YYC gears are manufactured in accordance with DIN 867 standards, with tolerances and accuracy levels based on DIN 3962, 3963, and 3967 to delivering the highest quality rack and pinion systems for industrial applications.
YYC has not only traditionally induction hardness on racks but also highly advanced laser heat treatment in house, it promises precisely and efficiently innovative technology, the energy-efficient process also reduces carbon emission.
As one of the global leading brand of precision rack and pinion brand, YYC manufacturing managements are ISO 9001 and ISO 14001 certified, ensuring that our production processes meet international standards. Each step in the manufacturing process is inspected by our skilled machine operators, and detailed measurement reports are available upon request to confirm the quality of our products.
To optimize quality and capacity, YYC has automated factory including robotic system on milling, drilling, grinding, hardening, inspecting and packing working stations makes YYC rack and pinions are on state-of-the-art precision high level.
Combining standardized efficiency with customized flexibility — YYC’s dual-track manufacturing power.
YYC strives to provide customers with the highest-quality rack and pinion solutions, ensuring precision and reliability in every application.
To make your design process more efficient, YYC offers two powerful digital tools that simplify product selection and configuration.
Our Filter Tool allows you to instantly find the right rack and pinion based on key parameters such as module, tooth profile, material, precision grade, heat treatment, and length.
With just a few clicks, engineers can quickly narrow down thousands of SKUs to locate the exact model that meets their mechanical and performance requirements — saving valuable time during the design phase.
In addition, YYC proudly cooperates with Servosoft, an advanced engineering software that helps you simulate and validate motion profiles, loads, and system dynamics.
Servosoft ensures accurate sizing and optimal configuration of your rack and pinion system, allowing you to design with confidence and eliminate uncertainty before production.
Whether you are developing complex industrial machinery or high-precision automation systems, the combined use of YYC’s Filter Tool and Servosoft empowers you to achieve faster, smarter, and more reliable engineering decisions.
