How long is the general life of the bearing

First of all, lubrication is the key

Choose a suitable lubrication system and high-quality lubricants. The lubricating oil film separates the oil film surfaces that are in contact with each other due to the load bearing and provides the necessary protection against corrosion and wear. Therefore, for all rotating or reciprocating parts, especially bearings and gears, if normal operation is required, the lubricating oil film is indispensable lack. If it is splash lubrication or circulating lubrication system, the oil film can also transfer heat.

Factories often experience unnecessary shutdowns and deterioration of equipment due to improper lubrication. Insufficient oil supply can lead to increased wear and temperature rise, resulting in excessive wear and/or early bearing failure and damage. Excessive lubrication, especially high-speed equipment, will generate excessive heat due to oil agitation, chemically degrade the lubricating oil, and cause bearing damage.

Correct lubrication and regular maintenance can avoid bearing damage caused by lubrication problems. To ensure reasonable lubrication:

Follow the instructions set by the device manufacturer for each device;

When adding grease, it should be filled between the rolling parts of the bearing and the housing (or retainer) to ensure that sufficient grease enters and the surface of the key raceway is fully lubricated;

Pay attention to when the bearings should be greased;

The indicator of the monitoring equipment to find signs of problems as early as possible, such as temperature fluctuations and/or abnormal high temperatures;

Pay attention to equipment noise or abnormal vibration;

Observe lubricating oil leakage;

Regularly sample the lubricating oil and check for contamination.

Secondly, reasonable adjustments are very important

During assembly or installation, if the internal clearance of the bearing is too large or too small, or in some cases, the preload is too high, which may cause early damage and shorten the life of the bearing. In addition to causing downtime and expensive repairs, improper bearing assembly and installation may also have more negative effects, such as affecting the operation of other parts and shortening their service life, etc.
