OuNaiDa set sail in Tianjin, on the shores of the Bohai Sea. From the birth of our first sprocket, we focused on the transmission industry.
Our product matrix expanded rapidly, and we fully mastered the core processes of gear manufacturing, completing our initial leap from single parts to transmission system components.
Focusing on mastering gear precision, we embedded "precision transmission" into our brand DNA.
Deepening the Strategic Footprint. A complete transmission ecosystem centered on gears, gear racks, sprockets, roller chains, and synchronous pulleys has been established, providing one-stop transmission solutions for global customers.
A world-class "milling and turning machining center" was introduced. Production efficiency and machining accuracy achieved exponential growth, ushering in a new era of digital manufacturing.
Technological sovereignty and quality justice. Significant investment was made in introducing coordinate measuring machines (CMM) and CNC rack grinding matrices, establishing an absolute competitive advantage in the rack sub-segment and defining the industry's precision ceiling.
A year of glory, empowered by technology. OuNaiDa successively obtained three international authoritative certifications: CE, ISO9001, and RoHS.
December 2025: The company officially changed its name to "Tianjin OuNaiDa Transmissions Technology Co., Ltd."
