Durable High Precision Gears 13.5mm Derailleur Nylon Duplex Gear With 0.5m Modulus
Plastic duplex gears have a double gears design with different reference circles but same modulus , speed for big reference circle gear is slower than speed for small reference circle gear when they are driven under same power , this design is used to driven system with multiple purposes .
Material
Duplex gears are made from plastic nylon ( PA 66 )
