About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X175
The AirTAC MGCD63X175 is a JIS-standard round-body mini cylinder, double acting and double rod, with a variable air cushion at both ends. Because a 20 mm rod exits both covers with the same M18x1.5 male thread, both strokes see the rod-side area, so the output force is equal in each direction: 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 MG-family bore run at higher speeds or carry heavier loads without hard stops, while the rear rod end can carry a second load, a stop flag or a position marker.
Construction follows the JIS mini-cylinder footprint: a riveted SUS304 stainless barrel with hard-chrome plated carbon-steel rods and two-way lubricant-storing 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. A practical working rule: size loads at about 0.6 of the push force, so roughly 85 kg is a safe vertical figure for this cylinder. The 1/4" ports, LB foot and FA flange mounting, and I and Y rod knuckles cover typical installations; add the S code if you later need CMSG, DMSG or EMSG switch sensing.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X175 Is Used
High-speed anti-rotation transfer
The through-rod resists rotation while the variable air cushion absorbs the stop at 175 mm of travel, letting a 63 mm bore move heavy fixtures at speed without end-of-stroke impact.
Twin-load press with soft stop
Rod ends on both covers each deliver about 1400.9 N at 0.5 MPa, so two small pressing or staking points can run from one cylinder, with the adjustable cushion giving a gentle final approach.
Rear-switch slide
The rear rod end carries a flag or stop block while the main rod drives the slide; order the -S magnet option to fit CMSG or DMSG switches for end-of-stroke confirmation.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X175 the Right Cylinder?
At 63 mm bore this is the largest MGCD, delivering 1400.9 N each way at 0.5 MPa; step down to 50, 40, 32, 25 or 20 mm if your load needs less force. Choose the MGCD when you need equal force in both directions plus smooth, adjustable deceleration at both stroke ends. If you want a double-rod cylinder with a fixed bumper instead of an air cushion in the smaller 20-40 mm range, look at the MGD; for a single-rod cushioned cylinder, the MGC is the equivalent. The cushion decelerates the piston but does not lock it: the MGCD will not hold a load on air loss, so add an external rod lock or pilot check valve for holding. Mount with the LB foot or FA flange and pair with I or Y rod knuckles; SDB and CB are not offered. Order the -S option if you plan to fit CMSG, DMSG or EMSG magnetic switches. For strokes beyond the 500 mm standard maximum on this bore, or for heavy side loads, request guidance on guides and supports.

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 MGCD63X175 FAQ
Because it is a double-rod cylinder, force is equal in both directions: 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 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-800 mm/s, on air filtered to 40 um. Ports are 1/4" and the rod thread is M18x1.5 on both ends.
The MGCD63X175 has an adjustable air cushion at both ends that decelerates the piston near each stroke end, allowing higher speeds and heavier loads than a hard 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 uses fixed bumper pads, the MGCD cushion is adjustable; unlike the single-rod MGC, the MGCD has a rod at both covers, giving equal force both ways and a rear rod end for a stop, flag or second load. Add the S code to fit CMSG, DMSG or EMSG switches.
