First, the lubrication is key. Select the appropriate lubrication systems and high quality lubricant. Lubricating oil film will touch each other because of the bearing oil film separates the surface and provide the necessary protection against corrosion and wear, so all rotating or reciprocating parts, particularly bearings and gears if normal operation, lubrication film is indispensable. As for the splash lubrication or circulating lubrication system, oil film can pass heat. Factories often unnecessary downtime due to improper lubrication and deterioration in device status. Oil supply shortage leads to increased wear and temperatures rise, causing excessive wear and early failure and/or bearing damage. Excessive lubrication, particularly fast-moving device, because oil stir arising excessive heat, chemical degradation of lubricating oils, can also cause damage to the bearings.
Correct lubrication, regular maintenance to avoid bearing damage due to lubrication. Ensure a reasonable lubrication should be done:
• Follow the device manufacturers to set usage guidelines for each device;
• Increase when the grease should be filled into SKF bearings rolling elements and shell (or retainer), to ensure enough grease to enter key full lubrication of Raceway surface;
• Should pay attention to when greasing of the bearings (Re-lubrication);
• Monitoring device for indicating instrument, provide an early warning signs of problems such as temperature fluctuations and/or abnormally high temperature;
• The attention device abnormal noise or vibration;
• Observation of lubricating oil leakage;
• Regularly samples the Lube, and see whether the pollution.
Second, if you want to improve bearing performance, reasonable adjustment is very important. When the Assembly or installation, such as bearing internal clearance is too large or too small, or, in some cases, the preload is too high, which can lead to early damage and reduced bearing life. Subject to downtime and costly repairs and maintenance, FAG bearings Assembly and installation may also have more negative effects that affect the functioning of other parts and shorten its service life.
According to the device manufacturer′s user manual for Assembly, installation and regular maintenance is the best way to prevent problems. If time is tight, and devices can be adjusted forward or remove the gasket, to correct loose tapered roller bearing unit. The other hand, NSK bearings are adjusted too tight may result in overheating damage, had to replace the bearings. Assembly install the bearing operation must be accurate, repeatable, and can verify after the installation is complete. Must also take into account other parts parameters to optimize system performance.
In addition, in accordance with the requirements of the OEM to use the device, set appropriate predictive maintenance items, such as the monitoring of oil or grease, which should include fault root cause analysis. In this way, even if the device in question, their uptime can also be considerably extended.
Proper lubrication and maintenance are critical, the correct installation and use is also indispensable, and full use of the existing State monitoring equipment, escorts. Failure to follow installation and maintenance requirements will result in equipment failure, pose a major security risk.
