Permawick fibers absorb oil and trap oil, forming a physical/chemical bond between fiber and oil. The result is dramatic - Permawick is 85% oil by weight, 99% oil by volume! It is virtually like filling your bearing reservoir with liquid oil.

The fiber-oil bond has another important feature, the ability to set and control the release rate of oil. By careful selection and processing of fiber, the Permawick material is blended to a uniform rate of release, depending on the means of feeding oil to the journal. NP fiber is used to lubricate sintered bearings, HH and FHH fiber lubricates felt contactors in sleeve bearings.
