Airtac MF32-40 Stainless Steel Mini Cylinder MF40X175CA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X175CA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm 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 MF40X175CA
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy-duty positioning tasks. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown, while the piston's two-way seal retains an oil film for extended mechanical life. Because the MF body is shorter than an ISO 6432 cylinder for the same 40 mm bore and 175 mm stroke, it saves valuable mounting length in tight machinery.
Equipped with fixed TPU bumper pads and a front-cover anti-impact pad, the stroke end is reliably decelerated without the need for adjustable cushioning. For practical sizing, plan for about 377 N of real work at 0.5 MPa, which translates to safely lifting a 32 kg part vertically with a 2:1 margin. This specific SKU lacks a magnet and cannot host a CMSG, DMSG or EMSG sensor; the -S variant is required for position detection.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X175CA Is Used
Stamping Press Ejection
Uses the 628.3 N push force at 0.5 MPa to knock heavy stamped metal panels out of a die, relying on the CA pivot to accommodate angular rod movement.
Bulk Container Flap Sealing
Swings heavy cardboard container flaps closed on a high-speed packaging line, where the compact JIS body saves critical machine length.
Pallet Divertor Arm
Actuates a heavy diverter gate on a conveyor to route loaded pallets, benefiting from the SUS304 barrel in mildly humid warehouse environments.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X175CA the Right Cylinder?
When sizing this 40 mm bore unit, step down to the MF32 if your task only requires 402.2 N of push force at 0.5 MPa, as the 40 mm bore is the largest available in the MF series. The 1/4" port and M14x1.5 male rod thread provide robust airflow and mounting for this force class. The integrated CA pivot back cover is ideal for articulating loads, and you can pair it with LB foot, FA flange or TC trunnion brackets.
Note that a standard MF cylinder drifts when air is lost or the directional valve is centred; the TPU bumpers only soften the end of stroke and do not function as a locking brake. To suspend a load safely, install an external rod lock or a pilot-operated check valve. Additionally, the 175 mm stroke demands careful alignment to prevent rod-bending side loads.
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 MF40X175CA FAQ
The 40 mm bore provides a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa. At 0.7 MPa, push is 879.6 N and pull is 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa. This model uses a 1/4" air port and an M14x1.5 male rod thread.
No, this specific SKU does not include a piston magnet, so it cannot accept CMSG, DMSG or EMSG magnetic switches. You would need the MF40X175CA-S variant for sensing. The unit features a CA pivot back cover and fixed TPU bumper pads that decelerate the stroke end, but it is not equipped with an adjustable air cushion.
