Airtac MF32-40 Stainless Steel Mini Cylinder MF32X25UTC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X25UTC 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 MF32X25UTC
Generating 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles robust actuation in tight spaces. It features a SUS304 stainless-steel barrel with riveted aluminium covers. For the same 32 mm bore and 25 mm stroke, the MF body is shorter than an ISO 6432 cylinder, saving valuable mounting length.
The piston relies on a heterogeneous two-way seal that retains an oil film for long life, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts. Plan for roughly 241 N of actual work at 0.5 MPa, or lifting about 20.5 kg vertically with a 2:1 safety margin. Air connects via a 1/4 inch port.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X25UTC Is Used
Clamp Actuation
Drives short-stroke clamping arms on machining fixtures, delivering 402.2 N of push force to hold aluminium housings securely during milling.
Carton Flap Folding
Folds corrugated carton flaps on automated packaging lines where the compact JIS body saves mounting length along the conveyor frame.
Part Ejection
Ejects moulded plastic parts from press dies, using the fixed TPU bumper pads to absorb the impact at the end of the 25 mm stroke.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X25UTC the Right Cylinder?
If 245.3 N from the MF25 is insufficient and you need the next size up, this 32 mm bore provides 402.2 N at 0.5 MPa; stepping further to the MF40 yields 628.3 N. This SKU includes a U flat-end back cover and uses a TC trunnion mount. Because it lacks the -S suffix, it cannot accept CMSG, DMSG, or EMSG magnetic switches.
A plain cylinder drifts when air is lost or the valve is centred, as the bumpers only decelerate the end of travel rather than locking the rod. To suspend a load securely, install an external rod lock or a pilot-operated check valve. The short 25 mm stroke keeps rod bending minimal, but side loads should still be minimized.
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 MF32X25UTC FAQ
This 32 mm bore cylinder has a 1/4 inch 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, because this specific SKU lacks the -S suffix, it has no internal magnet and cannot accept CMSG, DMSG, or EMSG switches. The -S variant is required for position sensing.
