Bearings are used frequently in customers reflected bearing vibration temperature are abnormal. According to bearing technical explanation of factors that contribute to this area of the Group has the following several points: KOYO bearings temperature climbing bearing speed increases. And 1-2 hours after the temperature reaches the stable running stability. Bearing temperature main determining factors are many, such as speed, lubricants, load, intrusion of foreign bodies such as reason. If you find the above operation must be stopped, to take the necessary measures.
Customers are advised to use heat sensors monitor the operating temperature of the bearing over time. Bearing temperature in more than 125 ° c long-term continuous transfers reduce the bearing life. KOYO bearings caused by high temperature causes include: inadequate or excessive lubrication lubrication, lubricant. Contains impurities, excessive load, k ring of bearing damage, inadequate clearance, and so on. If not found and disposed of in a timely manner will result in bearing scrap. Bearing temperature monitoring is essential for the continuity of both measuring bearing itself or other important parts. If operating conditions do not change case, any temperature changes may have occurred at fault.
KOYO bearings if abnormal vibration generated in the running and is easy to produce damage. Including fretting, indentation damage, damage, such as cracked, irregular wear. Therefore, through the vibration of bearing vibration Measurer to measure out the size of measured values from bearing conditions of use or the sensor installation locations and different, we recommend that the customer's prior record of value during normal operation of the machine to facilitate comparative analysis.
1: observation
Bearing if are good of lubrication and correctly of barrier debris and the humidity, said oil seal should no wear. However, best in open bearing box Shi, to Visual check KOYO 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 infiltrated bearing. protection ring and the maze oil seal should James Shang grease to ensure its maximum of protection role. oil seal if has wear should as soon as possible replaced.
2: listen to the
Using the auditory identification of correct bearing operation, this is the best method. KOYO bearings if it is in good operating condition will issue a low Purring sound. If the high-pitched hissing sound, squeaking sound and other irregular sounds, usually means that the operation of the bearing is in a bad situation.
