Airtac MF32-40 Stainless Steel Mini Cylinder MF32X250SCMTC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X250SCMTC is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 250mm 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 MF32X250SCMTC
Generating 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore AirTAC mini cylinder handles demanding 250 mm stroke tasks. Because it follows a JIS-standard round-body format, the overall length is noticeably shorter than a comparable ISO 6432 unit, yielding a real packaging advantage in tight machine cells. The SUS304 stainless steel barrel and riveted aluminium covers naturally resist mild corrosion and washdown, while the internal two-way seal retains an oil film for extended mechanical life.
Equipped with a built-in piston magnet (-S), the unit supports CMSG, DMSG, and EMSG position sensing. It carries fixed TPU bumper pads and a front-cover anti-impact pad to soften stroke-end impact, though these merely decelerate the piston rather than acting as an adjustable cushion. For practical actuation at 0.5 MPa, plan for a safe working load of roughly 241 N. Alternatively, you can expect it to lift about 20.5 kg vertically when applying a 2:1 safety margin to the 0.5 MPa output.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X250SCMTC Is Used
Package Diverter Gate
Actuates a routing flap on a 250 mm stroke to redirect parcels weighing up to 20 kg on a packaging line, capitalising on the 402.2 N push force at 0.5 MPa.
Vertical Carton Lift
Raises corrugated cartons between conveyor tiers, safely lifting roughly 20.5 kg loads thanks to the 32 mm bore output paired with a 2:1 safety margin.
Textile Loom Tensioner
Shifts a yarn tensioning bar through the 250 mm travel, using the TC trunnion mount to accommodate angular movement while the SUS304 barrel resists humid conditions.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X250SCMTC the Right Cylinder?
When sizing this 32 mm bore actuator, stepping down to the MF25 yields 245.3 N of push at 0.5 MPa, whereas moving up to the MF40 provides 628.3 N. This model includes a TC trunnion mount and a CM round-end back cover, offering versatile pivot integration. The 1/4" port and M10x1.25 male rod thread match the bore specification exactly. Across the 250 mm stroke, be mindful of side-loading and rod-bending moments to prevent premature seal wear.
Note that a standard double-acting cylinder drifts if air pressure drops or the valve is centred; the bumpers only soften the end-of-stroke impact and do not function as a braking mechanism. To suspend a load safely during an air loss event, incorporate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 MF32X250SCMTC FAQ
This 32 mm bore double-acting cylinder features a 1/4" air port and an M10x1.25 male rod thread. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, increasing to 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
Yes to the sensor; the -S suffix indicates a built-in magnet for CMSG, DMSG, or EMSG switches. Regarding the cushion, this unit relies on fixed TPU bumper pads to decelerate the stroke end, not an adjustable air cushion. For adjustable cushioning, consider the MFC variant. The JIS-standard round-body design is also physically shorter than an ISO 6432 cylinder of the same bore and stroke.
