Airtac MF32-40 Stainless Steel Mini Cylinder MF32X250SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X250SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 250mm 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 MF32X250SCM
Delivering 402.2 N of push force at 0.5 MPa, this double-acting AirTAC MF32X250SCM mini cylinder is built around a JIS-standard round body. Its SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments. Because the MF body is shorter than an ISO 6432 cylinder for the same 32 mm bore and 250 mm stroke, it saves valuable mounting length in tight fixtures.
The piston relies on a heterogeneous two-way seal that retains an oil film for long service life, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts. Fitted with a CM round-end back cover and a 1/4" port, it includes a built-in magnet for position sensing. Plan for roughly 241 N of actual work at 0.5 MPa, which means it can safely lift about 20.5 kg vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X250SCM Is Used
Package Diverting
Pushes medium-weight cartons off a sorting line using 402.2 N of thrust, with the 250 mm stroke clearing guide rails completely.
Textile Loom Tensioning
Maintains consistent fabric tension via the CM round-end pivot, absorbing high-frequency stroke impacts through the fixed TPU pads.
Pallet Tag Applicator
Extends to press identification labels onto pallet loads, where the shorter JIS body prevents interference with overhead guards.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X250SCM the Right Cylinder?
If 245.3 N from the MF25 is insufficient, this 32 mm bore provides a solid step up; should you need even greater thrust, the MF40 offers 628.3 N at 0.5 MPa. Because the 250 mm stroke demands precise alignment to avoid rod-bending side loads, ensure your mounting—whether LB foot, FA flange, or TC trunnion—is perfectly square.
Note that a standard cylinder drifts when air is removed or a valve is centred; the TPU bumpers only decelerate the end of travel and act as neither a lock nor a brake. To suspend a load safely, install an external rod lock or a pilot-operated check valve. The included -S magnet allows direct mounting of CMSG, DMSG, or EMSG switches.
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 MF32X250SCM FAQ
At 0.5 MPa it pushes 402.2 N and pulls 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 model uses a 1/4" air port and an M10x1.25 male rod thread.
No, the piston will drift if air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not function as a braking lock. For vertical loads, you must add an external rod lock or pilot check valve. The CM round-end back cover and JIS compact body help with pivot mounting in tight spaces.
