An oil's viscosity is correlative to the film thickness it can create. This thickness is crucial to the separation of the rolling and sliding elements in a bearing. Bearings in some applications use oil, but grease …
The lubrication methods available for bearings on a machine tool include grease lubrication, oil mist lubrication, air-oil lubrication, and jet lubrication. Each method has unique advantages. Therefore, a lubricating system should be selected that best suits the lubrication requirements. Tables 7.1 and 7.2 summarize the features of various
increasing total plant productivity. The size range of the OK mill includes 3, 4 and 6 roller mills and includes the largest VRM sizes available with installed power over 11,500 kW.

It's crucial to protect their quality in order to keep the mills fully functioning. In both hot and cold steel mill production, high-demulsibility lubricant is used for backup …
The lubricant is falling on the roller surface and rail without entering between the bushing and roller, and between the roller and link plate. Select the appropriate lubricant and lubrication method. The bushing and roller have rusted together. Select the appropriate specifications (RT, etc.). The inner plate is moving sideward.
Mistake 2 – Over and under Lubrication. The second mistake we must avoid is adding too much, or not enough grease. Too much grease builds pressure, pushing the rolling elements through the fluid film and against the outer race. The bearing now has to work much harder to push the rolling elements through a mud bog of grease.
Lubrication systems Prior to performing any maintenance work on the lubrication systems, read the data and safety data sheet from the lubricant supplier. Before …

The oil supply units for our vertical roller mill gear units and drive systems includes low-pressure pumps to feed bearings and gears with filtered and cooled lubrication oil. High-pressure pumps supply the oil for the thrust bearing from a separate compartment of the tank filled with chilled and filtered oil from the low-pressure section.
With oil-air lubrication systems, many oil types are suitable. Oils with a viscosity of 40 to 100 mm 2 /s at 40 °C (105 °F) are typically used as are oils with EP additives which are preferable, especially for roller bearings. Oils with a viscosity of 10 to 15 mm 2 /s at 40 °C (105 °F) are typically used for oil jet lubrication, whereas oil ...

12/22/20 #3775. I'm not an expert on this, however it looks like normal ware-tare of metal against metal. If the tuner is working OK, I would just give it a good cleaning and continue using it. I would also maybe consider purchasing a spare roller inductor so when it does finally fail I would have a replacement.
