Technology / product information

Outer gears must maintain tight tolerances to ensure efficient power transfer, low noise, and stable rotation in machinery and automotive systems. HANEDA (Thailand) manufactures precision outer gears from hardened steels like SCM440 and SKD11 with ±0.01 mm tooth profile accuracy, ideal for high-load and high-performance applications.

■ High-Precision Outer Gears for Reliable Power Transmission
Outer gears used in automotive and machinery assemblies must meet strict dimensional and profile standards. Misalignment or uneven tooth finish can lead to vibration, wear, and transmission loss. HANEDA (Thailand) specializes in gear machining for hardened steel—offering tight profile control and complete inspection with CMM and microscopes.
