Airtac MSF Single Acting Mini Cylinder MSF25X25CM
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF25X25CM 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 MSF25X25CM
Delivering 192.8 N of push force at 0.5 MPa, this AirTAC MSF25X25CM is a JIS-standard round-body mini cylinder built for single-acting push operation. Air extends the 10 mm rod out of the SUS304 stainless barrel, while an internal spring retracts it, meaning you only need to plumb a single 1/8" port. The riveted aluminium covers and compact CM round-end rear cover ensure the overall body is noticeably shorter than an equivalent ISO 6432 unit, saving valuable mounting length.
Because the quoted force is already net of the return spring, you can confidently apply a safe working load of about 116 N or vertically lift roughly 9.8 kg with a 2:1 safety margin. The spring naturally drives the rod to the retracted rest position upon air loss, making it ideal for fail-safe clamping. Note this specific SKU lacks the -S magnet, so it cannot host CMSG, DMSG, or EMSG sensors.

Where the Airtac MSF Single Acting Mini Cylinder MSF25X25CM Is Used
Short-Stroke Clamping
Uses the 192.8 N push force at 0.5 MPa to secure light metal workpieces, safely releasing them to the retracted position if the air supply drops.
Part Ejector Gate
The 25 mm stroke and compact CM round-end body fit tightly along a conveyor to push small finished products off the line into a bin.
Carton Flap Hold
Extends to hold packaging flaps open during a fill cycle, relying on the internal spring to quickly retract the 10 mm rod out of the way.
Is the Airtac MSF Single Acting Mini Cylinder MSF25X25CM the Right Cylinder?
When sizing this 25 mm bore, compare it directly against the MSF20, which offers 117.5 N of push at 0.5 MPa, or step up to the MSF32 for 323.3 N if your ejection task requires more authority. Single-acting spring-return cylinders excel in simple clamping, ejecting, or gating tasks where air loss must default to a safe retracted state. You must supply at least 0.2 MPa of operating pressure to overcome the internal spring, with a maximum limit of 1.0 MPa. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion brackets to suit your 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 MSF25X25CM FAQ
This single-acting cylinder provides a net push force of 192.8 N at 0.5 MPa and 290.9 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the return spring, and uses a 1/8" air port.
No, this specific SKU does not include the -S magnet option, so it cannot host CMSG, DMSG, or EMSG switches. The SUS304 stainless barrel resists mild corrosion, and fixed TPU bumper pads absorb the stroke end impact.
