The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X10SU is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 10mm 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, the AirTAC MFC40X10SU is a JIS-standard round-body mini cylinder built for rapid, shock-sensitive tasks. A variable air cushion at both ends lets you dial in the needle valve to smoothly decelerate the payload near stroke end, cutting noise and impact far better than a fixed rubber bumper. The riveted aluminium covers and SUS304 stainless barrel resist mild corrosion and washdown environments.
Driven by a 40 mm bore and a 10 mm stroke, this double-acting actuator uses a two-way oil-retaining seal alongside a front cover anti-impact pad. It features a U flat-end back cover and a 1/4" port. Because the -S suffix denotes a built-in piston magnet, you can mount CMSG, DMSG or EMSG reed and electronic switches directly for position sensing. For the same bore and stroke, the MFC body is shorter than an ISO 6432 cylinder, saving valuable mounting length without conforming to that standard.

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.
Uses the 628.3 N push force to knock small metal or plastic parts out of a die rapidly, relying on the adjustable air cushion to silently absorb the 10 mm stroke impact.
Quickly pushes lightweight cartons off a packaging line, with the needle-set cushion preventing harsh slams at the end of the brief 10 mm travel.
Acts as a compact 40 mm bore barrier for pallets, using the U flat-end back cover and riveted stainless construction to withstand industrial warehouse traffic.
When sizing this 40 mm bore, step down to the MFC32 if your task requires less thrust, as it provides 402.2 N push force at 0.5 MPa. Since 40 mm is the largest bore in the MFC family, you cannot size up within this series. Tuning the variable air cushion is critical when cycling heavy loads at high speeds up to 800 mm/s, as it absorbs end-of-stroke shock. A safe working load is approximately 377 N, or about 60 percent of the 0.5 MPa push figure. In a vertical lift scenario, it handles roughly 32 kg with a 2:1 safety margin. Remember that the cushion only decelerates the piston; it does not function as a lock or brake. If air pressure drops, the piston will drift, so fit an external rod lock or pilot-operated check valve for secure load holding. The included -S magnet supports CMSG, DMSG and EMSG sensors, and you can mount it via LB foot, FA flange, SDB pivot or TC trunnion.
Quick checklist
This double-acting 40 mm bore cylinder has a 1/4" port and an M14x1.5 male rod thread. It delivers 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 force of 128.1 kgf at 1.0 MPa.
No, the variable air cushion only decelerates the piston near the stroke end and never acts as a lock or brake. If air is lost, the piston will drift, so you must use an external rod lock or pilot check valve to hold a suspended load. The -S magnet enables CMSG, DMSG or EMSG switches to confirm position.
