About the Airtac MG Stainless Steel Mini Air Cylinder MG40X175
With a 40 mm bore and a 175 mm stroke, this MG cylinder is a double acting JIS round-body unit that pushes with 628.3 N and pulls with 527.8 N at 0.5 MPa, rising to 879.6 N on the extend stroke at 0.7 MPa. The barrel is SUS304 stainless steel riveted onto the covers, paired with a 16 mm hard-chrome plated rod, so the body shrugs off damp, washdown-prone and outdoor conditions that quickly ruin painted-steel minis. At the stroke ends a fixed anti-impact bumper pad softens the direction change; it decelerates only and is not an adjustable air cushion.
For sizing the load in practice, treat roughly 60% of the 0.5 MPa push rating as usable work, which is about 377 N, or plan vertical lifts around 32 kg with a 2:1 margin (the theoretical maximum at 1.0 MPa is 128.1 kgf). Running on 0.15-1.0 MPa (22-145 psi) filtered air at 30-800 mm/s, it accepts CMSG, DMSG or EMSG switches only when the optional S magnet is ordered - this SKU has no magnet, so no sensor can be fitted.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG40X175 Is Used
Carton press-down station
The 628.3 N push at 0.5 MPa seats flaps and presses cartons closed on a packaging line, while the bumper pad quiets the stroke-end impact at high cycling rates.
Pallet strapper clamp
A strapping head on a pallet wrapper uses the 879.6 N push at 0.7 MPa to tension and clamp banding, with the stainless barrel standing up to humid warehouse air.
Belt-line reject pusher
Mounted beside a conveyor, the 175 mm stroke sweeps off-spec bottles or cartons off the belt; the JIS footprint lets it bolt onto standard mini-cylinder brackets already on the frame.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG40X175 the Right Cylinder?
At 628.3 N push at 0.5 MPa, the 40 mm bore is the strongest in the MG range: step down to the 32 mm bore (402.2 N) if the load is lighter and you want a smaller envelope, or move to the cushioned MGC series if you need variable air cushioning and bores up to 63 mm. If your process must hold position when air is lost, remember this cylinder drifts once pressure drops - add an external rod lock or a pilot check valve. Mount it with LB foot, FA flange, CB clevis or SDB pivot brackets, and order the S code if position sensing with CMSG / DMSG / EMSG switches is planned. The 175 mm stroke is well inside the 500 mm standard limit, but keep side loads off the 16 mm rod on long travels to avoid premature seal wear.
Quick checklist
- ✓ Required force at your working pressure
- ✓ 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 MG40X175 FAQ
At 0.5 MPa it delivers 628.3 N push and 527.8 N pull; at 0.7 MPa, 879.6 N push and 738.9 N pull. The theoretical maximum is 128.1 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with proof pressure of 1.5 MPa (215 psi), and speed range is 30-800 mm/s on air filtered to 40 um.
Not as supplied - this SKU has no magnet. Order the S version (MG40X175S) to enable CMSG, DMSG or EMSG reed/solid-state switches. The body itself is a JIS-standard riveted round barrel in SUS304 stainless with a hard-chrome rod and a 1/8" port, and the fixed bumper pads only soften stroke-end impact; they do not hold or brake a load.
