Airtac MF32-40 Stainless Steel Mini Cylinder MF32X125CM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X125CM 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 MF32X125CM
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-steel barrel with riveted aluminium covers. The MF32X125CM features a 32 mm bore, a 125 mm stroke, and a 1/4" port. Because the riveted rolling-packed structure is more compact, the overall body is shorter than an ISO 6432 cylinder of the same bore and stroke, delivering a real packaging advantage in tight machinery. Inside, a heterogeneous two-way seal retains an oil film for long life, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts.
For practical sizing, plan for about 241 N of real work at 0.5 MPa, which is roughly 60 percent of the theoretical push rating. Alternatively, you can expect it to lift about 20.5 kg vertically when applying a 2:1 safety margin. The CM suffix denotes a round-end rear cover. Note that because this specific SKU lacks the -S magnet suffix, it cannot accept CMSG, DMSG, or EMSG magnetic switches.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X125CM Is Used
Package Diverting Gate
Actuates a routing flap on a 200 mm belt conveyor to sort medium-weight cartons, utilising the 402.2 N push force to overcome friction during transitions.
CNC Lathe Door Operator
Opens and closes a sliding machine tool safety door, where the compact JIS body length saves valuable mounting space along the guarding frame.
Pallet Component Pusher
Indexes cardboard blanks or lightweight aluminium extrusions into a stacking fixture prior to banding, relying on the fixed TPU pads to absorb end-of-stroke impact.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X125CM 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 application demands position holding, remember that a plain cylinder drifts when air is lost or the valve is centred; the fixed bumpers only decelerate the stroke end and act neither as a lock nor a brake. To secure a load safely, integrate an external rod lock or a pilot-operated check valve. For mounting flexibility, this unit supports LB foot, FA flange, SDB pivot, and TC trunnion brackets. At a 125 mm stroke, ensure your guiding structure handles side loads to prevent rod bending, and if you need position feedback, select the -S magnet variant instead of this non-magnetic model.
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 MF32X125CM FAQ
This 32 mm bore double-acting cylinder has a 1/4" port and an M10x1.25 male rod thread. The thrust is 402.2 N push and 345.6 N pull at 0.5 MPa, increasing to 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
This specific SKU lacks the internal magnet, so it cannot accept CMSG, DMSG, or EMSG switches; you must order the -S variant for position sensing. Furthermore, while it does not conform to ISO 6432, its JIS-standard riveted round-body design is physically shorter than an ISO 6432 cylinder of the same bore and stroke, saving mounting length.
