About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X300S
The AirTAC MGCD50X300S is a double acting, double rod JIS mini cylinder with a 50 mm bore and a 300 mm stroke. A hard-chrome rod exits both covers with the same M18x1.5 male thread at each end, so both sides of the piston see the rod-side area and 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 lets you tune the deceleration for smooth, high-speed stops under heavier loads. Because the rod is fitted with a magnet (the S code), CMSG, DMSG or EMSG switches can be clipped on for end-of-stroke sensing.
Construction follows the JIS round-body mini format: a riveted SUS304 stainless barrel with a hard-chrome (20 um) carbon-steel rod, two-way lubricant-storing piston seals and 1/4" ports. It runs 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. For a practical vertical lift, apply the usual 0.6 working-load rule to the 824.3 N push, which is about 42 kg. The rear rod end can carry a second load, a stop flag or a position reference while the front rod does the work.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X300S Is Used
Anti-rotation high-speed transfer
The through-rod resists load rotation while the variable air cushion absorbs the stop at each end, letting a 50 mm bore move fixtures at speed on a 300 mm stroke without hard metal-to-metal impact.
Twin-load press with soft stop
Rod ends front and rear, each M18x1.5, can drive two pads in line, and the adjustable cushion gives a controlled deceleration before bottom-out for light forming or marking at up to 824.3 N per direction.
Sensed rear-flag slide
With the magnet fitted, CMSG or DMSG switches on the barrel plus a flag on the rear rod end give position confirmation for a conveyor pusher or gate, while the front rod carries the tooling.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X300S the Right Cylinder?
Size MGCD bores by the equal both-way force: the 50 mm bore delivers 824.3 N at 0.5 MPa each way, between the 40 mm (527.8 N) and 63 mm (1400.9 N) models. If you need a cushioned single-rod cylinder instead of a through-rod, choose the MGC; for a bumper-type double rod in bores 20-40 without adjustable cushioning, the MGD is the alternative. This MGCD50X300S suits anti-rotation transfer and twin-load work where smooth, adjustable deceleration matters. Mount with the LB foot or FA flange and add I or Y rod knuckles for the joint (SDB and CB are not offered). The S code means the magnet is already fitted for CMSG/DMSG/EMSG switches. At 300 mm stroke, keep side loads low or guide the load externally, and remember the air cushion only decelerates the stroke ends - it is not a lock, so add a pilot check valve or external rod lock if the load must be held on air loss.

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 MGCD50X300S FAQ
Because it is a double rod cylinder, force is equal both ways: 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. 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, and the maximum standard stroke for this 50 mm bore is 500 mm, so 300 mm is a standard stroke.
Both ends carry a variable air cushion you adjust with a needle screw to soften piston deceleration - it is not a fixed bumper pad and not a brake, so it will not hold the load on air loss. The rod exits both covers with the same M18x1.5 thread, giving equal force and natural anti-rotation, unlike the single-rod cushioned MGC or the bumper-type double-rod MGD. The S in MGCD50X300S means the piston magnet is fitted, so CMSG, DMSG or EMSG switches can be mounted on the barrel.
