About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X175S
The AirTAC MGCD40X175S is a double acting, double-rod JIS round-body mini cylinder with a 40 mm bore and 175 mm stroke. A rod exits both covers with the same M14x1.5 male thread each end, so both sides of the piston see the rod-side area and the output force is equal in both directions: about 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa, with a theoretical maximum of 107.6 kgf at 1.0 MPa. A variable air cushion at both ends lets you tune the deceleration for smooth stops at higher speeds or with heavier loads, and the rear rod end doubles as a mounting point for a stop, flag or second load. As a rule of thumb, plan on roughly 27 kg as a safe vertical load at 0.5 MPa.
Construction follows the JIS mini-cylinder footprint: a riveted SUS304 stainless barrel with a hard-chrome-plated 16 mm rod for corrosion resistance and long seal life, running 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. Air ports are 1/8". This S-coded model ships with a magnet fitted, so CMSG, DMSG or EMSG switches can be clipped on for end-of-stroke sensing. Mounting options are FA flange or LB foot, with I and Y rod knuckles available.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X175S Is Used
High-speed anti-rotation transfer
The through-rod resists rotation while the variable air cushions tame 175 mm strokes at speed, moving pallets or fixtures sideways with equal 527.8 N push and pull at 0.5 MPa.
Twin-load press with soft stop
Drive a small press or clinch station from the front rod while the rear rod carries a stop or second tool; adjustable cushions give a smooth, impact-free end of stroke on both sides.
Magnet-sensed slide with rear flag
The fitted magnet feeds CMSG/DMSG/EMSG switches for stroke-end signals, while the rear rod end drives a position flag or counter on a 40 mm-class conveyor reject or indexing slide.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X175S the Right Cylinder?
Choose the MGCD40X175S when you need a cushioned double-rod cylinder in the 40 mm class: equal force in both directions, anti-rotation through-rod geometry, and adjustable air cushions at both ends for fast, smooth stops. If 527.8 N each way at 0.5 MPa is more than your load needs, step down to the MGCD32; if you need more, step up to the MGCD50 or MGCD63, the largest bores in the MG family. For a bumper-pad double-rod cylinder at 20-40 mm bores, look at the MGD instead; for a single rod with a cushion, the MGC. The fitted magnet means any CMSG/DMSG/EMSG switch works out of the box. Use FA flange or LB foot mounting plus I/Y knuckles for linkage. For long strokes with side load, add external guidance, and remember the cushion only decelerates the stroke end: it is not a lock, so fit an external rod lock or pilot check valve if the load must be held on air loss.

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 MGCD40X175S FAQ
Because it is a double-rod cylinder, force is equal both ways: 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa, with a theoretical maximum of 107.6 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. Ports are 1/8" and the rod thread is M14x1.5 on both ends.
The variable air cushion at each end is adjusted with a needle valve to decelerate the piston smoothly, unlike the fixed bumper pad used on the MGD. A rod exits both covers, so force is identical in both directions and the rear rod end can carry a stop, flag or second load. This S model includes the magnet, so CMSG, DMSG or EMSG switches mount directly for position sensing. Note the cushion is not a brake: use an external rod lock or pilot check valve to hold a load on air loss.
