About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X150S
The AirTAC MGCD40X150S is a double acting, double-rod JIS round-body mini cylinder with a 40 mm bore and 150 mm stroke. Because a 16 mm hard-chrome rod exits both covers, the piston sees the rod-side area in each direction, so the output force is equal both ways: 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 each end decelerates the piston smoothly, letting this cylinder run at higher speeds and carry heavier loads than an unbuffered mini cylinder without metal-to-metal stop shock.
The riveted round body is built from SUS304 stainless steel with hard-chrome-plated rods, and the two-way lubricant-storing piston seal extends service life. This S-coded model carries a magnet, so CMSG, DMSG or EMSG switches can be clipped onto the barrel for end-of-stroke signalling. Air supply is filtered to 40 um, operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C and speed 30-800 mm/s. As a practical rule of thumb, size the load at about 0.6 of the push force: roughly 32 kg horizontal, or about 16 kg for a vertical lift.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X150S Is Used
High-speed anti-rotation transfer
The through-rod resists rotation while the variable air cushion absorbs the stop, so the MGCD40X150S can shuttle fixtures between stations at speed with its 527.8 N per-direction thrust and no end-of-stroke bang.
Twin-load press with soft stop
Rod ends on both covers let one cylinder carry a forming tool on the front rod and a clamp or ejector on the rear rod, each cushioned to a smooth stop within the 107.6 kgf theoretical force class.
Rear-switch slide
With the fitted magnet and a CMSG or DMSG switch on the rear rod end, this slide gives position feedback for indexing fixtures while the adjustable cushions tame the 30-800 mm/s travel at both ends.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X150S the Right Cylinder?
Choose the MGCD40X150S when you need equal force in both directions, anti-rotation guidance and smooth cushioned stops in one 40 mm bore package: the through-rod gives you a rear rod end for a stop flag, switch cam or second load. If your force budget is lower, step down to MGCD32 (about 345.6 N each way at 0.5 MPa); for heavier duty, MGCD50 delivers about 824.3 N. For a bumper-cushioned double-rod cylinder in this bore range, look at the MGD; for a single rod with cushion, the MGC. Mount with the FA flange or LB foot, add I or Y rod knuckles for off-axis links, and note the -S magnet is already fitted for CMSG/DMSG/EMSG sensing. Keep side loads off the rod on strokes near the 500 mm maximum, and remember the cushion only decelerates the stroke end: it is not a lock, so use an external rod lock or pilot check valve if the load must hold 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 MGCD40X150S FAQ
As a double-rod cylinder the force is equal both directions: 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), temperature -20 to +70 C, speed 30-800 mm/s, and the air must be filtered to 40 um. Ports are 1/8" and the rod thread is M14x1.5 on both ends.
The MGCD40X150S has a variable air cushion at both ends: an adjustable air dam that decelerates the piston near each stroke end, so it is ideal for high speeds and heavier loads. It is not a fixed bumper pad (that is the MGD) and not a single-rod design (that is the MGC). The cushion only slows the piston; it does not lock or hold the load on air loss, so add an external rod lock or pilot check valve where holding is required. The fitted S magnet enables CMSG, DMSG or EMSG position switches.
