Product Features and Technical Specifications
- High-Quality Material: Made from ZG42CrMo alloy steel, which provides excellent strength, toughness, and resistance to thermal fatigue. This material is ideal for high-temperature kiln environments.
- Precision Machining: Manufactured to 8-level accuracy (ISO 1328 Class 8), ensuring smooth meshing with pinion gears, reduced vibration, and lower noise during operation.
- Optimal Module Design: Module 28 is specifically selected for heavy-duty cement kiln drives, balancing torque transmission and gear tooth strength.
- Heat Treatment: The gear undergoes quenching and tempering to achieve a uniform hardness of HRC 45–50 (surface), enhancing wear resistance and extending service life. Custom heat treatment options are available upon request.
- Customizable Dimensions: Teeth number, outer diameter, bore size, and weight can be tailored to match your specific kiln drive system. Our engineering team works closely with clients to ensure perfect fit and performance.
- Rigorous Quality Control: Each gear is tested for dimensional accuracy, material composition, hardness, and magnetic particle inspection (optional) to ensure defect-free products.

Frequently Asked Questions (FAQ)
1. What is the typical delivery time for a Mod 28 girth gear?
Delivery time depends on the specific dimensions and quantity. For standard designs, it is usually 60–90 days after order confirmation. For custom orders, please contact our sales team for an accurate lead time.
2. Can you provide a girth gear with a different material, such as 42CrMo4 or 35CrMo?
Yes, we offer various material options based on customer requirements. ZG42CrMo is our standard for high-temperature kiln applications, but we can also produce gears in 42CrMo4, 35CrMo, or other alloy steels upon request.
3. What is the maximum outer diameter you can manufacture?
Our factory can handle girth gears with outer diameters up to 12 meters. For larger sizes, please consult with our engineering team for feasibility.
4. How do you ensure the 8-level accuracy is maintained during production?
We use CNC gear hobbing and shaping machines, followed by precision grinding. Each gear is inspected using coordinate measuring machines (CMM) and gear testers to verify tooth profile, lead, and pitch accuracy.
5. Do you offer heat treatment services for the entire gear?
Yes, we provide full heat treatment including quenching, tempering, and surface hardening (induction or flame). The specific heat treatment process is customized based on the material and required hardness.
6. What is the expected lifespan of this girth gear under normal cement kiln operating conditions?
Under proper lubrication and maintenance, the gear can last 8–15 years depending on load cycles and operating environment. Our material selection and heat treatment significantly extend service life.
7. Do you provide installation guidance or on-site support?
Yes, we offer technical documentation and remote support. For large projects, our engineers can be dispatched to site for installation supervision (additional cost).
8. What are the payment terms and shipping options?
We accept T/T, L/C, and other common terms. Shipping is arranged via sea freight from ports of Shanghai, Qingdao, Tianjin, or Lianyungang. We can handle FOB, CIF, or CFR terms as per your preference.
