Airtac MF32-40 Stainless Steel Mini Cylinder MF32X45SU
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X45SU is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 45mm 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 MF32X45SU
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MF32X45SU is a JIS-standard round-body mini cylinder engineered for tight machinery layouts. Its SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown, while the riveted rolling-packed structure keeps the overall body shorter than a comparable ISO 6432 unit for the same 32 mm bore and 45 mm stroke. The 1/4 inch port and M10x1.25 male rod thread accommodate robust airflow and mounting.
The piston relies on a heterogeneous two-way seal that retains an oil film for extended lifespan, and fixed TPU bumper pads combined with a front-cover anti-impact pad soften stroke-end impacts. Because this SKU includes the -S magnet, it supports CMSG, DMSG, and EMSG position switches. Plan for roughly 241 N of actual work at 0.5 MPa, which translates to lifting about 20.5 kg vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X45SU Is Used
Clamp Actuation
Securing aluminium extrusions in a machining fixture using the 402.2 N push force to hold parts firmly during milling operations.
Carton Flap Folding
Folding corrugated cardboard flaps on a packaging line where the short 45 mm stroke and compact JIS body fit between conveyor belts.
Parts Diverting
Pushing small metal components down a gravity chute using the integrated magnet and a DMSG switch to confirm diversion.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X45SU the Right Cylinder?
When sizing this 32 mm bore, compare it directly with its neighbours: the MF25 provides 245.3 N of push at 0.5 MPa, while the MF40 steps up to 628.3 N. Choose the MF32X45SU when your load requires moderate force in a compact footprint. The flat-end U back cover suits direct rear mounting, and you can utilise LB foot, FA flange, SDB pivot, or TC trunnion brackets as needed.
Remember that a standard double-acting cylinder drifts if air pressure drops or the valve centres; the TPU bumpers only decelerate the stroke end and will not act as a brake. To suspend a load safely, install an external rod lock or a pilot-operated check valve. Additionally, the 45 mm stroke is well within standard limits, but always guide the rod to prevent side-load bending.
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 MF32X45SU FAQ
This 32 mm bore cylinder features a 1/4 inch port and generates 402.2 N push and 345.6 N pull at 0.5 MPa. At 0.7 MPa, it provides 563 N push and 483.8 N pull. The theoretical maximum force is 82 kgf at 1.0 MPa.
It uses a SUS304 stainless barrel with riveted aluminium covers, making the body shorter than an ISO 6432 cylinder. This specific configuration includes a flat-end U back cover and a built-in magnet for CMSG, DMSG, or EMSG sensors.
