Selection & Purchasing Guidelines

Do I need a planetary gearbox or a helical/worm gearbox for my application?

  • Planetary gearboxes are ideal for high precision, high torque density, and compact spaces (robotics, AGV, automation).

  • Helical gearboxes offer smooth operation and higher efficiency for continuous-duty industrial systems.

  • Worm gearboxes provide high reduction ratios and self-locking features for lifting and positioning.
    NUODUN offers all three types and can help you choose based on load, accuracy needs, duty cycle, and budget.

How do I determine the proper torque and safety factor when selecting a reducer?

Calculate the required output torque based on load, inertia, starting conditions, and working environment. Then apply a safety factor (typically 1.5–2.5) depending on load stability and shock levels. NUODUN provides torque calculation support and can customize reducers for heavy-shock or high-precision applications.

What factors affect the performance and lifetime of a gearbox?

Key factors include material strength, gear accuracy grade, lubrication quality, heat dissipation, load conditions, and alignment between motor and reducer. NUODUN uses hardened gears, precision machining, optimized lubrication systems, and strict testing to ensure long-term reliability.

How do I select the right gearbox among so many models?

Start by clarifying four core parameters: required torque, speed ratio, input motor type, and mounting structure. You should also consider duty cycle, backlash level, and expected lifetime. NUODUN’s engineering team can evaluate your application and recommend the optimal gearbox to ensure efficiency and durability.

How do I choose the right Screw Jack model for my application?

To recommend the perfect solution, we need a few key details:

  • Load Capacity: The total weight to be lifted (dynamic and static).

  • Speed: How fast the load needs to move (mm/s).

  • Stroke Length: The distance the load needs to travel.

  • Duty Cycle: How frequently the jack will operate per hour/day.

  • Orientation: Vertical (up/down) or Horizontal. Answer: Provide these parameters to our engineering team, and we will calculate the torque and power requirements to select the optimal model.
