Welcome to Jiangsu Manqi Machinery Co., Ltd. — a professional manufacturer specializing in high-performance gearboxes and transmission components. Our CGEAR MBY630 Large Torque Grinding Mill Gearbox is engineered for the most demanding milling applications in cement, mining, and mineral processing industries. Made from premium alloy steel with carburized gear parts, this gearbox delivers exceptional torque capacity, superior wear resistance, and long service life. As a direct manufacturer with a 10,000–30,000 sqm factory in Suzhou, China, we combine advanced heat treatment technology with precision machining to ensure reliable performance under heavy loads.
Key Features & Technical Specifications
High Torque Capacity: Designed for large grinding mills, the MBY630 handles extreme torque requirements with ease, reducing downtime and maintenance costs.
Alloy Steel & Carburized Heat Treatment: Gears are made from high-quality alloy steel (e.g., 20CrMnTi, 18CrNiMo7-6) and case carburized to achieve a surface hardness of 58–62 HRC, providing excellent fatigue strength and anti-wear properties.
Precision Machining: All gear teeth are ground to ensure smooth operation, low noise, and high transmission efficiency (≥96%).
Robust Housing: The gearbox casing is made from high-strength cast iron or welded steel, designed to withstand heavy impacts and harsh working environments.
Flexible Configuration: Available in multiple gear ratios, input/output shaft arrangements, and lubrication options (oil bath or forced circulation).
Easy Maintenance: Modular design allows for quick access to internal components, simplifying inspection and replacement.
