The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X60-50 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 60mm 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 extend lengths and absorb high-speed shock with the AirTAC MFCJ32X60-50. This JIS-standard round-body mini cylinder features a 50 mm adjustable window, allowing you to shorten the extend stroke on-site from its 60 mm nominal maximum down to 10 mm. A needle-set variable air cushion at both ends soaks up end-of-stroke kinetic energy for smooth, quiet deceleration.
Built with a SUS304 stainless barrel and riveted aluminium covers, it resists mild corrosion and washdown while maintaining a shorter mounting envelope than an ISO 6432 unit of the same bore. The 32 mm bore uses a 1/4" port and a 12 mm rod, delivering 402.2 N of push force at 0.5 MPa. This translates to a safe working load of about 241 N, or roughly 20.5 kg of vertical lift with a 2:1 margin. Note this SKU lacks the -S magnet, so it cannot host CMSG, DMSG, or EMSG sensors.

Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

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.
Perfect for packaging lines needing rapid format swaps; tweak the extend endpoint within the 50 mm window and set the needle cushion to handle the 402.2 N push force smoothly.
Ideal for lab automation where the exact stroke is unknown; shorten the 60 mm extend on the fly without swapping cylinders, relying on the air cushion to protect fragile payloads.
Drives lightweight routing flappers on conveyors, using its 241 N safe working load to push packages while the cushion prevents harsh banging at 800 mm/s.
When sizing this series, compare the real thrust outputs: the 32 mm bore yields 402.2 N push at 0.5 MPa, whereas stepping up to the MFCJ40 provides 628.3 N. Choose the 32 mm bore for lighter, faster changeovers where exact positioning and end-of-stroke shock both need field tuning. The 50 mm adjuster window is perfect for trial fits where the final extend point is not yet locked in.
Remember that the variable air cushion only decelerates the piston near the end of travel—it is not a lock or brake. If the load must be held during air loss, add an external rod lock or pilot check valve. For mounting, utilize LB foot, FA flange, or TC trunnion brackets (SDB and back-cover mounts are unavailable). Because this specific code has no -S suffix, magnetic sensing is unsupported.
Quick checklist
This 32 mm bore cylinder features a 1/4" port and a 12 mm rod. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum force of 82 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet, so it cannot host CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. The external adjuster shortens the extend stroke by up to 50 mm, but the variable air cushion only decelerates the piston; it does not lock the load.
