Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X75U
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X75U is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 75mm 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 MFC40X75U
Delivering 628.3 N of push force at 0.5 MPa, the AirTAC MFC40X75U is a JIS-standard round-body mini cylinder built for demanding, high-speed tasks. It features a SUS304 stainless steel barrel with riveted aluminium covers, resisting mild corrosion and washdown environments. For the same bore and stroke, this riveted construction is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length without sacrificing power.
The defining feature of this double-acting unit is the variable air cushion at both ends, allowing you to turn a needle to soak up end-of-stroke shock and cut noise at high speeds. Operating at 30-800 mm/s via a 1/4 inch port, it delivers a theoretical maximum force of 128.1 kgf. Based on the 0.5 MPa push rating, it handles 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 MFC40X75U Is Used
Package Diverting
Uses the 628.3 N push force to deflect heavy cartons at high speed, with the adjustable air cushion preventing harsh impacts at the 75 mm stroke end.
Vertical Lowering
Safely lowers 32 kg payloads with a 2:1 safety margin, relying on the needle-set cushion to decelerate the load smoothly before reaching the bottom.
Box Forming Press
Drives forming plates with 879.6 N at 0.7 MPa, where the SUS304 barrel withstands occasional washdowns and the compact body fits tight machine frames.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X75U the Right Cylinder?
When sizing this 40 mm bore model, step down to the MFC32 if your application only requires 402.2 N of push force at 0.5 MPa, as this is the largest standard bore available in the series. The adjustable air cushion is essential when moving heavy loads at high velocity, letting you fine-tune the deceleration to protect your machinery. Keep in mind the cushion only decelerates the piston near the stroke end; it does not function as a brake. If you need to prevent drift on air loss, install an external rod lock or pilot check valve.
This specific MFC40X75U configuration includes a U-style flat-end back cover and a male M14x1.5 rod thread. Because this SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG magnetic switches for position 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 MFC40X75U FAQ
This 40 mm bore cylinder uses a 1/4 inch port. At 0.5 MPa it pushes 628.3 N and pulls 527.8 N. At 0.7 MPa it pushes 879.6 N and pulls 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet, so it cannot support CMSG, DMSG, or EMSG switches. You would need the -S variant for position sensing.
