About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X25S
The AirTAC MGCD63X25S is a double acting, double-rod JIS round-body mini cylinder with a 63 mm bore and 25 mm stroke. A rod exits both covers with the same M18x1.5 male thread at each end, and because both chambers see the rod-side area the output force is equal in both directions: about 1400.9 N at 0.5 MPa and 1961.2 N at 0.7 MPa, with a theoretical maximum of 285.7 kgf at 1.0 MPa. At 0.5 MPa that is roughly 142 kgf, so a realistic working load is about 85 kg for vertical lifting at the usual 0.6 safety factor. A variable air cushion at both ends decelerates the piston smoothly, letting this cylinder run at higher speeds and carry heavier loads than an unbuffered equivalent.
Construction follows the JIS mini-cylinder footprint with a riveted SUS304 stainless barrel and hard-chrome plated 20 mm carbon-steel rods for corrosion resistance and low wear. The two-way lubricant-storing piston seal extends service life, operating pressure spans 0.15-1.0 MPa (22-145 psi) with a proof pressure of 1.5 MPa (215 psi), and the speed range is 30-800 mm/s over -20 to +70 C. The S code means a magnet is fitted, so CMSG, DMSG or EMSG reed switches can be clipped on for end-of-stroke detection. Ports are 1/4" with PT thread, and mounting options are LB foot or FA flange plus I and Y rod knuckles.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X25S Is Used
High-speed anti-rotation transfer
The through-rod keeps the toolplate from twisting while the variable air cushion at each end absorbs the stop, letting a 1400.9 N push-pull cycle run faster than an unbuffered cylinder could survive.
Twin-load press with soft stop
Rod ends front and rear each carry a load, and the adjustable cushion eases both into position gently, ideal for light forming or staking at this 63 mm force class.
Magnet-sensed reciprocating slide
The fitted magnet and CMSG/DMSG/EMSG switches confirm each end of the 25 mm stroke, while the rear rod end drives a flag or counter mechanism on the same motion.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X25S the Right Cylinder?
Choose the MGCD63X25S when you need the largest cushioned double-rod mini cylinder in the MG family: 63 mm bore delivering 1400.9 N equally in both directions over a short 25 mm stroke. If your load needs more travel, this bore takes standard strokes up to 500 mm. For a double-rod cylinder with a fixed bumper pad instead of an adjustable cushion at 20-40 mm bores, look at the MGD; for a single-rod cushioned cylinder, the MGC is the match. The through-rod resists rotation and gives you a rear rod end for a stop, flag or second load. Order LB foot or FA flange mounting, I or Y knuckles on the rod, and remember the fitted magnet already supports CMSG/DMSG/EMSG switches. Note the air cushion only decelerates the stroke ends; it does not lock the load, so add an external rod lock or pilot check valve where holding is required, and support long strokes to avoid side loading.

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 MGCD63X25S FAQ
Because both chambers see the rod-side area, output is equal both ways: 1400.9 N at 0.5 MPa and 1961.2 N at 0.7 MPa, with a theoretical maximum of 285.7 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), speed range is 30-800 mm/s, temperature is -20 to +70 C, and the fluid is air filtered to 40 um. Ports are 1/4" PT.
The MGCD has an adjustable air cushion at both ends that decelerates the piston for smooth high-speed stops; the MGD uses fixed bumper pads instead, and the MGC is a single-rod cushioned cylinder. The double rod gives equal force in both directions and anti-rotation. This S-coded model carries a magnet, so CMSG, DMSG or EMSG reed switches mount directly for position detection. The cushion does not hold the load on air loss, so use an external rod lock or check valve where holding matters.
