Simplex Compact

The Blohm+Voss Simplex Compact is a compact lip‑seal assembly for stern tubes that provides oil‑tight sealing of the propeller shaft using an integrated spring and chromium‑lined sealing surface. As a Stern Tube Seal, it is normally installed in the propulsion train between the prime mover, gearbox and propeller or within the stern-tube and propulsor arrangement. In that role, its primary purpose is to transmit torque, support the shaft, seal the hull penetration or control propeller thrust according to the listed component. Shafts, bearings, seals, couplings, CPP mechanisms and shaft generators perform different roles, so alignment, lubrication and wear limits remain component-specific. Capacity: Per propulsion shaft design. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
