About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD32X125
The AirTAC MGCD32X125 is a JIS-standard round-body mini cylinder, double acting, with a double rod and a variable air cushion at both ends. A 12 mm hard-chrome rod exits both covers with the same M10x1.25 male thread each end, so the rod-side area is active in both directions and the output force is equal both ways: about 345.6 N at 0.5 MPa and 483.8 N at 0.7 MPa, with a theoretical maximum of 70.5 kgf at 1.0 MPa. The adjustable air cushion decelerates the piston smoothly at each stroke end, allowing higher travel speeds and heavier loads than an unbuffered cylinder, while the through-rod gives natural anti-rotation and a free rear rod end for a stop flag, position switch trigger, or a second load.
Construction follows the JIS mini-cylinder footprint with a riveted SUS304 stainless barrel and hard-chrome plated carbon-steel rods, sealed by two-way lubricant-storing piston seals. 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 1/8". A practical working rule: size the load at roughly 0.6 of the available force, so about 21 kgf per direction, or about 17 kgf for a safe vertical lift. Add the S code to fit CMSG, DMSG, or EMSG magnetic sensors; mounting options are LB foot and FA flange with I and Y rod knuckles.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD32X125 Is Used
High-speed anti-rotation transfer
The through-rod keeps the carried part from rotating while the variable air cushion lets the slide run at speed and stop smoothly at both ends, with 345.6 N available each way at 0.5 MPa.
Twin-load press with soft stop
Both rod ends can carry a load or anvil, and the adjustable cushion at each stroke end decelerates the press gently, protecting tooling in light marking or assembly work.
Rear-switch slide
The rear rod end carries a stop flag or, with the S magnet option, a CMSG/DMSG/EMSG switch, turning the 125 mm stroke into a position-signalling slide for indexing fixtures.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD32X125 the Right Cylinder?
Choose the MGCD32X125 when you need equal force in both directions, anti-rotation, and smooth cushioned stops in a compact JIS round body. At 345.6 N per direction at 0.5 MPa it sits mid-range in the MGCD family: step up to bore 40 (527.8 N) or 50 (824.3 N) for heavier loads, or down to bore 25 (206.1 N) for lighter duty. If you need a bumper-cushioned double-rod cylinder in bores 20-40, the MGD is the alternative; for a single rod with cushion, choose the MGC. The cushion is adjustable, not a lock: it only decelerates the stroke end, so for load holding on air loss add an external rod lock or pilot check valve. Mount with the LB foot or FA flange and pair with I or Y knuckle joints; specify the S code if you need CMSG/DMSG/EMSG position sensing. For strokes beyond the 500 mm maximum standard stroke of this bore, or for significant side loads, request guidance on guides and stroke options.

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 MGCD32X125 FAQ
Because both directions use the rod-side area, output is equal both ways: 345.6 N at 0.5 MPa and 483.8 N at 0.7 MPa, with a theoretical maximum of 70.5 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), fluid is air filtered to 40 um, working temperature -20 to +70 C, and speed range 30-800 mm/s. Ports are 1/8" and the rod thread is M10x1.25 on both ends.
The MGCD32X125 has an adjustable air cushion at both ends that decelerates the piston near each stroke end for smooth, high-speed stops; it is not a brake and will not hold the load on air loss, so use an external rod lock or pilot check valve for holding. Unlike the MGD, which uses fixed bumper pads, the MGCD cushion is adjustable. Unlike the single-rod MGC, the MGCD is a double-rod cylinder, so force is equal in both directions and the rear rod end is free for a flag, switch trigger, or second load. The optional S code magnet enables CMSG, DMSG, or EMSG sensors.
