Detailed Advantages for Your Business
Our split gear ring offers distinct benefits over one-piece gears:
- Ease of Installation: The split design eliminates the need to remove adjacent components, reducing downtime and labor costs.
- Cost-Effective Replacement: Instead of replacing an entire shaft assembly, you can replace just the gear ring, saving money.
- High Load Capacity: 40Cr steel with HRC 58-62 hardness provides excellent resistance to wear and plastic deformation under heavy cyclic loads.
- Consistent Accuracy: ISO 7 precision ensures smooth meshing, low noise, and minimal vibration, extending the life of mating gears.
- Customizable Options: We can adjust tooth count, module, bore size, keyway, and surface treatment to meet your specific requirements.
- Reliable Supply Chain: As a factory with 10,000-30,000 sqm production space and 51-100 experienced workers, we maintain stable production and timely delivery.
This gear ring is suitable for a wide range of machinery including gearboxes, reducers, crushers, conveyors, and wind turbines. Its robust construction ensures long-term performance even in harsh environments like mining sites or steel plants.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between a split gear ring and a solid gear?
A: A split gear ring is designed to be assembled around a shaft without removing the shaft or other components. It is ideal for repairs or upgrades where disassembly is difficult. -
Q: Can you customize the bore size or keyway?
A: Yes, we can machine the bore, keyway, and mounting holes according to your drawing or specifications. Please provide the details when ordering. -
Q: How do you ensure the hardness of HRC 58-62?
A: We perform hardness testing on every batch using Rockwell hardness testers. The heat treatment process is carefully controlled to achieve the specified range. -
Q: What is the lead time for this product?
A: For standard specs, lead time is typically 15-25 days after order confirmation. Custom orders may require additional time depending on complexity. -
Q: Is ISO 7 precision suitable for high-speed applications?
A: Yes, ISO 7 is a medium precision grade suitable for moderate to high-speed applications where smooth operation and low noise are required. For ultra-high precision, we can offer ISO 6 or higher upon request. -
Q: Do you offer samples for testing?
A: Yes, we can provide samples. However, sample cost and shipping charges apply. Please contact our sales team for details. -
Q: What is the minimum order quantity (MOQ)?
A: MOQ is typically 1 piece for standard sizes, but we encourage bulk orders for better pricing. -
Q: How do you package the gear ring for export?
A: We use sturdy wooden crates or pallets, with internal cushioning to prevent damage during transit. Each gear is individually wrapped and protected.
