Airtac MF32-40 Stainless Steel Mini Cylinder MF40X175SU
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X175SU 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 MF40X175SU
Delivering 628.3 N of push force at 0.5 MPa, the AirTAC MF40X175SU is a robust double-acting JIS-standard round-body mini cylinder built for demanding actuation. Because its riveted rolling-packed structure is physically shorter than a comparable ISO 6432 unit of the same bore and stroke, it saves valuable mounting length in tight machinery. The SUS304 stainless steel barrel pairs with aluminium covers to resist mild corrosion and washdown environments.
This 40 mm bore unit features a 1/4" port and relies on a two-way oil-retaining piston seal for prolonged operational life. For practical sizing, plan for roughly 377 N of actual work at 0.5 MPa, which safely lifts about 32 kg vertically with a 2:1 margin. Fixed TPU bumper pads and a front-cover anti-impact pad soften the stroke-end impact, decelerating the load without adjustable cushioning. Since this SKU includes the -S magnet, it is fully ready for CMSG, DMSG, or EMSG position sensing.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X175SU Is Used
Pallet Diverting Gate
Uses the 628.3 N push force to reliably pivot heavy routing gates on a packaging conveyor, shifting loaded pallets without bouncing.
Press Pad Actuation
Drives a 175 mm stroke to lower a compacting head in a recycling baler, relying on the U flat-end rear cover for a rigid frame mount.
Vertical Parts Lift
Elevates 32 kg tote bins between conveyor tiers, taking advantage of the built-in -S magnet to trigger DMSG descent sensors.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X175SU the Right Cylinder?
When sizing this actuator, note that stepping down to the MF32 bore drops the 0.5 MPa push force to 402.2 N, while the MF40 represents the largest available option in this series with a 128.1 kgf theoretical maximum at 1.0 MPa. The 175 mm stroke is well within the 500 mm standard limit, but at this length you should carefully manage side loads to prevent rod bending and premature seal wear. The rear U flat-end cover provides a straightforward mounting interface for fixed installations.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centred, as the bumpers only soften the end of travel rather than locking the piston. If your application requires strict position holding on a vertical load, incorporate an external pilot-operated check valve or a dedicated rod lock. This specific SKU includes the -S magnet for electronic or reed switches, whereas a plain MF40 model cannot accept sensors.
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 MF40X175SU FAQ
This 40 mm bore cylinder features a 1/4" port and an M14x1.5 male rod thread. At 0.5 MPa it provides 628.3 N of push force and 527.8 N of pull force. At 0.7 MPa the push increases to 879.6 N and pull to 738.9 N, with a theoretical maximum force of 128.1 kgf at 1.0 MPa.
The MF body is shorter than an ISO 6432 cylinder of the identical bore and stroke, offering a packaging advantage in tight fixtures. It uses fixed TPU bumper pads to decelerate the stroke end rather than an adjustable air cushion, and the SUS304 stainless barrel provides excellent mild corrosion resistance for washdown settings.
