Application areas/scenarios

Implemented in EV transmission parking locks to hold the vehicle stationary when switched off. In a high-end EV prototype, this gear helped achieve reliable parking hold performance, reduced mechanical noise, and improved overall gearbox durability by extending the parking mechanism lifespan by 40%

Q1: What makes your precision gears unique?

A1: DDGear’s precision gears stand out for their ultra-tight tolerances (ISO ≤ Class 4), hardened alloy material (e.g., 20CrMnTi, 42CrMo), micron-level surface finishes (Ra ≤ 0.8 µm), and superior wear resistance. They are optimized for minimal vibration and long service life, making them ideal for applications such as robotics, EV drivetrains, AGVs, and medical devices.

Q2: Can you customize gears to our exact specifications?

A2: Absolutely. We offer both OEM and ODM services—including design refinement, material selection, and tailored manufacturing. Our engineering team supports you from prototype to mass production, with flexible options for module, bore type, and heat treatment.

Q3: How long is the lead time for prototypes and production?

A3: For gears with existing tooling, typical lead time is around 15 days. For custom parts, sample production takes 2–3 weeks depending on complexity. We prioritize fast turnaround while ensuring top precision.

Q4: What quality standards and certifications do you adhere to?

A4: We operate under ISO 9001 and IATF 16949 quality systems and comply with ISO 1328, DIN, and AGMA standards. All gears go through SPC monitoring, CMM checks, noise/vibration testing, and full traceability documentation to ensure consistent performance.

Q5: What industries do you serve, and what makes your service reliable?

A5: DDGear serves over 30 countries and has collaborated with leading OEMs across robotics, EVs, AGVs, medical equipment, industrial automation, e-bikes, and automatic doors. Our in-house manufacturing capabilities—covering everything from design to production—ensure short delivery cycles, high quality, and flexible volume scaling.
