About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X350S
The AirTAC MGCD50X350S is a double acting, double rod JIS round-body mini cylinder with a 50 mm bore and a 350 mm stroke. A rod exits both covers with the same M18x1.5 male thread at each end, so both strokes 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. Because the piston moves symmetrically, the two rod ends travel together, giving natural anti-rotation behavior and a rear rod end you can use for a position flag, a stop cam, or a second light load. A variable air cushion at both ends is adjustable so you can tune the deceleration for high-speed cycles or heavier moving masses, instead of relying on a fixed bumper pad.
Practical sizing: at a realistic working load of roughly 0.6 times the 0.5 MPa force, this cylinder handles about 494 N, which corresponds to a safe vertical lift of roughly 50 kg. The barrel is SUS304 stainless with a hard-chrome plated 20 mm rod, and the riveted round-body construction follows the JIS mini-cylinder footprint. Air supply should be filtered to 40 um, with an operating range of 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, and speed 30-800 mm/s. The fitted magnet (the S code) allows CMSG, DMSG, or EMSG switches, ports are 1/4", and mounting is FA flange or LB foot with I and Y rod knuckles available.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X350S Is Used
High-speed anti-rotation transfer
The through-rod keeps the moving fixture symmetric while the adjustable air cushion absorbs the stop at 350 mm of travel, letting the slide run near the top of the 30-800 mm/s range without hard impact.
Twin-load press with soft stop
With about 824.3 N available each way at 0.5 MPa, both rod ends can carry light pressing or riveting tools, and the variable cushion gives a controlled landing instead of a metal-to-metal bump.
Rear-switch positioning slide
The rear rod end drives a cam or flag past CMSG/DMSG/EMSG switches (magnet fitted), giving end-of-stroke confirmation on a long 350 mm stroke without extra brackets on the front tooling.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X350S the Right Cylinder?
Choose the MGCD50X350S when you need a 350 mm stroke with equal force in both directions and smooth, adjustable end-of-stroke deceleration: the double rod plus variable air cushion suits high-speed slides and twin-sided tooling. At 824.3 N per direction at 0.5 MPa, bore 50 sits in the upper-middle of the MGCD range (20 to 63 mm); step up to bore 63 (1400.9 N) for heavier loads or down to bore 40 (527.8 N) to save space. If you need a double-rod cylinder at bore 20-40 without cushioning, the MGD with fixed bumpers is the lighter option; for a single rod with cushion, use the MGC. Note the cushion only decelerates the stroke ends: it is not a lock, and the load is not held on air loss, so add an external rod lock or pilot check valve for holding. Mount with FA flange or LB foot, add I or Y knuckles for swiveling joints, and the fitted magnet supports CMSG/DMSG/EMSG switches. For long 350 mm strokes, keep side loads off the rod and use proper guiding.

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 MGCD50X350S FAQ
Output is equal in both directions because both sides of the piston are rod-side area: 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 air must be filtered to 40 um. Ports are 1/4" and the maximum standard stroke for bore 50 is 500 mm, so 350 mm is a standard stroke.
The cushion at each end is an adjustable air chamber that decelerates the piston just before the cover, so you can tune the stop for speed and load; it is not a lock and does not hold the load on air loss, so use an external rod lock or pilot check valve for holding. Unlike the MGD, which is a double-rod cylinder with fixed bumper pads, the MGCD has an adjustable air cushion; unlike the MGC, which is single rod, the MGCD has a rod at both ends with the same M18x1.5 thread, giving equal force both ways and a rear rod end for switches or a second load. The fitted magnet accepts CMSG, DMSG, or EMSG switches.
