Jiangsu Manqi Machinery Co., Ltd. is a specialized manufacturer of high-quality planetary gearboxes, based in Suzhou, China, with a factory area of 10,000-30,000 square meters and over 7 years of production experience. Our NBD560 Large Torque Planetary Speed Reducer is engineered for demanding industrial applications that require high load capacity, reliable power transmission, and compact design. This inline planetary reduction gearbox combines a robust housing with precision-ground planetary gears, delivering exceptional torque density and long service life. Whether you need to drive heavy conveyors, mixers, or rotary equipment, the NBD560 is the ideal choice for achieving efficient speed reduction and torque multiplication.
The NBD560 series is built to handle the toughest operating conditions. Its inline configuration allows for easy integration into existing drivetrains, while the planetary gear architecture ensures balanced load distribution and minimal vibration. Below are the key technical specifications and features that set this gearbox apart from conventional solutions.
Key Features & Benefits
- High Torque Capacity & Load Sharing: Multiple planet gears distribute the load evenly, enabling the NBD560 to transmit high torque without premature wear. This translates to reliable operation even under shock loads.
- Compact Inline Design: The coaxial input and output shafts save valuable space in machinery layouts, making it suitable for applications with tight mounting constraints.
- Efficiency >95%: Optimized gear tooth profiles and precision bearings minimize friction losses, resulting in lower energy consumption and reduced heat generation.
- Long-Lasting Durability: All gears are made from case-hardened alloy steel and ground to high precision (DIN 6-7 grade). The housing is made of high-strength cast iron or steel, ensuring resistance to deformation under heavy loads.
- Low Noise & Vibration: Helical planetary gears provide smoother meshing compared to spur gears, reducing noise levels to below 75 dB under normal operation.
- Flexible Mounting Options: Available with foot, flange, or hollow shaft outputs, and can be installed in any orientation (with proper lubrication).
- Wide Reduction Range: Standard reduction ratios from 3:1 up to 100:1 are available, with custom ratios possible upon request. The gearbox can be used with servo, stepper, or standard AC motors.

Application & Customer Benefits
The NBD560 is widely used in material handling equipment, packaging machines, crane drives, industrial mixers, and automation systems. Its high torque density allows designers to downsize motors while maintaining performance, reducing overall system cost. The low backlash option enhances precision in positioning applications, and the robust construction minimizes maintenance intervals. Customers from Eastern Europe, Southeast Asia, Africa, and South Asia have adopted our gearboxes for their reliability and competitive pricing.
As a dedicated manufacturer, we control every step from raw material procurement to final assembly. Our quality management system includes 100% run-in testing and dimensional inspection before shipment. The NBD560 can be customized with special output shafts, flanges, seals, or coatings for harsh environments such as dust, moisture, or high temperatures.
Trust & Reliability
Founded in 2017, Jiangsu Manqi Machinery Co., Ltd. has built a solid reputation in the gearbox industry. With a factory area of 10,000–30,000 square meters and a skilled team of 11–50 employees, we have the capacity to deliver consistent quality and on-time delivery. Our products are exported through the Port of Shanghai to multiple continents, serving diverse sectors from mining to food processing. We stand behind our gearboxes with a 12-month warranty and responsive technical support. Choose the NBD560 for a durable, high-performance inline planetary reduction solution.
Frequently Asked Questions (FAQ)
- 1. What is the expected service life of the NBD560 gearbox?
- Under normal operating conditions (rated load, proper lubrication, and ambient temperature below 40°C), the gearbox typically exceeds 20,000 hours of operation. Heavier loads or higher speeds may reduce life; we recommend periodic oil changes every 2,000 hours or as per the maintenance schedule.
- 2. Can this gearbox be directly connected to a servo motor?
- Yes, it is compatible with servo motors. For servo applications, we recommend selecting the low backlash option (≤5 arcmin) and using a suitable bell housing or input flange. Please provide motor shaft dimensions and mounting pattern for a custom adapter plate.
- 3. What lubrication is required and how often must it be changed?
- The NBD560 is typically filled with synthetic EP gear oil (ISO VG 220 or 320). First oil change after 200 hours of run-in, then every 2,000-3,000 hours or annually, whichever comes first. Sealed-for-life versions (grease lubrication) are available for limited-duty applications.
- 4. Is it possible to mount the gearbox with the output shaft facing upward?
- Yes, vertical mounting is possible, but you must specify the orientation when ordering so we can provide adequate splash lubrication or a forced lubrication system. Improper lubrication may cause premature wear.
- 5. What is the noise level during operation?
- Under rated speed and torque, the noise level is typically ≤72 dB(A) for single-stage reducers and ≤78 dB(A) for multi-stage versions. Precision gearing and sealed bearings contribute to quiet operation.
- 6. Can I get a custom ratio not listed in the standard options?
- Yes, we can produce custom ratios by modifying the gear sets. However, lead time and minimum order quantity may apply. Please contact our sales team with your specific requirements.
- 7. What are the available output shaft configurations?
- The NBD560 can be supplied with a solid keyed shaft, splined shaft, hollow shaft, or a flange output. We also offer dual output shafts or special lengths upon request. Detailed drawings are available for approval before production.
- 8. Do you provide testing certificates or performance reports?
- Yes, each gearbox is subject to a loaded run test, and we can provide a test report including temperature, noise, vibration, and torque data. Certificates of compliance are also available. Note that third-party inspection can be arranged at the customer's cost.
