The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X100U is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 100mm 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.
Delivering 628.3 N of push force at 0.5 MPa, this 40 mm bore, 100 mm stroke mini cylinder brings variable air cushioning to heavy-duty applications. The needle-adjustable cushion at both ends absorbs end-of-stroke kinetic energy at high speeds, protecting payloads and reducing noise far better than a fixed rubber bumper. Its SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown environments.
Built to JIS standards, the riveted round-body design is notably shorter than an ISO 6432 cylinder of the same bore and stroke, saving valuable mounting length. Operating pressure spans 0.15 to 1.0 MPa, with a 1/4" port and an M14x1.5 male rod thread handling the substantial airflow. This specific configuration uses a U-style flat-end rear cover. Because this SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG position switches.

MF-family variants: MF / MFC (double acting ±cushion), MSF / MTF (single acting push / pull), MFD / MFCD (double rod ±cushion), MFJ / MFCJ (adjustable stroke ±cushion). Back covers CA / U / CM. Mounting LB / FA / SDB / TC.
Ideal for high-speed sorting arms pushing heavy cartons, where the variable air cushion smoothly stops the 100 mm stroke without slamming the payload.
Ejecting dense metal or plastic parts from a press bed using the robust 628.3 N push force, relying on the cushion to dampen the rapid retraction shock.
Actuating heavy stopper gates on pallet conveyors, where the U flat-end rear cover mounts flush and the stainless barrel withstands dusty industrial settings.
When sizing this 40 mm bore unit, step down to the MFC32 if your load requires less force—it yields 402.2 N push at 0.5 MPa. As 40 mm is the largest bore in the MFC family, moving up requires a different cylinder series entirely. Choose this MFC40X100U when operating at high speeds or moving heavy masses where the adjustable air cushion is essential to prevent end-of-stroke impact.
Remember that the air cushion only decelerates the piston near the stroke end; it is not a braking device. If your application must hold a vertical load during air loss or valve centering, the piston will drift, so you must fit an external rod lock or pilot-operated check valve. For position feedback, select the -S magnet variant to enable sensor mounting.
Quick checklist
This 40 mm bore cylinder features a 1/4" air 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 a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You must choose the -S variant for sensing capabilities. The variable air cushion at both ends only serves to decelerate the piston near stroke end and does not lock or hold the load.
