Airtac MF32-40 Stainless Steel Mini Cylinder MF32X125U
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X125U is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 125mm 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 MF32X125U
Delivering 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder is built around a SUS304 stainless barrel with riveted aluminium covers that resist mild corrosion and washdown. For the same 32 mm bore and 125 mm stroke, the MF body is shorter than an ISO 6432 cylinder, saving valuable mounting length in tight fixtures. 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 the stroke-end impact.
Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches. Plan for roughly 241 N of real work at 0.5 MPa, which means it lifts about 20.5 kg vertically with a 2:1 safety margin. Air enters via a 1/4" port, driving the 12 mm rod at speeds between 30 and 800 mm/s.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X125U Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 125 mm stroke to shift parcels smoothly between adjacent belts.
Pneumatic Press Platen
Provides a steady 402.2 N downward clamping force at 0.5 MPa to hold light sheet metal housings during a spot-welding operation.
Carton Flap Folder
Drives a mechanical arm that tucks the minor flaps of corrugated shipping cartons prior to tape sealing.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X125U the Right Cylinder?
When sizing this 32 mm bore, stepping down to the MF25 yields 245.3 N of push at 0.5 MPa, whereas stepping up to the MF40 provides 628.3 N. If your process drops air pressure or centres the valve, the piston will drift because the fixed 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. This version features a U flat-end back cover and uses an M10x1.25 male rod thread. At 125 mm of travel, ensure your mounting arrangement—whether LB foot, FA flange, SDB pivot, or TC trunnion—prevents excessive side loading that could bend the rod.
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 MF32X125U FAQ
This 32 mm bore cylinder uses a 1/4" 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 force of 82 kgf at 1.0 MPa.
No, this specific SKU lacks the internal magnet required for switches. You must purchase the -S variant to use CMSG, DMSG, or EMSG sensors. The unit features a SUS304 stainless barrel and fixed TPU bumper pads rather than an adjustable air cushion.
