Airtac MF32-40 Stainless Steel Mini Cylinder MF32X325SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X325SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 325mm 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 MF32X325SCM
Generating 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles substantial work within a compact footprint. The SUS304 stainless-steel barrel and riveted aluminium covers resist mild corrosion and washdown, while the piston's two-way seal retains an oil film for long service life. Because the MF body is shorter than an ISO 6432 cylinder for the same 32 mm bore and 325 mm stroke, it saves valuable mounting length in tight machinery.
Equipped with a 1/4" air port and an M10x1.25 male rod thread, the unit integrates easily into existing pneumatic setups. The built-in magnet (-S) supports CMSG, DMSG, and EMSG position switches, and the CM round-end back cover offers specific rear-pivot mounting geometry. Plan for roughly 241 N of actual work at 0.5 MPa, which means it can safely lift about 20.5 kg vertically against gravity.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X325SCM Is Used
Package Diverting
Pushes medium-weight cartons off a main conveyor belt using the 402.2 N output, with the long 325 mm stroke reaching across wider transport lanes.
Vertical Lift Gate
Raises a lightweight access panel or safety gate on a packaging machine, safely lifting loads around 20 kg while the CM round-end cover accommodates the pivot arc.
Textile Beam Indexing
Shifts a material beam laterally into a machining position, where the SUS304 stainless barrel withstands fibrous dust and occasional lint blow-off.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X325SCM the Right Cylinder?
When sizing this 32 mm bore, compare it directly with its neighbours: the MF25 yields 245.3 N at 0.5 MPa, while the MF40 provides 628.3 N. If your payload is lighter, dropping to the 25 mm bore saves space, but for heavier loads, the 40 mm is the better choice. Because this 325 mm stroke is quite long, be cautious of side loads and rod-bending moments—ensure the load is guided to prevent premature seal wear.
The fixed TPU bumper pads and front-cover anti-impact pad soften the stroke-end impact by decelerating the piston, but they do not act as an adjustable air cushion. Furthermore, a standard cylinder cannot hold its position if air pressure drops or the valve is centred; the piston will drift. For suspended or vertical loads that must remain fixed during a power loss, install an external rod lock or a pilot-operated check valve.
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 MF32X325SCM FAQ
At 0.5 MPa, the push force is 402.2 N and the pull force is 345.6 N. At 0.7 MPa, push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa. This 32 mm bore cylinder uses a 1/4" air port and an M10x1.25 male rod thread.
No, the MF is a JIS-standard round-body cylinder, not an ISO 6432 unit, though its shorter body is a packaging advantage. It features fixed TPU bumper pads that decelerate the stroke end rather than an adjustable air cushion. The -S magnet allows CMSG, DMSG, or EMSG switches for position sensing.
