Airtac MSF Single Acting Mini Cylinder MSF32X80CM
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF32X80CM 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 MSF32X80CM
Delivering 323.3 N of push force at 0.5 MPa, this 32 mm bore AirTAC mini cylinder uses compressed air to extend the rod and an internal spring to retract it. Because it is single-acting, you only need to plumb one 1/4" port, simplifying valve requirements and ensuring the rod fails to the retracted position on air loss. The riveted SUS304 stainless barrel and aluminium covers form a JIS-standard round body that is notably shorter than a comparable ISO 6432 unit, saving valuable mounting length.
The quoted push force is already net of the return spring, which requires a minimum 0.2 MPa operating pressure to overcome. For practical sizing, this translates to a safe working load of roughly 194 N, or a vertical lift capacity of about 16.5 kg with a 2:1 safety margin. This specific CM round-end configuration lacks the -S magnet option, so it cannot accept CMSG, DMSG, or EMSG position sensors.

Where the Airtac MSF Single Acting Mini Cylinder MSF32X80CM Is Used
Part Ejection
Uses the 323.3 N push stroke to positively eject stamped parts from a die, relying on the spring to withdraw the rod clear of the tooling between cycles.
Divertor Gate
Powers a sorting flap on a conveyor line; air pressure swings the gate out, and the internal spring pulls it back to allow straight-through product flow.
Vertical Lift Stop
Raises a lightweight physical stop to catch items on a gravity roller track, safely holding loads up to about 16.5 kg before retracting to release them.
Is the Airtac MSF Single Acting Mini Cylinder MSF32X80CM the Right Cylinder?
When sizing this 32 mm bore, compare its 323.3 N @0.5 MPa output against the adjacent options: step down to an MSF25 for 192.8 N, or up to an MSF40 for 535.3 N. Choose this single-acting spring-return model for clamping, ejecting, or gating tasks where the load must return to rest unpowered. Remember the 0.2 MPa pressure floor; below that, the spring wins and the rod will not extend. Mounting is versatile with LB foot, FA flange, SDB pivot, or TC trunnion brackets, and the rear CM cover provides a fixed round-end interface.
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 MSF32X80CM FAQ
This 32 mm bore cylinder provides a net push force of 323.3 N at 0.5 MPa and 484.1 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring; below that threshold, the spring will keep the rod retracted.
No, this specific SKU does not include a magnet. You must order the -S variant to use CMSG, DMSG, or EMSG magnetic switches. Additionally, the fixed TPU bumper pads absorb end-of-stroke impact, and the spring ensures the rod returns to a safe retracted position if air pressure is lost.
