The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X100SCA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 100mm 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.
Generating 402.2 N of push force at 0.5 MPa, this double-acting AirTAC MF32X100SCA mini cylinder features a 32 mm bore and a 100 mm stroke. The JIS-standard round-body design is physically shorter than a comparable ISO 6432 cylinder, saving valuable mounting length in tight machinery. Because the base SKU includes an -S magnet, it is fully compatible with CMSG, DMSG, and EMSG reed or electronic switches for position sensing.
The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments. Fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impact, though they only decelerate rather than provide adjustable cushioning. For practical sizing, plan for a safe working load of roughly 241 N, which means it can vertically lift about 20.5 kg with a 2:1 safety margin. The 1/4 inch port and M10x1.25 male rod thread accommodate robust pneumatic flow for this force class.

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.
Actuates a routing gate on a packaging line, using the 100 mm stroke to push cartons onto secondary tracks without stalling the main belt flow.
Secures aluminium extrusions during CNC machining operations, applying steady 402.2 N clamping pressure at 0.5 MPa to prevent workpiece vibration.
Functions as a pneumatic stop in a low-profile roller conveyor system, holding loaded pallets in place for robotic wrapping before releasing them downstream.
When sizing this 32 mm bore unit, consider the MF25 which provides 245.3 N of push force at 0.5 MPa, or step up to the MF40 delivering 628.3 N if your application requires heavier movement. This model features a CA pivot back cover, making it ideal for clevis mounting configurations that accommodate angular rod movement. If your mechanism must maintain its vertical position during a compressed air loss or when the directional valve is centered, be aware that the piston will drift. You should integrate an external pilot-operated check valve or a dedicated rod lock to secure the load.
Quick checklist
At 0.5 MPa, the push force is 402.2 N and the pull force is 345.6 N. At 0.7 MPa, it pushes 563 N and pulls 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa. This 32 mm bore cylinder uses a 1/4 inch port and an M10x1.25 male rod thread.
No, the piston will drift if air is lost or the valve is centered, as the fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. To maintain a vertical load, you must install an external rod lock or a pilot-operated check valve.
