STM RMI 40 FAQs

What is the STM RMI 40 size best suited to?

STM RMI 40 gearboxes are commonly used on conveyors, packaging machinery, automation systems and general industrial equipment where a compact right-angle drive is required.

How should I choose the right ratio in STM RMI 40?

Choose the ratio based on your required output speed and load. Lower ratios keep output speed higher, while higher ratios reduce speed further and increase torque multiplication. The ratio links above help you compare the closest options quickly.

Should I compare this size with neighbouring STM families?

Yes. Comparing nearby STM sizes is a good way to check whether you need more torque capacity, a different footprint or a better replacement fit. The nearby size links on this page make that comparison quicker.

Can these be used as replacements?

Yes. If you are replacing an existing unit, match the model size, ratio and mounting style as closely as possible. Send us the existing details and we will help identify the most suitable replacement.

Do you offer help with replacements and cross-references?

Yes. If you are replacing an existing unit, send us the model details, ratio and mounting style and we will help you identify the most suitable STM replacement.
