About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X25S
The AirTAC MGCD50X25S is a double acting, double rod JIS round-body mini cylinder with a 50 mm bore and a short 25 mm stroke, built with a variable air cushion at both ends. Because a 20 mm rod exits both covers with the same M18x1.5 male thread, the piston works on the rod-side area in each direction, so the output force is equal both ways: 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. As a rule of thumb, size the working load at roughly 0.6 of the push force, which gives a safe vertical figure of about 50 kg for this cylinder. The adjustable cushion decelerates the piston smoothly at each end, so it can run faster or carry heavier loads than an unbuffered mini cylinder.
Construction follows the JIS mini-cylinder footprint with a riveted SUS304 stainless barrel and hard-chrome plated carbon-steel rods for corrosion resistance and long seal life. Air supply should be filtered to 40 um; operating pressure is 0.15-1.0 MPa (22-145 psi) with a proof pressure of 1.5 MPa (215 psi), temperature range -20 to +70 C, and speed range 30-800 mm/s. Ports are 1/4" with PT thread. The S code means a magnet is fitted, so CMSG, DMSG or EMSG switches can be mounted for position detection. Mounting options are FA flange or LB foot, with I and Y rod knuckles available.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X25S Is Used
High-speed anti-rotation transfer
The through-rod resists rotation while the variable air cushion absorbs the stop, letting a 50 mm bore shuttle parts between fixtures at speed without end-of-stroke slam.
Twin-load press with soft stop
Rod ends on both covers let you tool up two workpieces at once with about 824.3 N each way at 0.5 MPa, while the adjustable cushion gives a gentle landing on delicate assemblies.
Rear-switch slide
The rear rod end carries a stop flag or second load while the fitted magnet drives CMSG/DMSG/EMSG switches, giving position feedback on a compact 25 mm stroke slide.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X25S the Right Cylinder?
Choose the MGCD50X25S when you need equal force in both directions, anti-rotation guidance from a through-rod, and smooth high-speed stops from an adjustable cushion at both ends. At 824.3 N per side at 0.5 MPa it sits in the upper-middle of the MGCD range (bores 20 to 63 mm); step down to bore 32 or 40 for lighter loads or up to bore 63 for the largest thrust. If you need a double-rod cylinder with a fixed bumper instead of an air cushion in bores 20-40, look at the MGD; if a single rod with a cushion is enough, the MGC is the equivalent single-rod type. Order FA flange or LB foot mounting to suit the machine frame, add I or Y knuckles for pivoting rod attachments, and keep the S code if you need CMSG/DMSG/EMSG switch position feedback. For long strokes, support the rod to limit side loading; note that the cushion decelerates the stroke end only and does not lock the load, so use an external rod lock or pilot check valve where holding on air loss matters. Maximum standard stroke for this bore is 500 mm.

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 MGCD50X25S FAQ
Because both sides of the piston see the rod-side area, output is equal in both directions: 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 air must be filtered to 40 um.
The MGCD50X25S has a variable air cushion at each end that you adjust to decelerate the piston for smooth high-speed stops; it is not a fixed bumper pad and it does not lock or hold the load on air loss, so add an external rod lock or pilot check valve if holding is required. The double rod exits both covers, giving equal force both ways and a rear rod end for a stop, flag or second load. The MGD is the double-rod type with a fixed bumper (bores 20-40 only), and the MGC is the single-rod cushioned version. The S code on this model means a magnet is fitted for CMSG, DMSG or EMSG switches.
