Airtac MG Stainless Steel Mini Air Cylinder MG40X200S
The AirTAC Airtac MG Stainless Steel Mini Air Cylinder MG40X200S is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 200mm stroke, 1/8" air ports and a SUS304 stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.

About the Airtac MG Stainless Steel Mini Air Cylinder MG40X200S
With a 40 mm bore and 200 mm stroke, this MG delivers 628.3 N of push and 527.8 N of pull at 0.5 MPa, rising to 879.6 N at 0.7 MPa - the strongest bore in the JIS-standard MG range. It is a double acting round-body mini cylinder: air drives the rod out and back, and a fixed anti-impact bumper pad at each stroke end softens the direction change without adding an adjustable cushion. The SUS304 stainless barrel with a hard-chrome plated 16 mm rod shrugs off damp, washdown-prone and outdoor conditions that quickly ruin painted-steel minis.
Because the body follows the JIS mini-cylinder standard, standard JIS brackets and I/Y rod knuckles bolt straight on - a real spares and design win. The fitted magnet means CMSG, DMSG or EMSG switches can be mounted for end-position sensing without reordering. For planning: at 0.5 MPa the push force works out to roughly 64 kgf, so halving for a 2:1 margin lets this cylinder lift about 32 kg vertically with confidence. Note that when air is lost the piston drifts freely - for a held load, add an external rod lock or a pilot check valve.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG40X200S Is Used
Pallet clamp actuation
Clamping and releasing palletised loads on warehouse transfer stations, where the 628.3 N push at 0.5 MPa seats clamps firmly and the stainless barrel survives cold-store washdown.
Bottle-line pusher gates
Kicking off-spec bottles or cartons off a food-line conveyor; the SUS304 body and hard-chrome rod handle frequent wet cleaning, and the magnet feeds a CMSG switch to confirm each push.
Small press ejection
Ejecting formed parts from a benchtop stamping die, with the bumper pad absorbing the return stroke and the 200 mm stroke clearing deep die cavities.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG40X200S the Right Cylinder?
At 628.3 N push (0.5 MPa) this is the top of the MG ladder; if your load needs under about 343 N, the MG32X200S saves space and air, while heavier or faster duty belongs on the cushioned MGC50. The 200 mm stroke sits well inside the 500 mm standard range, so no made-to-order lead time applies. With a 200 mm stroke on a 16 mm rod, keep side loads low and guide the workpiece externally if the tooling overhangs. Match the mount to the job - LB foot, FA flange, CB clevis or SDB pivot - and remember the -S magnet is already fitted for sensor use.

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/impact settings and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MG Stainless Steel Mini Air Cylinder MG40X200S FAQ
Push is 628.3 N and pull 527.8 N at 0.5 MPa; at 0.7 MPa push rises to 879.6 N and pull to 738.9 N, with a theoretical maximum of 128.1 kgf at 1.0 MPa. It is a double acting JIS round-body mini cylinder, 40 mm bore, 200 mm stroke, 16 mm rod with M14x1.5 male thread, 1/8" ports, operating on 0.15-1.0 MPa (22-145 psi) filtered air at 30-800 mm/s, from -20 to +70 C.
Yes - the S in the model code means the piston magnet is factory-fitted, so AirTAC CMSG, DMSG or EMSG reed/electronic switches clamp directly onto the stainless barrel to signal rod position. Without the magnet option a switch cannot detect the piston, so this SKU is sensor-ready out of the box.
