Jiangsu Manqi Machinery Co., Ltd. is proud to introduce our Wear Resistant Heavy Load DBY355 Bevel Cylindrical Gearbox Mining Transmission Unit. As a dedicated manufacturer with a modern factory spanning 10,000–30,000 square meters, we specialize in producing robust transmission solutions for the mining industry since 2017. Our DBY355 gearbox combines advanced bevel and cylindrical gear technology to deliver superior torque transmission under extreme conditions, ensuring reliable operation in heavy-duty mining applications. With customized options and rigorous quality control, this gearbox is designed to maximize uptime and reduce maintenance costs for our global customers.
Key Features & Benefits
- Wear Resistant Design: The gears undergo special surface hardening and anti-wear coating to withstand abrasive mining environments, prolonging service life by up to 30% compared to standard gearboxes.
- Heavy Load Capacity: Engineered with high-strength alloy steel gears and oversized bearings, the DBY355 handles peak torque loads typical of conveyors, crushers, and mill drives in mining operations.
- Precision Gearing: Bevel and cylindrical gear stages are machined to ISO 6–7 accuracy, ensuring smooth meshing, low noise (≤75 dB at rated load), and high efficiency (≥95%).
- Compact & Robust Construction: The one-piece cast iron housing provides superior rigidity and vibration damping, while the compact footprint saves valuable installation space underground or on surface.
- Flexible Mounting Options: Available in horizontal or vertical configurations, with multiple input/output shaft orientations to suit existing equipment layouts.
- Customizable Parameters: We offer tailored ratios (from 5:1 to 200:1), input power up to 500 kW, and optional forced lubrication or cooling systems for extreme duty cycles.

Frequently Asked Questions (FAQ)
Q1: What does the model DBY355 signify?
A: DBY355 indicates the gearbox series (DBY – Bevel Cylindrical) and the center distance of the gearbox is 355 mm. This dimension helps determine the size and torque capacity.
Q2: Can this gearbox be used for applications other than mining?
A: Yes, while the design emphasizes mining transmission, its heavy-duty construction makes it suitable for cement mills, steel plants, and heavy material handling conveyors. Please contact us to confirm suitability for your specific application.
Q3: What is the typical lead time for a DBY355 gearbox?
A: For standard configurations (e.g., common ratios, horizontal mounting), lead time is approximately 30–45 working days. Custom orders may require 45–60 working days depending on complexity.
Q4: Do you provide technical drawings or 3D models?
A: Yes, we can provide dimensional drawings and 3D CAD models (STEP/IGES) upon request after an order is confirmed. This facilitates easy integration into your system design.
Q5: What are the available mounting positions?
A: The DBY355 supports horizontal (foot-mounted) and vertical (flange-mounted) configurations. Additional custom mounting brackets can be engineered for special requirements.
Q6: How is the gearbox lubricated and what type of oil is recommended?
A: The standard gearbox uses splash lubrication with mineral gear oil (ISO VG 320–460). For high-speed or extreme temperature conditions, forced lubrication with synthetic oil is optional. We provide detailed lubrication guidelines with the product manual.
Q7: What is the warranty period for the DBY355 gearbox?
A: We offer a standard 12-month warranty from the date of shipment, covering manufacturing defects in materials and workmanship. Extended warranty options are available upon negotiation.
Q8: Does the gearbox come with any certifications?
A: While we do not hold specific third-party certifications for this product line, our manufacturing process follows ISO 9001 quality system principles (not certified). All gearboxes are tested per our internal quality standards, and test reports can be provided. If your project requires specific certifications, please discuss with our sales team for possible compliance arrangements.
