TIMKEN bearings are precision parts and require a very cautious attitude when used. That is, the use of high-performance bearings can not achieve the expected performance if not used properly, and it is easy to damage the outer spherical bearings. Most of the bearings are damaged for many reasons - beyond the original estimated load, non-effective seals, too tight bearing clearance caused by too small bearing clearance. Any of these factors have their particular type of damage and leave a special mark of damage.
Therefore, inspection of damaged bearings can be found in most cases. In general, one-third of TIMKEN bearing damage is caused by fatigue damage, and the other third is due to poor lubrication. The other third is due to contaminants entering the outer spherical bearing or improperly installed.
Therefore, what we want to talk about is how to protect it and extend its service life. Who is unwilling to make the bearing wear-resistant and durable? Unless your nerves have problems (hehe), you should pay attention to the following matters when using bearings:
If the bearing is used improperly during operation, it will cause a series of problems, so we should pay attention to these problems in order to find the problem and solve the problem in time to ensure the normal use of the bearing. Under normal circumstances, the outer spherical bearing should pay attention to the following three major matters during operation.
First, check the condition of the running machine and monitor it to avoid equipment downtime.
Second, if the TIMKEN bearing is under-lubricated or over-lubricated, the lubricant contains magazines, the load is too large, the outer spherical bearing is damaged, the gap is insufficient, and the high-temperature friction generated by the oil seal is the same.
High temperatures often indicate that the bearing is in an abnormal condition. High temperatures are also detrimental to the lubricant in the bearing. Sometimes bearing overheating can be attributed to the bearing's lubricant. If the bearing is operated for longer than 125 degrees Celsius, it will reduce bearing life.
Third, it is best to check the TIMKEN bearing and periodically check the oil seal when opening the bearing housing. Check the condition of the oil seal near the bearing to ensure that they are sufficient to prevent hot liquid or corrosive liquid or gas from penetrating into the outer spherical bearing along the shaft. If the bearing is well lubricated and properly blocks debris and moisture, the oil seal should be absent. Wear. If the oil seal has worn out, it should be replaced as soon as possible.
