Custom CNC Bevel Gears | Spiral & Straight Bevel Gear Manufacturer – HKAA

Bevel gears are specialized gears used to transmit power between intersecting shafts, most commonly at a 90-degree angle. They are widely used in automotive differentials, machine tools, robotic arms, and industrial gearboxes due to their ability to maintain torque and speed under directional changes.

At HKAA Industrial, we provide custom CNC machining services for a wide range of bevel gear types, including straight bevel gears, spiral bevel gears, and hypoid gears. With our advanced multi-axis CNC equipment and gear cutting expertise, we deliver precision gears that meet the tightest tolerance and surface finish requirements.
