The STM Right Angle Helical Worm Gearbox CB from HMA Flow & Industrial has been designed on the basis of using a single body to accommodate all gear ratios. This solution allows for efficient heat dissipation, in addition to a rigid housing rand application simplicity.

Not only is the efficiency greatly improved, but also the longevity, while the highest transmittable torque possible is achieved for each size. The compromise of cost/performance is particularly centred in the middle range of reduction ratios.
