How to Choose the Right Spur Gear (3 MOD)

Correct gear selection ensures improved efficiency, reduced wear, and optimal system reliability.

1. Determine Gear Module

The module defines the tooth size. MOD 3 is suitable for medium-load, mid-sized mechanical systems.

2. Identify Tooth Count & Gear Ratio Needs

Gear ratio is defined by tooth count. Ensure correct matching with mating gears.

3. Select Bore Type

Choose between:

• Stock bore
• Machined bore
• Keyway + set screw
  Depending on your shaft design.
  

4. Consider Operating Conditions

Check:

• Load and torque level
• Speed and duty cycle
• Shock/vibration environment

5. Confirm Gear Mounting Style

Available in plate type and B-hub type, depending on stability and mounting space.
