The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X30-20S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 30mm 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 shock with the AirTAC MFCJ32X30-20S. This double-acting JIS-standard round-body mini cylinder uses an external adjuster to shorten the extend stroke by up to 20 mm on-site, while needle variable air cushions at both ends soak up end-of-stroke impact. The SUS304 stainless steel barrel and riveted aluminium covers deliver mild washdown resistance without the bulk of a tie-rod body.
Delivering 402.2 N of push force at 0.5 MPa, this 32 mm bore unit is built for precise trial fits. It features a 1/4" port, a 12 mm rod with an M10x1.25 male thread, and a built-in magnet (-S) for CMSG, DMSG or EMSG sensors. The compact JIS body is shorter than an ISO 6432 cylinder of the same size, saving valuable mounting length. Expect a safe working load around 241 N, or roughly 20.5 kg of vertical lift with a 2:1 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.
Tune the 20 mm extend window to set precise contact depth on delicate bearings, letting the variable air cushion absorb the 402.2 N impact for quiet operation.
Dial in the exact stroke length on-site to accommodate different package sizes, using the needle cushion to prevent harsh slamming during rapid 30-800 mm/s cycling.
Leverage the 241 N safe working load and compact JIS body to fit tight test cells, making trial fits easy while CMSG sensors confirm the exact end position.
Selecting the right bore means sizing both ways against the real thrust figures. If 245.3 N from an MFCJ25 is too weak, this MFCJ32 provides 402.2 N at 0.5 MPa; stepping up to an MFCJ40 yields 628.3 N but demands more space. The 20 mm adjustable window here is perfect for high-speed changeovers where the exact extend position and end-of-stroke shock both need on-the-fly tuning. Mount via LB foot, FA flange, or TC trunnion (there is no SDB or back-cover option). The -S magnet enables CMSG/DMSG/EMSG switches for position confirmation. Remember that the air cushion only decelerates the piston near the end of stroke—it is not a lock. The cylinder will drift on air loss, so add an external rod lock or pilot check valve if you need to hold a suspended load.
Quick checklist
This 32 mm bore cylinder has a 1/4" port. 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 of 82 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 20 mm on-site, giving a usable extend range of 10-30 mm. Needle variable air cushions at both ends decelerate the piston at high speed. The -S suffix means it includes a magnet for CMSG, DMSG or EMSG sensors.
