Airtac MF32-40 Stainless Steel Mini Cylinder MF32X120CA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X120CA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 120mm 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 MF32X120CA
Delivering 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder integrates a SUS304 stainless-steel barrel with riveted aluminium covers to resist mild corrosion and washdown. The piston relies on a heterogeneous two-way seal that retains an oil film for long service life, while a fixed anti-impact pad on the front cover protects the internals. Because this MF32X120CA configuration lacks the -S suffix, it cannot accept CMSG, DMSG, or EMSG magnetic switches.
For the same 32 mm bore and 120 mm stroke, the MF body is physically shorter than an ISO 6432 cylinder, delivering a real packaging advantage in tight fixtures. The 1/4" port feeds the chamber efficiently, and fixed TPU bumper pads at both ends absorb the stroke-end impact. Plan for roughly 241 N of actual work at 0.5 MPa, which translates to lifting about 20.5 kg vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X120CA Is Used
Pallet Diverting Gate
Uses the 402.2 N push force at 0.5 MPa to swing a diverter arm on a packaging line, routing boxes down secondary lanes without stalling.
CNC Lathe Door Actuator
Leverages the compact JIS body length to fit within a tight machine enclosure, sliding the safety interlock door open and closed across 120 mm.
Tote Stacking Pusher
Employs the CA pivot mount to articulate a pusher plate, lifting and stacking rigid totes weighing up to 20.5 kg with a safe 2:1 margin.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X120CA the Right Cylinder?
When sizing this 32 mm bore, the smaller MF25 provides 245.3 N of push force at 0.5 MPa, while the larger MF40 steps up to 628.3 N at the same pressure, giving you clear boundaries for your force requirements. The 120 mm stroke is well within the 500 mm standard maximum, keeping the unit readily available without special ordering.
This specific SKU features a CA pivot back cover for articulated mounting, but because it has no internal magnet, position sensing is impossible without upgrading to an -S variant. Furthermore, standard double-acting cylinders drift when air is removed or a valve is centred; the bumpers only decelerate the stroke end and will not lock the load, so integrate an external rod lock or pilot check valve if you need to hold a vertical position.
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 MF32X120CA FAQ
This 32 mm bore 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.
No, because this model lacks the -S suffix, it has no internal magnet and cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing, though both versions share the same shorter-than-ISO-6432 JIS body and fixed TPU bumper pads.
