Airtac MF32-40 Stainless Steel Mini Cylinder MF32X300CM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X300CM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 300mm 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 MF32X300CM
Delivering 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles demanding 300 mm strokes with a compact footprint. Because the SUS304 stainless barrel and riveted aluminium covers yield a shorter overall body than an equivalent ISO 6432 unit, you save valuable mounting length in tight machinery. The 1/4 inch port and M10x1.25 male rod thread provide robust pneumatic and mechanical interfaces for this 32 mm bore class.
The construction pairs fixed TPU bumper pads with a front-cover anti-impact pad to soften stroke-end impacts, though these merely decelerate the piston rather than acting as an adjustable air cushion. A heterogeneous two-way seal retains an oil film for extended mechanical life. For practical sizing, plan for a safe working load of roughly 241 N, which translates to lifting about 20.5 kg vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X300CM Is Used
Package Diverting
Pushes parcels across sorting lanes using the 402.2 N output, while the 300 mm stroke reaches across a 24 inch conveyor belt.
Pallet Strapping
Extends to hold a strapping head away from the pallet stack during the tensioning cycle, relying on the compact body to fit narrow gantries.
Textile Beam Shifting
Transfers heavy warp beams between processing stations, utilizing the 1/4 inch port for rapid rod extension and retraction.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X300CM the Right Cylinder?
When sizing this 32 mm bore, the smaller MF25 yields 245.3 N at 0.5 MPa, while the larger MF40 provides 628.3 N, allowing you to step up or down based on your exact force needs. The CM round-end back cover suits rear pivot mounting, and you can adapt the body using LB foot, FA flange, SDB pivot, or TC trunnion brackets. Because this 300 mm stroke is relatively long, ensure your front mounting suppresses rod side-loading to prevent premature seal wear and rod bending.
This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG reed switches; choose the -S variant if your application requires position sensing. Furthermore, a standard cylinder drifts when air is lost or the valve is centred, as the bumpers only soften the end of travel rather than locking the rod. To suspend a load safely during an air failure, integrate an external rod lock or a pilot-operated check valve into your 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 MF32X300CM FAQ
At 0.5 MPa this 32 mm bore cylinder pushes with 402.2 N and pulls with 345.6 N. At 0.7 MPa the push is 563 N and the pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa, and the air port size is 1/4 inch.
This specific SKU lacks the internal magnet, so CMSG, DMSG, or EMSG switches cannot be used; you need the -S variant for sensing. Regarding dimensions, the JIS-standard riveted SUS304 stainless body is explicitly shorter than an ISO 6432 cylinder for the same 32 mm bore and 300 mm stroke, saving mounting length.
