About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD20X125
The AirTAC MGCD20X125 is a double acting, double-rod JIS round-body mini cylinder with a 20 mm bore and 125 mm stroke. A rod exits both covers with the same M8x1.25 male thread at each end, so both strokes see the rod-side area and deliver an equal force of about 131.9 N each way at 0.5 MPa (184.7 N at 0.7 MPa, up to 26.9 kgf theoretical at 1.0 MPa). A variable air cushion at both ends lets you tune deceleration for smooth, high-speed stops instead of hard metal contact.
The SUS304 stainless barrel with a hard-chrome-plated 8 mm rod and riveted covers suits compact washdown-prone machinery, and the through-rod gives natural anti-rotation plus a rear rod end for a stop flag or a second light load. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, -20 to +70 C, and 30-800 mm/s speed on air filtered to 40 um. As a working rule, keep loads to roughly 8 kg of this cylinder's 0.5 MPa force; for a vertical lift figure, halve that again. Add the S magnet option if you later need CMSG, DMSG or EMSG switch sensing.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD20X125 Is Used
High-speed anti-rotation transfer
The through-rod keeps the load from twisting while the variable air cushion at each end absorbs 30-800 mm/s travel, ideal for small pick-and-place slides moving parts under about 8 kg.
Twin-load press with soft stop
Use both rod ends to press two light points at once, each seeing about 131.9 N at 0.5 MPa, with the adjustable cushions giving a smooth, non-shock seating at the bottom of the stroke.
Rear-switch slide
The rear rod end carries a cam flag for a switch or stop dog while the front rod does the work; add the -S magnet option and a CMSG or DMSG switch for end-of-stroke confirmation.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD20X125 the Right Cylinder?
Size by force, not bore: the MGCD20X125 is the smallest cushioned double-rod option at 131.9 N both ways at 0.5 MPa; step up to MGCD25 or MGCD32 if you need more. Choose MGCD over MGD when you need adjustable cushioning rather than a fixed bumper, and over MGC when you need a rod at both ends. Mount with LB foot or FA flange and add I or Y rod knuckles for off-axis loads (no SDB/CB on this series). Order the -S code if position sensing with CMSG/DMSG/EMSG switches is planned. At 125 mm the stroke is well inside the 300 mm maximum standard stroke for bore 20; keep side loads low on longer strokes and guide externally.

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 and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MGCD Stainless Steel Mini Air Cylinder MGCD20X125 FAQ
This double-rod, double-acting cylinder gives an equal 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 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-800 mm/s, and the air supply should be filtered to 40 um. Ports are M5x0.8 and the rod thread is M8x1.25 at both ends.
The cushion is an adjustable air chamber at each end that decelerates the piston near stroke end, so you can tune the stop for higher speeds or heavier loads; it is not a lock, so the load is not held on air loss and an external rod lock or pilot check valve is needed for holding. Unlike the MGD, which uses fixed bumper pads, the MGCD has this adjustable air cushion, and unlike the single-rod MGC it has a rod at both ends, giving equal force in both directions. The -S option adds a magnet for CMSG, DMSG or EMSG switches.
