Since 1980, we have been shaping motion with lightweight, durable, and high-performance plastic gears.

We offer an extensive range of standard technopolymer gears available for immediate delivery, ideal for any mechanical transmission requirement demanding precision, speed, and reliability.

Stagnoli: over forty years of innovation in plastic gears.

With an annual availability of 10 million units, we offer the widest range of standard thermoplastic gears held in stock. Our solutions effectively replace metal components, backed by ISO 9001 and IATF 16949 certifications, ensuring immediate dimensional accuracy and certified quality for every order. For items not held in stock, we guarantee availability within just 2 weeks from the date of request.

Over 3,000 catalogue references: standard plastic components ready to replace metal

GUARANTEED STANDARD QUALITY: FROM RAW MATERIAL TO WAREHOUSE-READY STOCK.

Every item in our catalogue follows a fully traceable process that ensures consistently high standards. The over 3,000 references in advanced engineering polymers – including PA6, POM and polyketone (PK), – are manufactured to micrometric precision and validated through gear reports that certify full dimensional compliance of every unit held in stock.

OVER 40,000 ANNUAL INSPECTIONS TO ENSURE STANDARDS OF EXCELLENCE.

Our in-house laboratory performs rigorous inspections on every catalogue batch using state-of-the-art instrumentation. Full material traceability and dimensional testing ensure that every single stock reference meets maximum repeatability and the most stringent technical standards in the mechanical engineering industry.
