About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X500S
The AirTAC MGCD50X500S is a double acting, double-rod JIS round-body mini cylinder with a 50 mm bore and a 500 mm stroke, built with a variable air cushion at both ends. Because a 20 mm hard-chrome rod exits both covers with the same M18x1.5 male thread at each end, the piston works on the rod-side area in both directions, so the output force is equal both ways: 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. Applying the usual 0.6 working-load rule of thumb, that supports a safe vertical load of roughly 50 kg at the standard 0.5 MPa supply. The adjustable cushion decelerates the piston smoothly at each stroke end, letting this cylinder run at higher speeds or carry heavier loads than an uncushioned mini cylinder without hard metal-to-metal stops.
Construction follows the JIS mini-cylinder footprint with a riveted SUS304 stainless barrel and hard-chrome-plated carbon steel rods, and the two-way lubricant-storing piston seal extends service life. The fitted magnet (the S code) allows CMSG, DMSG or EMSG switches to be mounted anywhere along the 500 mm travel for end-of-stroke or mid-stroke signalling. Air supply is filtered to 40 um, 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 range is 30-800 mm/s. Ports are 1/4" with PT threading as standard, and mounting options include FA flange and LB foot, plus I and Y rod knuckles.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X500S Is Used
High-speed anti-rotation transfer
The through-rod resists rotation while the variable air cushion brings the 500 mm slide to a smooth stop at each end, letting pallets or parts move faster than an uncushioned cylinder allows at this 824.3 N force class.
Twin-load press with soft stop
Rod ends on both sides drive two workpieces or a press and ejector in line, with equal force both ways and the adjustable cushion absorbing the impact at bottom of stroke on light forming or staking duties.
Rear-rod switch flag slide
The rear rod end carries a cam or flag past CMSG/DMSG/EMSG switches (magnet fitted on this -S model), giving position feedback along the full 500 mm stroke while the front rod does the work.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X500S the Right Cylinder?
Choose the MGCD50X500S when you need a 50 mm bore, 500 mm stroke double-rod cylinder with equal force in both directions and smooth adjustable deceleration at both stroke ends - typical for high-speed transfer slides, twin-load tooling and rear-rod switch flag setups. At 824.3 N per direction at 0.5 MPa, this is the second-largest cushioned MG-family bore; step up to the MGCD63 for about 1400.9 N, or down to the MGCD40 for 527.8 N. If you need a double-rod cylinder at bore 20-40 with a fixed bumper instead of an adjustable cushion, look at the MGD; if a single rod with a cushion suits the application, the MGC is the equivalent single-rod series. Mount with the FA flange or LB foot, add an I or Y knuckle on the rod ends, and specify the -S magnet (fitted on this model) if you need CMSG/DMSG/EMSG position switches. Note that the cushion only decelerates the piston at stroke end - it is not a lock - so use an external rod lock or pilot check valve if the load must be held on air loss, and support long 500 mm strokes against side loading.

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 MGCD50X500S FAQ
Because the double-rod design exposes the rod-side area in both directions, 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), speed range is 30-800 mm/s, temperature range is -20 to +70 C, and the air must be filtered to 40 um. Ports are 1/4" PT.
The MGCD50X500S has an adjustable air cushion at both stroke ends that decelerates the piston smoothly for high-speed or heavy-load stops - it is not a fixed bumper pad (that is the MGD double-rod build) and it is not a brake, so an external rod lock or pilot check valve is needed to hold a load on air loss. Unlike the single-rod MGC, the MGCD has a rod exiting both covers with the same M18x1.5 thread, giving equal force both ways, anti-rotation and a rear rod end for a stop flag or second load. The fitted magnet accepts CMSG, DMSG or EMSG switches.
