Airtac MSD Multi-Position Fixed Cylinder MSD6X20S

The MSD6X20S is a 6 mm bore, 20 mm stroke single-acting push type multi-mount cylinder. Like all MD multi-mount cylinders, it fixes from 6 directions (front, back, left, right, top and bottom) and can be mounted side by side to save space, with magnetic-switch slots around the square body and high guide precision. The 6 mm single-acting bore delivers a theoretical push force of 5.7 N at 0.5 MPa, and the 20 mm stroke is the maximum offered for single-acting versions of this series. Cushioning is a bumper, and it runs on air filtered to 40 um at 0.2-1.0 MPa (28-145 psi), 50-500 mm/s, from -20 to 70 C.

This is a genuine AirTAC part in the standard MD family (not the no-rotating MK family). This SKU carries the S suffix, so it is supplied with a magnet for position sensing; the magnet is optional and is only included where the model code shows S. Dimensions and sizing for your fixture are confirmed from the datasheet on request.

For light clamping and pushing tasks, name the force first: this 6 mm single-acting bore gives 5.7 N theoretical push at 0.5 MPa; if that is marginal, step up to a larger bore (16 mm gives 70.4 N single-acting at 0.5 MPa). If you need the rod held against rotation, choose the MK family instead of this MD variant. Acting type: this is a single-acting push type; double-acting (MD), single pull (MTD), double rod (MDD) and adjustable-stroke (MDJ) versions exist if your cycle needs them. Single-acting strokes run up to 20 mm, so this 20 mm stroke is at the top of the single-acting table - keep the stroke short, as long strokes in a compact body are best avoided. The trailing S means a magnet is fitted; omit S if you do not need sensing. Port thread is PT by default; choose a G-thread suffix if your fittings require it.
