Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X25CA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X25CA 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 MFC40X25CA
Delivering 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore mini cylinder is built for heavy-duty shock absorption. The MFC40X25CA features a variable air cushion at both ends, letting you tune a needle valve to smoothly decelerate high-speed loads, drastically reducing end-of-stroke impact compared to fixed bumpers. Its JIS-standard round-body construction uses a SUS304 stainless steel barrel with riveted aluminium covers, yielding a total envelope that is physically shorter than an ISO 6432 cylinder of the same bore and stroke.
This specific configuration includes a CA rear pivot cover and a 25 mm stroke, making it highly effective for compact rotary actuation. It uses a 1/4" port and a 16 mm rod with an M14x1.5 male thread. Because this SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG magnetic switches. For sizing context, its safe working load is roughly 377 N, and it can vertically lift about 32 kg with a 2:1 safety margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X25CA Is Used
Short-Stroke Clamping
Ideal for securely gripping heavy castings, using the 628.3 N push force and 25 mm stroke to lock parts rapidly without over-travel.
High-Speed Diverting
Leverage the adjustable air cushion to swiftly push heavy pallets off a line, absorbing the sudden shock at the end of the 25 mm stroke.
Pallet Lift Stops
Deploy the CA pivot mount to arrest descending 30 kg loads smoothly, using the tuned cushioning to prevent harsh mechanical slams.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X25CA the Right Cylinder?
When sizing this 40 mm bore unit, consider the next size down: the MFC32 provides 402.2 N of push force at 0.5 MPa, offering a lighter footprint if your load permits. As 40 mm is the largest bore in the MFC series, you cannot step up within this family for higher thrust. The variable air cushion is essential if you are driving heavy payloads at high speeds, as it allows you to dial in the exact deceleration curve to protect your mechanics.
Note that the air cushion only decelerates the piston near the stroke end; it does not function as a brake or lock. If your application must hold a vertical load during air loss or valve centering, the piston will drift, requiring an external rod lock or pilot-operated check valve. Beyond the built-in CA pivot, you can adapt the body using LB foot, FA flange, SDB pivot-block, or TC trunnion mounts. If you need position sensing, select the -S magnet variant to enable switch 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 MFC40X25CA FAQ
This 40 mm bore double-acting cylinder has a 1/4" port and a 16 mm rod with an M14x1.5 thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum of 128.1 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches; you must choose the -S variant for sensing. The SUS304 stainless barrel resists mild corrosion, and the variable air cushion at both ends only decelerates the load near stroke end—it is not a lock.
