Onvio

What Onvio does

Onvio LLC is a privately held U.S. manufacturer of precision mechanical motion control components, headquartered in Salem, New Hampshire with a wholly-owned production facility in Puebla, Mexico. The company designs and builds planetary gearboxes (nine series spanning inline and right-angle configurations), cycloidal reducers (the proprietary Dojen line, positioned as the only true zero-backlash cycloidal reducer in the industry), integrated wheel motors for mobile robots, made-to-order timing pulleys and clamp plates, and precision machined parts. Its technology centers on tight-tolerance mechanical engineering, with quantifiable specs including backlash as low as 3 arc-min, ratios up to 225:1, torques up to 28,000 lb-in, 94% gearbox efficiency, 20,000-hour service life, and IP ratings ranging from IP54 to IP68 for harsh-environment deployment.

The company serves OEMs, startups, and automation innovators across robotics and automated systems, packaging machinery, food and beverage processing, material handling, and medical/industrial equipment, with custom solutions and contract manufacturing available for specialized applications including submersible, high-temperature, washdown, and food-grade environments. Revenue is generated through direct OEM sales of standard catalog products (with online configuration and quote tools and in-stock NEMA reducers for quick delivery) and through quote-based custom engineering projects and contract manufacturing services, with MOQs starting at 5 pieces for modified standards. The business operates on a direct, engineering-driven sales model with no intermediaries, supported by ISO 9001:2015 certification, USMCA-compliant tariff-free North American supply, and standard 2-week lead times on modified products. The company traces its origins to the 1982 founding of Dojen in Massachusetts and has been independent under the Onvio name since 2005.
