About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X25
The AirTAC MGCD50X25 is a JIS-standard round-body mini cylinder, double acting and double rod, with a variable air cushion at both ends. Because a 20 mm rod exits both covers with the same M18x1.5 male thread, both strokes see the rod-side area, so the output force is equal in each direction: 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. The adjustable cushion decelerates the piston smoothly at each end of the short 25 mm stroke, which suits higher speeds and heavier loads than a bumper pad would allow. As a rough rule of thumb, plan on about 60 percent of the push force for realistic working loads, which puts the safe vertical figure for this bore at roughly 50 kg.
Construction follows the JIS mini-cylinder footprint: a SUS304 stainless barrel with riveted, rolled covers and a hard-chrome plated carbon-steel rod, lubricated by a two-way storing piston seal. 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. Ports are 1/4" with PT thread. The rear rod end is free for a stop, flag, or a second load, and the through-rod gives natural anti-rotation. Mounting is FA flange or LB foot, with I and Y rod knuckles available; no sensor can be fitted unless the optional magnet (S code) is ordered, which then enables CMSG, DMSG, or EMSG switches.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X25 Is Used
High-speed anti-rotation transfer
The 25 mm stroke shuttles small fixtures between two positions at up to 800 mm/s, while the variable air cushion absorbs the stop at each end and the through-rod keeps the load from rotating, with 824.3 N available either way.
Twin-load press with soft stop
Both rod ends carry light pressing or marking tools working in opposition, and the adjustable cushion gives a smooth, non-shock landing on each part, backed by equal 1154 N force at 0.7 MPa in both directions.
Rear-switch slide
The rear rod end drives a flag or cam past CMSG, DMSG, or EMSG switches (with the S magnet option) while the front rod does the work, turning one short-stroke cylinder into a compact two-sided actuator.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X25 the Right Cylinder?
Size the MGCD50X25 by its equal both-way force of 824.3 N at 0.5 MPa: if your load in either direction needs more, step up to the bore 63 version (1400.9 N); if less, the bore 40 (527.8 N) or 32 (345.6 N) is more economical. Choose this model when you need a variable air cushion at both ends plus a through-rod for anti-rotation or a rear rod accessory; for a double-rod cylinder with a fixed bumper instead of an adjustable cushion in the smaller bores, look at the MGD (available bore 20-40), and for a single-rod cushioned cylinder choose the MGC. The 25 mm stroke is within the 500 mm maximum standard stroke for bore 50, so longer strokes are orderable without a nonstandard surcharge. Add the S code if you need position sensing with CMSG, DMSG, or EMSG switches, and pick FA flange or LB foot mounting with I or Y knuckles for the rod side. For long strokes with side loads, add external guidance; note that the cushion only decelerates the stroke end and does not lock the piston, so use an external rod lock or pilot check valve where load holding on air loss matters.

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 MGCD50X25 FAQ
Because it is a double-rod cylinder, the force 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. It runs double acting on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), withstands a proof pressure of 1.5 MPa (215 psi), operates from -20 to +70 C, and reaches speeds of 30-800 mm/s. Ports are 1/4" PT, and the maximum standard stroke for this bore is 500 mm.
The cushion at each end is an adjustable air chamber that decelerates the piston smoothly just before the stroke end, so you can run higher speeds or heavier loads without hard impact; it is not a brake and will not hold the load if air is lost, 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, and unlike the single-rod MGC it has a rod exiting both covers, giving equal force both ways and a rear rod end for a stop, flag, or second load. Add the S magnet code if you want CMSG, DMSG, or EMSG position sensing.
