The Plastic Spur Gear 60mm 38 Teeth has a 60mm outer diameter, 38 teeth, 12mm body width, and 6mm center hole diameter in yellow plastic, designed for robotics and DIY gear reduction builds. This spur gear is the first in StemVolt’s spur gear lineup to specify gear body width — at 12mm wide it has the greatest tooth face width of any gear in the range, and wider tooth face directly increases the load-bearing contact area between meshing teeth, giving this gear higher torque capacity per tooth than narrower gears of similar pitch.
The 60mm spur gear’s 38 teeth on a 60mm body gives a coarser tooth pitch than the 38mm/57T gear covered separately — fewer, larger teeth on a bigger body means each individual tooth is stronger and less prone to stripping under load than finer-pitched alternatives, making this plastic spur gear better suited for moderate-torque sustained operation. Paired with the 15-tooth pinion, this gear produces 38:15 = 2.53:1 reduction, and the 6mm center bore fits standard DC motor output shafts used across StemVolt’s motor lineup.
this 38 teeth spur gear’s 12mm body width requires 12mm of axial clearance in the chassis frame — more than the narrower gears in the lineup — so chassis designs need adequate shaft length and frame spacing to accommodate the wider gear body before installation. Available from StemVolt, offering quality robotics parts and DIY kits at competitive prices. This 60mm 38-tooth plastic spur gear is ideal for robotics projects, DIY builds, gear transmission systems, and educational mechanical applications.
