About the Airtac MGD Double Rod Mini Cylinder MGD20X175S
The AirTAC MGD20X175S is a JIS round-body mini cylinder that is double acting with a double rod: a hard-chrome steel rod exits both the front and rear covers with the same M8x1.25 male thread at each end, so the two rod ends move together. Because the rod-side piston area is active in both directions, the output force is equal either way, about 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. The 8 mm through-rod resists rotation and side load, and the rear rod end can carry a stop flag or drive a second load while the front end does the work.
Built for long service in damp or washdown-prone areas, the 20 mm bore barrel is SUS304 stainless with riveted covers and a two-way lubricant-storing piston seal. A fixed anti-impact bumper pad softens each stroke end, though it is not an adjustable cushion and does not hold a load on air loss. The fitted magnet (the S code) allows CMSG, DMSG or EMSG switches to be mounted for end-of-stroke sensing, and the cylinder runs on filtered air at 0.15-1.0 MPa (22-145 psi), -20 to +70 C, at 30-800 mm/s. With a 175 mm stroke it sits comfortably inside the 300 mm standard stroke range for this bore.

Where the Airtac MGD Double Rod Mini Cylinder MGD20X175S Is Used
Anti-rotation slide
The 8 mm through-rod keeps a small carrier from rotating on a 175 mm transfer stroke, with 131.9 N available in whichever direction the slide moves.
Twin-load push
Drive two light fixtures or clamps at once, one from each M8x1.25 rod end, with equal 131.9 N force from both sides of the piston.
Rear-mounted stop flag
Use the back rod end to carry a switch or stop flag into a counting or inspection station while the front end does the pushing.
Is the Airtac MGD Double Rod Mini Cylinder MGD20X175S the Right Cylinder?
At 131.9 N per direction at 0.5 MPa, this is the smallest force class in the MGD range; bore 20 is the entry size, and bore 25 (206.1 N) or bore 32 (345.6 N) are the steps up if your load needs more. As a rule of thumb, size the cylinder at about 0.6 of its rated force, so keep the working load near 79 N (roughly 8 kg), or about 6.7 kg if the load hangs vertically. Choose the MGD20X175S when you need anti-rotation guidance, equal force both ways, or a rear rod end for a switch flag or twin load. If you need a single rod, look at the MG series; if you need bore 50/63 or an adjustable air cushion, the MGCD is the right family. Mount with LB foot or FA flange and add I or Y rod knuckles as needed (no SDB/CB pivots on double-rod models); the 1/8" port is the same on every MGD bore. At 175 mm stroke, support the rod or limit side load to protect the bearing at the stroke ends.

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 MGD20X175S FAQ
It delivers 131.9 N in each direction 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 is 1.5 MPa (215 psi), temperature range is -20 to +70 C, and speed is 30-800 mm/s on air filtered to 40 um.
The MGD has a rod exiting both covers, so force is equal both ways (the rod-side area works in both directions) and the through-rod resists rotation; the single-rod MG has a larger extend force than retract force. This S-coded model carries a magnet, so CMSG, DMSG or EMSG switches can be mounted on the barrel for position sensing.
