Jiangsu Manqi Machinery Co., Ltd., a professional manufacturer based in Suzhou, Jiangsu, China, proudly presents the DCY Series Bevel Cylindrical Gear Reducer (models DCY400 to DCY630). With our factory spanning 10,000–30,000 square meters and a dedicated team of 11–50 experienced employees, we have been delivering reliable heavy-duty industrial gearboxes since 2017. This gearbox series combines a spiral bevel gear stage with a cylindrical gear stage, offering exceptional torque density, smooth operation, and long service life for the most demanding applications. Whether you need a robust solution for cement mills, mining conveyors, or steel processing equipment, the DCY series is engineered to meet your requirements.
Key Features and Technical Benefits
High Load Capacity: The bevel-cylindrical gear design allows for efficient power transmission with high torque output, ideal for heavy-duty industrial environments.
Hardened and Ground Gears: All gears are made from high-strength alloy steel, carburized, hardened, and precision ground to ensure durability, low noise, and minimal wear.
Modular Construction: Multiple housing configurations and mounting options (horizontal, vertical, foot-mounted, flange-mounted) provide flexibility for various installation layouts.
Efficient Lubrication System: Splash lubrication or forced oil circulation (optional) ensures stable operation and heat dissipation even under continuous heavy loads.
Compact and Rigid Housing: The cast iron or welded steel housing is designed to withstand high radial and axial loads, reducing vibration and extending equipment life.
Easy Maintenance: Accessible inspection covers, oil drain plugs, and breather valves simplify routine checks and oil changes, minimizing downtime.

Frequently Asked Questions (FAQ)
Q: What is the typical lead time for DCY series gearboxes?
A: Lead time depends on the model and quantity. For standard sizes, it is usually 30–45 days after order confirmation. Custom orders may require additional time.Q: Can the gearbox be used in vertical shaft applications?
A: Yes, the DCY series supports both horizontal and vertical mounting. For vertical installations, an optional oil pump and special sealing arrangements are recommended.Q: What type of lubricant should be used?
A: We recommend using mineral-based gear oils (ISO VG 220–460) depending on ambient temperature and load conditions. Full synthetic oil is optional for extreme temperatures.Q: Is the gearbox reversible?
A: Yes, the DCY series can operate in both directions. However, for applications with frequent reversing, please consult our technical team for additional precautions.Q: What is the maximum ambient temperature for operation?
A: The standard design allows operation from -10°C to +40°C. For higher temperatures, special seals and synthetic lubricants can be supplied.Q: Do you provide spare parts?
A: Yes, we offer comprehensive spare parts including seals, bearings, and gears. It is recommended to keep a set of critical spare parts for quick replacement.Q: Can the gearbox be customized for special output shaft configurations?
A: Yes, we can customize the output shaft size, keyway, and flange dimensions according to your equipment interface. Please provide your drawings for evaluation.Q: How do you ensure quality control?
A: We follow a strict quality management system: incoming material inspection, gear accuracy testing (DIN/AGMA standards), assembly run-in, and final load test with noise/vibration measurement. Each unit is issued a test report.
