Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X85SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X85SCA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 85mm 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 MFC40X85SCA
Delivering up to 879.6 N of push force at 0.7 MPa, this double-acting 40 mm bore mini cylinder is built for heavy-duty automation. The MFC40X85SCA features a variable air cushion at both ends, letting you dial in a needle valve to absorb high-speed end-of-stroke shock, protecting your payload and cutting workshop noise. Its SUS304 stainless round 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 a typical ISO 6432 cylinder, saving valuable machine space without sacrificing power. Equipped with a 1/4" port and an M14x1.5 male rod thread, it provides a safe working load of about 377 N (roughly 60% of the 0.5 MPa push force). With the -S magnet and CA rear pivot cover installed, it supports CMSG, DMSG, and EMSG position sensing right out of the box.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X85SCA Is Used
Heavy Package Diversion
Lifts about 32 kg vertically with a 2:1 safety margin, ideal for actuating heavy-goods diverters on high-speed sorting conveyors where the variable cushion halts the 85 mm stroke smoothly.
Press Ejection
Generates 879.6 N of push at 0.7 MPa to eject dense machined components from a press bed, using the adjustable end-cushioning to prevent damage to finished surfaces.
Pallet Stopper Arm
Acts as a robust shock-absorbing stop arm for loaded pallets, relying on the SUS304 stainless barrel to withstand dusty, mildly corrosive warehouse environments.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X85SCA the Right Cylinder?
When sizing this 40 mm bore unit, the next step down is the MFC32, which provides 402.2 N of push force at 0.5 MPa—suitable if your load is lighter. Because 40 mm is the largest bore in the MFC family, moving beyond the 628.3 N @0.5 MPa output of this model requires a different cylinder series entirely. Choose this variable-cushion version specifically when cycling at high speeds or moving heavy masses, as the adjustable needle deceleration prevents harsh impacts that a fixed bumper cannot absorb.
Keep in mind the air 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 a sudden air loss or when a valve is centered, the piston will drift, so you must add an external rod lock or a pilot-operated check valve. Mounting is straightforward via the built-in CA rear pivot, and the included -S magnet enables seamless switch integration.
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 MFC40X85SCA FAQ
This 40 mm bore cylinder features a 1/4" port and an M14x1.5 male rod thread. It delivers a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa. At 0.7 MPa, the push increases to 879.6 N and the pull to 738.9 N. 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 its stroke and does not act as a lock or brake. If air is lost or the valve is centered, the piston will drift. For vertical load-holding, you must install an external rod lock or a pilot-operated check valve. The -S magnet allows CMSG, DMSG, and EMSG sensors to track position.
