STM RMI Worm Gearbox

Product Code: RM

Product Code Extra

The RMI Worm Gearbox from STM is constructed from high quality materials to the highest standards using modern design and manufacturing practices for optimal durability and longevity.

This Industrial Gearbox range features engineering cast iron G20 UNI 5007 housings on sizes 110, 130, 150, 180. Any smaller sized gearbox models (28-40-50-63-70-85) use aluminium SG-AISi UNI 1706 for housings, flanges and feet instead.

The RMI Worm Gearbox from STM features worm shafts constructed from casehardened, hardened and ground steel.

The thread grinding in the gear ratios is carried out by ZI-Profile. This enhances contact between toothed surfaces, boosting performance and minimising noise when the RMI-Worm Box is in use.
