About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD20X350
The AirTAC MGCD20X350 is a double acting, double rod JIS round-body mini cylinder with a 20 mm bore and a 350 mm stroke. A rod exits both covers with the same M8x1.25 male thread at each end, so the piston works on the rod-side area in both directions and delivers an equal 131.9 N each way at 0.5 MPa (184.7 N at 0.7 MPa, up to a theoretical 26.9 kgf at 1.0 MPa). Both ends carry a variable air cushion, adjustable to decelerate the piston smoothly for higher speeds and heavier loads. The 350 mm stroke exceeds the 300 mm standard maximum for this bore, so it is supplied as a non-standard, made-to-order length.
Construction follows the JIS mini-cylinder footprint: a riveted SUS304 stainless barrel with hard-chrome plated carbon steel rods and two-way lubricant-retaining piston seals. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof tested to 1.5 MPa (215 psi), from -20 to +70 C at 30-800 mm/s. As a practical rule of thumb, size the working load at about 0.6 of the push force, which for this bore means roughly 8 kg in a vertical application. Ports are M5x0.8; mounting is FA flange or LB foot with I and Y rod knuckles. The cylinder ships without a magnet, so position sensing with CMSG, DMSG or EMSG switches requires the optional -S code.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD20X350 Is Used
High-speed anti-rotation transfer
The through-rod resists rotation while the variable air cushions tame the stop, letting a 131.9 N push move small parts between stations at speed without bounce.
Twin-load press with soft stop
Both rod ends carry the same M8x1.25 thread, so two light pressing or marking loads can run off one cylinder, each ending on an adjustable cushion for a gentle finish.
Rear-switch slide (with -S)
The rear rod end drives a flag or cam past CMSG, DMSG or EMSG switches on the -S version, giving end-of-stroke confirmation on a long 350 mm slide.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD20X350 the Right Cylinder?
Choose the MGCD20X350 when you need a 20 mm bore through-rod cylinder with smooth, adjustable cushioning at both ends and equal force in both directions; the 350 mm stroke is a non-standard length made to order, since the standard maximum for this bore is 300 mm. If you only need a bumper-style double-rod cylinder without adjustable cushioning in the small bores, look at the MGD; if a single rod with a cushion is enough, the MGC covers that. For more force step up to the 25 mm or 32 mm bore; the 20 mm is the smallest in the range. Mount with the FA flange or LB foot and pair with I or Y rod knuckles. Note that the cushion decelerates the piston at stroke end but does not lock or hold the load on air loss, so add an external rod lock or pilot check valve where holding is required. Order the -S option if you plan to fit CMSG, DMSG or EMSG magnetic switches.

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 MGCD20X350 FAQ
It is a double acting, double rod JIS mini cylinder, 20 mm bore and 350 mm stroke (non-standard, above the 300 mm standard maximum). Force 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, port M5x0.8, rod thread M8x1.25 at both ends.
The variable air cushion at each end is adjusted with a needle to decelerate the piston for smooth stops; it is not a fixed bumper pad and not a lock, so use an external check valve or rod lock to hold a load. Because a rod exits both covers, the rod-side area works in both directions and force is equal each way. The standard unit has no magnet, so order the -S option to mount CMSG, DMSG or EMSG switches. Unlike the MGD (double rod with bumper) or the single-rod MGC, the MGCD combines the through-rod with adjustable cushioning.
