Frequently Asked Questions (FAQ)

Q: What is the typical backlash value for the NGW123 reducer in robotic arm applications?
A: The standard NGW123 series is designed for low backlash. The exact value (often specified in arc-minutes) is application-dependent and can be customized. We provide detailed specifications based on your required ratio and torque load.
Q: Can this reducer be directly coupled to my specific brand of servo motor?
A: Yes. The NGW123 features a standard input shaft and flange design that is compatible with interfaces from major servo motor manufacturers. We can also provide adapters or customize the interface if required.
Q: What are the main differences between the aluminum alloy and cast iron housing options?
A: The aluminum alloy housing offers significant weight reduction, which is beneficial for high-speed or articulated robots where inertia is a concern. The cast iron housing provides superior rigidity, vibration damping, and heat dissipation, ideal for heavy-load or high-stress applications.
Q: Is the gear ratio fixed, or can I request a custom ratio?
A: Ratios are fully customizable. We work with you to determine the optimal reduction ratio based on your motor speed, required output speed, and torque.
Q: What is the expected service life, and what maintenance is required?
A: With proper installation and within specified load limits, the reducer is designed for a long operational life. It is pre-lubricated with long-life grease, typically requiring no maintenance during its service interval. Re-lubrication details are provided in the manual.
Q: Do you provide 3D models or technical drawings for integration into our robot design?
A: Yes, 2D drawings and 3D CAD models (e.g., STEP, IGES) are available upon request to facilitate easy integration into your design software.
Q: What is your production lead time for a custom order?
A: Lead times vary based on customization complexity and order quantity. We provide accurate timelines upon receipt of your detailed specifications and work diligently to meet project schedules.
Q: Can this reducer be used in applications other than robotic arms?
A: Absolutely. While optimized for robotics, its low backlash and precision make it suitable for various automation equipment, including rotary indexing tables, machine tool axes, packaging machinery, and medical devices.
