We ship through major ports including Shanghai, Lianyungang, Qingdao, and Tianjin.
Key Features & Technical Specifications
High-Grade Material: 35CrMnSi alloy steel offers excellent strength, toughness, and wear resistance, ideal for heavy-load kiln drives.
Precise Heat Treatment: Quenching and tempering process ensures uniform hardness of HB 320–360, balancing hardness and impact resistance.
Accurate Dimensions: Diameter 2000 mm with tight tolerances (typically ±0.5 mm or better) to ensure smooth meshing with pinions.
Durable Construction: Designed for continuous operation under high temperatures and abrasive conditions, with a service life exceeding typical industry standards.
Flexible Surface Finish: Available in rough turned, semi-finished, or fully finished conditions, with optional tooth profile grinding upon request.
Comprehensive Warranty: 24-month warranty covers manufacturing defects, with responsive after-sales technical support.
Customizable Options: We can manufacture gear rings with different diameters (up to 6000 mm), materials, hardness levels, and tooth profiles according to customer drawings.

Our gear rings are designed for easy installation and long-term reliability. The 2000 mm diameter is suitable for medium to large rotary kilns, and the 35CrMnSi material provides excellent resistance to fatigue and cracking. The quenched and tempered microstructure ensures a fine-grained structure that withstands high contact stresses, reducing maintenance frequency and downtime.
Trusted by global clients: Our products have been exported to over 30 countries, including the USA, Germany, Brazil, South Africa, and Australia. We maintain an annual export value of US$2.5–5 million, reflecting strong market confidence. Certifications such as HACCP, TL900, QS9000, SA8000, ISO9000 series, ISO14000, OHSAS18001, and others underscore our commitment to quality, safety, and environmental responsibility.
We offer flexible packaging options (wooden crates, steel frames, or custom packing) to ensure safe transportation. Typical lead time is 30–45 days, depending on order quantity. For urgent requirements, expedited delivery can be arranged upon request.
