The reasons for the emergence of low temperature in Timken cylindrical roller bearings include: not smooth enough or too smooth; The smoothing agent contains publications; Excessive load; Bearing protection; Clearance surplus, low temperature conflict with oil seal, etc.
When the bearing is in an abnormal condition, it will generally go through low temperature. Low temperature is harmless to the smoothing agent in Timken cylindrical roller bearing, and bearing overheating can also be the result of the smoothing agent. Timken Cylindrical Roller Bearing If the bearing is operating temporarily beyond the measurement of 125 ℃, the service life of the outlet bearing will be extended. Therefore, pay attention to the low temperature of the bearing.
Please check Timken cylindrical roller bearings when opening the bearing housing. Besides, check the oil seal regularly. Review the oil seals close to the bearing to ensure that they can prevent hot solids, erosive solids or gases from penetrating into the bearing along the axle. Timken Cylindrical Roller Bearing If the oil seal is worn, replace it as soon as possible.
We should do a good job in the bearing smooth range. If the bearing loses excellent smoothness and accurately blocks sundries and Timken Cylindrical Roller Bearing eczema, the oil seal should not be worn.
In order to prevent Timken cylindrical roller bearing from being damaged during operation, resulting in facility shutdown and loss. Timken Cylindrical Roller Bearing Therefore, the monitoring task should be done well.
In order to prevent the bearing from being scratched during installation, unless appropriate machines are used in the process of installation or assembly, Timken Cylindrical Roller Bearing punch should be used to prevent the thrust load on the bearing, and pay attention to the mutual centering during installation.
The secondary reasons for the scratches in the process of bearing installation are: the inner ring and outer ring of the bearing are skewed during installation and assembly; Timken Cylindrical Roller Bearing Or it may be the emerging charge and collapse load in the process of installation and assembly,
1. Keep the bearing and its surroundings clean;
2. Be careful when using. If the bearing is carelessly impacted, the bearing will be damaged, indentation, fracture and so on;
3. Use appropriate tools;
4. Pay attention to the rust prevention of the bearing, avoid using it in wet places, and wear gloves to prevent sweat;
5. Users should be familiar with bearings;
6. Formulate operation specifications for bearing use;
7. Storage of bearings;
8. Cleaning of bearings and their surroundings;
9. Inspection of dimension and processing quality of installation parts;
10. Installation work;
11. Inspection after installation;
12. Dismantling operation;
13. Maintenance (regular inspection);
14. Lubricant supplement.
Centripetal thrust ball bearing is a precision part, so it is required to be quite cautious in use, that is, it uses high-performance bearing. If it is not used properly, it can not achieve the expected performance effect, and it is easy to damage the bearing. Therefore, pay attention to the following matters when using bearings:
the centripetal thrust ball bearing can obtain a longer life than the traditional calculation, especially under light load. These special operating conditions are the surface damage that may be caused when the rolling surface (track and rolling parts) is effectively separated and limited by a lubricating oil film. In fact, under ideal conditions, the so-called permanent bearing life is possible.
Grease lubrication includes the sealing method of filling grease in the sealed bearing in advance, and the filling grease supply method of filling an appropriate amount of grease in the shell and replenishing or replacing it at regular intervals. In addition, the centralized grease supply mode with pipes connected to each lubrication point is also adopted for the machinery with multiple centripetal thrust ball bearings that need lubrication.
Grease lubrication can be filled with grease for a long time without supplement, and the structure of its sealing device is simple, so it is widely used. Oil lubrication is relatively simple.
