Airtac MSF Single Acting Mini Cylinder MSF25X25SCM
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF25X25SCM is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø25mm bore and 25mm stroke, 1/8" 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 MSF25X25SCM
Delivering a net 192.8 N of push force at 0.5 MPa, this AirTAC MSF25X25SCM 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 1/8" port, simplifying valve requirements while ensuring the rod fails safely to the retracted position upon air loss. The SUS304 stainless round body and riveted aluminium covers form a compact JIS-standard assembly that is notably shorter than an equivalent ISO 6432 unit, saving valuable mounting length.
The built-in piston magnet (-S) supports CMSG, DMSG, and EMSG position switches for end-of-stroke confirmation. Fixed TPU bumper pads absorb impact energy at the stroke extremes, operating across a 50-800 mm/s speed range. For practical sizing, the 192.8 N output translates to a safe working load of roughly 116 N, or a vertical lift capacity of about 9.8 kg when applying a 2:1 safety margin. The CM round-end rear cover completes this 25 mm bore, 25 mm stroke configuration.

Where the Airtac MSF Single Acting Mini Cylinder MSF25X25SCM Is Used
Parts Ejection
Pushes finished components out of a machining fixture with 192.8 N of force, relying on the spring to retract the 10 mm rod clear of the workspace.
Package Gating
Acts as a single-line diverter gate that extends to halt carton flow and retracts automatically when air is removed, failing safe to an open state.
Light Clamping
Secures light workpieces during assembly using roughly 116 N of safe working load, releasing instantly when the air supply is cut.
Is the Airtac MSF Single Acting Mini Cylinder MSF25X25SCM the Right Cylinder?
When sizing this unit, evaluate both ends of the bore range: the MSF20 provides 117.5 N at 0.5 MPa if your load is lighter, while the MSF32 offers 323.3 N at 0.5 MPa for heavier demands. This 25 mm bore fits perfectly for spring-return clamping, ejecting, or gating tasks where air pressure only drives the extension. Maintain a minimum operating pressure of 0.2 MPa to overcome the return spring, and select your mounting hardware from LB foot, FA flange, SDB pivot, or TC trunnion options to suit the machine frame.
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 MSF25X25SCM FAQ
It generates 192.8 N of push force at 0.5 MPa and 290.9 N at 0.7 MPa. These figures are net of the internal spring. You must supply at least 0.2 MPa of air pressure to overcome the spring and extend the rod, with a maximum operating pressure of 1.0 MPa.
Air extends the rod, while the internal spring retracts it; it cannot be loaded on the return stroke. The -S designation means it has a built-in magnet for CMSG, DMSG, or EMSG sensors. The SUS304 stainless barrel resists mild corrosion, and the CM round-end cover provides flexible rear mounting.
