Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X300SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X300SCA 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 MFC40X300SCA
Delivering 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore mini cylinder tackles heavy loads with a 300 mm stroke. The MFC40X300SCA features a variable air cushion at both ends, allowing you to dial in a needle valve to absorb high-speed end-of-stroke shock, protecting your machinery and reducing noise compared to simple bumper designs. Its JIS-standard round-body construction uses a SUS304 stainless steel barrel with riveted aluminium covers, offering excellent mild corrosion and washdown resistance.
For the same bore and stroke, this riveted stainless body is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting space without sacrificing power. Equipped with a CA rear pivot cover and a 1/4 inch port, it handles pressures up to 1.0 MPa. In practical terms, it provides a safe working load of about 377 N, meaning it can lift roughly 32 kg vertically with a 2:1 safety margin. Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG, or EMSG position switches.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X300SCA Is Used
Heavy Package Diversion
Uses the 628.3 N push force to positively deflect heavy cartons at high speed onto a secondary line, with the variable air cushion preventing harsh slams at the 300 mm stroke end.
Vertical Material Lowering
Safely lowers 25 kg fixtures down a 300 mm drop, relying on the adjustable cushion to decelerate the load smoothly before the bottom cover.
Pallet Flap Folding
Drives thick cardboard flaps down on oversized pallets, where the 40 mm bore provides the necessary torque and the CA pivot allows angular self-alignment.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X300SCA the Right Cylinder?
When sizing this 40 mm bore, check both directions: stepping down to the MFC32 drops the 0.5 MPa push force to 402.2 N, while the MFC40X300SCA represents the maximum standard bore in this series. Choose this model when moving heavier payloads at high cycling speeds, as the adjustable air cushion is essential for smoothing out aggressive stops. Keep in mind the cushion only decelerates the piston near the stroke end; it does not function as a brake. If your application must hold a vertical load during air loss or valve centering, the piston will drift, so you must add an external rod lock or pilot-operated check valve.
Mounting is handled via the integrated CA rear pivot, ideal for clevis setups. The -S suffix means a piston magnet is pre-installed, letting you directly mount CMSG, DMSG, or EMSG sensors without further modification.
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 MFC40X300SCA FAQ
This 40 mm bore cylinder uses a 1/4 inch port and a 16 mm rod with an M14x1.5 male thread. At 0.5 MPa it pushes 628.3 N and pulls 527.8 N. At 0.7 MPa it pushes 879.6 N and pulls 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
The variable air cushion only decelerates the piston near the end of stroke; it is not a lock or brake, so the cylinder cannot hold a load on air loss and will drift. Use an external rod lock or pilot check valve for holding. This model includes the -S magnet for CMSG, DMSG, and EMSG switches.
