Airtac MSF Single Acting Mini Cylinder MSF32X80SCM
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF32X80SCM is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø32mm bore and 80mm 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 MSF Single Acting Mini Cylinder MSF32X80SCM
Delivering 323.3 N of push force at 0.5 MPa, this JIS-standard round-body mini cylinder uses a SUS304 stainless barrel and riveted aluminium covers to resist mild washdown. The MSF32X80SCM is a single-acting push type: compressed air entering the 1/4 inch port extends the Ø12 mm rod, while an internal spring retracts it. Because the spring handles the return, you only pipe and valve one port, and the cylinder fails safely to its retracted position on air loss.
The quoted output is already net of the return spring, meaning you get the full 484.1 N at 0.7 MPa without subtracting spring drag. For practical sizing, expect a safe working load of roughly 194 N, or a vertical lift of about 16.5 kg with a 2:1 margin. This 32 mm bore unit is shorter than an ISO 6432 cylinder of the same stroke, saving mounting length while using fixed TPU bumper pads for end-of-stroke deceleration.

Where the Airtac MSF Single Acting Mini Cylinder MSF32X80SCM Is Used
Part Ejection
Pushes machined components out of a fixture with 323.3 N of force at 0.5 MPa, letting the internal spring retract the rod automatically when air is cut.
Divertor Gate
Acts as a compact 32 mm bore gate mechanism that safely returns to the closed position on air loss, preventing uncontrolled product flow.
Light Lift Station
Raises lightweight trays weighing up to 16.5 kg using a 2:1 safety margin, relying on the single 1/4 inch air line for extension only.
Is the Airtac MSF Single Acting Mini Cylinder MSF32X80SCM the Right Cylinder?
When sizing this 323.3 N unit, step down to the MSF25 for 192.8 N at 0.5 MPa, or step up to the MSF40 for 535.3 N at 0.5 MPa. Choose this single-acting spring-return model for clamping, ejecting, or gating tasks that do not require a load on the return stroke. Remember the 0.2 MPa pressure floor; below this, the internal spring overcomes the air pressure and the rod will not extend. The CM round-end back cover suits tight footprints, and the -S variant provides a built-in piston magnet for CMSG, DMSG, or EMSG position sensing.
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 0.2 – 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 MSF Single Acting Mini Cylinder MSF32X80SCM FAQ
The single-acting push force is 323.3 N at 0.5 MPa and 484.1 N at 0.7 MPa. These figures are net of the return spring. The operating pressure range is 0.2 to 1.0 MPa, but you must maintain at least 0.2 MPa to overcome the internal spring and extend the rod.
No, the internal spring drives the rod to the fully retracted rest position on air loss; it cannot hold an arbitrary mid-stroke load. For a held mid-stroke load, use a double-acting MF cylinder with an external rod lock. This -S model includes a magnet for CMSG, DMSG, or EMSG switches.
