Specification of rolling mill bearings:
Metallurgical Rolling Mill
Require high precision, large rated moving load, and high maximum rotation speed. By adopting the new technology of material processing, for instance, the Bainite Treatment, CNBM has successfully manufactured bearings of long service life that are highly fatigue resistant and impact resistant. The high and stable product quality has helped CNBM gain good reputation among more than 100 large and medium-sized steel enterprises all over China.
They types of bearings made by CNBM for the metallurgical rolling mills are: single-row, double-row, triple-row, quadri-row cylindrical roller bearings, deep groove ball bearings, single-row and double-row angular contact bearings, four-point contact ball bearings, single-row and double-row tapered roller bearings, fully-loaded cylindrical roller bearings(roller wheel bearings), and non-standard bearings of large sizes.
- Q: Why is the cage of tapered roller bearings loose?
- You can come up with the relevant standards, must belong to the bearing standard parts, as long as you meet the standard requirements of the bearing can be spread!
- Q: Taper roller bearings are used on my motor. Serious damage occurred during use. Please help me analyze the possible causes of damage! Thank you
- To LZ: 1 it is recommended that the radial force and the rated load of the bearing be compared to determine whether the radial force is too large (if there is axial force, it needs to be synthesized as equivalent load, and then compare.) In 2 section, you basically is the middle of the two row tapered bearing ring and then as a double row tapered to use (not in general, so natural clearance installed back to back) without gasket or nut to adjust, this is a very good idea.
- Q: What is the size of tapered roller bearings 352214?
- Bearing type: tapered roller bearingNew model: 352214Old model: 97514EInternal diameter (mm):70Outside diameter (mm):125Width (mm):75
- Q: What are the conditions for the normal and reverse loading of tapered roller bearings?
- When the transmission parts between the two bearings, the formal wear of the pressure center to reduce the distance, and help to improve the rigidity of the shaft, the reverse is the opposite. Therefore, two contact ball bearing or tapered roller bearing suits and reverse installation should be based on the transmission parts (gear, worm) considering the structure and the axis. And choose to use.
- Q: Is the tapered roller bearing so correct?
- Tapered roller bearingTapered roller bearings are designed for the inner ring, outer ring raceway and roller cone vertex on the central axis of the bearing, radial load acting on the bearing, axial force is generated. Therefore, it is necessary to use the 2 bearings for use, or as double pairs of bearings, double row bearings. Combination and double row tapered roller bearings, when radial loads act on tapered roller bearings
- Q: How does the roller of tapered roller bearings fit in?
- Tapered roller bearings itself can be broken down, and new (or old) bearings are cleaned and decomposed. So do not worry, carefully installed in accordance with the original installation order on the line, and if it does not meet the installation order, the installation of this bearing is not go on.
- Q: Tapered roller bearing: Bearing expert why burned or locked
- 1, improper choice of bearing clearance.For example: C3 group should be selected for clearance, and the actual use of ordinary group clearance. Because when the bearings work will continue to accumulate heat, shaft diameter and inner ring and outer ring rolling body will swell, because good radiating condition of expansion is relatively small, the whole bearing clearance becomes small, or even negative clearance larger.At this time, stress increases between the body and the rolling roller pressure, lubrication conditions decreased, there will be the phenomenon of boundary lubrication or even local steel on steel friction, so the temperature continues to rise, the base oil in lubricating grease evaporation, so lead to vicious spiral bearing overheating burned, rolling annealing into blue black color, then bearing the friction increasing roller holder to stop COLLOPSE bearing lock.
- Q: What does "tapered roller bearing" suffix "A" mean?
- Tapered roller bearing suffix AA - angular contact ball bearings with a contact angle of 30 degreesA5 - angular contact ball bearings with a contact angle of 25 degrees
- Q: What are the general uses of tapered roller bearings?
- At the time of greater radial load and axial load
- Q: Tapered roller bearings, 70 in diameter, please tell me the model number
- What about outside diameter (D) and width (B)? You didn't say?.Following are all series of codes and sizes for tapered roller bearings (single column and double row).
