 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.

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: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 are the differences between cylindrical roller bearings nu208m and nu208em?
E means "reinforced", "rolling", "thickening", "change", "change".. Hope to adopt!!
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: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.
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:Cylindrical roller bearings standard 10
This could be a car only bearing! NSK sample short column can not find the corresponding model!
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:Attention problems of cylindrical roller bearings
1. The installation of bearings must be carried out in a dry, clean environment. Before installation, the machined surface of the shaft and shell, the shoulder end, the groove and the joint surface shall be carefully inspected. All mating surfaces must be carefully cleaned and removed, and the cast surface must be clean. 2, before the installation of bearings, should be cleaned with gasoline or kerosene, dry after use, and ensure good lubrication, bearings generally grease lubrication, oil lubrication can also be used. Grease lubrication, grease, anti rust, extreme pressure and other excellent greases should be used. Grease filling capacity for bearings and bearing box volume of 30%-60%, should not be too much. Double row tapered roller bearing and water pump shaft bearing with sealing structure have been filled with grease, which can be used directly by users and can not be cleaned again. 3, bearing installation, must be applied equally in the circumference of ferrule end face pressure to press into the ring, and may not directly tap bearing end face to the top tool, so as not to damage the bearing. Small amount of interference in the case, at room temperature can be used to suppress sleeve bearing ring face, beating with a hammer sleeve, the sleeve will be pressed into the ring balance. If installed in large quantities, use hydraulic press. When pressing, the outer end surface of the outer ring and the outer shoulder of the shell face shall be ensured, and the inner ring end face is tightly pressed with the shoulder end of the shaft platform, and no gap is allowed.
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 cage
