About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X500S
The AirTAC MGCD40X500S is a double acting, double-rod JIS mini cylinder with a 40 mm bore and a 500 mm stroke, fitted with a variable air cushion at both ends. Because a 16 mm rod exits both covers with the same M14x1.5 male thread each end, the piston works on the rod-side area in both directions, 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 adjustable cushion decelerates the piston smoothly at each end, letting this cylinder run at higher speeds or carry heavier loads than an unbuffered mini cylinder of the same bore.
The rear rod end doubles as a mounting point for a stop, flag or second load, and the through-rod resists rotation naturally. Construction is a riveted round-body barrel in SUS304 stainless steel with a hard-chrome plated rod, built to the JIS footprint. Operating range is 0.15-1.0 MPa (22-145 psi) with a proof pressure of 1.5 MPa (215 psi), temperature -20 to +70 C and speed 30-800 mm/s, on air filtered to 40 um. The fitted magnet (S code) accepts CMSG, DMSG or EMSG switches, and the 1/8" ports take PT thread. As a rule of thumb, size the working load at about 0.6 of the push force, roughly 316 N, which for a vertical lift means a safe figure of about 26 kg.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X500S Is Used
High-speed anti-rotation transfer
The through-rod keeps the tool plate from twisting while the variable air cushion absorbs the stop at 500 mm of travel, letting the 40 mm bore cycle faster than an unbuffered cylinder could survive.
Twin-load press with soft stop
Rod ends on both covers let the MGCD40X500S carry a workpiece fixture on one side and a flag on the other, with 527.8 N of equal force each way and a cushioned landing that protects delicate parts.
Rear-switch slide with position feedback
The fitted magnet and CMSG/DMSG/EMSG switches report both end positions on this long-stroke slide, while the adjustable cushion tames the deceleration of the moving carriage at each end.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X500S the Right Cylinder?
Choose the MGCD40X500S when you need a cushioned, double-acting mini cylinder whose force is equal in both directions and whose rear rod end can carry a stop, flag or second load. If 527.8 N per direction at 0.5 MPa is marginal for the application, step up to the MGCD50 for about 824 N; if it is generous, the MGCD32 gives about 346 N in a smaller body. For a bumper-cushioned double-rod cylinder in the 40 mm class, the MGD is the alternative, and for a single rod with a cushion the MGC applies. Mount with the FA flange or LB foot, add I or Y rod knuckles where the load pivots, and order the -S suffix (fitted here) when CMSG/DMSG/EMSG position sensing is required. At 500 mm, this is the maximum standard stroke for the 40 mm bore; keep side loads off the rod and guide the load externally on long strokes.

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 MGCD40X500S FAQ
Because the double-rod design exposes the rod-side area in both directions, output 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. 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 1/8" PT and the rod thread is M14x1.5 at both ends.
The cushion is an adjustable air buffer at both stroke ends that decelerates the piston for smooth, high-speed stops; it is not a lock, so an external rod lock or pilot check valve is needed to hold a load on air loss. Unlike the MGD, which uses fixed bumper pads, the MGCD has a tunable air cushion, and unlike the single-rod MGC it has a rod at both covers, giving equal force in both directions and a rear rod end for a stop or second load. The fitted magnet accepts CMSG, DMSG or EMSG switches.
