Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X175CM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X175CM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 175mm stroke, 1/4" air ports and a SUS304 stainless-steel barrel for mildly corrosive environments. For the same bore and stroke it is shorter than an ISO 6432 cylinder, saving mounting space.

About the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X175CM
Delivering 628.3 N of push force at 0.5 MPa, the AirTAC MFC40X175CM is a JIS-standard round-body mini cylinder built for demanding actuation. The 40 mm bore pairs a SUS304 stainless steel barrel with riveted aluminium covers to resist mild corrosion and washdown environments, while the CM round-end rear cover completes the compact assembly. A 1/4" port supplies the double-acting piston, which travels a 175 mm stroke at speeds between 30 and 800 mm/s.
The defining feature of this MFC variant is the variable air cushion at both ends, allowing you to turn a needle valve to soak up high-speed end-of-stroke shock and protect the load. For the same bore and stroke, this riveted body is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length. In practical terms, it yields a safe working load of roughly 377 N, meaning it can lift about 32 kg vertically with a 2:1 safety margin. Note that this specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG position switches.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X175CM Is Used
Package Diversion
Handles heavy carton diverting on packaging lines where the 628.3 N push force easily pushes bulky goods across transfer plates without stalling.
Press Ejection
Ejects dense metal or plastic parts from a press bed, using the adjustable air cushion to decelerate the 175 mm stroke and prevent slamming at full extension.
Pallet Stopper
Acts as a robust pneumatic stop for loaded pallets on roller conveyors, relying on its SUS304 stainless construction to endure dusty industrial settings.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X175CM the Right Cylinder?
When sizing this 40 mm bore model, consider the next size down: the MFC32 provides 402.2 N of push force at 0.5 MPa, making it a lighter alternative if your load permits. Since 40 mm is the largest available bore in this series, you cannot step up further within the MFC family for heavier demands. The variable air cushion is essential when cycling heavy loads at high speeds, as it decelerates the piston near the stroke end to reduce impact noise. Remember that the air cushion only slows the piston and does not act as a brake; the cylinder will drift and lose its load if air pressure drops or the valve is centered. For suspended or gravity-loaded applications, install an external rod lock or a pilot-operated check valve. Furthermore, because this configuration lacks the -S suffix, it has no internal magnet and cannot support magnetic sensing.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/CM) & mount (LB/FA/SDB/TC)
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 Use correct back cover (CA/U/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X175CM FAQ
This 40 mm bore double-acting cylinder uses a 1/4" air port and a M14x1.5 male rod thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, increasing to 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet option, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for position sensing. The cylinder does feature a variable air cushion at both ends to absorb shock, but this only decelerates the piston near the stroke end and does not hold the load on air loss.
