Ground & Precision Gears

JIS Grade 3–5 precision ground gears for aerospace, semiconductor, and high-accuracy servo applications.

KHK USA supplies JIS Grade 3–5 precision ground gears for applications where standard hobbed gears are not sufficient. These gears are manufactured to the tightest tolerances available in the KHK catalog, making them the preferred choice for aerospace, semiconductor equipment, medical devices, and high-accuracy servo drive systems.

Precision grinding removes the small tooth profile errors left by hobbing, resulting in significantly lower noise, smoother transmission of motion, and higher positional accuracy. For applications where backlash control and gear accuracy are critical, KHK ground gears deliver consistent, repeatable performance.

Ground & precision gear applications include:
– Aerospace actuation and control systems
– Semiconductor wafer handling equipment
– Medical imaging and surgical robotics
– High-speed servo and motion control
– Optical and measurement instruments
– Defense and ITAR-controlled systems

All precision ground gears are factory direct from KHK Japan, ISO 9001:2015 certified, and available with no minimum order quantity.
