About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X175
The AirTAC MGCD50X175 is a double acting, double rod JIS mini cylinder with a 50 mm bore and 175 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. A variable air cushion at both ends decelerates the piston smoothly, letting this cylinder run faster or carry heavier loads than an unbuffered mini cylinder. As a rule of thumb, size the vertical load at about 0.6 of the push force, roughly 42 kg for this model.
Construction follows the JIS round-body mini format: a riveted SUS304 stainless barrel with hard-chrome plated carbon-steel rods, and a two-way lubricant-storing piston seal. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), with a proof pressure of 1.5 MPa (215 psi), a temperature range of -20 to +70 C, and speeds of 30-800 mm/s. Ports are 1/4" with PT thread. The rear rod end can carry a stop flag, a second load, or a position reference, and the through-rod resists rotation. This model ships without a magnet; order the S code to enable CMSG, DMSG or EMSG switches.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X175 Is Used
High-speed anti-rotation transfer
The through-rod keeps the load from rotating while the variable air cushion absorbs the stop at 175 mm of travel, letting the 824.3 N per side push parts between fixtures at speed.
Twin-load press with soft stop
Rod ends on both covers can each carry a pad, so one cylinder presses two points with equal 1154 N force at 0.7 MPa, and the adjustable cushion gives a smooth landing instead of a hard hit.
Rear-rod slide with position flag
Mount a stop or flag on the rear rod end to trigger a CMSG or DMSG switch (with the -S magnet option) while the main rod drives the slide, with the cushion damping each end of the 175 mm stroke.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X175 the Right Cylinder?
Choose the MGCD50X175 when you need equal force in both directions on a 175 mm stroke with smooth, adjustable deceleration at each end. At 824.3 N per side at 0.5 MPa it sits in the upper range of the MGCD family; step down to bore 32 or 40 for lighter duty, or up to bore 63 for the largest output. If you need a double-rod cylinder with a fixed bumper instead of an adjustable cushion in bores 20 to 40, look at the MGD; for a single rod with a cushion, the MGC is the equivalent. Mount with the FA flange or LB foot, and add I or Y rod knuckles on the rod ends. The -S option adds the magnet required for CMSG, DMSG or EMSG switches. For long strokes, support the rod and avoid side loads to protect the bearings.

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 MGCD50X175 FAQ
Because the rod-side area is active 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 is 1.5 MPa (215 psi), temperature range is -20 to +70 C, and speed is 30-800 mm/s on air filtered to 40 um.
The cushion is an adjustable air cushion at both stroke ends that decelerates the piston for smooth high-speed stops; it is not a lock, so use an external rod lock or pilot check valve to hold a load on air loss. The double rod gives equal force both ways and a rear rod end for a second load or flag. The MGD is a double-rod cylinder with a fixed bumper pad (bores 20 to 40 only), and the MGC is a single-rod cushioned cylinder. This model has no magnet fitted; the optional S code enables CMSG, DMSG or EMSG switches.
