Spur Gear (4mm) 10 Teeth

The Spur Gear (4mm) 10 Teeth is a small spur gear with 10 straight-cut teeth, listed in the 4 mm size. Spur gears transfer motion between parallel shafts, and a small 10-tooth gear is often used as the driving pinion that turns a larger gear, reducing speed and raising torque in robots, models and DIY mechanisms.

Spur Gear (4mm) 10 Teeth Applications

• Motor pinions for speed-reduction gear trains
• Robot drives, arms and moving mechanisms
• Repairing gears in toys, models and small devices
• STEM lessons on gear ratios and mechanics

What's in the Box

• 1 × 10-tooth spur gear

Tip: Make sure both gears have the same module (tooth size), otherwise they will not mesh smoothly. To find the ratio, divide the driven gear's teeth by the driving gear's teeth: this 10-tooth gear driving a 30-tooth gear gives a 3:1 reduction, so the output turns three times slower with close to three times the torque.
