Henan San Kuang Machinery Technology Co., Ltd. proudly presents our Split Ring Gear 2500mm Diameter 18 Module 40Cr Quenched and Tempered HB280-320. As a trusted manufacturer since 2014, we specialize in large-scale precision gears for heavy industries. This split ring gear is engineered to deliver exceptional durability and load-bearing capacity, making it an ideal solution for demanding applications such as mining mills, cement rotary kilns, and heavy-duty conveyor systems. Our commitment to quality and customer satisfaction ensures that every gear meets the highest standards of performance and reliability.
The 2500mm diameter split ring gear is crafted from premium 40Cr alloy steel, which undergoes a precise quenched and tempered heat treatment to achieve a hardness range of HB280-320. This process significantly enhances the gear's wear resistance, impact toughness, and fatigue life, ensuring long-term stable operation under heavy loads. With an 18 module design, the gear teeth are optimized for smooth power transmission and reduced noise, even in harsh environments. The split construction allows for easier installation, maintenance, and replacement without dismantling the entire shaft, saving time and labor costs.

Our split ring gear is designed to withstand extreme operational conditions. The 40Cr material, after quenching and tempering, exhibits superior tensile strength and yield strength compared to standard carbon steel gears. This makes it particularly suitable for applications where high torque and cyclic loading are present, such as in ball mills, rotary dryers, and kilns. The split design not only simplifies installation but also reduces downtime during maintenance, as one half of the gear can be replaced without removing the entire ring. Additionally, the gear can be machined with custom keyways, bolt holes, or alignment features to match your existing equipment.

Frequently Asked Questions (FAQ)
Q: What is the typical lead time for a 2500mm split ring gear?
A: Lead time depends on order quantity and customization. For standard designs, it is typically 30–45 days after confirmation. We can expedite for urgent orders upon request.Q: Can you provide the gear with a different hardness or heat treatment?
A: Yes, we can customize the heat treatment process (e.g., induction hardening, nitriding) to achieve specific hardness profiles. Contact our engineers for recommendations.Q: How do you ensure the gear's concentricity and tooth profile accuracy?
A: We use advanced CNC gear hobbing machines and conduct 100% inspection using gear measuring centers. All dimensions are verified against your drawing or our standard tolerances.Q: Is the split ring gear supplied with mounting bolts and alignment pins?
A: Standard supply includes the gear halves only. However, we can provide matching bolts, dowel pins, and installation instructions as optional accessories.Q: What is the maximum weight of this gear, and how is it packaged for export?
A: The weight depends on the tooth count and bore size, typically around 3,000–5,000 kg. We use heavy-duty wooden crates with steel bracing, and protect the gear surface with anti-rust oil and plastic wrapping.Q: Can you machine the gear with a keyway or other features?
A: Absolutely. We can machine keyways, tapped holes, spigot fits, or any other features per your drawing. Please provide detailed specifications.Q: Does this gear meet ISO or AGMA standards?
A: Our manufacturing follows ISO 1328 and AGMA 2000 standards. We can certify the gear to your required grade (e.g., ISO 8, AGMA 9).Q: What is the minimum order quantity (MOQ)?
A: For split ring gears of this size, the MOQ is 1 piece. We welcome both small replacement orders and large volume projects.
