Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X150CA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X150CA 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 MFC40X150CA
Delivering 628.3 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavy-duty automation with precision. The MFC40X150CA features a variable air cushion at both ends; turning the cushion needle lets you dial in the deceleration to absorb high-speed end-of-stroke shock, protecting your payload far better than a fixed bumper. Built with a SUS304 stainless barrel and riveted aluminium covers, it resists mild corrosion and washdown environments.
For the same bore and stroke, this JIS-standard cylinder is noticeably shorter than an ISO 6432 unit, saving valuable machine space. It yields a safe working load of about 377 N (60% of its 0.5 MPa rating) and lifts roughly 32 kg vertically with a 2:1 safety margin. Equipped with a 1/4" port and an M14x1.5 male rod thread, this specific SKU lacks the -S magnet and therefore cannot host CMSG, DMSG, or EMSG sensors. The rear CA pivot cover simplifies direct mounting in pivoting assemblies.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X150CA Is Used
Heavy Carton Diversion
Pushes heavy packaged goods across high-speed sorting belts using its 628.3 N thrust, with the variable cushion preventing payload damage during rapid direction changes.
Press Ejection
Ejects dense stamped parts from a press bed, relying on the needle-set air cushion to decelerate the 16 mm rod smoothly and reduce machine vibration.
Pallet Stopper Arm
Acts as a robust stopper arm for inbound pallets, absorbing the kinetic energy of the load via the adjustable end cushions without bouncing.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X150CA the Right Cylinder?
When sizing this 40 mm bore, step down to the MFC32 if your application only requires 402.2 N of push force at 0.5 MPa, as no larger MFC bore exists for heavier loads. The adjustable air cushion is essential when cycling at high speeds or moving substantial masses, preventing harsh impacts at stroke ends. Keep in mind the cushion only decelerates the piston near the end of travel; it does not function as a lock or brake. If your system loses air, the piston will drift, so fit an external rod lock or pilot-operated check valve for suspended loads.
This model features a CA back cover for pivot mounting and a 1/4" air port. Because this base SKU is non-magnetic, position sensing is not possible here; you must specify the -S variant to use CMSG, DMSG, or EMSG switches.
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 MFC40X150CA FAQ
This 40 mm bore cylinder has a 1/4" 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, this specific SKU does not include the -S magnet, so it cannot support CMSG, DMSG, or EMSG switches. You must order the -S variant for position sensing. Additionally, its SUS304 stainless and aluminium construction offers excellent washdown resistance, and the CA rear cover provides a pivot mount.
