Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X80SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X80SCM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 80mm 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 MFC40X80SCM
Delivering 628.3 N of push force at 0.5 MPa, this 40 mm bore double-acting mini cylinder handles heavy loads with precision. The MFC40X80SCM features a variable air cushion at both ends, allowing you to tune a needle valve to absorb end-of-stroke shock during high-speed operations. This protects your machinery and significantly reduces noise compared to fixed bumper designs.
Built with a SUS304 stainless steel barrel and riveted aluminium covers, the JIS-standard round-body construction resists mild corrosion and washdown environments. For the same bore and stroke, this cylinder is shorter than an ISO 6432 unit, saving valuable mounting space. It includes a built-in piston magnet for position sensing and a CM round-end rear cover. Based on the 0.5 MPa push rating, it provides a safe working load of roughly 377 N, lifting about 32 kg vertically with a 2:1 safety margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X80SCM Is Used
Heavy Package Diverting
Pushes dense cartons at high speed across transfer belts. The variable air cushion absorbs the 628.3 N push impact, preventing damage to the diverter arm and goods.
Press Ejection
Ejects formed metal or plastic parts from a press. The riveted SUS304 body withstands industrial shop environments while the cushion softens the rapid retraction stop.
Pallet Positioning
Lifts and indexes loaded pallets. With a safe vertical lift capacity of about 32 kg, the CM round-end rear cover provides stable pivot mounting for the motion.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X80SCM the Right Cylinder?
When sizing this 40 mm bore model, consider the force range: it delivers 628.3 N push at 0.5 MPa. If your application requires less force, stepping down to the MFC32 provides 402.2 N at the same pressure. As 40 mm is the largest available bore in this series, heavier loads beyond the 879.6 N push at 0.7 MPa will require a different cylinder family. The adjustable air cushion is essential when driving heavy payloads at high speeds, as it decelerates the piston smoothly.
Note that the air cushion only slows the piston near the stroke end and does not function as a brake. If your system must hold a load vertically during air loss or valve centering, the piston will drift; install an external rod lock or pilot-operated check valve. This MFC40X80SCM variant includes the -S magnet for CMSG, DMSG, or EMSG sensors. The 1/4" port and M14x1.5 male rod thread accommodate robust pneumatic connections and 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 MFC40X80SCM FAQ
This 40 mm bore double-acting cylinder has a 1/4" port and an M14x1.5 male rod thread. At 0.5 MPa it provides 628.3 N push and 527.8 N pull force. At 0.7 MPa it delivers 879.6 N push and 738.9 N pull. 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; it is not a lock or brake. The piston will drift if air is lost or the valve is centered. For holding loads, you must use an external rod lock or pilot check valve. The -S magnet allows CMSG/DMSG/EMSG sensors to confirm position.
