bearings and angular contact ball bearings?
The latter is mainly used as a precision screw shaft for the radial motion and axial runout requirements are very strict, generally used when they are two back-to-back, when pre tightening have strict requirements, general requirements for the radial motion and axial runout should not exceed 5 per thousand mm.
Q:What is the maximum rotational speed of a single row full cylindrical roller bearing?
FAG double row full cylindrical roller bearingsFAG double row full roller cylindrical roller bearings can withstand the radial load and axial load, but also can withstand overturning moment, so they are often used as fixed bearings. The outer ring of the NNC 49V series bearing has a lubricating tank and a number of lubricating holes, which can also be lubricated in the shaft during operation. The NNF50B.2LS.V and NNF50C.2LS.V series of bearings are sealed in both ends, and the seals are filled with grease. With better service conditions, the grease can reach the working life of the bearing. Lubrication can be carried out by lubricating grooves and lubricating holes on the outer ring. If the same number of bearings are mounted on one shaft, the outer ring can vary in speed because the outer ring is narrower than the inner race. The utility model is suitable for a pulley mechanism, so that the pulley can be easily fixed on the outer ring of the bearing, and both ends of the outer ring of the bearing can be provided with an annular groove with an elastic retaining ring.
Q:Can the 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:Attention problems of cylindrical roller bearings
High temperatures often indicate that cylindrical roller bearings are in exceptional condition. High temperature is also harmful to bearing lubricants. Sometimes the bearing is overheated and can be attributed to the lubricant in the bearing. If the bearings are longer than the temperature of 125 degrees, even the transfer will reduce the bearing life. The causes of high temperature bearings include: insufficient lubrication or excessive lubrication, impurities in the bearing raceway, extreme high speed, long term overload operation of bearings, etc..
Q:Radial roller bearingWhat do you mean by a roller, a column or something else?
Oh, My God!!! Do you understand the bearings in this way?! What is called "roller" means that the rolling column is cylindrical and similar to cylindrical shape, such as short cylindrical, long cylindrical, tapered roller, spherical roller, etc.." This kind of statement should be listed as the promotion answer!!! Absurd! Laughable! !!The standard answer is: Bearings in accordance with the direction of force, divided into radial bearings and thrust bearings, in simple terms, if the main force to bear the axial thrust bearings, thrust bearings; otherwise, that is, radial bearings. As for radial roller bearings, simply speaking, it is the roller bearings that mainly bear radial forces. It's so simple, there's so much nonsense!!!
Q:Does the thrust cylindrical roller bearing need a bearing seat?. Five
Hello, I have sent a message to your mailbox, I hope you can help! Have problems you can contact us directly, Beijing Sheng Yi Huitian Electromechanical Equipment Co. Ltd
Q:What is called a semi convex roller, a fully convex roller, a logarithmic curve roller?
The convex roller refers to the basic cylindrical or conical roller with a continuous micro convex radian in the plane containing the roller axis, and the logarithmic curve roller is also a convex roller, which belongs to a full convex roller;Convexity roller refers to the plane containing the axis of roller in the outer surface of a continuous convex curved basic cylindrical or conical roller, roller is logarithmic curve convexity roller, roller is all convex; convexity roller refers to the plane containing the axis of roller in the outer surface of a continuous convex curved basic cylinder or conical roller,The logarithmic curve roller is also a convex roller, which belongs to a full convex roller; a modified roller refers to a roller that has a slightly modified diameter at the end of the outer surface to prevent the contact between the roller and the raceway.
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:What is the limit speed and rated dynamic load of NSK full M40-19g cylindrical roller bearings, HTF?
NSK bearing type suffix solution of NSK bearing type by the basic code, prefix and post code, the basic code bearing series (including type) diameter and contact angle; pre code specific bearing; post code structure shape, bearing size, material, seal, retainer, clearance, heat tolerance processing, lubrication, change and other technical requirements, in addition to the basic code added after bearing code. NSK bearing model prefix F - deep groove ball bearing with flange outer ring (for D less than 10 mm), for example: F605. HR - high load tapered roller bearings, for example: HR30207J. MF - Flanged, outer race, deep groove ball bearings of specified sizes (D less than 10 mm), MF52. MR - deep groove ball bearings of specific size (for D less than 10 mm), for example: MR31. NSK bearing type rear code (1) internal structure A - internal design and standard different bearings. A - angular contact ball bearings with a contact angle of 30 degrees. A5 - angular contact ball bearings with a contact angle of 25 degrees. B - angular contact ball bearings with a contact angle of 40 degrees. C - angular contact ball bearings with a contact angle of 15 degrees. C - tapered roller bearings with a contact angle of 20 degrees.
Q:Gb/t283 cylindrical roller bearing age number?
