Airtac MF32-40 Stainless Steel Mini Cylinder MF40X95SU
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X95SU is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 95mm 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 MF40X95SU
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy-duty tasks within tight machinery envelopes. For the same 40 mm bore and 95 mm stroke, the MF body is notably shorter than an ISO 6432 cylinder, providing a tangible packaging advantage. The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments, while the piston's two-way seal retains an oil film for extended operational life.
Equipped with a 1/4" port and an M14x1.5 male rod thread, the unit features fixed TPU bumper pads and a front-cover anti-impact pad that decelerate the stroke end without offering adjustable cushioning. Because it carries the -S suffix, a built-in piston magnet enables CMSG, DMSG, or EMSG switches for position sensing. Plan for roughly 377 N of actual work at 0.5 MPa, which means it can comfortably lift about 32 kg vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X95SU Is Used
Package Diverting Arm
Pushes heavy cartons off a main packaging line using its 628.3 N thrust, with the U flat-end rear cover bolted directly to the conveyor frame.
Press Fit Station
Seats bearings into metal housings on an assembly line, relying on the fixed TPU bumper pads to soften the 95 mm downward stroke impact.
Pallet Stopper Gate
Acts as a heavy-duty pneumatic stop for inbound pallets, where the SUS304 stainless barrel withstands dusty industrial environments.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X95SU the Right Cylinder?
When sizing this 40 mm bore, consider the adjacent MF32 which provides 402.2 N of push at 0.5 MPa if your load is lighter, as there is no larger standard MF bore available for higher force demands. The U flat-end back cover on this specific SKU suits direct rear mounting against a flat plate. For position feedback, the internal magnet pairs directly with CMSG, DMSG, or EMSG sensors.
Remember that a standard double-acting cylinder drifts if air pressure drops or the valve is centred; the TPU bumpers only soften the end-of-stroke impact and do not function as a braking mechanism. To suspend a load safely during an air loss event, integrate an external rod lock or a pilot-operated check valve into your circuit. At a 95 mm stroke, side loading is minimal, but always ensure the load axis aligns with the 16 mm rod to prevent 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 MF40X95SU 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, the push is 879.6 N and the 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, the MF is a JIS-standard round-body cylinder, not an ISO 6432 compliant unit. However, for the same 40 mm bore and 95 mm stroke, the MF body is physically shorter than an ISO 6432 cylinder, which saves mounting length. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG switches.
