Jiangsu Manqi Machinery Co., Ltd. presents the NBD500 Planetary Gear Reducer – a high-precision, compact power transmission solution designed for demanding industrial machinery. Engineered with a 20:1 reduction ratio and a robust 1500 Nm torque capacity, this gearbox delivers exceptional reliability and efficiency for applications requiring consistent speed control and high load handling. As a manufacturer with over 8 years of experience and a 10,000–30,000 sqm factory, we ensure every unit undergoes strict quality checks to meet international standards.
The NBD500 utilizes advanced planetary gear technology to achieve high power density in a compact footprint. Its hardened and ground gears provide smooth operation and long service life, while the cast iron housing ensures excellent heat dissipation and structural integrity. Whether used in conveyors, mixers, hoists, or packaging machinery, this gear reducer offers optimal performance and low maintenance.
Key Features & Technical Specifications
- High Torque Density: 1500 Nm output torque in a compact design, saving space on your machinery.
- Precision Gearing: 20:1 reduction ratio with helical planetary gears for smooth, quiet operation and minimal backlash (≤ 8 arcmin).
- Durable Construction: Cast iron housing and forged alloy steel gears, heat-treated for wear resistance.
- Efficient Lubrication: Oil bath lubrication with standard ISO VG 220 oil, ensuring reliable cooling and reduced friction.
- Flexible Mounting: Available in foot-mounted and flange-mounted versions to suit various installation layouts.
- Wide Input Speed Range: Accepts input speeds from 500 rpm to 3000 rpm, compatible with most standard motors.
- Low Maintenance: Sealed bearings and integral oil seals reduce the need for frequent servicing.

Frequently Asked Questions (FAQ)
Q1: What is the maximum input power for the NBD500 20:1 reducer?
A: The recommended input power range is 0.5–15 kW, depending on input speed and load profile. For continuous duty at 1500 Nm output torque, we suggest a motor between 3–7.5 kW. Please consult our technical team for specific applications.
Q2: Can I use this gearbox with a servo motor?
A: Yes, the NBD500 can be paired with servo motors if backlash requirements are moderate (≤ 8 arcmin). For higher precision (low-backlash), please inquire about our special “P” series with reduced backlash (≤ 3 arcmin).
Q3: What maintenance is required?
A: Initial oil change after 500 operating hours, then every 3000 hours or annually. Use ISO VG 220 synthetic or mineral oil. Check seals and breather periodically.
Q4: What is the operating temperature range?
A: Standard version works from -10°C to +60°C ambient. For higher temperatures (up to 90°C), we offer high-temperature grease and Viton seals as options.
Q5: Can I get a foot-mounted version?
A: Yes, the NBD500 is available in both foot-mounted (foot flange) and flange-mounted configurations. Please specify your preference when ordering.
Q6: What is the delivery time?
A: For standard models, delivery is 15–25 working days after deposit. Custom orders may require 30–45 working days. We ship from Port of Shanghai.
Q7: Do you provide any certification?
A: Our products comply with general industrial machinery standards. Specific certifications (e.g., ATEX, CSA) are available upon request at additional cost. Please contact us for details.
Q8: How do I ensure the reducer is correctly sized for my application?
A: We provide a free sizing calculation based on your motor power, output speed, and load type. Just share your application details, and our engineers will recommend the optimal model.
