Description
The driving gear is made of top quality Japanese POM material, integrated with high hardness of metal and abrasive resistance of plastics. Its shape and position hole benefit from simultaneous manufacturing with precision numerical control machines, thus high precision and excellent concentricity are guaranteed The metal rings are CNC precisely machined with 6061-T6 alloy. They are tightly embedded in the POM wheel, and fixed by several screws, making the parts form a perfect unit with high strength, capable of large load capacity. CNC gear hobbing machine contributes to the high precision of driving gear, and solves those problems found in stock plastic gear, such as slippage phenomenon and beating problem.
