Q:Seek expert help: cylindrical roller bearings, grease injection, the operation of a short period of time, grease is thrown out, what is the reason, how to solve? Two hundred
If the grease is dry, adhesion is not good, some of the high temperature grease stored for a long time will be dry, it will apply to the bearing is easy to get rid of, especially now the winter oil solidification, the lubrication effect is less. It is recommended to use low temperature grease in winter or add some oil to dilute it. The best way is to change the grade of grease. If the inner ring of the bearing can be removed, grease can be filled from it.
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:Radial roller bearingWhat do you mean by a roller, a column or something else?
A rolling body is a short cylinder.The inner ring (or outer ring) of the bearing can be split.
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:Cylindrical roller bearings, mounting dimensions, specific meaning? Twenty
Da means shoulder diameter, that is to say, the maximum shoulder size is 69mm, and the minimum is 64mm
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. Our factory uses the bearings of Changzhou Enke Bearing Co., Ltd., they have many kinds of bearings and meet various demands.
Q:Double row cylindrical roller bearings how to disassemble?
The inner ring is heated and expanded and removed rapidly; flame cutting is used directly.
Q:Can cylindrical roller bearings bear high temperature?
Bearing is not high temperature grease is not high temperature, a grease temperature does not exceed 120 degrees, high temperature will lead to bearing lubrication performance, unable to work, in fact, the bearing itself can be high temperature resistant.
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
Q:Full use cylindrical roller bearings, uses and advantages?
Otherwise, due to lack of lubrication and high-speed operation will cause more wear and tear. I am a bearing
