About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X175S
The AirTAC MGCD63X175S is a JIS-standard round-body mini cylinder, double acting, with a double rod that exits both covers on the same M18x1.5 male thread. Because both sides of the piston see the rod-side area, the output force is equal in both directions: about 1400.9 N each way at 0.5 MPa and 1961.2 N each way at 0.7 MPa, with a theoretical maximum of 285.7 kgf at 1.0 MPa. A variable air cushion at both ends decelerates the piston smoothly, so this 63 mm bore can be run at higher speeds or carry heavier loads without hard metal-to-metal stops. The rear rod end can drive a second load or carry a stop flag, and the through-rod gives natural anti-rotation for guided work.
Practically, treat about 840 N (roughly 85 kg) as a realistic working force at 0.5 MPa, which halves to about 43 kg for a safe vertical lift. Construction matches the JIS mini-cylinder footprint: a riveted SUS304 stainless barrel, a hard-chrome plated 20 mm rod, and a two-way lubricant-storing piston seal. Operating range is 0.15-1.0 MPa (22-145 psi) with proof pressure of 1.5 MPa (215 psi), air filtered to 40 um, -20 to +70 C, and speeds of 30-800 mm/s. The fitted magnet (S code) accepts CMSG, DMSG or EMSG switches, and ports are 1/4" on both covers.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X175S Is Used
High-speed anti-rotation transfer
The through-rod resists load rotation while the variable air cushion lets the 63 mm bore shuttle pallets at the top of the 30-800 mm/s range and stop smoothly at each end of the 175 mm stroke.
Twin-load press with soft stop
Both rod ends drive loads simultaneously with equal force, about 1400.9 N each way at 0.5 MPa, while the adjustable cushions absorb the final approach so light forming or staking operations do not slam home.
Rear-switch reciprocating slide
The fitted magnet and rear rod end support CMSG or DMSG switch positioning and a stop flag, giving a cushioned reciprocating slide with position feedback at both ends of travel.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X175S the Right Cylinder?
Size the MGCD by force, not bore alone: at 1400.9 N per direction at 0.5 MPa this is the largest cushioned double-rod mini cylinder in the range, so step down to 50 mm (824.3 N) or 40 mm (527.8 N) if your load is lighter, and remember the equal-force rule when comparing with single-rod cylinders that quote a larger push figure. If you need a double-rod cylinder with a fixed bumper pad instead of an adjustable cushion at 20-40 mm bores, choose the MGD; for a single rod with a variable cushion, the MGC is the equivalent. The 175 mm stroke is within the 500 mm standard range for this bore, so no nonstandard surcharge applies. Mount with the FA flange or LB foot and add I or Y rod knuckles where the load pivots; SDB and CB mounts are not offered. The S in the model code means the magnet is already fitted, so order CMSG, DMSG or EMSG switches separately if you need position feedback. For long strokes or side loads, use external guides since the rod bearings are not designed to carry bending moments.

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 MGCD63X175S FAQ
Because the double rod exposes the rod-side area on both sides, output is equal both ways: 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, and the air must be filtered to 40 um. Ports are 1/4" on both covers and the rod thread is M18x1.5 at each end.
The cushion is an adjustable air damper at both stroke ends that decelerates the piston for smooth stops at high speed or with heavy loads; it is not a lock, so the cylinder will not hold its position on air loss and an external rod lock or pilot check valve is recommended for load 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 ends with equal force in both directions. The S code means the magnet is fitted for CMSG, DMSG or EMSG switches.
