Airtac MF32-40 Stainless Steel Mini Cylinder MF32X25SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X25SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 25mm 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 MF32X25SCM
Delivering 402.2 N of push force at 0.5 MPa, this 32 mm bore double-acting actuator uses a built-in magnet for position sensing. The riveted rolling-packed structure joins an SUS304 stainless steel barrel to aluminium covers, resisting mild corrosion and washdown. A two-way oil-retaining piston seal maintains a lubricating film for extended cycle life.
Because the JIS-standard round body is physically shorter than an ISO 6432 cylinder of the same bore and stroke, it fits tighter machinery layouts. Plan for a safe working load of roughly 241 N, which translates to lifting about 20.5 kg vertically with a 2:1 safety margin. Fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impact, while the 1/4 inch port handles the air supply.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X25SCM Is Used
Package Diverter Gate
Snaps a sorting flap into place on a packaging line, using the 25 mm stroke to reroute cartons rapidly without occupying excessive frame depth.
Clamp Station
Secures an aluminium housing during a CNC drilling operation, applying steady clamping pressure via the 1/4 inch port and 32 mm bore.
Pallet Stopper Pin
Deploys a short mechanical stop to halt pallets at an assembly station, relying on the CM round-end rear cover for pivot articulation.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X25SCM the Right Cylinder?
When sizing this 32 mm bore, the adjacent MF25 provides 245.3 N at 0.5 MPa for lighter jobs, while the larger MF40 offers 628.3 N for heavier pushing. This model includes the -S magnet for CMSG, DMSG, or EMSG switches, and features a CM round-end back cover suitable for clevis mounting.
Remember that a standard cylinder drifts if air pressure drops or the valve is centred; the bumper pads only decelerate the stroke end and will not lock the load. For vertical or suspended loads, install an external rod lock or a pilot-operated check valve. The 25 mm stroke minimizes rod bending, but ensure side loads remain minimal.
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 MF32X25SCM FAQ
At 0.5 MPa it pushes with 402.2 N and pulls with 345.6 N. At 0.7 MPa the push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa. The air port is 1/4 inch.
No, this model uses fixed TPU bumper pads to decelerate the stroke end rather than an adjustable air cushion. If your application requires variable cushioning for high speeds, consider the MFC variant. The -S magnet allows CMSG, DMSG, and EMSG sensors.
