White Plastic Spur Gear

Featuring a uniform array of external spur teeth and a central through-bore, these white plastic gears serve as low-friction transmission elements in mechanical drive systems. The disc-shaped structure includes a perimeter of evenly spaced mounting holes on the face, facilitating secure attachment to motor shafts or pulley hubs while ensuring stable torque transfer with reduced operational noise compared to metal counterparts.

Manufacturing precision focuses on maintaining strict concentricity between the inner bore and the outer tooth profile to minimize radial runout during high-speed rotation. Critical quality controls include verifying tooth pitch accuracy, profile symmetry, and the positional tolerance of the face-mounted holes to prevent assembly misalignment. The smooth surface finish helps reduce wear against mating components, making them suitable for applications requiring self-lubricating properties.

Production leverages ISO 9001 certified processes utilizing precision molding or CNC machining capabilities to achieve consistent dimensional stability across batches. Inspection is supported by optical measuring instruments and projectors to validate gear parameters such as module and pressure angle against customer specifications. Lead times and costs are determined by material selection (e.g., POM, Nylon/PA66), volume requirements, and specific tolerance grades defined in the provided technical drawings.
