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.

Parts and equipment we can review

Tenfjord RFQ scope

Use this page when your purchasing or engineering team needs review by part number, model, serial number, drawing, photo or old commercial reference.

SR562 / SR622 / SR642 / SR662 series steering gear parts

SR562 / SR622 / SR642 / SR662 series steering gear parts are checked against the unit type, serial number and installation drawing, since similar-looking units can differ in gearing or seal configuration.

SR722 / SR723 / SR742 / SR743 series steering gear parts

For SR722 / SR723 / SR742 / SR743 series steering gear parts, the unit size/type code, power rating and drive arrangement (mechanical, hybrid or electric) matter more than the product name alone.

rotary vane seal and gasket kits

Rotary vane seal and gasket kits are matched by shaft size, material and dimensions rather than by name, so a marked drawing or old part helps.

valve block and filter unit parts

Valve block and filter unit parts requests are quickest to check with type code, connection size and coil voltage (if solenoid-operated).

legacy Ulstein-branded steering gear parts

Legacy Ulstein-branded steering gear parts are checked against the unit type, serial number and installation drawing, since similar-looking units can differ in gearing or seal configuration.

rudder stock connection hardware

We review rudder stock connection hardware against the maker's model code and serial number, plus a photo or drawing where the part isn't clearly marked.

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.
