About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X100
The AirTAC MGCD63X100 is a double acting, double-rod JIS round-body mini cylinder with a 63 mm bore and 100 mm stroke, fitted with a variable air cushion at both ends. A 20 mm rod exits each cover with the same M18x1.5 male thread, so both ends of the piston see the rod-side area and 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. The adjustable cushion decelerates the piston smoothly at each end of travel, making this the largest cushioned MG-family bore for high-speed or heavier-duty stops. The through-rod also gives natural anti-rotation and a rear rod end you can use for a stop flag or a second load.
Construction follows the JIS mini-cylinder footprint with a riveted SUS304 stainless barrel and hard-chrome plated carbon-steel rods for corrosion resistance and long seal life. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), withstands 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 1/4". As a practical sizing rule, plan on roughly 85 kg of safe vertical load at 0.5 MPa, since a realistic working load is about 0.6 of the available force.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X100 Is Used
High-speed anti-rotation transfer
The through-rod keeps the load from rotating while the variable air cushion brings 1400.9 N of equal bidirectional force to a smooth stop at 100 mm of travel, ideal for fast pick-and-place slides.
Twin-load press with soft stop
Rod ends on both covers let you tool up two workpoints at once, and the adjustable cushion at each end absorbs the impact when pressing or staking lighter assemblies at this force class.
Rear-switch reciprocating slide
Use the rear rod end to drive a flag past CMSG, DMSG or EMSG switches (with the S magnet option) for end-of-stroke confirmation on a reciprocating conveyor or gate pusher.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X100 the Right Cylinder?
At 63 mm bore this is the largest MGCD in the range, delivering 1400.9 N each way at 0.5 MPa, so size down to 50 mm or 40 mm if your load is lighter. If you need a double-rod cylinder without cushioning in the smaller 20-40 mm bores, look at the MGD (fixed bumper); for a single-rod cushioned cylinder, the MGC is the equivalent. The variable air cushion at both ends suits high-speed cycles and heavier moving masses, and the through-rod provides anti-rotation plus a rear rod end for a stop flag or second load. Mounting options are LB foot and FA flange, with I and Y rod knuckles available (no CB or SDB). Add the S option to the model code to fit a magnet for CMSG, DMSG or EMSG switches; without it no sensor can be mounted. Standard strokes run to 500 mm for this bore; for long strokes, guide the load externally to protect the rod from 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 MGCD63X100 FAQ
Because it is a double-rod cylinder, force 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. 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 at speeds of 30-800 mm/s, and has 1/4" ports with M18x1.5 rod threads on both ends.
The MGCD has a variable air cushion at both ends: you adjust the bleed to decelerate the piston smoothly into each end cover, which suits higher speeds and heavier loads. The MGD is also a double-rod cylinder but uses fixed bumper pads instead of an adjustable cushion, while the MGC is a single-rod cushioned cylinder with a larger push force than pull force. Note that the cushion only decelerates the stroke end; it is not a lock, so use an external rod lock or pilot check valve if the load must be held on air loss. Add the S option to fit CMSG, DMSG or EMSG position sensors.
