Airtac MF32-40 Stainless Steel Mini Cylinder MF32X185CA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X185CA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 185mm 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 MF32X185CA
Generating 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore cylinder is built for medium-duty automation. The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown, while the two-way piston seal retains an oil film for long service life. Because the JIS-standard round body is physically shorter than a comparable ISO 6432 unit, it saves valuable mounting length in tight fixtures.
Equipped with a 1/4" port and an M10x1.25 male rod thread, the unit uses fixed TPU bumper pads to soften stroke-end impact. For practical sizing, plan for roughly 241 N of real work at 0.5 MPa, which means it can safely lift about 20.5 kg vertically with a 2:1 safety margin. This specific configuration includes a CA pivot back cover for articulating rod-end loads.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X185CA Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 402.2 N push force to deflect heavy cartons onto secondary tracks.
Pallet Stopper Arm
Deploys a 185 mm stroke stop arm in a pallet handling cell, relying on the CA pivot cover to absorb angular load variations.
Textile Loom Tensioner
Maintains fabric tension during weaving, where the SUS304 stainless barrel withstands humid operating environments.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X185CA the Right Cylinder?
When sizing this 32 mm bore, compare it directly against its neighbours: the MF25 provides 245.3 N of push at 0.5 MPa, while the larger MF40 delivers 628.3 N. If your fixture requires position holding on air loss, remember that a plain cylinder drifts when the valve is centred—the bumpers only decelerate the stroke end, so add an external rod lock or pilot check valve for secure load holding. The 185 mm stroke is well within the 500 mm standard limit, but always guide the rod end to prevent side-load bending on longer extensions.
This SKU lacks the -S magnet option, meaning it cannot accept CMSG, DMSG, or EMSG magnetic switches for position sensing. You can mount it using LB foot, FA flange, SDB pivot, or TC trunnion brackets, and the factory-installed CA rear cover provides a pivot point for angular movement.
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 MF32X185CA FAQ
This 32 mm bore double-acting cylinder uses a 1/4" port. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, 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, this specific SKU does not include the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches. The unit features fixed TPU bumper pads rather than an adjustable air cushion, and its JIS-standard riveted body is shorter than an ISO 6432 cylinder.
