About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X200S
The AirTAC MGCD50X200S is a JIS-standard round-body mini cylinder, double acting and double rod, with a variable air cushion at both ends. A 20 mm rod exits each cover with the same M18x1.5 male thread, so the rod-side area is pressurized in both directions and the output force is equal either way: about 824.3 N at 0.5 MPa and 1154 N at 0.7 MPa, with a theoretical maximum of 168.1 kgf at 1.0 MPa. Because both rod ends move together, the exposed rear rod gives you a natural mounting point for a position flag, stop or second light load, and the through-rod resists rotation. The adjustable cushion decelerates the piston smoothly at each end of the 200 mm stroke, letting you run faster cycles with heavier tooling than an unbuffered cylinder could handle.
Construction follows the JIS mini-cylinder footprint: a SUS304 stainless barrel with riveted covers and hard-chrome-plated carbon steel rods for long seal and bearing life. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, -20 to +70 C, and speeds of 30-800 mm/s. The fitted magnet (the S in the model code) accepts CMSG, DMSG or EMSG switches for end-of-stroke signaling. A practical sizing rule: keep the working load near 0.6 of the push force, so about 494 N, roughly 50 kg horizontally or about 25 kg as a safe vertical figure at 0.5 MPa.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X200S Is Used
High-speed anti-rotation transfer
The through-rod keeps the toolplate from twisting while the variable air cushion brings the 200 mm stroke to a smooth stop at both ends, letting the 824.3 N (0.5 MPa) slide move pallets faster than an unbuffered cylinder.
Twin-load press with soft stop
Equal force both ways plus a rear rod end lets one MGCD50X200S drive a forming die on the front rod while the back rod carries a return flag, with adjustable cushioning absorbing the impact at the bottom of the stroke.
Rear-switch reciprocating slide
The fitted magnet works with CMSG/DMSG/EMSG switches on either cover, and the rear rod carries a cam flag, so the 1154 N (0.7 MPa) bidirectional stroke reports position without external brackets.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X200S the Right Cylinder?
Choose the MGCD50X200S when you need equal force in both directions, anti-rotation guidance and cushioned high-speed stops in a 50 mm bore: its 824.3 N at 0.5 MPa each way suits medium-duty transfer and press fixtures. Step down to MGCD40 for lighter loads or up to MGCD63 (1400.9 N at 0.5 MPa) when the force margin is tight. If you need a double-rod cylinder in bores 20-40 without cushioning, the MGD with fixed bumpers is the lighter alternative; for a single-rod cushioned cylinder, pick the MGC instead. Mount with the FA flange or LB foot, add I or Y rod knuckles for off-axis links (SDB and CB are not offered), and remember the variable air cushion only decelerates the stroke ends - it does not lock the piston, so fit an external rod lock or pilot check valve if the load must hold on air loss. The 200 mm stroke is within the 500 mm maximum standard stroke for this bore, and the -S magnet enables CMSG/DMSG/EMSG position sensing.

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 MGCD50X200S FAQ
Because the double-rod design pressurizes the rod-side area in both directions, output is equal either way: 824.3 N at 0.5 MPa and 1154 N at 0.7 MPa, with a theoretical maximum of 168.1 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), the fluid is air filtered to 40 um, temperature range is -20 to +70 C, and speed is 30-800 mm/s. The bore is 50 mm with a 20 mm rod, M18x1.5 male thread on both rod ends and 1/4" ports.
The MGCD50X200S has an adjustable air cushion at both ends that decelerates the piston near each stroke end, so you can run higher speeds and heavier loads without hard impact; it is not a lock, so use an external rod lock or pilot check valve if the load must hold on air loss. Unlike the MGD, which is a double-rod cylinder with fixed bumper pads in bores 20-40, the MGCD offers a tunable cushion and extends to bores 50 and 63. Unlike the single-rod MGC, the MGCD's through-rod gives equal force in both directions, anti-rotation and a rear rod end for a flag or second load. The fitted magnet also accepts CMSG, DMSG or EMSG switches.
