Choosing a suitable lubrication system and high-quality lubricant is crucial. A lubricating oil film separates contacting oil surfaces and provides essential protection against corrosion and wear. Therefore, a lubricating oil film is indispensable for the normal operation of all rotating or reciprocating parts, especially bearings and gears. In splash or circulating lubrication systems, the oil film also transfers heat.
Inadequate lubrication frequently leads to unnecessary downtime and equipment deterioration. Insufficient lubrication results in increased wear and temperature rise, causing excessive wear and/or premature bearing failure and damage. Over-lubrication, especially in high-speed equipment, generates excessive heat due to oil turbulence, causing chemical degradation of the lubricating oil and also leading to bearing damage.
Proper lubrication and regular maintenance can prevent bearing damage caused by lubrication problems. To ensure proper lubrication, the following should be observed: Follow the user guidelines provided by the equipment manufacturer for each piece of equipment; when adding grease, fill it between the rolling parts of the bearing and the housing (or retainer ring) to ensure sufficient grease penetration and adequate lubrication of critical raceway surfaces; pay attention to when bearings should be greased; monitor equipment indicators to detect signs of problems as early as possible, such as temperature fluctuations and/or abnormally high temperatures; pay attention to equipment noise or abnormal vibration; observe for lubricating oil leaks; and regularly sample the lubricating oil to check for contamination.
