About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X450
The AirTAC MGCD63X450 is a double acting, double rod JIS round-body mini cylinder with a 63 mm bore and a 450 mm stroke, fitted with a variable air cushion at both ends. Because a 20 mm rod exits both covers with an M18x1.5 male thread on each end, both strokes work on the rod-side area, so the output is equal in both directions: about 1400.9 N at 0.5 MPa and 1961.2 N at 0.7 MPa, with a theoretical maximum of 285.7 kgf at 1.0 MPa. The adjustable cushion decelerates the piston smoothly at each end, letting this largest MGCD bore run faster cycles or carry heavier loads without hard metal-to-metal stops. Air supply is 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), speed range is 30-800 mm/s, and the fluid is air filtered to 40 um.
Construction follows the JIS mini-cylinder footprint: a riveted SUS304 stainless barrel with a hard-chrome-plated carbon steel rod for corrosion resistance and long seal life. The 450 mm stroke sits within the 500 mm maximum standard stroke for this bore, and the 1/4" ports keep flow adequate for high-speed travel. The rear rod end is free for a stop flag, position flag, or a second load, and the through-rod naturally resists rotation. Note that the cushion only slows the piston near each end; it is not a lock, so use an external rod lock or pilot check valve if the load must be held on air loss. This unit ships without a magnet, so no CMSG, DMSG, or EMSG switch can be fitted unless the optional S code is ordered.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X450 Is Used
High-speed anti-rotation transfer
The 63 mm through-rod moves pallets or fixtures over 450 mm at up to 800 mm/s while resisting rotation, and the variable air cushions bring each end to a smooth stop at 1400.9 N of force.
Twin-load press with soft stop
Both rod ends carry workpieces, so the same 1400.9 N acts on each side of the cycle, and the adjustable cushions at both ends absorb the impact of heavier loads without hard stops.
Rear-switch slide
The rear rod end drives a position flag or stop while the front end does the work; order the S code to fit CMSG or DMSG switches along the 450 mm stroke for end-of-travel signals.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X450 the Right Cylinder?
At 63 mm this is the largest MGCD bore, delivering about 1400.9 N each way at 0.5 MPa. A practical rule of thumb is to size for roughly 0.6 of that force, so plan on about 840 N of usable push, or roughly 85 kg as a safe vertical load. If your duty needs less force, step down to MGCD50 (about 824 N) or MGCD40 (about 528 N); if you need a bumper-style double-rod cylinder in smaller bores, the MGD covers 20-40 mm, and for a single rod with cushion the MGC is the equivalent. Choose the MGCD63X450 when you need equal force in both directions, anti-rotation from the through-rod, and adjustable deceleration at both ends of a long 450 mm stroke. Mount with the FA flange or LB foot, add I or Y rod knuckles for off-axis links, and order the S code if you want CMSG, DMSG, or EMSG magnetic switches. On a stroke this long, keep side loads low and use external guides to protect the rod bearings.

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 MGCD63X450 FAQ
Because the double-rod design works on the rod-side area in both directions, output is equal each way: 1400.9 N at 0.5 MPa and 1961.2 N at 0.7 MPa, with a theoretical maximum of 285.7 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), speed is 30-800 mm/s, temperature is -20 to +70 C, and the fluid is air filtered to 40 um.
The MGCD63X450 has an adjustable air cushion at both ends that decelerates the piston near each end of stroke for smooth stops at speed; 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. Unlike the MGD, which uses fixed bumper pads, the MGCD cushion is adjustable. Unlike the single-rod MGC, the MGCD has a rod at both ends, giving equal force both ways and a free rear rod end. The optional S code enables CMSG, DMSG, or EMSG magnetic switches.
