About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X500
The AirTAC MGCD40X500 is a double acting, double-rod JIS round-body mini cylinder with a 40 mm bore and a 500 mm stroke, the maximum standard stroke for this bore. Because a 16 mm rod exits both covers with an M14x1.5 male thread at each end, the piston sees the rod-side area in either direction, so the output force is equal both ways: about 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa, with a theoretical maximum of 107.6 kgf at 1.0 MPa. A variable air cushion at both ends lets you dial in smooth deceleration for high-speed or heavier-load stops, and the rear rod end doubles as an anti-rotation guide, a stop flag, or a second load path.
Construction follows the JIS mini-cylinder footprint: a riveted SUS304 stainless barrel with hard-chrome-plated carbon steel rods, running on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof tested to 1.5 MPa (215 psi), from -20 to +70 C at 30-800 mm/s. Ports are 1/8". For a realistic working load, size around 0.6 of the push force, roughly 316 N, which supports a safe vertical load of about 16 kg. Mounting is FA flange or LB foot with I and Y rod knuckles; add the optional S magnet code to enable CMSG, DMSG or EMSG switches.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X500 Is Used
High-speed anti-rotation transfer
The through-rod keeps the payload from twisting while the variable air cushion brings each 500 mm traverse to a smooth stop at 30-800 mm/s, with 527.8 N available in either direction.
Twin-load press with soft stop
Rod ends front and rear let one MGCD40X500 carry two workpieces, and the adjustable air cushion at both ends cushions the press stroke instead of slamming metal on metal.
Long-stroke slide with rear switching
Use the rear rod end as a flag or stop on a 500 mm slide; add the S magnet option to fit CMSG or DMSG switches for end-of-stroke detection.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X500 the Right Cylinder?
Choose the MGCD40X500 when you need equal force in both directions over a long 500 mm stroke with controlled, cushioned stops: the through-rod resists rotation and the adjustable air cushion at each end tames high-speed deceleration. If 527.8 N per direction at 0.5 MPa is marginal, step up to MGCD50 for 824.3 N; if it is generous, MGCD32 gives 345.6 N. For a bumper-ended double-rod cylinder in this bore range, look at the MGD instead; for a single rod with a cushion, the MGC. Specify LB foot or FA flange mounting plus I or Y knuckles as needed, and order the S suffix if you plan to fit CMSG/DMSG/EMSG position sensors. At 500 mm stroke, keep side loads low and use guides or the rear rod end 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 MGCD40X500 FAQ
It is double acting with a double rod, so force is equal both ways: 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa, with a theoretical maximum of 107.6 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-800 mm/s, on air filtered to 40 um. Ports are 1/8" and the rod thread is M14x1.5 at both ends.
The MGCD40X500 has a variable air cushion at both ends: an adjustable air dam that decelerates the piston near each stroke end for smooth high-speed stops. It is not a lock, so the load is not held on air loss; use an external rod lock or pilot check valve for holding. Unlike the MGD, which uses fixed bumper pads, the MGCD cushion is adjustable, and unlike the single-rod MGC it has a rod at both ends, giving equal force in both directions. Order the S suffix to enable CMSG, DMSG or EMSG sensors.
