Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X25SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X25SCM 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 MFC40X25SCM
Delivering 628.3 N of push force at 0.5 MPa, this double-acting stainless steel mini cylinder handles heavy loads in tight spaces. The MFC40X25SCM features a JIS-standard round-body design with a SUS304 barrel and riveted aluminium covers. For the same 40 mm bore and 25 mm stroke, the body is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length without sacrificing power.
A defining trait of the MFC series is the variable air cushion at both ends. By turning a needle valve, you tune the end-of-stroke deceleration to absorb high-speed shock, protecting your machinery and reducing noise far better than a fixed rubber bumper. The -S in the model code denotes a built-in piston magnet, enabling direct mounting of CMSG, DMSG or EMSG sensors for position feedback. With a practical safe working load of roughly 377 N, it can vertically lift about 32 kg with a 2:1 safety margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X25SCM Is Used
Heavy Carton Diverting
Provides robust 628.3 N push force to deflect heavy packaged goods on high-speed sorting lines, using the tuned air cushion to halt the 25 mm stroke silently without jarring the belt.
Press Fit Tooling
Drives small bearing housings into machined fixtures, relying on the 40 mm bore power and the adjustable end-cushion to prevent impact damage to delicate components on contact.
Pallet Stopper Gate
Acts as a heavy-duty stopping gate for loaded pallets, where the SUS304 stainless barrel resists workshop dust and the cushion needle absorbs the kinetic energy of the arriving load.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X25SCM the Right Cylinder?
When sizing this 40 mm bore actuator, consider the full force spectrum: it pushes 628.3 N and pulls 527.8 N at 0.5 MPa, escalating to 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical ceiling of 128.1 kgf at 1.0 MPa. If your application is lighter, stepping down to the MFC32 yields 402.2 N at 0.5 MPa; since 40 mm is the largest bore in this series, heavier demands will require a different cylinder family entirely.
The adjustable air cushion proves invaluable when cycling heavy masses at high speeds, letting you dial in the exact deceleration needed to prevent end-cap slamming. Remember that the cushion only slows the piston near the stroke end—it does not function as a lock or brake. If air pressure drops, the piston will drift, so fit an external rod lock or pilot check valve for suspended loads. This specific SKU includes the CM round-end rear cover and the -S magnet for switches, while the 1/4 inch port handles the necessary airflow.
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 MFC40X25SCM 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, 879.6 N push and 738.9 N pull at 0.7 MPa, and a theoretical maximum of 128.1 kgf at 1.0 MPa.
No, the variable air cushion only decelerates the piston near the end of the stroke to reduce shock; it is not a brake or locking mechanism. If air pressure is lost or the valve is centered, the piston will drift, so you must use an external rod lock or pilot-operated check valve to suspend a load safely.
