About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X450
The AirTAC MGCD40X450 is a double acting, double-rod JIS round-body mini cylinder with a 40 mm bore and a 450 mm stroke. A 16 mm hard-chrome-plated rod exits BOTH covers with the same M14x1.5 male thread each end, so both rod ends move together and the piston sees the rod-side area in either direction. That makes the output force 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 both ends is adjusted with a needle to decelerate the piston smoothly, so this long 450 mm stroke can run fast without hard metal-to-metal stops, and the through-rod resists rotation while the rear rod end can carry a stop flag, position sensor trip, or a second light load.
Construction follows the JIS mini-cylinder footprint: a riveted round body in SUS304 stainless steel with hard-chrome rods, and a two-way lubricant-storing piston seal. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, a temperature range of -20 to +70 C, and speeds of 30-800 mm/s. Ports are 1/8". For a realistic working load, size around 0.6 of the force, roughly 316 N or about 32 kg; for a vertical lift, halve the 0.5 MPa figure to about 26 kg. Mounting is FA flange or LB foot, with I and Y rod knuckles available; no CB or SDB options. The cylinder ships without a magnet, so no position sensor can be fitted; order the S code to enable CMSG, DMSG or EMSG switches.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X450 Is Used
High-speed anti-rotation transfer
The 450 mm stroke moves parts between stations at up to 800 mm/s while the through-rod keeps the carrier from twisting; the variable air cushion at each end absorbs the momentum so a 30 kg-class load stops smoothly instead of slamming.
Twin-load press with soft stop
Both M14x1.5 rod ends carry tools, so two light pressing or riveting points work in unison with an equal 527.8 N each way at 0.5 MPa, and the adjustable cushion gives a gentle landing on delicate assemblies.
Rear-switch long slide
The rear rod end drives a flag or cam for end-of-stroke confirmation on a 450 mm conveyor pusher or gate, keeping the main rod free for the load; add the S code magnet to fit CMSG, DMSG or EMSG switches.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X450 the Right Cylinder?
Size by force, not bore: the MGCD40X450 delivers an equal 527.8 N each way at 0.5 MPa, so check your load against that figure in BOTH directions and step up to MGCD50 or MGCD63 if you need more, or down to MGCD32 if 345.6 N suffices. Choose this model when you want a cushioned, anti-rotation through-rod on a long 450 mm stroke; if you need a bumper-ended double-rod cylinder at this bore, that is the MGD, and for a single rod with cushion it is the MGC. The variable air cushion only decelerates the piston at each stroke end - it is not a lock, and the cylinder will not hold its load on air loss, so add an external rod lock or pilot check valve for safe load holding. Mount with the FA flange or LB foot and pair with an I or Y knuckle for off-axis links. The 450 mm stroke is within the 500 mm maximum standard stroke for this bore, but long strokes are more sensitive to side load, so keep the rod aligned or use guides. If you need position detection, order the S variant to enable CMSG, DMSG or EMSG switches; this no-S model accepts no sensor.

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 MGCD40X450 FAQ
Because it is a double-rod cylinder, the force is equal in 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 is 1.5 MPa (215 psi), the fluid is air filtered to 40 um, temperature range is -20 to +70 C, and speed is 30-800 mm/s. Ports are 1/8" and the rod thread is M14x1.5 at both ends.
The MGCD40X450 has an adjustable air cushion at both ends: a needle valve meters the exhaust at each stroke end to decelerate the piston smoothly, which suits fast, long strokes like this 450 mm version. It is not a fixed bumper pad (that is the MGD double-rod build) and it is not a lock - the cylinder will not hold a load on air loss, so use an external rod lock or pilot check valve for holding. The MGC is the single-rod cushioned variant. This unit ships without a magnet, so no sensor can be mounted; the S code enables CMSG, DMSG or EMSG switches.
