Tenfjord steering gear parts sourcing for rotary vane systems

Thruster and propulsion brands

How we handle Tenfjord requests

Tenfjord's rotary vane steering gear (SR562 through SR743, covering working torque from roughly 16 to 625 kNm) has gone through several corporate names over the decades — Tenfjord, then Rolls-Royce Marine, and now serviced under Kongsberg Maritime — so a nameplate reading Tenfjord, Ulstein or Rolls-Royce on an SR-series unit is usually the same underlying product line. Distance rings, seal rings, gaskets and packing cord are typically identified by a drawing/position number stamped on the part itself rather than a standard catalog code, so a drawing reference or old parts-book page speeds up the check considerably.

Customers can send part numbers, maker references, equipment model data, serial numbers, nameplates, photos, drawings, old offers or previous supply documents. We review the information before quoting so the request is handled as a technical procurement task rather than a generic product search.

Brand names on this page are used only to identify equipment, models, parts and buyer search references.

How to send a useful Tenfjord RFQ

Attach the clearest technical information available. A single photo of a nameplate, an old offer line or a marked drawing can prevent delays when there are similar models, revisions or connection types.

If the item is obsolete or hard to identify, include dimensions, application notes and any alternative references already checked by your engineering team. We can review the request and reply by email with the next steps.
