Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X150SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X150SCM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 150mm 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 MFC40X150SCM
Delivering up to 879.6 N of push force at 0.7 MPa, this 40 mm bore double-acting mini cylinder handles demanding actuation with ease. The MFC40X150SCM features a variable air cushion at both ends, allowing you to dial in a needle valve to absorb high-speed end-of-stroke shock, thereby protecting the payload and reducing noise. Built with a SUS304 stainless barrel and riveted aluminium covers, the JIS-standard round-body construction resists mild corrosion and washdown environments. Furthermore, for the same bore and stroke, the MFC body is notably shorter than an ISO 6432 cylinder, saving valuable mounting length without sacrificing power.
Equipped with a 1/4" port and a 16 mm piston rod, this unit is designed for robust performance. The SKU includes the -S magnet, enabling seamless integration with CMSG, DMSG, or EMSG electronic switches for position sensing, and features a CM round-end rear cover. For practical sizing, the computed safe working load is approximately 377 N, meaning it can lift about 32 kg vertically with a 2:1 safety margin. Operating efficiently between 30-800 mm/s, it relies on its adjustable cushion to decelerate heavy loads smoothly near stroke end.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X150SCM Is Used
Heavy Package Diversion
Ideal for routing heavier cartons on a distribution line where the variable air cushion smoothly halts the 150 mm stroke at high cycle rates without jarring the products.
Clamping Large Castings
Provides the substantial 628.3 N push force at 0.5 MPa needed to secure bulky metal components during machining, while the SUS304 barrel withstands cutting fluid splashes.
Vertical Lift Gates
Lifts about 32 kg vertically with a 2:1 safety margin, making it suitable for actuating lightweight access panels or material handling gates that require reliable position feedback via the -S magnet.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X150SCM the Right Cylinder?
When sizing this 40 mm bore actuator, evaluate your force requirements carefully. If your application only needs 402.2 N of push force at 0.5 MPa, stepping down to the MFC32 will save space and air consumption. However, if you require the full 628.3 N push at 0.5 MPa (or 879.6 N at 0.7 MPa), this model is the largest available in the MFC series and is the correct choice for heavier payloads.
The variable air cushion is essential when operating at high speeds or moving substantial mass, as it prevents harsh impacts at the stroke extremes. Keep in mind that the cushion only decelerates the piston near the end of travel; it does not function as a brake or lock. If your system loses air pressure or the valve is centered, the piston will drift, so you must incorporate an external rod lock or pilot-operated check valve to hold a suspended load safely. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion brackets to suit your layout.
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 MFC40X150SCM FAQ
This 40 mm bore double-acting cylinder features a 1/4" port and a 16 mm rod. It delivers a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa. At 0.7 MPa, the push force is 879.6 N and the pull force is 738.9 N. The theoretical maximum force is 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 lock or brake. If air is lost, the piston will drift. To hold a load securely, you must use an external rod lock or a pilot-operated check valve. The -S magnet in this model allows use with CMSG, DMSG, or EMSG switches for position confirmation.
