Why choose our helical gears?
Smoother Engagement
Gradual tooth contact reduces noise and vibration. Perfect for noise-sensitive applications.
Higher Load Capacity
Sloping tooth contact line distributes load across larger area. 30-50% higher than spur gears.
Greater Contact Ratio
Multiple teeth in contact simultaneously. Smoother torque transmission with less vibration.
Precision Ground
Optional tooth grinding for ISO 3-5 precision. Ideal for high-speed and high-precision applications.
