Why Choose This Configuration?

This exact model is best suited to buyers who specifically need a CM040 gearbox with a 30:1 ratio and a 18mm hollow bore output. Medium ratios offer a versatile middle ground, reducing speed enough to improve torque while still maintaining practical shaft rpm for many industrial drives. Compared with larger sizes, this version is usually preferred where installation space matters, while still delivering the dependable performance expected from the Transtecno CM range.

Frequently Asked Questions

What does a 30:1 worm gearbox do?

A 30:1 worm gearbox reduces the input speed and increases available output torque through a compact right-angle transmission arrangement. In practice, this means a balanced reduction between output speed and torque multiplication.

What is this CM040 gearbox commonly used for?

This gearbox is commonly used in conveyors, packaging machinery, feeders, process equipment, material handling systems, and general industrial machinery where compact right-angle speed reduction is required.

What housing material does this gearbox use?

This model uses a Die-cast aluminium housing. In the Transtecno CM range, sizes 030 to 110 are aluminium, while size 130 is cast iron.

Does this gearbox require regular oil changes?

Under normal operating conditions, no. The CM wormgearbox range is supplied with permanent synthetic oil long-life lubrication, viscosity grade 320, so it is generally considered maintenance-free.

Can this gearbox be mounted in different positions?

Yes. The CM range can be installed in multiple mounting positions including M1 (B3), M2 (V6), M3 (B8), M4 (V5), M5 (B7), and M6 (B6).

What operating temperature range applies?

For this gearbox size, the standard operating temperature range is -25°C to +50°C, subject to correct installation and normal operating conditions.
