About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X350S
The AirTAC MGCD63X350S is a double acting, double rod JIS-standard round-body mini cylinder with a 63 mm bore and 350 mm stroke. A hard-chrome rod exits both covers with the same M18x1.5 male thread at each end, so the rod-side area is effective in both directions and the output force is equal either way: 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. A variable air cushion at both ends lets you tune the deceleration at each stroke end, so the piston can run at up to 800 mm/s and stop smoothly under higher speed or heavier loads. The fitted magnet (the S code) allows CMSG, DMSG or EMSG switches to be mounted directly on the SUS304 stainless barrel.
As a practical sizing rule, take about 0.6 of the push force for a realistic working load, which gives roughly 85 kg as a safe vertical figure for this cylinder. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, on air filtered to 40 um, across a temperature range of -20 to +70 C. The riveted round-body construction uses a SUS304 stainless barrel with a hard-chrome (20 um) carbon-steel rod and a two-way lubricant-storing piston seal. Mounting is via FA flange or LB foot, with I and Y rod knuckles available; ports are 1/4". Note that the cushion only decelerates the stroke ends and does not lock the piston, so use an external rod lock or pilot check valve where load holding on air loss matters.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X350S Is Used
High-speed anti-rotation transfer
The through-rod keeps the payload from rotating while the variable air cushion absorbs the stop at 350 mm of travel, letting this 63 mm bore run fast transfer strokes at up to 800 mm/s without hard impacts.
Twin-load press with soft stop
With 1400.9 N available identically in both directions, rod ends can drive two light pressing or staking points at once, and the adjustable cushion gives a smooth final approach on each stroke end.
Rear-switch slide positioning
The second rod end carries a cam or flag past CMSG/DMSG/EMSG switches (magnet fitted) while the cushioned ends damp reversal, ideal for a reciprocating slide in packaging or assembly machinery.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X350S the Right Cylinder?
At 63 mm bore this is the largest MGCD, delivering 1400.9 N each way at 0.5 MPa; step down to 50 mm if you need less force, or to the 20-40 mm range for compact duties. If you want a double-rod cylinder with a fixed bumper instead of an adjustable cushion, the MGD covers bores 20-40; for a single rod with a cushion, choose the MGC. The through-rod design gives natural anti-rotation and a rear rod end you can use for a stop, flag or second load. Order the -S suffix (fitted here) when you need CMSG/DMSG/EMSG magnetic sensing, and pick FA flange or LB foot mounting plus I or Y knuckles to suit the machine. For long strokes like this 350 mm, support the rod against side loads and align the couplings carefully to protect the bearings.

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 MGCD63X350S FAQ
Because both sides of the piston see the rod-side area, the force 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), the fluid is air filtered to 40 um, temperature range is -20 to +70 C, and speed is 30-800 mm/s. The bore is 63 mm with a 20 mm rod, M18x1.5 male thread on both rod ends and 1/4" ports.
The MGCD63X350S has an adjustable air cushion at both stroke ends: you tune the orifice to decelerate the piston smoothly, which suits higher speeds and heavier loads. It is not a fixed bumper pad (that is the MGD, bores 20-40) and not a single-rod cushioned cylinder (that is the MGC). The double rod means equal force in both directions and a usable rear rod end. The fitted magnet accepts CMSG, DMSG or EMSG switches. Remember the cushion only decelerates; it does not hold the load on air loss, so add an external rod lock or pilot check valve for that.
