Spiral bevel gears are a type of gear that features a spiral cut tooth shape, which allows for smoother and quieter operation compared to traditional straight-cut gears. They are commonly used in applications where high speed and low noise are required, such as in:

- Automotive differentials
- Aerospace applications
- Industrial power transmission systems
- Robotics

Spiral bevel gears have several advantages, including:

- Increased tooth contact ratio, which reduces noise and vibration
- Improved efficiency and reduced friction
- Ability to handle high speeds and loads
- Compact design, making them ideal for applications where space is limited.
