About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X175S
The AirTAC MGCD50X175S is a double acting, double rod JIS mini cylinder with a 50 mm bore and 175 mm stroke. A hard-chrome steel rod exits BOTH covers with the same M18x1.5 male thread at each end, so the piston sees the rod-side area in either direction and delivers an EQUAL 824.3 N at 0.5 MPa (1154 N at 0.7 MPa) both ways. A variable air cushion at each end is adjusted with a needle to decelerate the piston smoothly, letting you run higher speeds or heavier loads without hard metal-to-cover stops. The through-rod also resists rotation and gives you a free rear rod end for a stop flag, switch trip, or a second load.
Construction follows the JIS round-body mini format: a riveted SUS304 stainless barrel with hard-chrome (20 um) plated rods and two-way lubricant-storing piston seals. 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. Ports are 1/4". The fitted magnet (S code) accepts CMSG, DMSG, or EMSG switches. As a buyer insight: at a realistic 0.6 duty factor the 824.3 N working force supports roughly a 42 kg vertical figure, so size tooling and guides accordingly. Mount with FA flange or LB foot, add I or Y rod knuckles, and order PT (blank), G, or NPT ports.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X175S Is Used
High-speed anti-rotation transfer
The 824.3 N equal push and pull moves pallets or fixtures between stations at speed, while the variable air cushion softens each end stop and the through-rod keeps the load from twisting.
Twin-load press with soft stop
Rod ends front and rear each carry a tool or pad, doubling usable contact points with 824.3 N per direction, and the adjustable cushion gives a smooth, non-slam final approach on light forming or marking work.
Rear-switch slide with position feedback
The rear rod end trips a flag or the fitted magnet signals CMSG/DMSG/EMSG switches, giving a 175 mm stroke slide with cushioned ends and end-position confirmation on a 50 mm bore actuator.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X175S the Right Cylinder?
Choose the MGCD50X175S when you need a cushioned, equal-force double-rod cylinder in the 824 N class with a 175 mm stroke. If 824.3 N at 0.5 MPa is marginal, step up to bore 63 (1400.9 N); if it is generous, bore 40 (527.8 N) saves space. For a bumper-pad double-rod cylinder without adjustable cushioning in bores 20-40, look at the MGD; for a single rod with variable cushion, the MGC is the counterpart. The variable air cushion suits high-speed or high-inertia stops; the through-rod gives anti-rotation and a rear rod end. Mounting: FA flange or LB foot, with I or Y knuckles on the rod ends (no SDB or CB options on this family). The -S magnet enables CMSG/DMSG/EMSG position sensing. For strokes beyond the 500 mm maximum standard stroke of this bore, or with significant side loads, plan external guides and support.

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 MGCD50X175S FAQ
Because the double-rod design exposes the rod-side area in both directions, output is equal each way: 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), fluid is air filtered to 40 um, temperature range -20 to +70 C, and speed 30-800 mm/s.
Each cover has an adjustable air cushion: a needle valve throttles the exhaust at stroke end to decelerate the piston smoothly, so you can tune the braking for higher speeds or heavier loads. Unlike the MGD, which uses fixed bumper pads, the MGCD cushion is adjustable, and unlike the single-rod MGC, the MGCD has a rod at both ends so force is equal both ways. The cushion only decelerates; it does not lock the piston, so use an external rod lock or pilot check valve if the load must hold on air loss. The fitted magnet (S) accepts CMSG, DMSG, or EMSG switches.
