Manufacturing Processes & Capabilities

• Micro-Module Helical Tooling & Profile Control: Accommodates M0.2 to M1.5 modules with micro-tolerance tooling; precisely compensates for polymer shrinkage to maintain tight tooth profiles, low pitch-circle runout, and pitch consistency across all planet gears.
• Tight Pin-Bore Concentricity Molding: Forms center pivot pin bores with strict perpendicularity and concentricity relative to the pitch circle, minimizing eccentricity and rotational drag during high-speed planetary rotation.

Features & Advantages

• Compact Coaxial Packaging & High Reduction Ratios: Delivers single- or multi-stage high-ratio reduction within a minimal axial and radial envelope, maximizing torque density while saving critical mechanism space.
• Progressive Helical Mesh & Whisper-Quiet Drive: Helical teeth provide a higher contact ratio with gradual flank engagement, eliminating tooth impact shock and high-frequency whine for quiet operation.
• Symmetrical Load Distribution & Self-Lubricating Durability: Symmetrical multi-planet layout evenly shares dynamic loads to increase impact resistance; self-lubricating POM and Nylon formulations ensure minimal friction and extended maintenance-free service life.
