Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X25UTC
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X25UTC is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 25mm 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 MFC40X25UTC
Delivering 628.3 N of push force at 0.5 MPa, the AirTAC MFC40X25UTC is a robust JIS-standard round-body mini cylinder built for demanding short-stroke tasks. A variable air cushion at both ends allows you to dial in the needle valve to absorb end-of-stroke shock at high speeds, protecting your payload far better than a fixed rubber bumper. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown, while the U flat-end rear cover and TC trunnion mounting provide stable pivot installation.
This double-acting actuator uses a 1/4" port and a Ø16 mm piston rod with an M14x1.5 male thread. For the same bore and stroke, the MFC body is noticeably shorter than an ISO 6432 cylinder, saving valuable machine space without sacrificing power. Based on the 0.5 MPa push rating, it handles a safe working load of about 377 N, lifting roughly 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 MFC40X25UTC Is Used
Short-Stroke Stamping
Leveraging its 628.3 N push force and 25 mm stroke to execute rapid, high-impact stamping operations where the variable air cushion prevents harsh mechanical slamming.
Heavy Diverting
Pivoting via the TC trunnion to push heavier product streams on a packaging line, using the 1/4" port flow to maintain fast 30-800 mm/s cycling.
Pallet Stopper
Halting loaded pallets in washdown zones; the SUS304 stainless barrel resists moisture while the needle-set cushion absorbs the kinetic energy of the arriving load.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X25UTC the Right Cylinder?
When sizing this 40 mm bore, step down to the MFC32 if your application only requires 402.2 N of push force at 0.5 MPa, as no larger MFC bore exists for heavier demands. The adjustable air cushion is essential when cycling at high speeds or moving substantial masses, as it decelerates the piston smoothly near the end of travel. Remember that this cushion only slows the load and does not function as a lock or brake; the piston will drift if air pressure drops or the valve is centered. To hold a load securely in place, install an external rod lock or a pilot-operated check valve alongside the cylinder.
The included TC trunnion mount pairs well with the U flat-end back cover for pivoting loads, and the 1/4" port ensures adequate flow for the 30-800 mm/s speed range. If your assembly requires automated position feedback, you must select the -S magnet variant to enable CMSG, DMSG, or EMSG sensors, as this base model cannot support them.
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 MFC40X25UTC FAQ
This 40 mm bore cylinder features a 1/4" port and a Ø16 mm rod. At 0.5 MPa it provides 628.3 N push and 527.8 N pull force. At 0.7 MPa it delivers 879.6 N push and 738.9 N pull. 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 SUS304 stainless barrel and a variable air cushion at both ends to decelerate loads smoothly.
