About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X350
The AirTAC MGCD63X350 is a double acting, double-rod JIS round-body mini cylinder with a 63 mm bore and 350 mm stroke. A rod exits both covers with the same M18x1.5 male thread at each end, so the piston works on the rod-side area in both directions and delivers an equal force of about 1400.9 N each way at 0.5 MPa (1961.2 N at 0.7 MPa, up to a theoretical 285.7 kgf at 1.0 MPa). A variable air cushion at both ends lets you tune the deceleration for smooth, high-speed stops under heavier loads, while the through-rod resists rotation and gives you a rear rod end for a stop flag or a second load. This is the largest bore in the cushioned MGCD range, sized for demanding transfer and press duties.
Construction follows the JIS mini-cylinder footprint with a riveted SUS304 stainless barrel and hard-chrome plated 20 mm rods for corrosion resistance and long seal life. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a proof pressure of 1.5 MPa (215 psi), air filtered to 40 um, a temperature range of -20 to +70 C, and speeds of 30-800 mm/s. Ports are 1/4". Mounting is via FA flange or LB foot, with I and Y rod knuckles available. As a rule of thumb, keep the working load to about 0.6 of the push force, so plan on roughly 85 kg for a vertical lift on this model. The optional S code adds a magnet for CMSG, DMSG or EMSG switches; this SKU has no magnet, so no sensor can be mounted.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X350 Is Used
High-speed anti-rotation transfer
The through rod keeps the load from twisting while the variable air cushion at each end absorbs the energy of fast 30-800 mm/s travel, letting this 1400.9 N cylinder index heavy pallets or fixtures without hard stops.
Twin-load press with soft stop
Rod ends front and rear, each with an M18x1.5 thread, can carry two tools or a tool and an anvil, and the adjustable cushion delivers a controlled 1961.2 N at 0.7 MPa into the workpiece instead of a jarring impact.
Rear-switch slide
Use the rear rod end to drive a cam or flag past a CMSG or DMSG switch (order the S variant for the magnet) while the main end moves the load, with the cushion smoothing the reversal at each end of the 350 mm stroke.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X350 the Right Cylinder?
Size the MGCD63X350 when your load needs more than the 824 N each-way force of the bore 50 model; this 63 mm bore gives 1400.9 N both ways at 0.5 MPa, the largest output in the MGCD family. If you need a double-rod cylinder at bore 20 to 40 without cushioning, look at the MGD with its fixed bumper; for a single-rod cushioned cylinder, the MGC is the right pick. Choose the MGCD when you want adjustable deceleration at both stroke ends for high-speed or heavy-load stops, plus the anti-rotation and twin-end benefits of a through rod. Mount with the FA flange or LB foot and add I or Y knuckles on the rod ends. Order the S variant if you need position detection with CMSG, DMSG or EMSG switches. The 350 mm stroke is within the 500 mm maximum standard stroke for this bore; for very long strokes, watch side loading on the rods and guide the load externally.

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 MGCD63X350 FAQ
Because it is a double-rod cylinder, both strokes act on the rod-side area, so output is equal in both directions: 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 MGCD63X350 has an adjustable air cushion at both ends that decelerates the piston near each stroke end, so you can run higher speeds or carry heavier loads without damaging stops; it is a deceleration feature, not a lock, so use an external rod lock or pilot check valve if the load must be held on air loss. Unlike the MGD, which is a double-rod cylinder with a fixed bumper pad, the MGCD cushion is adjustable. Unlike the single-rod MGC, the MGCD's through rod gives equal force both ways, anti-rotation, and a second rod end. The optional S code adds a magnet for CMSG, DMSG or EMSG switches.
