Full Overhaul & Bonding, Servicing Simplex  Stern Seals Worldwide

Does the propeller shaft need to be removed to replace SKF Simplex® seals?

In many cases, no shaft removal is needed. Our team can replace SKF Simplex stern tube seals or Simplex compact seals using bonding methods, both afloat or in dry dock, within just three to four days.

However, if your vessel requires chrome steel liner replacement, then removing the shaft becomes necessary to access the housing and complete the work properly. This is typically performed during scheduled dry dock.
