The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X160-10S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 160mm 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.
Dial in exact end positions and absorb high-speed shocks with the AirTAC MFCJ32X160-10S. This JIS-standard round-body mini cylinder features a 10mm external adjuster that shortens the extend stroke from its 160mm maximum, paired with a variable needle air cushion at both ends. The SUS304 stainless steel barrel and riveted aluminium covers deliver a shorter mounting envelope than an ISO 6432 unit while resisting mild washdown corrosion.
Generating 402.2N push force at 0.5MPa via a 1/4" port, it suits moderate load changeovers. The -S suffix provides a built-in magnet for CMSG, DMSG, or EMSG sensors. With a safe working load around 241N, it lifts about 20.5kg vertically with a 2:1 margin. Remember, the cushion only decelerates the piston; use an external rod lock to hold loads on air loss.

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 402.2N extend force to drive a small forming die, relying on the needle air cushion to decelerate the 160mm stroke smoothly and reduce end-impact noise.
Tunes the extend position within the 10mm window to deflect varying package sizes on a line, ensuring precise routing without repositioning the cylinder.
Lifts a 20kg access flap using the 0.5MPa push force, while the SUS304 barrel withstands humid dock environments and the cushion prevents slamming.
Choose the MFCJ32 over the MFCJ40 (628.3N at 0.5MPa) when your application needs 402.2N of push force rather than heavier thrust. Conversely, if the 32mm bore struggles to overcome friction, step up to the 40mm bore. The 10mm adjustable window is ideal for trial fits where the exact extend point must be trimmed on-site without machining new mounts.
Mounting options include LB foot, FA flange, and TC trunnion (no SDB or back-cover). Because this is an -S model, you can directly mount CMSG, DMSG, or EMSG switches for position feedback. The variable air cushion handles speeds from 30-800mm/s, but never rely on it as a brake; install a pilot check valve for load holding.
Quick checklist
This 32mm bore cylinder has a 1/4" port and M10x1.25 male rod thread. At 0.5MPa it pushes 402.2N and pulls 345.6N. At 0.7MPa it pushes 563N and pulls 483.8N. The theoretical maximum force is 82kgf at 1.0MPa.
The external adjuster shortens the extend stroke by up to 10mm on-site, while the retract stroke remains full length. The variable air cushion at both ends uses a needle valve to soak up high-speed end-of-stroke shock. Note that the -S magnet enables CMSG/DMSG/EMSG sensors, but neither the cushion nor the adjuster acts as a lock to hold the load.
