The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X200-100 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 200mm 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 on-site with the AirTAC MFCJ32X200-100, a JIS-standard round-body mini cylinder featuring a 100 mm adjustable extend window. The external needle shortens the forward stroke from its 200 mm nominal length, while the variable air cushion at both ends absorbs high-speed shock for smooth deceleration. A SUS304 stainless barrel and riveted aluminium covers keep the build compact and lighter than a tie-rod unit.
This 32 mm bore double-acting actuator pushes with 402.2 N at 0.5 MPa, yielding a safe working load of roughly 241 N or a 20.5 kg vertical lift with a 2:1 margin. It uses a 1/4" port and a 12 mm rod. Note that this SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors. The cushion only decelerates the piston near stroke end and does not lock the load.

| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
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.
Fine-tune the 200 mm extend stroke down by up to 100 mm to set precise feeding depths on machining lines, using the 402.2 N push force to drive light tooling heads.
Leverage the variable air cushion to decelerate rapid package-routing strokes smoothly, preventing end-cap shock while hitting varying lane positions on the fly.
Lift roughly 20.5 kg of goods vertically, adjusting the extend endpoint during commissioning to accommodate different pallet heights without swapping cylinders.
When sizing this series, compare the real thrust: the 32 mm bore provides 402.2 N push at 0.5 MPa, whereas stepping up to the MFCJ40 delivers 628.3 N. Choose the 32 mm bore for lighter, faster changeovers where the 100 mm adjustment window lets you tune trial fits without machining. Mount via LB foot, FA flange, or TC trunnion (SDB is unavailable).
Because this is a non-magnet SKU, position sensing is impossible without switching to an -S variant. Remember that the air cushion and stroke adjuster manage end-of-travel shock and position, but they do not hold the load on air loss. For vertical or suspended loads that must resist drift, add an external rod lock or pilot check valve.
Quick checklist
This 32 mm bore cylinder uses a 1/4" port and a 12 mm rod with an M10x1.25 male thread. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, or 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
This specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG switches; you need an -S variant for sensing. The external adjuster shortens the extend stroke by up to 100 mm on-site, and the variable air cushion at both ends decelerates the piston near the stroke ends but does not lock the load.
