Airtac MSF Single Acting Mini Cylinder MSF25X150CA
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF25X150CA is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø25mm bore and 150mm 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 MSF25X150CA
Delivering 192.8 N of push force at 0.5 MPa, this AirTAC MSF25X150CA mini cylinder uses compressed air to extend the rod and an internal spring to retract it. Because it is single-acting, you only plumb one 1/8" port, simplifying valve requirements. The quoted force is already net of the return spring, yielding a safe working load of roughly 116 N or a 9.8 kg vertical lift with a 2:1 margin.
Built as a JIS-standard round-body unit, it features a SUS304 stainless barrel and riveted aluminium covers that resist mild washdown environments. This design is shorter than an ISO 6432 cylinder for the same 25 mm bore and 150 mm stroke, saving valuable machine space. A CA rear pivot cover is integrated for direct mounting. Note this SKU lacks a magnet, so it cannot host CMSG or DMSG switches without the -S option.

Theoretical Output Force (Ø25mm)
| Pressure | Push force (spring return) |
|---|---|
| 0.5 MPa | 192.8 N |

Where the Airtac MSF Single Acting Mini Cylinder MSF25X150CA Is Used
Part Ejection
Pushes finished components off a conveyor with 192.8 N at 0.5 MPa, retracting automatically via spring when air cuts off.
Spring-Return Clamping
Secures light workpieces during machining, using a single 1/8" air line to extend the 10 mm rod for the 150 mm stroke.
Gate Diversion
Acts as a diverter arm that safely defaults to the retracted position on air loss, preventing line jams.
Is the Airtac MSF Single Acting Mini Cylinder MSF25X150CA the Right Cylinder?
When sizing this 25 mm bore, compare it both ways: an MSF20 provides 117.5 N at 0.5 MPa, while an MSF32 offers 323.3 N. This model fits spring-return clamping or ejecting tasks where air loss safely retracts the load. Maintain at least 0.2 MPa operating pressure to overcome the spring. The CA back cover suits pivot mounting; add the -S option if you need 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 MSF25X150CA FAQ
It generates 192.8 N of push force at 0.5 MPa and 290.9 N at 0.7 MPa. Because it is single-acting with a spring return, it requires a minimum operating pressure of 0.2 MPa to overcome the internal spring.
No. On air loss the spring drives the rod to the retracted position; it cannot hold an arbitrary mid-stroke load. Additionally, this specific SKU lacks a magnet, so it cannot take CMSG or DMSG sensors without upgrading to the -S variant.
