  • Sealing Options for Self-Lubricating Bearings
    contaminates. This is a result of the inability of the bearing surface to ingest the particulate. Self-lubricated bearing manufactures typically design bearing liners that are soft enough to ingest contaminants. Each manufacturer of this type of bearing uses a different construction to try to best solve
  • Bearing Wear
    and self-lubricated bearings wear much faster than fluid-film bearings. Self-lubricating plastic bearings wear at higher rates than boundary-lubricated, metal-alloy bearings. In reciprocating load application, babbitts are subject to fatigue damage in which pieces of the babbitt metal spall out of the surface
  • Why are Rod End and Spherical Bearings Teflon-lined?
    A PTFE (Du Pont trademarked product) liner in a spherical bearing or rod end is a component that allows the unit to be "self-lubricating". Metal on metal bearings need to be lubricated. In certain applications this can be difficult to accomplish. Grease lubrication attracts dirt and may prematurely
  • No lube, no problem
    for lubrication, and handle high loads. Self-lubricating bearings make sense when relubrication is difficult or when operating conditions compromise liquid lubricants. Such bearings can also eliminate the need for special lubricants in food-processing equipment. Self-lubricated, nonmetallic Duralon bearings
