Bearings lubed-for-life

Traditionally, greases and oils have been used to lubricate ball and roller bearings. These lubricants can be messy, causing significant housekeeping problems and requiring periodic maintenance to replenish the lubricant. Solid lubricants, such as microporous polymeric lubricants (MPLs), can significantly reduce or eliminate these problems.
