Airtac MF32-40 Stainless Steel Mini Cylinder MF32X25CM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X25CM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 25mm 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 MF32X25CM
Delivering 402.2 N of push force at 0.5 MPa, this 32 mm bore double-acting actuator handles robust clamping tasks. The riveted rolling-packed structure joins the SUS304 stainless steel barrel to aluminium covers, resisting mild corrosion and washdown environments. A heterogeneous two-way seal retains an oil film for long piston life.
For the same 32 mm bore and 25 mm stroke, the JIS-standard body is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length in tight fixtures. Plan for about 241 N of actual work at 0.5 MPa, which means it lifts roughly 20.5 kg vertically with a 2:1 safety margin. Fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impact without offering adjustable cushioning.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X25CM Is Used
Stamping Pin Ejection
Uses the 25 mm stroke to rapidly eject small stamped metal pins from a die, relying on the 402.2 N push force to overcome die friction.
Bottle Sorting Diverter
Pushes lightweight plastic bottles into a secondary packaging lane, where the compact JIS body fits neatly within the conveyor frame.
Carton Flap Holders
Holds cardboard flaps stationary during automated taping, using the front anti-impact pad to prevent marking the packaging material.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X25CM the Right Cylinder?
When sizing this bore, the MF25 provides 245.3 N at 0.5 MPa, while the larger MF40 offers 628.3 N, allowing you to step up or down based on your exact force needs. This specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG reed switches for position sensing. The CM round-end back cover suits rear pivot mounting.
Because it is a standard double-acting cylinder, the piston will drift if air pressure drops or the valve is centred; the TPU pads only decelerate the stroke end and do not function as a brake. To suspend a load safely, integrate an external pilot-operated check valve or a dedicated rod lock.
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 MF32X25CM FAQ
This 32 mm bore model features a 1/4 inch air 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.
No, this specific SKU does not include the -S magnet, so CMSG, DMSG, or EMSG switches cannot be used. You would need the -S variant for sensing. The CM round-end back cover supports pivot mounting, and the fixed TPU bumpers simply decelerate the stroke end.
