About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD32X125S
The AirTAC MGCD32X125S is a double acting, double rod JIS mini cylinder with a 32 mm bore and 125 mm stroke. Because a rod exits both covers with the same M10x1.25 male thread, the piston sees the rod-side area in either direction, so output is equal both ways: about 345.6 N at 0.5 MPa and 483.8 N at 0.7 MPa. A variable air cushion at each end lets you tune deceleration for smooth, high-speed stops, and the rear rod end can carry a second load, a stop plate or a position flag. The fitted magnet (the S code) allows CMSG, DMSG or EMSG reed switches to be clipped on for end-of-stroke signalling.
Construction follows the JIS round-body mini format: a riveted SUS304 stainless barrel with hard-chrome plated carbon steel rods and a two-way lubricant-storing piston seal. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), withstands a 1.5 MPa (215 psi) proof pressure, operates from -20 to +70 C, and travels at 30-800 mm/s. As a rule of thumb, plan on about 60 percent of the push force for a realistic working load, which for this bore means roughly 21 kg safe vertical load at 0.5 MPa.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD32X125S Is Used
High-speed anti-rotation transfer
The through-rod resists load rotation while the variable air cushion absorbs the stop, letting this 345.6 N cylinder index trays or carriers on a conveyor line faster than an uncushioned mini cylinder.
Twin-load press with soft stop
Rod ends on both covers each carry a light pressing or marking tool, so the 32 mm bore applies about 345.6 N per side at 0.5 MPa and the adjustable cushion eases the tools into contact without impact.
Switched slide with rear flag
The rear rod end drives a position flag past CMSG or DMSG switches (enabled by the fitted magnet) on a fixture slide, while the cushions give repeatable, jolt-free seating at both ends of the 125 mm stroke.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD32X125S the Right Cylinder?
Size the MGCD up or down by force: bore 32 delivers 345.6 N each way at 0.5 MPa, sitting between the 25 (206.1 N) and 40 (527.8 N) in the cushioned double-rod range, which spans 20 to 63 mm. Choose the MGCD when you need equal force in both directions, anti-rotation guidance from the through-rod, or adjustable cushioning at both ends; if you only need a bumper-padded double-rod cylinder in 20-40 mm, look at the MGD, and for a single rod with cushion the MGC is the match. The 125 mm stroke is within the 500 mm standard range for this bore. Mount with the LB foot or FA flange (CB and SDB are not offered), add I or Y rod knuckles on the loaded end, and note the -S magnet is already fitted so CMSG/DMSG/EMSG switches can be added. Keep side loads off the rod on long strokes and use an external rod lock or pilot check valve if the load must be held on air loss, since the cushion only decelerates the stroke end.

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 MGCD32X125S FAQ
With its double rod design the force is equal both directions: 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. It runs double acting on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), tolerates a 1.5 MPa (215 psi) proof pressure, works from -20 to +70 C, and reaches speeds of 30-800 mm/s. The 1/8" ports take PT thread and the rod thread is M10x1.25 on both ends.
The MGCD32X125S has a variable air cushion at both ends, so you adjust the needle to control deceleration for smooth stops at speed or with heavier loads; it is not a fixed bumper pad and not a lock, so use an external rod lock or pilot check valve to hold a load on air loss. The rod exits both covers, giving equal force both ways and a spare rear rod end for a flag or second load. The MGD is a double-rod cylinder with fixed bumpers instead of adjustable cushions, and the MGC is a single-rod cushioned cylinder, so its push and pull forces differ. The fitted magnet also accepts CMSG, DMSG or EMSG switches.
