OUR MAST BEARINGS

General features

The mast bearings are large Type 4 bearings with Ertalyte rollers. They are intended for rotating masts.

  • These are self-aligning bearings installed on the deck and we can supply them with seals on request,
  • The low bearings are placed on the bottom of the hulls without the need for sealing. They can be replaced by a ball washer.

MAINTENANCE

  • The vessel doesn’t need to be dismasted for bearing maintenance,
  • These self-lubricated bearings need little maintenance.
