About the Airtac MGD Double Rod Mini Cylinder MGD20X100
The MGD20X100 is a double acting, double-rod JIS round-body mini cylinder with a 20 mm bore and 100 mm stroke. A piston rod exits both the front and back covers with the same M8x1.25 male thread at each end, so the two rod ends move together and the output force is equal in both directions: about 131.9 N each way at 0.5 MPa and 184.7 N at 0.7 MPa, with a theoretical maximum of 26.9 kgf at 1.0 MPa. Because both sides of the piston see the rod-side area, there is no separate push and pull figure, and the through-rod naturally resists rotation and side load.
Construction follows the JIS mini-cylinder footprint: a SUS304 stainless barrel with hard-chrome plated carbon-steel rods, riveted covers and a two-way lubricant-storing piston seal, so it suits damp and washdown-adjacent lines. A fixed anti-impact bumper pad softens each stroke end, though it is not an adjustable cushion and will not hold a load on air loss. Ports are 1/8" on this bore, operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof, speed range 30-800 mm/s, and temperature -20 to +70 C. Halving the 0.5 MPa force gives a safe vertical load of roughly 7 kg. Add the S code if you later want CMSG, DMSG or EMSG switch sensing.

Where the Airtac MGD Double Rod Mini Cylinder MGD20X100 Is Used
Anti-rotation slide
The through-rod keeps a small 100 mm-stroke slide square without external guides, delivering 131.9 N equally on extend and retract for symmetric indexing at low side load.
Twin-load push
Drive two light fixtures or clamps from the same cylinder: the front and rear M8x1.25 rod ends each see the full rod-side force, so both loads move in step at 30-800 mm/s.
Rear-mounted flag station
Use the back rod end to carry a stop or switch flag while the front rod does the work; add the S code magnet to run CMSG or DMSG switches for end-of-stroke confirmation.
Is the Airtac MGD Double Rod Mini Cylinder MGD20X100 the Right Cylinder?
At 131.9 N per direction at 0.5 MPa, the MGD20X100 is the smallest MGD force class; size up to the MGD25 (about 206 N) or MGD32 (about 346 N) if your load needs more, or to the MGD40 for the largest output. Choose the MGD over the single-rod MG when you need anti-rotation, equal force both ways, a rear rod end for a stop flag or a second driven load; choose MG for a conventional single-rod package. If you need an adjustable air cushion or a 50/63 mm bore, the double-rod MGCD is the right family. Mount with LB foot or FA flange and add I or Y rod knuckles at the ends (no SDB/CB pivot on the double-rod). The 100 mm stroke is well inside the 300 mm maximum standard stroke for this bore; for long strokes keep side load on the rod low and guide the load externally. This unit has no magnet, so no position sensor can be fitted; order the S code for CMSG/DMSG/EMSG switching.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check On first run, back off the cushion/impact settings and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MGD Double Rod Mini Cylinder MGD20X100 FAQ
Force is equal both directions: 131.9 N at 0.5 MPa and 184.7 N at 0.7 MPa, with a theoretical maximum of 26.9 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-800 mm/s, fluid air filtered to 40 um. Ports are 1/8" and the rod thread is M8x1.25 at both ends.
The MGD20X100 has a rod exiting both covers, so force is identical extending and retracting, the through-rod resists rotation and side load, and the rear end can carry a flag or a second load; the single-rod MG has a larger push than pull and no rear rod. This model has no magnet, so no sensor can be mounted; order the S version to fit CMSG, DMSG or EMSG switches. Note the fixed bumper pad only softens stroke ends and will not hold a load on air loss.
