Oil: Both petroleum based and synthetic oils are available. Examples of synthetic oils are silicone, diesters, PAO’s, and fluorinated compounds. Bearings lubricated with oil will exhibit less start up and running torque and have higher speed capability. Oils are subject to evaporative losses so there service life in a bearing is less than grease.
Get PriceRegular re-greasing of these bearings and their housings purges the contaminated grease out of the bearing housings. It is important to remember that re-lubrication should be done when grease in the bearing is still good. Re-greasing intervals, that will always provide the proper amount of oil to the bearings, cannot always be accurately predicted.
