Airtac MF32-40 Stainless Steel Mini Cylinder MF32X290SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X290SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 290mm 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.

About the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X290SCM
Generating 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles substantial work within a compact footprint. Its SUS304 stainless-steel barrel and riveted aluminium covers resist mild corrosion and washdown environments. The piston relies on a two-way oil-retaining seal for long life, while fixed TPU bumper pads soften stroke-end impact. Because the MF body is shorter than an ISO 6432 cylinder for the same bore and stroke, it saves valuable mounting length.
Featuring a 290 mm stroke and a 1/4" port, the unit includes a built-in piston magnet (-S) for CMSG, DMSG, or EMSG sensors, and a CM round-end rear cover. Plan for a safe working load of about 241 N, which is roughly 60% of the 0.5 MPa push rating. Alternatively, it can vertically lift about 20.5 kg with a 2:1 safety margin, letting you match real part weights directly.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X290SCM Is Used
Carton Diverter Arms
Pushes packages at 90 degrees across a packaging line using the 402.2 N thrust, while the 290 mm stroke reaches across the belt width.
Vertical Parts Lift
Raises lightweight tote bins weighing up to 20.5 kg between conveyor tiers, taking advantage of the compact JIS body length.
Clamp Actuation
Secures aluminium extrusions in a machining fixture, using the 1/4" port for rapid fill and the TPU pads to absorb clamping shock.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X290SCM the Right Cylinder?
When sizing this 32 mm bore, the adjacent MF25 provides 245.3 N at 0.5 MPa, while the larger MF40 yields 628.3 N at 0.5 MPa. If your air supply drops or the valve centres, a standard cylinder cannot hold a load and the piston will drift; the fixed bumpers only decelerate the end of travel and act as neither a lock nor a brake. For suspended loads, specify an external rod lock or a pilot-operated check valve. The CM round-end back cover suits pivot mountings, and the -S magnet enables position sensing.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MF32-40 Stainless Steel Mini Cylinder MF32X290SCM FAQ
This 32 mm bore cylinder has a 1/4" port and an M10x1.25 male rod thread. 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 riveted SUS304 stainless barrel makes the body shorter than an ISO 6432 unit for the same 290 mm stroke. The -S suffix means it has a piston magnet for CMSG, DMSG, or EMSG switches, and the CM back cover provides a round-end pivot mount.
