Why Choose us

SLW Motor Highlights

  • Mid-size gearbox with higher torque headroom

    The 13mm form factor increases torque capacity compared with smaller gearboxes, making it suitable for more demanding compact mechanisms.

  • Clear progression from low to high reduction

    Lower ratios support faster output motion, while higher ratios focus on torque margin and smoother low-speed behavior.

  • Stage count aligned with stability

    As ratios increase, additional stages help maintain transmission stability without changing the external footprint.

  • Output interface tailored to the load

    Custom shaft interfaces help control slip and alignment when transmitting higher torque levels in small assemblies.

FAQ

Frequently Asked Questions

Higher ratios are typically selected to increase torque capacity while reducing output speed.

Which ratios are best for moderate-speed applications?
Lower ratios such as 6 and 9 are typically used when output speed is prioritized over torque.
When should I select ratios above 100?
Higher ratios are commonly chosen when torque margin and stable low-speed output are more important than speed.
Why do higher ratios use more stages?
Additional stages allow higher reduction while maintaining gear strength and transmission stability.
Can I choose output direction?
Yes. Same or reverse output can be selected to match your mechanism layout.
What information is needed for a custom output shaft?
Your coupling method, assembly approach, and any slip or positioning constraints.
