About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X75
The AirTAC MGCD50X75 is a JIS-standard round-body mini cylinder, double acting and double rod, with a variable air cushion at both ends. A 20 mm rod exits both covers with the same M18x1.5 male thread, so the two rod ends move together and the piston sees the rod-side area in either direction. That gives an equal output of about 824.3 N each way at 0.5 MPa (1154 N at 0.7 MPa), and the adjustable cushion decelerates the piston smoothly into each end cover, letting you run faster strokes or carry heavier loads without hard metal-to-metal stops. With a usable rule of thumb of roughly 0.6 of the push force, a realistic working load is about 50 kg horizontally, or around 42 kg as a safe vertical figure.
Construction follows the JIS mini-cylinder footprint: a SUS304 stainless barrel with a hard-chrome plated carbon-steel rod, riveted and rolled covers, and a two-way lubricant-storing piston seal. Ports are 1/4", operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, temperature range is -20 to +70 C, and speed range is 30-800 mm/s. The rear rod end doubles as a mounting point for a stop, flag or second load, and adding the optional S magnet code enables CMSG, DMSG or EMSG position sensing. Mount with the FA flange or LB foot, and pair with I or Y rod knuckles.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X75 Is Used
High-speed anti-rotation transfer
Moves parts between stations at speed with the variable air cushion absorbing the stop at each end, while the twin 20 mm rods keep the load from rotating without extra guides.
Twin-load press with soft stop
The through-rod carries a tool on each end for a 75 mm press or clinch cycle, applying about 824.3 N per side at 0.5 MPa, with the adjustable cushion easing the final approach.
Rear-switch slide
The rear rod end drives a flag or stop block while the front rod does the work, and the optional S magnet with a CMSG or DMSG switch reports position on both ends of the stroke.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X75 the Right Cylinder?
Size the MGCD by force, not bore alone: this 50 mm bore delivers 824.3 N in both directions at 0.5 MPa, sitting between the 40 mm (527.8 N) and 63 mm (1400.9 N) models, so step up to MGCD63X75 if your load needs more margin. Choose the MGCD when you want a variable air cushion plus a through-rod; if you need a bumper-pad double-rod cylinder in the 20-40 mm range, the MGD is that variant, and for a single rod with cushion the MGC is the equivalent. The adjustable cushion at both ends suits high-speed or high-inertia stops, and the twin rods give natural anti-rotation plus a rear rod end for a stop, flag or second load. Mounting is FA flange or LB foot with I and Y knuckles available (no SDB or CB); add the S magnet code if you need CMSG/DMSG/EMSG sensing. For strokes beyond the 500 mm standard maximum or heavy side loads, add external guidance.

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 MGCD50X75 FAQ
Because it is a double rod cylinder, output 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 is 1.5 MPa (215 psi), temperature range is -20 to +70 C, and speed is 30-800 mm/s on filtered air (40 um). Ports are 1/4" and the rod thread is M18x1.5 on both ends.
The cushion is an adjustable air cushion at both ends that decelerates the piston near each end cover, so you can tune the stop for higher speeds or heavier loads. It only slows the piston at stroke ends; it is not a lock, so the cylinder will not hold its load on air loss and an external rod lock or pilot check valve is recommended. Unlike the MGD, which uses fixed bumper pads, the MGCD has this adjustable cushion; unlike the single-rod MGC, the MGCD has a rod at both ends, so force is identical in both directions. Add the S magnet code to fit CMSG, DMSG or EMSG switches.
