About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X175
The AirTAC MGCD40X175 is a double acting, double rod JIS round-body mini cylinder with a 40 mm bore and 175 mm stroke. A rod exits both covers with the same M14x1.5 male thread each end, and because both sides of the piston see the rod-side area, the output force is equal in both directions: about 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa, with a theoretical maximum of 107.6 kgf at 1.0 MPa. A variable air cushion at each end decelerates the piston smoothly, so this cylinder suits higher speeds and heavier loads than an unbuffered mini cylinder. The through-rod also gives natural anti-rotation and a rear rod end you can use for a stop flag or a second load.
Construction follows the JIS mini-cylinder footprint with a riveted SUS304 stainless barrel and a hard-chrome plated 16 mm rod for long seal and bearing life. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), tolerates a proof pressure of 1.5 MPa (215 psi), operates from -20 to +70 C, and covers speeds of 30-800 mm/s. As a practical sizing rule, take about 0.6 of the push force, so plan on roughly 32 kg of working load, or about 26 kg if the cylinder lifts a vertical figure. Note that the cushion only slows the piston at each stroke 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.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X175 Is Used
High-speed anti-rotation transfer
The through-rod keeps the carried part from twisting while the variable air cushion absorbs the stop, letting the MGCD40X175 shift jigs or trays at speed with its 527.8 N equal push and pull.
Twin-load press with soft stop
Rod ends on both covers let one MGCD40X175 press two light parts at once, and the adjustable air cushion at each end gives a smooth, non-slamming approach at up to 738.9 N.
Rear-switch slide (with -S option)
On the -S version, the rear rod end carries a CMSG, DMSG or EMSG switch flag for end-of-stroke signalling on a slide or gate, while the cushion damps each reversal.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X175 the Right Cylinder?
Size the MGCD40X175 by force: at 527.8 N per direction at 0.5 MPa it sits mid-range in the MGCD line, above the 20/25/32 bores and below the 50/63. If you need more force, step up to MGCD50 or MGCD63; if 527.8 N is generous, MGCD32 saves space. If you want a double-rod cylinder at this bore without cushioning, that is the MGD (bumper, 20-40 only); if you want a single rod plus cushion, choose the MGC. This model has no magnet, so no CMSG/DMSG/EMSG switch can be fitted; order the -S code if you need position detection. Mount with the FA flange or LB foot and add I or Y rod knuckles on the loaded end; CB and SDB are not offered. The 175 mm stroke is well inside the 500 mm maximum standard stroke for this bore, but keep side loads low on long strokes and guide external mass separately.

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 MGCD40X175 FAQ
Because it is a double rod cylinder, the force is equal both ways: 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa, with a theoretical maximum of 107.6 kgf at 1.0 MPa. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), takes a proof pressure of 1.5 MPa (215 psi), operates from -20 to +70 C, and covers 30-800 mm/s. The 1/8" ports take PT thread on this model.
The MGCD40X175 has an adjustable air cushion at both ends that decelerates the piston near each stroke end for smooth stops at higher speed or load; 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 covers, so force is identical in both directions. Order the -S code if you need a CMSG/DMSG/EMSG sensor.
