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:Cylindrical roller bearings, in the grease after the operation for a short period of time, the grease was thrown out (thrown to the end cap), resulting in roller and raceway between the lack of grease, lubrication poor. Decomposition found that the roller has round circumferential friction marks, but also on the roll, but compared to the roller is very slight. And there are relatively sound bearings, abnormal sound.Is this phenomenon normal? What if it doesn't work? What was the reason? What's the solution? StopThanks for your help!Assuming the grease is no problem, viscosity, consistency, selection is no problem If exclusion is the problem of grease, what other reasons can this be the case? ?: Normal phenomenon: your choice of grease is too thin, choose a high degree of consistency. 2: mechanical revolution is too fast. 3: Grease adhesion is not high. Three possibilitiesHangzhou Xingang Petrochemical Co., Ltd. specializes in producing and selling grease and lubricating oil. Tip answer

Q:Full use roller bearings: INA full capacity roller bearings have many uses and many applications. Germany FAG bearing group global production of rolling bearings and linear products leading enterprises, not only FAG bearings of good quality, but more importantly, FAG industrial services. In order to extend the life of the railway axle box bearing unit, it is decided that the new FAG axle box bearing unit industry service will be added. We will go to Shanghai FAG bearing China general agent to learn about FAG new axle box bearing units, reprocessing industrial services and other industrial services. The FAG industrial services reprocessing service itself includes thorough cleaning of all bearings, as well as inspection of the dimensions and functions of the entire bearing units. Will re adjust the crankcase clearance, re lubrication SKF bearings, any wear parts will be replaced, if requested by the client, bearing data can also be recorded in the database, for future tracking and review.

Q:The thrust cylindrical roller bearings do not need the bearing seat, and the thrust bearings, shaft rings and seat rings on our unit are all in the bearing seat, often broken. The rotation of the 1. shaft in the bearing seat will not be affected, moreover, the shaft will have radial runout. 2. do not use the bearing seat, usually how to refuel?.Are there any field installation drawings or data on thrust bearings?. Thanks a million!: In general, this kind of bearing does not use the bearing seat

Q:How are the twin row cylindrical roller bearings classified?: Double row cylindrical roller bearings have cylindrical inner bore and conical inner bore (bearing rear code plus K) two structures. This kind of bearing has the advantages of compact structure, large rigidity, large bearing capacity and little deformation after load. It is especially suitable for spindle support of machine tools. The conical inner hole can also play the role of micro adjustment of the clearance, and can simplify the positioning device structure, and is convenient for installation and disassembly.

Q:How much is the axial force of double row cylindrical roller bearings? How is it calculated?: The cylindrical roller bearings have ribs can withstand certain axial force, the axial force for cylindrical but still belongs to the non normal stress, can cause early failure of the bearing, it is generally not given the axial bearing capacity, no formula

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:Is the nu240em cylindrical roller bearing split?: No, nu240em cylindrical roller bearings are integral.Bearing type: cylindrical roller bearingNew model: NU240EMOld model: 32240EHInternal diameter (mm):200Outside diameter (mm):360Width (mm):58

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.

Q:Why are there no double row cylindrical roller bearings in the mechanical design manual?: So under normal circumstances, the bearing bore and the shaft is no gap.But do you mean that the inner ring and the shaft of the bearing are fixed,

Q:Can it be used for axial alignment? Forty-fiveWhat is the function of the flat retaining ring of NUP cylindrical roller bearings with flat retaining rings? Can it be used for axial alignment?How much axial force can I bear then?You are the ZWZ? Can you make a friend?!How much axial force can you bear? Do you have a formula or a recommended value?NUP is needle roller bearings, brothers, I dialed the wrong number:What is the function of the flat retaining ring of the needle roller bearing with flat ring NUP? Can it be used for axial alignment?There seems to be no experts here, all mixed up: Yes, the function of the flat ring is to bear the axial force and be used for axial positioning.
