Primary & Secondary Rotary Drive (RD2)

Primary rotation with secondary linear movement 12mm and 24mm versions. The RD2 and RD224 ranges are low backlash, high precision drives providing continuous primary rotation and secondary linear axis movement.

The RD2 uses the same primary axis movement as the RD1 and has the full RD1 options of extended shafts and motorisations. In addition, the RD2 is fitted with a high resolution actuator to give 12mm or 24mm linear movement. This operates the azimuthal (R2) or tilt (R3) movements of this standard VACGEN SH series sample holders. The standard linear resolution is 0.02mm, but angular graduations can be supplied. The secondary axis can be motorised to give 5 microns resolution in half step mode. Adjustable microswitches are included with the RD2 motor kit.
