Airtac MF32-40 Stainless Steel Mini Cylinder MF32X110SU
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X110SU is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 110mm 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 MF32X110SU
Delivering 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder integrates a SUS304 stainless steel barrel with riveted aluminium covers to resist mild corrosion and washdown. Because the MF body is shorter than an ISO 6432 cylinder for the same 32 mm bore and 110 mm stroke, it saves valuable mounting length in tight fixtures. The piston relies on a two-way oil-retaining seal for long life, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts.
Equipped with a built-in magnet (-S) for CMSG, DMSG or EMSG switches, this unit features a flat-end U back cover and a 1/4 inch port. Plan for about 241 N of actual work at 0.5 MPa, which means it lifts about 20.5 kg vertically with a 2:1 safety margin. The Ø12 mm rod extends and retracts at 30-800 mm/s, giving you robust actuation without adjustable air cushioning.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X110SU Is Used
Package Diverting
Pushes medium-weight cartons off a sorting line using 402.2 N of thrust, fitting neatly into tight transfer gaps.
Pallet Stopper
Acts as a flat-end U rear stop for pallets entering a wrapping station, absorbing impact with fixed TPU pads.
Clamp Actuation
Secures aluminium extrusions during a sawing operation, lifting parts up to 20.5 kg safely with a 2:1 margin.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X110SU the Right Cylinder?
When sizing this 32 mm bore, stepping down to the MF25 yields 245.3 N at 0.5 MPa, whereas moving up to the MF40 provides 628.3 N. This model hits a solid middle ground for medium-force tasks. If your process drops air pressure or centres the valve, the piston will drift, as the fixed bumpers only decelerate the end of travel rather than locking the load. To hold a suspended weight securely, add an external rod lock or a pilot-operated check valve.
The flat-end U rear cover suits direct mounting, and you can pair the -S magnet with reed or electronic sensors for position confirmation. With a 110 mm stroke, ensure your guiding structure minimizes side-load to prevent rod bending over the extension length.
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 MF32X110SU FAQ
This 32 mm bore cylinder features a 1/4 inch port and an M10x1.25 male rod thread. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum of 82 kgf at 1.0 MPa.
No, the MF is a JIS-standard round-body cylinder, not an ISO 6432 compliant unit. However, for the same 32 mm bore and 110 mm stroke, the riveted SUS304 stainless MF body is physically shorter than an ISO 6432 cylinder, saving mounting length. It uses fixed TPU bumper pads rather than an adjustable cushion.
