Airtac MF32-40 Stainless Steel Mini Cylinder MF32X40SCMTC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X40SCMTC is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 40mm 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 MF32X40SCMTC
Generating 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder integrates a SUS304 stainless barrel with riveted aluminium covers to resist mild washdown. The shorter overall body length compared to an equivalent ISO 6432 unit provides a tangible packaging advantage in tight machinery. A built-in piston magnet (-S) enables direct mounting of CMSG, DMSG, or EMSG sensors for position confirmation.
The 32 mm bore uses a 1/4" port and an M10x1.25 male rod thread to cycle at 30-800 mm/s. Fixed TPU bumper pads and a front-cover anti-impact pad absorb stroke-end shock without adjustable cushioning. For practical actuation at 0.5 MPa, plan for roughly 241 N of usable working force, which equates to lifting about 20.5 kg vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X40SCMTC Is Used
Package Diverter Gate
Swings a sorting flap on a packaging line using the 402.2 N push force, with the TC trunnion absorbing pivot stress during high-speed parcel routing.
Small Press Ejection
Kicks stamped metal parts out of a die using the 40 mm stroke, relying on the built-in magnet and EMSG sensor to confirm the ejection completed.
Carton Flap Folder
Folds corrugated box flaps prior to tape sealing, where the compact JIS body saves valuable mounting length on a narrow side-belt conveyor frame.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X40SCMTC the Right Cylinder?
When sizing this 32 mm bore, the smaller MF25 yields 245.3 N at 0.5 MPa while the larger MF40 provides 628.3 N, letting you step up or down to match the exact load. The included TC trunnion mount pairs with the CM round-end back cover to handle pivoting loads smoothly. Because this is a short 40 mm stroke, side-load stress on the rod remains minimal, but ensure the mounting geometry absorbs lateral forces.
Remember that standard double-acting cylinders drift when air pressure drops or the directional valve centres; the internal bumpers only soften the end-of-stroke impact and do not function as a braking mechanism. To suspend a load safely mid-stroke, install an external pilot-operated check valve or a dedicated rod lock.
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 MF32X40SCMTC FAQ
This 32 mm bore cylinder features a 1/4" air port and delivers 402.2 N push / 345.6 N pull at 0.5 MPa, 563 N push / 483.8 N pull at 0.7 MPa, with a theoretical maximum of 82 kgf at 1.0 MPa.
No, the base MF uses fixed TPU bumper pads for end-of-stroke deceleration rather than adjustable air cushions, and it does not conform to ISO 6432, though its JIS round-body design is intentionally shorter than ISO 6432 to save space.
