About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD20X100S
The AirTAC MGCD20X100S is a double acting, double rod JIS round-body mini cylinder with a 20 mm bore and 100 mm stroke. Because a rod exits both covers with the same M8x1.25 male thread at each end, both sides of the piston see the rod-side area, so the output force is equal in both directions: 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. Using the common rule of thumb that a safe working load is roughly 0.6 of the push force, plan on about 8 kg horizontally, or about 6 kg if the cylinder carries a vertical load. The rear rod end can drive a stop, flag or second load while the front rod does the work.
This variant carries a variable air cushion at both ends, adjustable so the piston decelerates smoothly into each cover for higher-speed or heavier-duty stops, and the through-rod gives natural anti-rotation guidance. The barrel is SUS304 stainless with a hard-chromed carbon-steel rod, riveted covers and a two-way lubricant-storing piston seal, built to the JIS mini-cylinder footprint. Operating pressure is 0.15-1.0 MPa (22-145 psi) with proof pressure of 1.5 MPa (215 psi), temperature range -20 to +70 C, and speed 30-800 mm/s on air filtered to 40 um. The fitted magnet (S code) allows CMSG, DMSG or EMSG switches, and the M5x0.8 port suits compact manifolding.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD20X100S Is Used
High-speed anti-rotation transfer
The through-rod keeps small carriers square during fast push-pull moves, while the variable air cushion at both ends lets the 131.9 N both-way force run at speed without hard cover impacts.
Twin-load light press with soft stop
Drive two light press or clinch points from the same cylinder: the front rod works the tool and the rear rod a counter fixture, each direction delivering equal force with a cushioned, gentle seating.
Rear-switch slide with position flags
Mount CMSG or DMSG switches on the magnet and use the rear rod end to carry a trigger flag, giving a compact 100 mm stroke slide with smooth cushioned end positions and clean signal timing.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD20X100S the Right Cylinder?
Size the MGCD20X100S by its equal both-way force: 131.9 N at 0.5 MPa is the smallest cushioned MG-family bore, so step up to MGCD25 or MGCD32 if your load needs more. Choose this double-rod build when you need equal force in both directions, anti-rotation guidance, or a rear rod end for a stop or second load; if you only need a bumper-ended double-rod cylinder in this bore range, look at the MGD, and for a single rod with a cushion use the MGC. The variable air cushion at both ends smooths high-speed stops, but it only decelerates the piston and does not lock it: the MGCD20X100S will not hold its position on air loss, so add an external rod lock or pilot check valve for load holding. Mounting is FA flange or LB foot, with I and Y rod knuckles available (no CB or SDB options), and the fitted magnet supports CMSG, DMSG or EMSG position sensing. The maximum standard stroke for this bore is 300 mm, so 100 mm is comfortably standard; for long strokes watch side load on the 8 mm rod and guide the load 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 MGCD20X100S FAQ
Because it is a double rod cylinder, the force is equal in 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, on air filtered to 40 um. The port is M5x0.8 and the rod thread is M8x1.25 at both ends.
The MGCD20X100S has an adjustable air cushion at both ends that decelerates the piston smoothly into each cover, allowing higher speeds and heavier loads than an un cushioned stop. It is not a lock: the cylinder will not hold its load on air loss, so use an external rod lock or pilot check valve for holding. Unlike the MGD, which is a double-rod cylinder with fixed bumper pads, the MGCD uses a variable air cushion; unlike the MGC, which is single rod, the MGCD's through-rod gives equal force both ways and a rear rod end. The fitted magnet accepts CMSG, DMSG or EMSG switches.
