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: Why are cylindrical roller bearings suitable for traveling support?: Cylindrical roller bearings without inner sides of the inner ring or outer ring, whose inner and outer rings can be moved relative to the axial direction, so they can be used as free end bearings.

Q: How much is the shaft shoulder height of the 81105 cylindrical roller bearings with inner diameter 25mm?: The shoulder height (diameter) shall be smaller than the big diameter of the bearing (less than 42), mainly for easy unloading.

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: For bearing type, no outer ring single row cylindrical roller bearings, bore 40, thickness 21, roller diameter 8, roller length 12: This is the outer ring and the inner ring can be separated, the bearings in the country can be produced, imported bearings are sold.Another model is up to your standard,Cylindrical roller bearings SL183008Semi position bearing, full cylindrical roller, dimension series 30M 0,31 kgqualityCr 66000, NBasic rated dynamic load, radialC0r 67000, NBasic rated static load radialCur 11200, NFatigue limit load, radialNG 6300, 1/minLimit speedNB 4300, 1/minReference speed

Q: How should I find the concentricity of cylindrical roller bearings after installation?: Any form of assembly, adjustment center is a very troublesome thing, but also in the measuring installation is not very complete, the usual method is to in the base below (or below) thin copper with different thickness, until you feel better, but each installation to re adjust.

Q: What kind of material is used for cylindrical roller bearings?: Products can be widely used in automobiles, motors, construction machinery, mining machinery, machine tools, metallurgy, textile, food, chemical and other enterprises. Our factory has Wuxi city Qikai bearing roller Co. Ltd.

Q: Is the nu240em cylindrical roller bearing split?: Therefore, such bearings need to be installed in the axial load bearing the main components, only at the same time using other types of bearings to withstand axial load on the premise that can be used.

Q: The Russian bearing suffix No. ZST is a cylindrical roller bearing: The suffix code is not used to distinguish the bearings, but it helps to explain the structure of the bearings and the material.

Q: Thrust cylindrical roller bearings, the main use?: Thrust cylindrical roller bearings, the main use? Thrust cylindrical roller bearings are mainly used in oil rigs, iron, steel, machinery and so on.

Q: Cylindrical roller and bearing outer ring processing is sheet metal forming?: Rolling bearings are made by special bearing factories and manufactured by precision special machine tools. It is a highly specialized field in mechanical manufacture. Precision bearings are the key parts to determine the accuracy and operation of the machine. At present, China mainly relies on imports (such as Japan NSK bearings) in high precision bearings.
