About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X450S
The AirTAC MGCD50X450S is a double acting, double-rod JIS mini cylinder with a 50 mm bore and a 450 mm stroke. Because a 20 mm rod exits both covers with the same M18x1.5 male thread at each end, both sides of the piston see the rod-side area, so the output force is equal in both directions: about 824.3 N at 0.5 MPa and 1154 N at 0.7 MPa, with a theoretical maximum of 168.1 kgf at 1.0 MPa. A variable air cushion at both ends decelerates the piston smoothly, letting this long 450 mm stroke run at higher speeds with heavier loads without hard metal-to-metal stops. The rear rod end can carry a second load, a stop plate, or a position flag, and the through-rod resists rotation.
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 for long service 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. The fitted magnet (S code) allows CMSG, DMSG or EMSG switches to be mounted along the barrel. As a practical sizing rule, apply about 0.6 of the push force, so plan on roughly 42 kg for a safe vertical load on this cylinder.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X450S Is Used
High-speed anti-rotation transfer
The 450 mm stroke moves parts between stations at up to 800 mm/s, with the variable air cushion braking the load smoothly at each end while the through-rod keeps the carriage from rotating.
Twin-load press with soft stop
Rod ends on both sides each deliver about 824.3 N at 0.5 MPa, so one cylinder can press or clamp two opposing points, with the adjustable cushion giving a gentle landing at full compression.
Rear-switch long slide
The rear rod end carries a position flag for the fitted magnet switches, giving end-of-travel signals on a long 450 mm slide without extra hardware.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X450S the Right Cylinder?
Choose the MGCD50X450S when you need a 450 mm stroke with equal force in both directions and cushioned stops at both ends. At 824.3 N per direction at 0.5 MPa, the 50 mm bore suits medium-duty transfer, push-pull and twin-load tasks; step up to the 63 mm bore (1400.9 N) for heavier loads or down to the 40 mm bore (527.8 N) if space or force demand is lower. The 450 mm stroke is within the 500 mm maximum standard stroke for this bore, so no custom build is needed. If you need a double-rod cylinder with fixed bumper pads instead of an adjustable cushion at bores 20-40, look at the MGD; for a single-rod cushioned cylinder, the MGC is the equivalent. Mount with the FA flange or LB foot, add I or Y rod knuckles on the rod ends, and remember the air 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. This unit ships with the magnet fitted, ready for CMSG, DMSG or EMSG switches.

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 MGCD50X450S FAQ
It delivers 824.3 N in each direction at 0.5 MPa and 1154 N at 0.7 MPa, with a theoretical maximum of 168.1 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), temperature range is -20 to +70 C, speed is 30-800 mm/s, and the fluid is air filtered to 40 um. Ports are 1/4" and the rod thread is M18x1.5 at both ends.
The variable air cushion at both ends is adjustable, so you can tune the deceleration to the load and speed for smooth stops; it only brakes the piston near stroke end and does not lock or hold the load on air loss. Because a rod exits both covers, force is equal both ways and the rear rod end is free for a stop, flag or second load. The MGD is a double-rod cylinder with fixed bumper pads instead of an adjustable cushion, and the MGC is a single-rod cushioned cylinder. The fitted magnet on this S-coded model accepts CMSG, DMSG or EMSG switches.
