The development of self-lubricated guidance systems arises from the need to solve the existing problems involved in lubrication. These are due either to the difficulty of access or to the convenience of continuous and permanent lubrication, which oils fail to ensure.
Graphite insertions, acting as a solid lubricant, allow to keep an excellent level of lubrication for plates or bushes through all their lifetime, ready for use at any time.
Through use, the bronze structure wear causes graphite insertions wear. The graphite dust resulting from this slight wear will be the responsible for lubricating the whole of the contact area.
The graphite insertions used are relatively small, in comparison with other manufacturers, in order to minimize the impact on bronze bush consistency and maximize the dispersal of solid lubricant.
