Thus, a good maintenance program might lubricate the bearings frequently but not include any disassembly for cleaning. Cleaning is of little use, because cleaning is expensive yet the bearing is contaminated again as soon as the conveyor resumes operation. Much of this oil flows through passages drilled or cast into the engine block and cylinder heads, escaping through ports directly onto bearings, and squirting elsewhere to provide http://www.bhsbearings.com/product/high-speed-slide-bearings/slide-bearing-for-turbines.html an oil bath.. For example, bearings in the conveyor of a rock crusher are exposed continually to hard abrasive particles.
Bearing life is often much better when the bearing is kept clean and well lubricated. However, many applications make good maintenance difficult. The frequent lubrication, by its nature, provides a limited kind of cleaning action, by displacing older (grit-filled) oil or grease with a fresh charge, which itself collects grit before being displaced by the next cycle.The oiling system inside a modern automotive or truck engine is similar in concept to the lube systems mentioned above, except that oil is pumped continuously. The oil pump simply pumps constantly, and any excess pumped oil continuously escapes through a relief valve back into http://www.bhsbearings.com/product/high-speed-slide-bearings/slide-bearing-for-turbines.html the sump.
Many bearings in high-cycle industrial operations need periodic lubrication and cleaning, and many require occasional adjustment, such as pre-load adjustment, to minimise the effects of wear
