About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X40S
The AirTAC MGCD50X40S is a double acting, double-rod JIS mini cylinder with a 50 mm bore and 40 mm stroke. A hard-chrome rod exits both covers with the same M18x1.5 male thread at each end, so the rod-side area is effective in both directions and the output force is equal either way: about 824.3 N at 0.5 MPa and 1154 N at 0.7 MPa, with a theoretical maximum of 168.1 kgf at 1.0 MPa. A variable air cushion at both ends lets you tune the deceleration for smooth stops at higher speeds or with heavier loads, and the rear rod end can carry a position flag, stop or a second load.
Built on a riveted round body with a SUS304 stainless barrel and hard-chrome carbon-steel rod, this 50 mm bore unit accepts 1/4" ports and runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), with a proof pressure of 1.5 MPa (215 psi), a temperature range of -20 to +70 C and speeds of 30-800 mm/s. The fitted magnet (S code) enables CMSG, DMSG or EMSG switches for end-of-stroke sensing. For a realistic working load, size around 0.6 of the push force, which gives a safe vertical figure of roughly 50 kg for this cylinder.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X40S Is Used
High-speed anti-rotation transfer
The through-rod resists rotation while the variable air cushion at both ends absorbs the energy of fast 30-800 mm/s transfers, letting the 50 mm bore deliver 824.3 N each way without hard metal stops.
Twin-load press with soft stop
Rod ends on both covers let this cylinder press or clamp two points at once with equal 824.3 N force at 0.5 MPa, while the adjustable cushion gives a smooth, controlled landing on light forming or marking tasks.
Rear-switch slide
The fitted magnet and rear rod end suit short-stroke slides where CMSG/DMSG/EMSG switches confirm position and the rear rod carries a flag or stop, with the cushion damping each reversal at up to 800 mm/s.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X40S the Right Cylinder?
Choose the MGCD50X40S when you need equal force in both directions on a short 40 mm stroke, adjustable cushioning at each end, and anti-rotation or a second rod-end function. At 824.3 N per side at 0.5 MPa, this 50 mm bore sits near the top of the MGCD range; step up to bore 63 (1400.9 N) for heavier duties or down to bore 40 (527.8 N) to save space. If you need a double-rod cylinder with a fixed bumper instead of an adjustable cushion in bores 20-40, look at the MGD; for a single rod with a cushion, the MGC is the match. Mount with the FA flange or LB foot and add I or Y rod knuckles; the fitted magnet supports CMSG/DMSG/EMSG switches. For long strokes or side loads, guide the load externally rather than relying on the rod.

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 MGCD50X40S FAQ
Because the rod-side area works in both directions, output is equal either way: 824.3 N at 0.5 MPa and 1154 N at 0.7 MPa, with a theoretical maximum of 168.1 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 fluid is air filtered to 40 um. Ports are 1/4" and the maximum standard stroke for this 50 mm bore is 500 mm.
The adjustable air cushion at both ends decelerates the piston near each stroke end for smooth high-speed stops; it is not a lock, so use an external rod lock or pilot check valve if the load must be held on air loss. The double rod exits both covers with the same M18x1.5 thread, giving equal force both ways and a rear rod for a flag or second load. The fitted magnet (S code) accepts CMSG, DMSG or EMSG switches. Unlike the MGD, which uses fixed bumpers, the MGCD cushion is adjustable, and unlike the single-rod MGC it delivers identical force in both directions.
