Airtac MF32-40 Stainless Steel Mini Cylinder MF40X175SCA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X175SCA 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 MF40X175SCA
Delivering 628.3 N of push force at 0.5 MPa, this 40 mm bore double-acting JIS-standard round-body mini cylinder handles heavy-duty automation tasks. The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown, while the piston's two-way oil-retaining seal ensures long service life. Because the MF body is shorter than an ISO 6432 cylinder for the same 175 mm stroke, it saves valuable mounting length in tight fixtures.
The integrated -S piston magnet allows direct mounting of CMSG, DMSG, or EMSG switches for position sensing. Fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impact without the adjustment of an air cushion. Plan for a safe working load of roughly 377 N (about 60% of the 0.5 MPa rating), which means it can reliably lift a 32 kg vertical load with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X175SCA Is Used
Stamping Press Feed
Pushes heavy metal blanks into a stamping die, utilizing the 628.3 N push force to overcome insertion friction in a compact sub-assembly.
Pallet Diverting
Extends 175 mm to route loaded pallets on a packaging line, with the CA pivot accommodating the lateral arc of the diverting arm.
Vertical Gate Lifting
Raises a 30 kg access gate on an automated machine guard, operating comfortably within the 32 kg safe vertical lift capacity.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X175SCA the Right Cylinder?
When sizing this 40 mm bore unit, compare its 628.3 N push force at 0.5 MPa against the smaller MF32, which provides 402.2 N. Since 40 mm is the largest available MF bore, moving beyond this capacity requires a different cylinder family entirely. The 1/4" port and M14x1.5 male rod thread are fixed to this bore size.
This specific SKU includes a CA rear pivot cover for clevis mounting and an -S magnet for sensors. Note that a standard cylinder drifts if air pressure drops or the valve is centred; the TPU bumpers only decelerate the stroke end and do not act as a brake. To suspend a load safely, install an external rod lock or a pilot-operated check valve. For a 175 mm stroke, ensure the load is guided to prevent rod bending and premature seal wear.
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 MF40X175SCA FAQ
At 0.5 MPa it provides 628.3 N push and 527.8 N pull. At 0.7 MPa it provides 879.6 N push and 738.9 N pull. The theoretical maximum force is 128.1 kgf at 1.0 MPa. The air port size is 1/4".
No, the MF is a JIS-standard round-body cylinder that is physically shorter than an ISO 6432 unit, so ISO brackets will not fit. Cushioning is provided by fixed TPU bumper pads that decelerate the stroke end; it is not an adjustable air cushion. The -S magnet supports CMSG, DMSG, and EMSG sensors.
