TOR MARINE SRL

What TOR MARINE SRL does

TOR MARINE SRL is an Italian private limited company (Società a Responsabilità Limitata) founded in 2011 in Paderno Dugnano, near Milan, from the merger of two established nautical-sector operators. The company designs and manufactures high-precision technical components for inboard marine propulsion systems, serving recreational boats (imbarcazioni da diporto), sailing vessels (imbarcazioni a vela), and work boats (imbarcazioni da lavoro). Its core technology is precision CNC machining applied to marine-grade materials — bronze, brass, AISI 316 and AISI 630 stainless steel, duplex F51 steel, C45 galvanized steel, NBR70 nitrile rubber, and polyurethane resin — with capabilities including h8-tolerance propeller shafts (25mm-150mm diameter, up to 6.5m length), self-centering flanges with 0.02-0.04mm concentricity error, and proprietary water-lubricated bearing technology that maintains operating temperatures below 50-60°C.

The product portfolio is a vertically integrated propulsion line covering propeller shafts, propeller blades (up to 2500mm diameter in OTS martensitic stainless steel or Nibrall bronze-aluminum alloy), brass and resin bearings, mechanical and grease seals, stuffing boxes, stern tubes in bronze, brass, or GRP, fixed and adjustable flanges, cathodic-protection anodes, slip rings, elastic couplings, and rope cutters. The company operates as both an OEM manufacturer and a private-label producer for third parties, and can supply custom certifications from RINA, Bureau Veritas, and CE classification societies upon request.

TOR MARINE distributes exclusively through direct channels: a quote-based e-commerce storefront on its own website and direct phone/email consultation. No public pricing is published; all sales are processed via personalized quote requests. The company employs approximately 5 people, has no disclosed funding, no parent company, and no public financial reporting. Geographic scope is stated as Europe, served from a single production facility in Paderno Dugnano, with no identified distributor or reseller network.
