Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X900SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X900SCM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 900mm 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 MFC40X900SCM
Delivering 628.3 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavy-duty actuation with precision. The 40 mm bore uses a 1/4 inch port and an M14x1.5 male rod thread to drive substantial loads. Because this specific 900 mm stroke exceeds the 500 mm standard maximum, it is manufactured as a made-to-order non-standard unit. A built-in piston magnet (-S) is included, enabling seamless integration with CMSG, DMSG, or EMSG reed and electronic switches for position sensing.
The defining feature of the MFC series is its variable air cushion at both ends, which uses a needle valve to absorb high-speed end-of-stroke shock, protecting your machinery and reducing noise far better than a simple bumper. The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments. For the same bore and stroke, the JIS-standard body is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length. Based on the 0.5 MPa push force, this model offers a safe working load of about 377 N, easily lifting roughly 32 kg vertically with a 2:1 safety margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X900SCM Is Used
Long-Stroke Diversion
Ideal for pushing heavy pallets across a wide conveyor belt using its 900 mm non-standard stroke and 628.3 N push force.
Vertical Material Lift
Lifts approximately 32 kg loads vertically in packaging lines, relying on the needle-set air cushion to prevent harsh bottoming impacts.
High-Bay Retrieval
Extracts totes from deep shelving units in storage systems, where the shorter JIS body length saves critical machine footprint.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X900SCM the Right Cylinder?
When sizing this 40 mm bore variant, consider stepping down to the MFC32, which provides 402.2 N of push force at 0.5 MPa for lighter payloads. Since 40 mm is the largest bore available in this series, you cannot size up within the MFC family; for forces exceeding the 879.6 N push at 0.7 MPa, a larger alternative cylinder family would be required. The variable air cushion is essential if you are moving heavy loads at high speeds, as it decelerates the piston smoothly to prevent impact damage. Note that the cushion only slows the piston near the stroke end and does not function as a lock; if your application must hold a load on air loss, install an external rod lock or pilot-operated check valve. This specific SKU features a CM round-end rear cover and includes the -S magnet for 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 MFC40X900SCM FAQ
This 40 mm bore cylinder features a 1/4 inch port and an M14x1.5 male rod 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. 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 and acts purely as a shock absorber, never as a brake or lock. The piston will drift on air loss or valve centring. You must use an external rod lock or pilot check valve to hold a load safely.
