High Speed Resistance 20CrMnTi RC Aircraft Model Gears In China
RC aircraft model gears are micro precision transmission components designed for RC models, drones, FPV racers, helicopters, fixed-wing and turbojet models, including spur, helical, planetary and bevel gears. Made of high-strength light alloy, stainless steel or engineering plastics (POM/Nylon), they feature small module, high precision, high speed resistance, low noise and lightweight. They are critical parts for motor reduction, torque amplification, power reversing and distribution, enabling efficient flight and precise control of RC models.
Product Features
Micro Small-Module: Module 0.2–1.5mm, compact for tight spaces.
Lightweight: Light alloy/plastic reduces weight, improving endurance and agility.
Ultra-High Speed: Withstands 10,000–80,000rpm, stable without skipping.
High Precision & Low Backlash: ISO 4–7 grade, 0.01–0.05mm backlash, responsive.
Low Noise & Smooth: Helical meshing reduces vibration and noise.
High Strength & Impact Resistance: Surface hardened, resists centrifugal and shock loads.
Corrosion & Fatigue Resistant: Withstands high altitude, humidity and temperature changes.
Modular & Universal: Compatible with mainstream brushless motors, servos and gearboxes.
Precision grinding/honing (ISO 4–6) → Ultrasonic cleaning, NDT.
Dimensional, speed, meshing test → Anodizing/blackening, laser marking, packaging.
Why Choose us?
7-axis CNC Grinding:We adopt high-precision 7-axis CNC grinding machines, holding tolerances as tight as ±5μm, ensuring gears run quietly, smoothly and with outstanding durability.
Strong technical expertise: Our core R&D team includes doctoral and master’s professionals specializing in spiral bevel gear technology, providing strong technical support for complex projects.
Rigorous testing & high precision:All gears undergo 100% inspection with Gleason metrology systems. We can achieve DIN 6 grade accuracy with strict control over tooth profile and direction errors, keeping our quality at the industry-leading level.
High transmission efficiency: Our gear designs support a single-stage reduction ratio of up to 300:1, with actual transmission efficiency reaching over 95%, greatly improving energy utilization.
Excellent durability & cost efficiency: Our gears deliver 40% lower lifecycle cost and a failure rate below 0.5%, ensuring stable long-term operation and reduced maintenance costs.
Fast response & short lead time: Supported by our digitalized production process, we are able to shorten the delivery cycle to only 20 working days, helping you accelerate project development and launch.
Professional custom design capability:We provide fully customized gear solutions for applications requiring high-reduction, high-speed, heavy-load, low-noise, and special small-tooth profiles, based on your actual working conditions.
