Airtac MF32-40 Stainless Steel Mini Cylinder MF32X350SCMFA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X350SCMFA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 350mm 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 MF32X350SCMFA
Delivering 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. For the same 32 mm bore and 350 mm stroke, the SUS304 stainless steel barrel and riveted aluminium covers create a body notably shorter than an ISO 6432 unit, saving valuable mounting length. The piston relies on a heterogeneous two-way seal that retains an oil film for long service life, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts.
Equipped with a built-in magnet for CMSG, DMSG, or EMSG switches, this configuration includes a CM round-end back cover and an FA flange mounting accessory. The 1/4" port and M10x1.25 male rod thread support robust airflow and linkage. Planning for about 241 N of actual work at 0.5 MPa leaves a safe operational margin, and the rod can vertically lift approximately 20.5 kg with a 2:1 safety factor.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X350SCMFA Is Used
Carton Diverting Gate
Pushes lightweight cardboard cartons across a packaging line, using the 350 mm stroke to clear the conveyor belt width efficiently.
Clamp Actuation
Extends a secondary hold-down clamp on an CNC milling fixture, applying firm 0.5 MPa pressure without deforming the aluminium workpiece.
Vertical Parts Lift
Raises small steel brackets between processing tiers, safely handling loads up to 20.5 kg thanks to the 32 mm bore thrust class.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X350SCMFA the Right Cylinder?
When sizing this 32 mm bore actuator, the smaller MF25 provides 245.3 N at 0.5 MPa, whereas stepping up to the MF40 yields 628.3 N. This model hits a strong middle ground for 350 mm travel. Because the base MF uses fixed TPU bumpers rather than an adjustable air cushion, verify your moving mass can be safely decelerated across that distance; for high-speed cycling, consider the MFC variable-cushion variant.
The included FA flange and CM round-end rear cover suit direct pivot or fixed bracket installations. Remember that a standard double-acting cylinder drifts when air is removed or the valve centres—the bumpers only soften the end of stroke, they do not lock the piston. To suspend a vertical load safely, fit 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 MF32X350SCMFA FAQ
This 32 mm bore double-acting cylinder features a 1/4" 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, with a theoretical maximum force of 82 kgf at 1.0 MPa.
The MF is a JIS-standard round-body cylinder, not an ISO 6432 unit, though its riveted stainless-steel body is intentionally shorter than an ISO 6432 equivalent to save space. This SKU includes the -S magnet for CMSG, DMSG, or EMSG switches, and uses an FA flange with a CM round-end cover for installation.
