Worm Gear Set 20:1 Reduction Ratio, 0.5 Module - Brass Worm Rod & 20T Gear Wheel (3/4/5/6mm Bore) for Industrial Gearbox, Robotics, Conveyors (Bore-Rod 4mm x Gear 3mm)

Premium Brass Worm Gear Set - Engineered for precision motion control in compact industrial applications. Crafted from wear-resistant brass alloy, this 0.5 module gear set delivers smooth 20:1 speed reduction with 90° power transmission direction change.Unmatched Durability - High-density brass construction reduces friction by 40% vs. steel gears, extending service life to 50,000+ cycles. Resists corrosion, deformation, and pitting even under continuous high-torque loads.Precision Engineering - CNC-machined teeth ensure <0.1mm meshing tolerance for vibration-free operation. Ideal for noise-sensitive environments like medical devices or laboratory equipment.Technical Specifications:Material: Grade C36000 Brass (Lead-Free)Module: 0.5MTeeth: 20T Worm WheelReduction Ratio: 20:1Efficiency: 80-85%Exact Dimensions:Worm Wheel: 12mm H x 4mm OD x 11mm ID (0.47" x 0.16" x 0.43")Worm Shaft: 20mm L x 5mm OD x 10mm ID* (0.79" x 0.20" x 0.39")*Length measured from gear head to endUniversal Applications:Stepper Motor Speed Reduction (NEMA 11/17)3D Printer Z-axis Drives & Extruder GearboxesRobotic Joint Actuators & Conveyor Timing SystemsMedical Device Micro-Drives & Optical Instrument FocusersPackage Includes:1x Brass Worm Wheel (20 Teeth)1x Brass Worm Shaft2x Mounting ScrewsWhy Choose This Set? - Achieve 30% space savings versus multi-stage gear reducers while maintaining 15 N·cm torque capacity.
