Our gear rings undergo rigorous inspection using CMM (Coordinate Measuring Machine) and hardness testers to ensure every unit meets the specified tolerances. The carburizing process is carefully controlled to achieve a uniform case depth, while the subsequent grinding operation guarantees the final geometry. This makes our gear rings ideal for automotive transmissions, agricultural machinery, mining equipment, and industrial gearboxes.

Frequently Asked Questions (FAQ)
-
Q: What is the typical lead time for this gear ring?
A: For standard sizes, lead time is 25-30 days after order confirmation. Custom designs may require 35-45 days depending on complexity. -
Q: Can you provide material certificates?
A: Yes, we supply a material test report (MTR) and hardness test certificate with each shipment. Third-party inspection is also available upon request. -
Q: What is the maximum outer diameter you can produce?
A: Our current capacity supports gear rings up to 2000 mm outer diameter. For larger sizes, please consult our engineering team. -
Q: Do you offer surface treatments other than carburizing, such as nitriding?
A: Yes, we can apply nitriding, induction hardening, or other surface treatments based on your requirements. Please specify in your inquiry. -
Q: How do you ensure the ±0.02mm tolerance is maintained?
A: We use precision grinding machines and in-process gauging. Final inspection is performed using a CMM with a resolution of 0.001mm. -
Q: Is the gear ring suitable for high-speed applications?
A> Yes, with proper balancing and tooth profile correction, it can be used in high-speed rotating equipment. We recommend dynamic balancing for applications above 3000 RPM. -
Q: What packaging do you use for export?
A: Each gear ring is individually wrapped with anti-rust paper and bubble film, then packed in wooden crates or steel pallets suitable for sea freight. -
Q: Do you offer samples before mass production?
A: Yes, sample orders are accepted. Sample cost is negotiable and can be deducted from the first production order.
