The Plastic Spur Gear 55mm 50 Teeth is a blue plastic spur gear with 55mm outer diameter, 50 teeth, and 6mm compatible shaft bore, designed for DIY robot gear trains and DC motor projects. This spur gear is the larger-diameter option in StemVolt’s spur gear lineup — compared to the 27mm 24-tooth spur gear covered separately, this 55mm 50-tooth gear is typically used as the driven output gear in a reduction pair, receiving drive from a smaller pinion gear mounted on the motor shaft.
The Plastic Spur Gear 55mm’s role as a driven gear in a gear train determines the speed and torque relationship at the output shaft — a smaller driving gear paired with this 50-tooth gear produces a gear ratio proportional to the tooth count difference, reducing output speed while multiplying output torque. Robotics project applications uses spur gear geometry where teeth run parallel to the gear axis and mesh along parallel shafts, making this plastic gear for dc motor builds straightforward to align and install compared to helical or worm gear alternatives.
With all plastic spur gears, the gear must match between this 55mm gear and any mating gear for correct tooth engagement — mismatched modules cause poor mesh, accelerated tooth wear, and transmission noise even when bore sizes are compatible. Available from StemVolt, offering quality robotics parts and DIY kits at competitive prices.
