SKF bearing vibration temperature anomalies of the elimination method

SKF bearings are used in the process of bearing vibration temperature is abnormal. Recommended by thermal sensors monitoring of SKF bearing temperature at any time. If bearings in more than 125 ℃ temperature long-term continuous transfers reduce bearing life. Cause of the bearing high temperature including: lubrication is insufficient or excessive lubrication, lubricant. Contains impurities, excessive load, bearing loss rings, insufficient clearances, and so on. If not found and disposed of in a timely manner will result in SKF bearing scrap. Therefore continuity bearing temperature monitoring is necessary, whether measured or other important parts of the bearing itself. If operating conditions do not change case, any temperature changes may have occurred at fault.
Abnormal vibration generated in the bearing if you are running and is easy to produce damage. Specifically fretting damage, cracks, indentation damage phenomena such as damage, abnormal wear. So by SKF bearing vibration Measurer to measure the size of the vibration, the measured value due to conditions of use of SKF bearings or sensor installation locations vary, we recommend that customers with the prior record numerical machine functioning to facilitate comparative analysis.
The first: to observe the law
SKF bearing if are good of lubrication and correct of barrier debris and the moisture, said oil seal should no wear. However, best in open bearing box Shi, to Visual check bearing and regularly sexual check oil seal. check near bearing Department oil seal of situation to ensure they enough to prevent hot liquid or corrosion liquid or gas along axis infiltration bearing. protection ring and the maze oil seal should coated Shang oil to ensure its maximum of protection role. oil seal if has wear should as soon as possible replaced.
Second: listening
Using the hearing to identify SKF bearing is functioning correctly, this is the best method. If the bearing is in good running condition will issue a low Purring sound. sound high-pitched hiss hiss, squeaking sound and other irregular sounds, it usually means that the operation of bearings is in a bad situation.

Previous: From Visual inspection of INA bearing quality considerations
Next: After the operation of heating problem of SKF bearings checks
