Airtac MG Stainless Steel Mini Air Cylinder MG40X200
The AirTAC Airtac MG Stainless Steel Mini Air Cylinder MG40X200 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 MG40X200
With a 40 mm bore pushing 628.3 N at 0.5 MPa (879.6 N at 0.7 MPa), the MG40X200 is the strongest round-body mini in the AirTAC MG range. It is a double acting JIS-standard cylinder with a 200 mm stroke, a 16 mm hard-chrome plated rod (M14x1.5 male thread) and a 1/8" port on every cover. The SUS304 stainless barrel is riveted to the covers and block, so the body shrugs off damp, washdown-prone spots that corrode painted-steel minis.
In practice, plan for roughly 377 N of usable push at 0.5 MPa, and expect the rod to lift about 32 kg vertically once you keep a 2:1 margin. The fixed anti-impact bumper pads soften the direction change at each stroke end but do not hold or brake a load - if the load must stay put when air is lost, add an external rod lock or a pilot check valve. Position feedback needs the -S magnet option, which enables CMSG, DMSG or EMSG switches; this SKU has no magnet, so no sensor can be fitted.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG40X200 Is Used
Pallet clamp actuation
Clamping and squaring palletised cartons on a warehouse transfer car, where the 628.3 N push at 0.5 MPa holds loads square without a separate clamp station.
Bottle line reject pusher
Kicking off-spec containers sideways on a bottling conveyor; the stainless barrel and chrome rod cope with constant washdown better than painted minis.
Small press ejection
Ejecting finished parts from a bench-top forming die, with the 200 mm stroke clearing the die area and the bumper pad damping the return.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG40X200 the Right Cylinder?
At 40 mm bore this is the top of the base MG line: 628.3 N push and 527.8 N pull at 0.5 MPa. If your load needs under about 402 N, the 32 mm bore (MG32X200) is cheaper and lighter; if you need more force or adjustable end-of-stroke deceleration, step up to the cushioned MGC series, which extends to 50 and 63 mm bores. The 200 mm stroke sits well inside the 500 mm standard range, so no made-to-order lead time applies.
Mount with LB foot, FA flange, CB clevis or SDB pivot brackets, and add I or Y rod knuckles on the tooling side. Because the 16 mm rod sees real bending moment at 200 mm of extension, keep side loads low or guide the load externally. This version carries no magnet, so order the S code if you plan to fit CMSG / DMSG / EMSG switches.

- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting (LB / FA / CB / SDB) & knuckle
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 MG40X200 FAQ
At 0.5 MPa it pushes 628.3 N and pulls 527.8 N; at 0.7 MPa those rise to 879.6 N push and 738.9 N pull. The theoretical maximum at 1.0 MPa is 128.1 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-800 mm/s, and the 1/8" port is the same on every MG bore.
No on both counts as supplied. The bumper pads only soften the stroke-end impact - they are not a brake, and the rod drifts if air is lost, so use an external rod lock or pilot check valve for a held load. This MG40X200 has no magnet, so CMSG, DMSG or EMSG switches cannot be mounted; order the S magnet option for sensing.
