Miniature size, giant performance

RAD has originally designed the SDM (Small Diameter Multiplier) gearboxes for the aerospace industry where tool access is limited and quality and precision standards are high. Because of the compact design, the SDM gearboxes provides a solution for applications where tool access to the bolt is restricted and where high torque is needed.

The low weight and size reduce operator fatigue and eliminate the use of large and tiresome manual torque wrenches. Thanks to RAD’s highly developed multiplier technology, the wrenches will continue to perform reliably for years to come.
