Airtac MF32-40 Stainless Steel Mini Cylinder MF32X175SU
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X175SU is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 175mm 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 MF32X175SU
Delivering 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder integrates a SUS304 stainless barrel with riveted aluminium covers to resist mild corrosion and washdown. Because the MF body is physically shorter than an ISO 6432 cylinder for the same 32 mm bore and 175 mm stroke, it saves valuable mounting length in tight fixtures. The piston relies on a two-way oil-retaining seal for long life, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impact. This SKU includes the -S magnet for position sensing and features a U flat-end back cover.
Air extends and retracts the rod through a 1/4" port, with a male M10x1.25 rod thread. For practical actuation at 0.5 MPa, plan for roughly 241 N of real work, which translates to lifting about 20.5 kg vertically with a 2:1 safety margin. The bumper pads decelerate the stroke end but do not act as an adjustable air cushion; for variable cushioning at high speeds, consider the MFC variant.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X175SU Is Used
Package Diverting
Pushes lightweight cardboard cartons on a packaging line using the 402.2 N push force, with the U flat-end cover mounted flush to the conveyor frame.
Clamp Actuation
Secures aluminium extrusions during machining operations, where the 175 mm stroke provides ample reach to clear the workpiece before clamping.
Vertical Lift Gate
Raises a small access gate weighing up to 20.5 kg, relying on the -S magnet and DMSG sensor to confirm the fully open position.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X175SU the Right Cylinder?
When sizing this 32 mm bore, the smaller MF25 provides 245.3 N at 0.5 MPa, whereas the larger MF40 offers 628.3 N at 0.5 MPa. This 175 mm stroke sits well within the 500 mm standard limit, though at this length you should verify side-loading to prevent rod bending. The included -S magnet allows direct mounting of CMSG, DMSG, or EMSG reed and electronic switches. The U flat-end rear cover suits direct rear mounting applications.
Remember that a standard cylinder drifts when air is lost or the valve is centred, as the fixed bumpers only soften the end of travel rather than locking the load. To maintain vertical position holding, incorporate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 MF32X175SU FAQ
The 32 mm bore features a 1/4" port and a 12 mm rod with an M10x1.25 male 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.
Built to JIS standards, the SUS304 stainless round body is shorter than an equivalent ISO 6432 cylinder, saving mounting length. It uses fixed TPU bumper pads to decelerate the stroke end rather than an adjustable air cushion, and the included -S magnet supports CMSG, DMSG, or EMSG sensors.
