STRUCTURE OF THE SEALED & LUBRICATED TRACK TRACK STRUCTURE Sealed & lubricated track differs greatly from grease sealed track in the following point. Oil is sealed in the area between pin and bushing (link connection), and special seal is used to prevent entry of soil or water. This greatly improves the elongation life of link pitch. Sealed & lubricated track consists of the links, pins, bushings, seals, spacers, large plugs and small plugs. As for the track that we adopted this time, the following points are changed formerly. 1. The adoption of F5 type seal that improved sealing follow-up ability. 2. The adoption of wedge ring that maintain the pin hold.
