About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X50
The AirTAC MGCD50X50 is a double acting, double-rod JIS mini cylinder with a 50 mm bore and 50 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 deliver an equal force of about 824.3 N each way at 0.5 MPa (1154 N at 0.7 MPa, up to a theoretical 168.1 kgf at 1.0 MPa). A variable air cushion at both ends lets you tune deceleration for smooth, high-speed stops, and the rear rod end can carry a second load, a stop plate or a position flag while the through-rod design naturally resists rotation.
Built to the JIS footprint, the MGCD50X50 uses a riveted round body in SUS304 stainless with a hard-chrome plated 20 mm rod for long service in harsh environments. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), withstands a proof pressure of 1.5 MPa (215 psi), operates from -20 to +70 C at 30-800 mm/s, and connects through 1/4" ports. For a realistic working load, size around 0.6 of the push force, which is roughly 494 N, or about 42 kgf halved to a safe vertical figure near 21 kg.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X50 Is Used
High-speed anti-rotation transfer
The through-rod keeps the load from twisting while the variable air cushion absorbs the stop, letting the MGCD50X50 shuttle fixtures between stations at speed without hard impact.
Twin-load press with soft stop
With 824.3 N available identically in each direction, the front rod can press a part while the rear rod carries an ejector or counter-feature, and both cushions give a gentle landing.
Rear-switch slide
The second rod end mounts a flag or stop plate for CMSG/DMSG/EMSG switches (with the -S magnet option), turning the 50 mm stroke into a compact cushioned indexing slide.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X50 the Right Cylinder?
Choose the MGCD50X50 when you need equal force in both directions with smooth, adjustable end-of-stroke deceleration: its variable air cushion at both ends suits higher speeds and heavier loads than an unbuffered cylinder. At 50 mm bore it delivers 824.3 N per direction at 0.5 MPa; step down to bore 32 or 40 for lighter duty, or up to 63 for the largest force in this family. If you need a double-rod cylinder at bore 20-40 without cushioning, the MGD with fixed bumpers is the alternative; for a single rod with cushion, pick the MGC. Mount with the FA flange or LB foot, add I or Y rod knuckles on the loaded end, and order the -S option if you want CMSG, DMSG or EMSG switch sensing - without the S code no sensor can be fitted. For strokes beyond the 500 mm standard maximum or applications with significant side load, guide the load externally.

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 MGCD50X50 FAQ
It is a double acting, double-rod JIS mini cylinder, bore 50 mm, stroke 50 mm, rod 20 mm with M18x1.5 male thread on both ends and 1/4" ports. 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 range -20 to +70 C, speed 30-800 mm/s, on air filtered to 40 um.
The MGCD50X50 has an adjustable air cushion at both ends that decelerates the piston near each stroke end, so you can run higher speeds or carry heavier loads without metal-to-metal impact. It is not a fixed bumper pad (that is the MGD, a double-rod cylinder without cushioning offered in bores 20-40) and not the MGC, which is a single-rod cushioned cylinder. Because a rod exits both covers, the MGCD delivers equal force in both directions, and the rear rod end can carry a second load or a sensor flag. Note the cushion only decelerates the stroke end - it does not lock the piston, so use an external rod lock or pilot check valve if the load must be held on air loss. Order the -S option to enable CMSG, DMSG or EMSG position sensing.
