About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X75S
The AirTAC MGCD40X75S is a double acting, double-rod JIS round-body mini cylinder with a 40 mm bore and 75 mm stroke. Because a 16 mm hard-chrome rod exits both covers, the piston works on the rod-side area in each direction, so the output force is equal both ways: 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. The rear rod end can carry a second load, a stop flag or a position marker while the front rod does the main work, and the through-rod naturally resists rotation.
Unlike a fixed bumper pad, this MGCD variant carries a variable air cushion at both ends, so you can tune the deceleration for high-speed or heavier-load stops instead of accepting a hard hit. The SUS304 stainless barrel with riveted covers suits washdown-prone lines, and the fitted magnet (-S code) accepts CMSG, DMSG or EMSG switches for end-of-stroke sensing. Running on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), with a 1.5 MPa (215 psi) proof pressure and -20 to +70 C range, it moves at 30-800 mm/s. For a realistic working load, size around 0.6 of the push force, roughly 316 N; vertically that is about 26 kg per direction.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X75S Is Used
High-speed anti-rotation transfer
The through-rod keeps the toolplate from twisting while the variable air cushion absorbs the stop at 30-800 mm/s, so a 40 mm bore moving parts between stations lands smoothly without bang or drift.
Twin-load press with soft stop
Front rod presses while the rear rod end drives a second pad or counter-feature; equal 527.8 N force both ways at 0.5 MPa and adjustable cushioning give a matched, gentle bottom-out on light forming and marking jobs.
Rear-switch reciprocating slide
With the fitted magnet and CMSG/DMSG/EMSG switches on both rod ends, the MGCD40X75S cycles a short-stroke slide where the rear rod carries a flag for position confirmation and the cushion damps each reversal.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X75S the Right Cylinder?
Choose the MGCD40X75S when you need equal force in both directions, a through-rod for anti-rotation or a second rod end, and adjustable cushioning at each stop. At 40 mm bore it delivers 527.8 N each way at 0.5 MPa; step up to bore 50 or 63 for heavier loads, or down to bore 20, 25 or 32 for lighter duty. If you want a double-rod cylinder with a fixed bumper instead of an adjustable cushion, look at the MGD (bores 20-40); if a single rod plus cushion is enough, the MGC is the equivalent single-rod build. Mount with the LB foot or FA flange and add I or Y rod knuckles for off-axis loads; SDB and CB mounts are not offered. The -S magnet in this model enables CMSG/DMSG/EMSG sensing. Keep side loads off the rod on longer strokes and guide the load externally; note the cushion only decelerates the stroke ends and does not hold position on air loss, so use an external rod lock or pilot check valve where holding is required.

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 MGCD40X75S FAQ
Because it is a double-rod cylinder, force is equal in both directions: 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 is double acting, runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), tolerates a 1.5 MPa (215 psi) proof pressure, operates from -20 to +70 C, and travels at 30-800 mm/s. The 40 mm bore takes a 1/8" port and an M14x1.5 male rod thread on both ends.
The cushion at each end is an adjustable air damper: you tune the orifice to decelerate the piston smoothly for high speeds or heavier loads, unlike the fixed bumper pad on the MGD. Because the MGCD is a double-rod design, force is identical both ways and the rear rod end is free for a second load or switch flag, while the MGC is a single-rod cushioned cylinder with a larger push than pull force. The fitted magnet on this -S model also allows CMSG, DMSG or EMSG position switches.
