Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X175SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X175SCM 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 MFC40X175SCM
Delivering 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore mini cylinder handles heavy loads with precision. A built-in piston magnet enables position sensing, while the CM round-end rear cover supports straightforward mounting. The 1/4" port and M14x1.5 male rod thread ensure robust pneumatic and mechanical connections.
Unlike basic bumper models, the MFC40X175SCM features a variable air cushion at both ends. You can tune a needle valve to decelerate high-speed strokes smoothly, protecting your machinery from end-of-travel shock. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown. For the same bore and stroke, this JIS-standard round body is noticeably shorter than an ISO 6432 cylinder, saving valuable machine space. It yields a safe working load of roughly 377 N, lifting about 32 kg vertically with a 2:1 margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X175SCM Is Used
Heavy Package Diversion
Pushes heavy cartons at high speed onto secondary packaging lines, using the tuned air cushion to prevent harsh impacts that could damage contents.
Press Ejection
Ejects dense metal or moulded parts from a press bed, relying on the 628.3 N push force and smooth end-of-stroke deceleration to protect tooling.
Pallet Stopper Gate
Acts as a high-force stop gate on a roller conveyor, absorbing the momentum of incoming pallets via the adjustable cushion rather than a rigid bumper.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X175SCM the Right Cylinder?
When sizing this 40 mm bore unit, consider the next size down: an MFC32 provides 402.2 N of push force at 0.5 MPa, making this MFC40X175SCM the correct choice if you need the full 628.3 N output. Since 40 mm is the largest available MFC bore, you cannot step up within this series. Choose this model specifically when moving heavy payloads at high cycling speeds, as the adjustable air cushions are essential for soaking up kinetic energy.
Remember that the air cushion only decelerates the piston near the stroke end; it does not function as a brake. If your application must hold a load vertically during air loss or valve centering, the piston will drift, so you must add an external rod lock or pilot-operated check valve. This SKU includes the -S magnet for CMSG, DMSG, or EMSG switches, and supports LB foot, FA flange, SDB pivot, or TC trunnion mounting.
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 MFC40X175SCM FAQ
This 40 mm bore cylinder features a 1/4" port and an M14x1.5 male rod thread. It delivers 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, the variable air cushion only decelerates the piston near the end of the stroke and acts purely as a shock absorber, never as a lock or brake. If air loss occurs or the valve is centered, the piston will drift. To maintain position, you must install an external rod lock or a pilot-operated check valve.
