SDM krachtvermeerderaars
Torque range: 50 – 680 Nm
For applications where tool access to the bolt is limited, The SDM (Small Diameter Multiplier) Gearboxes can provide you a solution.
Based on RAD’s long experience with planetary gear reduction technology, the SDM Gearboxes were originally designed for confined space applications in the aerospace industry. However, these versatile tools are useable in many industries were difficult to reach bolts need to be tightened.
The SDM Gearboxes can be combined with industry standard nutrunners (pneumatic, battery, electric) and have a maximum torque output up to 680 Nm. Final torque and RPM will depend on the chosen SDM gearbox model, its ratio and the capacity of the chosen nutrunner. Torque accuracy and repeatability will be similar as the chosen nutrunner.
All SDM Gearboxes are delivered with:
- SDM gearbox
- Tombstone mounting plate
- Standard nutrunner fixation
- Calibration certificate
Note:
- Mostly, bespoke reaction arms are needed for SDM applications. Therefore, reaction arms are not included.
