Airtac MF32-40 Stainless Steel Mini Cylinder MF32X300SU
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X300SU is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 300mm 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 MF32X300SU
Generating 402.2 N of push force at 0.5 MPa, the AirTAC MF32X300SU is a JIS-standard round-body mini cylinder engineered for tight machinery layouts. For the same 32 mm bore and 300 mm stroke, this unit occupies a shorter overall length than an ISO 6432 cylinder, delivering a tangible packaging advantage. The SUS304 stainless-steel barrel and riveted aluminium covers resist mild corrosion and washdown environments.
This double-acting actuator features a 1/4" port and a U flat-end back cover. It relies on fixed TPU bumper pads to decelerate the stroke end, while the piston's two-way seal retains an oil film for long service life. Plan for a safe working load of roughly 241 N (about 60% of the 0.5 MPa rating), which translates to lifting a 20.5 kg part vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X300SU Is Used
Carton Diverting
Pushes corrugated cartons onto secondary packaging lines using 402.2 N of thrust at 0.5 MPa, with the U flat-end cover mounting flush against the conveyor frame.
Pouch Sealing Press
Maintains consistent downward pressure on flexible packaging jaws over a 300 mm stroke, relying on the SUS304 stainless barrel to withstand daily washdowns.
Tiered Tray Indexing
Advances stacked plastic trays in sorting machines, safely moving loads around 20.5 kg vertically while the -S magnet triggers DMSG position sensors.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X300SU the Right Cylinder?
When sizing this 32 mm bore, the smaller MF25 provides 245.3 N at 0.5 MPa, whereas stepping up to the MF40 yields 628.3 N. Because this SKU includes the -S magnet, it is fully compatible with CMSG, DMSG, and EMSG reed or electronic switches. The U flat-end rear cover suits direct mounting, and you can utilize LB foot, FA flange, SDB pivot, or TC trunnion brackets.
With a 300 mm stroke, minimize side loads to prevent rod bending and premature seal wear. Note that cutting air supply causes the piston to drift; the bumpers only soften end impacts and will not lock the load. Use an external rod lock or pilot-operated check valve if you need strict position holding.
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 MF32X300SU FAQ
This double-acting 32 mm bore cylinder features a 1/4" 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.
It is a JIS-standard round-body cylinder with a SUS304 stainless barrel and riveted aluminium covers. For the same 32 mm bore and 300 mm stroke, the MF body is physically shorter than an ISO 6432 cylinder, saving mounting length. It uses fixed TPU bumper pads to decelerate, not an adjustable air cushion.
