Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X75SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X75SCA 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 MFC40X75SCA
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder tackles heavy-duty actuation within a compact footprint. The riveted aluminium covers and SUS304 stainless steel barrel resist mild corrosion and washdown environments. For the same bore and stroke, the MFC body is notably shorter than an ISO 6432 cylinder, saving valuable mounting length without sacrificing power.
A variable air cushion at both ends lets you dial in a needle valve to absorb high-speed end-of-stroke shock, protecting your payload and cutting impact noise. The integrated -S piston magnet supports CMSG, DMSG, and EMSG switches for position sensing, while the CA rear pivot cover simplifies angular mounting. Driven by a 1/4 inch air port, it provides a safe working load of roughly 377 N, lifting about 32 kg vertically with a 2:1 safety margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X75SCA Is Used
Heavy Carton Diversion
Uses the 628.3 N push force to deflect heavy packaged goods on a high-speed sorting line, with the variable air cushion preventing harsh slams at the stroke end.
Vertical Press Lowering
Lowers a 32 kg assembly head smoothly, relying on the adjustable needle cushion to decelerate the mass before it reaches the bottom of the 75 mm stroke.
Component Seating
Presses bearings into housings on an automated jig, where the SUS304 barrel withstands mild coolant spray and the CA pivot accommodates slight misalignment.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X75SCA the Right Cylinder?
When sizing this 40 mm bore unit, step down to the MFC32 if your application only requires 402.2 N of push force at 0.5 MPa, as 40 mm is the largest available bore in the MFC series. The adjustable air cushion is essential if you are moving heavy loads at high cycling speeds, as it decelerates the piston near stroke end to prevent damaging shocks. Keep in mind the cushion only slows the load and does not act as a brake; the piston will drift if air pressure drops. For suspended or vertical loads that must hold position on air loss, fit an external rod lock or pilot-operated check valve. Pair the built-in magnet with CMSG, DMSG, or EMSG sensors, and utilise the CA pivot cover alongside LB, FA, SDB, or TC mounts to suit your frame.
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 MFC40X75SCA FAQ
This 40 mm bore cylinder features a 1/4 inch air port and a 16 mm piston rod with an M14x1.5 male 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, the variable air cushion only decelerates the piston near the stroke end and does not function as a lock or brake. If air pressure is lost, the piston will drift. To maintain position on suspended loads, you must install an external rod lock or pilot check valve. The -S magnet enables CMSG, DMSG, and EMSG sensors for end-of-stroke confirmation.
