Airtac MF32-40 Stainless Steel Mini Cylinder MF40X175UFA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X175UFA 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 MF40X175UFA
Generating 628.3 N of push force at 0.5 MPa, this 40 mm bore double-acting mini cylinder tackles heavy-duty positioning within tight machine footprints. Because the JIS-standard round body is physically shorter than a comparable ISO 6432 unit for the same 175 mm stroke, it saves valuable mounting length. The SUS304 stainless barrel and riveted aluminium covers shrug off mild washdown while the internal two-way seal retains an oil film for long service life.
Fixed TPU bumper pads and a front-cover anti-impact pad work together to decelerate the piston at stroke ends, though they do not provide adjustable cushioning. For real-world sizing, plan for a safe working load of about 377 N (roughly 60% of the 0.5 MPa rating), which translates to lifting a 32 kg part vertically with a 2:1 safety margin. Air connects via a 1/4" port, and the male rod thread is M14x1.5.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X175UFA Is Used
Stamping Press Ejection
Uses the 628.3 N push force at 0.5 MPa to knock heavy stamped metal parts out of a die, where the shorter JIS body prevents interference with the press tooling.
Pallet Stopper Gate
Acts as a robust pneumatic stop for loaded pallets on a conveyor, relying on the FA flange to secure the cylinder against high lateral impact forces.
Carton Flap Folder
Drives heavy cardboard flaps down on an automated packing line, with the fixed TPU bumpers absorbing the repetitive end-of-stroke shocks.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X175UFA the Right Cylinder?
When sizing this 40 mm bore, dropping down to an MF32 reduces the push force to 402.2 N at 0.5 MPa, while the 40 mm bore itself is the largest available in the MF series, so exceeding its capacity requires moving to a different cylinder family entirely. The included U flat-end back cover and FA flange mounting provide straightforward rigid attachment for your fixture.
Note that a plain double-acting cylinder like this MF40X175UFA will drift if air pressure is lost or the control valve is centred; the TPU bumpers only soften the end-of-stroke impact and cannot act as a brake. To suspend a load safely mid-stroke, incorporate an external pilot-operated check valve or a dedicated rod lock. Additionally, this specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG reed switches for position sensing.
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 MF40X175UFA 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. This 40 mm bore cylinder uses a 1/4" air port and an M14x1.5 male rod thread.
No, this specific SKU does not have the -S option, so it lacks a piston magnet and cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. It features a SUS304 stainless barrel and fixed TPU bumper pads rather than an adjustable air cushion.
