Scroll down to discover more about our core product lines. If you have any other requirements, please contact us – we will custom build to match your specifications,
Standard Line
Torque Limiter
The STM UK Torque Limiter protects transmission from overloads, shocks or any other irregularities. Outshining traditional gearbox clutches our Torque Limiter is protected from potential pollutants like water, oil or dust.
This Torque Limiter is reliable and easy to adjust from the exterior of the gearbox - simply turn an adjustable nut. It can slip for several minutes at a time without incurring damage.

Worm Gearbox
The STM UK Worm Gearbox is reliable and durable. It features housings, fixtures and feet made from SG-AISi UNI 1706. Steel Wormshafts are casehardened, hardened and ground and the thread grinding in the gear ratios is carried out with ZI-Profile.
This enhances contact between the toothed surfaces, reduces noise and maximises performance. The STM UK Worm Gearbox also features a G20 cast iron hub upon which a GcuSn12 UN17013 bronze casting is fitted.

CRMI Double Worm
The STM UK CRMI Double Worm Gearbox features cast iron G20 UNI 5007 housings, flanges and feet. Any smaller gearbox (28, 40, 50, 63, 70) uses aluminium SG-AISi UNI 1706.
ZI-Profile in the thread grinding in the gear ratios permitted by the module value enhances contact between toothed surfaces. The CRMI Double Worm therefore boosts performance and reduces operating noise.

CB – Helical Worm
The STM UK CB – Helical Worm gearbox has been designed using modern design processes for durability and longevity.
The CB – Helical Worm range features engineering cast iron G20 UNI 5007 housings, flanges and feet. Any smaller gearbox models (40-50) use aluminium SG-AISi UNI 1706.
Torque limiters equipped with stop devices and assembly on to variators may be applied to the STM UK CB – Helical Worm range.

RMI - Wormbox
The RMI-Wormbox range features engineering cast iron G20 UNI 5007 housings, flanges and feet. Any smaller sized gearbox models (28-40-50-63-70) use aluminium SG-AISi UNI 1706 for housings, flanges and feet instead.
The wormwheel has a G20 cast iron hub with a casting fitted in GcsSn12 UNI7013 bronze. Taper roller bearing or radial ball bearings offer increased longevity in the RMI-Wormbox.

VM Variators
VM Variators are oil lubricated planetary gearboxes that allow continuously changing output speeds via manoeuvring a hand wheel.
Our VM Variators feature biconical shaped satellites that transfer the friction and torque between inside and outside track. With variable exterior radial position, the transmission ratio may be modified.
