Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X250CA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X250CA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 250mm 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 MFC40X250CA
Delivering 628.3 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavy-duty motion within a compact footprint. The MFC40X250CA features a 40 mm bore, a 250 mm stroke, and a CA rear pivot cover. Its SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown environments, while the JIS-standard body is noticeably shorter than a comparable ISO 6432 cylinder, saving valuable mounting length.
A defining trait of the MFC series is the variable air cushion at both ends, which uses a needle valve to absorb high-speed end-of-stroke shock, protecting your load and reducing noise versus a simple bumper. Driven by a 1/4" port and a 16 mm rod, it provides a safe working load of roughly 377 N, lifting about 32 kg vertically with a 2:1 margin. Note this SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X250CA Is Used
Heavy Package Diversion
Uses the 628.3 N push force to deflect heavy cartons on a high-speed sorting line, relying on the variable air cushion to silently stop the 250 mm stroke without slamming.
Pallet Flap Folding
Drives large cardboard flaps down during automated palletizing, where the 1/4" port delivers enough volume to complete the 250 mm travel quickly and the cushion prevents tearing the material.
Vertical Lift Gate
Raises an access gate weighing roughly 32 kg, matching the computed vertical lift capacity safely while the CA pivot mount accommodates the shifting load geometry.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X250CA the Right Cylinder?
When sizing this 40 mm bore, stepping down to the MFC32 yields 402.2 N of push force at 0.5 MPa, which is insufficient if you need the full 628.3 N available here; since 40 mm is the largest MFC bore, moving beyond this capacity requires a different cylinder family entirely. The adjustable air cushion is essential when cycling heavy loads at high speeds, allowing you to dial in the deceleration to prevent impact damage. Keep in mind the cushion only slows the piston near the stroke end and does not act as a brake; if you need to hold a load vertically during air loss, install an external rod lock or pilot check valve. For mounting, the CA back cover pairs with standard options like LB foot or FA flange, and you must select an -S variant if your application requires 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 MFC40X250CA FAQ
This 40 mm bore cylinder features a 1/4" port and a 16 mm 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, with a theoretical maximum force of 128.1 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet option, meaning it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing, though all MFC models share the SUS304 stainless build and the variable air cushion for shock absorption.
