| Why Oil Levels can be Deceptive |
|
You can get false oil levels in hung centrifugal pumps if the case is not vented. When the pump is online and the oil heats up, it builds up internal pressure in the headspace that can cause the oil level to rise in the case. (A.C. Sinitiere, Enterprise Products)

| Oil filters can extend the life of machines by removing harmful particles before they can cause surface degradation of the lubricated components. Perhaps the most crucial attribute of any filter is the ability to trap and hold dirt. This is known as the dirt-holding capacity of the filter. Learn the factors that contribute to how well filters hold the contaminants they catch as well as other things to keep in mind when selecting an oil filter. |

GET THE ANSWER
From "Grease Lubrication in Rolling Bearings":
Roller bearings require a softer grease than ball bearings (on a horizontal shaft). Angular contact ball bearings pump grease through the bearing from the small inner ring diameter side ("low side") to the larger inner ring diameter side ("high side"). In order to prevent this, ideally a stiff grease is preferred on the "low side" and a softer grease on the "high side." Vertical shaft applications require a stiffer grease to prevent grease falling into the bearing. |
