Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X300SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X300SCM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 300mm 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 MFC40X300SCM
Delivering 628.3 N of push force at 0.5 MPa, the AirTAC MFC40X300SCM is a robust double-acting round-body mini cylinder built to JIS standards. Its riveted aluminium covers and SUS304 stainless steel barrel resist mild corrosion and washdown environments. For the same bore and stroke, this body is noticeably shorter than a standard ISO 6432 cylinder, saving valuable mounting length.
The defining feature of this 40 mm bore unit is the variable air cushion at both ends. By turning a needle valve, you tune the end-of-stroke deceleration to soak up high-speed shock, protecting the load and cutting noise. It uses a 1/4" port and a 16 mm rod with an M14x1.5 male thread. Factoring a 60% safety margin on the 0.5 MPa push force yields a safe working load of about 377 N, lifting roughly 32 kg vertically with a 2:1 margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X300SCM Is Used
Package Diverting
Handles heavy carton diversion on high-speed conveyors, using the tuned air cushion to stop the 300 mm stroke smoothly without jarring the mechanism.
Pallet Positioning
Shifts loaded pallets laterally at transfer stations, relying on the 628.3 N push force and SUS304 barrel to withstand dusty industrial environments.
Press Feed Ejection
Ejects dense metal blanks from a press bed, where the adjustable end cushions absorb kinetic energy to protect both the tooling and the workpiece.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X300SCM the Right Cylinder?
If 628.3 N at 0.5 MPa is excessive for your payload, stepping down to the MFC32 bore provides 402.2 N of push force; as 40 mm is the largest available MFC bore, you cannot size up within this family. The adjustable air cushion is essential when cycling this 300 mm stroke at high speeds or moving heavy masses, preventing harsh impacts. Remember that the cushion only decelerates the piston near the stroke end and does not function as a brake; if you need to hold a load vertically during air loss, install an external rod lock or pilot check valve. This configuration includes the -S magnet for CMSG, DMSG, or EMSG switches and features a CM round-end rear cover for flexible 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 MFC40X300SCM FAQ
This 40 mm bore double-acting cylinder uses a 1/4" port. 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, with a theoretical maximum of 128.1 kgf at 1.0 MPa.
No, the piston will drift on air loss. The variable air cushion only decelerates the piston near the end of stroke to reduce shock; it is not a lock or brake. For suspended loads, you must use an external rod lock or pilot-operated check valve.
