Product Specifications:
Cylindrical roller and race for line contact bearing. Load capacity is big, mainly bear radial load .
1. Friction coefficient is small, suitable for high speed limit speed close to deep groove ball bearings
2.N and NU type axial movement, can adapt to shaft caused by thermal expansion or installation error and shell the change of relative position, can be used for free end bearing
3. On the shaft or hole of the processing and the demand is higher, bearing outer axis relative deflection after installation to be kept under strict control, so as not to cause contactstress concentration
4. Inner ring or outer ring separable, easy to install and remove

- Q: How are the twin row cylindrical roller bearings classified?
- Classification of double row cylindrical roller bearings:The NN0000 type cylindrical roller bearingsThe bearings are compact in structure and small in deformation under load, so they are especially suitable for the support of the spindle of machine tools. Because of its no outer wall, so you can install the outer ring and the inner ring assembly respectively (with roller and cage), does not limit the axial displacement of the shaft or housing, compared with the single row cylindrical roller bearing with the same radial size, can bear larger radial load.
- Q: How much is the shaft shoulder height of the 81105 cylindrical roller bearings with inner diameter 25mm?
- The purpose of the shoulder shaft is to limit the axial sliding, of course, as the thrust bearing, the main bearing capacity is the axial force, so the shaft shoulder size can be appropriately larger.
- Q: Which column roller bearing brand is good?
- Foreign SKF is better, the domestic is Kazakhstan axis, and then is Taiwan's Rui Rui, you can look at yourself, they recently in the Qingdao market to great influence, you can understand.
- 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: What is the maximum rotational speed of a single row full cylindrical roller bearing?
- FAG single row full cylindrical roller bearingsFAG single row full cylindrical roller bearings can bear large radial loads, and can also bear single direction axial load. Axial positioning can be guaranteed by a symmetrical arrangement of similar bearings. NCF, 29V, NCF, 30V series of bearings have two fixed inner ring, the outer ring has a baffle, they can only bear the direction of the outer edge of the fixed axial load. The NJ23VH series bearings can bear the axial load toward the inside of the inner ring, and their rollers are fixed in the outer ring, even if the inner ring is taken away. The two rings are tight fit, easy installation and disassembly.
- Q: Double row cylindrical roller bearings how to disassemble?
- If it is replaced, use the flame to heat it quickly under the conditions permitted! The inner ring is heated and expanded and removed rapidly; flame cutting is used directly.
- Q: cylindrical roller bearings N210 20Deep groove ball bearings 6120, self-aligning ball bearings 1210, cylindrical roller bearings N210 in the same radial force conditions, the life expectancy of the three levels and how to compare? What is the cause of the high and low?
- In these three bearings, the deep groove ball bearings roll with the bearing outer ring point contact, and the bearing outer ring contact surface is smallest. The self-aligning ball bearing and the outer ring of the bearing are double point contact, and the contact surface is slightly larger than the outer ring of the bearing.
- Q: What are full cylindrical roller bearings?
- Full cylindrical roller bearingCommon cylindrical roller bearings1, single row full cylindrical roller bearingsNCFNJG2 、 double row full cylindrical roller bearingNNCLNNCFNNCNNFTwo, not common full cylindrical roller bearings1, full spherical cylindrical roller bearings2, CARB ring roller bearings
- 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: 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.
