About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD20X100
The MGCD20X100 is a double acting, double-rod JIS mini cylinder with a 20 mm bore and 100 mm stroke. A rod exits both covers with the same M8x1.25 male thread at each end, so the piston pushes on the rod-side area in both directions and delivers an equal 131.9 N at 0.5 MPa (184.7 N at 0.7 MPa) whichever way it moves. A variable air cushion at both ends lets you dial in smooth deceleration for higher speeds or heavier loads, and the through-rod gives natural anti-rotation plus a rear rod end for a stop flag or a second load. As a rule of thumb at 0.6 of the push force, plan on about 8 kg of horizontal working load, or roughly 6 kg if the cylinder lifts a vertical figure.
Construction follows the JIS round-body mini format: a riveted SUS304 stainless barrel with hard-chrome plated 8 mm rods for corrosion resistance and long seal life. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), tolerates 1.5 MPa (215 psi) proof pressure, works from -20 to +70 C, and covers 30-800 mm/s. Ports are M5x0.8, mounting is FA flange or LB foot with I and Y rod knuckles, and the standard stroke range for this bore reaches 300 mm. Note that the cushion only decelerates the stroke ends; it is not a lock, so use an external rod lock or pilot check valve if the load must be held on air loss.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD20X100 Is Used
High-speed anti-rotation transfer
The through-rod keeps the carried part from twisting while the variable air cushion at each end absorbs the stop, letting a 20 mm double-rod cylinder cycle small panels or carriers at speed without hard metal contact.
Twin-load press with soft stop
With 131.9 N available at each rod end at 0.5 MPa, one MGCD20X100 can press or seat two light workpieces simultaneously, and the adjustable cushion gives a gentle landing instead of a bang.
Rear-switch slide
Use the rear rod end to drive a cam or flag past a position switch while the front rod does the work, turning the 100 mm stroke into a compact, cushioned slide with integrated feedback.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD20X100 the Right Cylinder?
Size the MGCD20X100 when your load needs up to about 8 kg of working force in BOTH directions with a cushioned stop at each end; step up to MGCD25 or MGCD32 for heavier duty. If you need a double-rod cylinder at this bore without adjustable cushioning, the MGD (fixed bumper) covers bores 20-40, and the MGC is the single-rod cushioned alternative. Choose the -S suffix if you want position detection with CMSG, DMSG or EMSG switches; without the magnet no sensor can be fitted. Mount with FA flange or LB foot, add an I or Y knuckle on the rod ends, and keep side loads low on strokes approaching the 300 mm standard maximum.

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 MGCD20X100 FAQ
Because the rod-side area is active in both directions, output is equal both ways: 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, and the fluid is air filtered to 40 um.
The variable air cushion at both ends is adjusted with needles to decelerate the piston smoothly at each stroke end; it is not a brake and will not hold the load on air loss, so add an external rod lock or pilot check valve for that. The double rod gives equal force both directions and anti-rotation. Order the -S option to fit CMSG, DMSG or EMSG magnetic switches; this non-S model has no magnet, so no sensor can be mounted.
