Airtac MF32-40 Stainless Steel Mini Cylinder MF32X250CA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X250CA 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 MF32X250CA
Generating 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. Because the SUS304 stainless barrel and riveted aluminium covers yield a shorter overall body than an ISO 6432 unit of the same bore and stroke, it fits neatly into tighter machine fixtures.
The construction relies on a riveted rolling-packed structure that stands up to mild washdowns, while the internal two-way seal retains an oil film for extended mechanical life. Fixed TPU bumper pads and a front-cover anti-impact pad soften the impact at stroke extremes. Since this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches. For practical sizing, plan for roughly 241 N of usable work at 0.5 MPa, which equates to lifting about 20.5 kg vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X250CA Is Used
Package Diverting Arm
Swings a 250 mm diverter lever on a packaging line using the CA pivot mount, relying on the 402.2 N push force to redirect heavy cardboard cartons at high speeds.
Lathe Tailstock Actuation
Drives a tailstock quill forward to support long bar stock, where the shorter JIS body leaves valuable room in the crowded lathe bed area.
Pallet Stop Gate
Raises and lowers a physical stop gate on a roller conveyor to hold 20 kg palletized goods, operating safely within the 241 N working load threshold.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X250CA the Right Cylinder?
When sizing this 32 mm bore, compare its 402.2 N push force at 0.5 MPa against the smaller MF25 (245.3 N) and the larger MF40 (628.3 N) to find your optimal fit. The 250 mm stroke is well within the 500 mm standard limit, but at this extension length you must carefully manage side loads to prevent rod bending. This model features a CA pivot back cover, making it ideal for clevis mounting where angular movement is required.
Without an -S suffix, this cylinder cannot support magnetic sensing. Furthermore, the fixed TPU bumpers only decelerate the piston near the end of travel; they do not function as a brake. If your process drops air pressure or the valve is centred, the rod will drift, so fit an external rod lock or a pilot-operated check valve to secure suspended loads.
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 MF32X250CA FAQ
The 32 mm bore operates on a 1/4" air port with an M10x1.25 male rod thread. At 0.5 MPa it pushes with 402.2 N and pulls with 345.6 N. At 0.7 MPa the push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
This specific SKU lacks the internal magnet, so it cannot accept CMSG, DMSG, or EMSG switches; you would need the -S variant for sensing. The CA back cover is a pivot style designed for clevis mounting, allowing the cylinder body to swing freely during articulation.
