Frequently Asked Questions

What does a 7.5:1 worm gearbox do?

A 7.5:1 worm gearbox reduces the input speed and increases available output torque through a compact right-angle transmission arrangement. In practice, this means higher output speed than mid or high-ratio worm gearboxes.

What is this CM130 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 Cast iron 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 -35°C to +50°C, subject to correct installation and normal operating conditions.
