Airtac MSF Single Acting Mini Cylinder MSF25X10SCM
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF25X10SCM is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø25mm bore and 10mm 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 MSF25X10SCM
Delivering a net push force of 192.8 N at 0.5 MPa, this AirTAC mini cylinder uses air to extend the rod and an internal spring to retract it. Because it is single-acting, you only pipe and valve one 1/8" port, and it fails safely to the retracted position on air loss. The SUS304 stainless round body and riveted aluminium covers form a compact JIS-standard assembly that is shorter than an ISO 6432 unit of the same bore and stroke.
The 10 mm stroke and CM round-end rear cover make it ideal for tight clamping stations. The quoted thrust is already net of the return spring, and you must maintain at least 0.2 MPa to overcome that spring. For practical sizing, expect a safe working load of about 116 N, or a vertical lift capacity of roughly 9.8 kg with a 2:1 margin. The -S suffix means a piston magnet is present for position sensing.

Where the Airtac MSF Single Acting Mini Cylinder MSF25X10SCM Is Used
Short-Stroke Clamping
Uses the 192.8 N thrust to hold light machined parts securely during a brief 10 mm clamping cycle.
Package Ejector
Pushes small cartons off a belt with a quick 10 mm jab, relying on the internal spring to reset the rod.
Compact Diverter Gate
Pivots a lightweight routing flap in tight transfer lines where the short JIS body saves mounting length.
Is the Airtac MSF Single Acting Mini Cylinder MSF25X10SCM the Right Cylinder?
When sizing this 25 mm bore, compare it both ways: step down to an MSF20 for 117.5 N at 0.5 MPa, or step up to an MSF32 for 323.3 N at 0.5 MPa. Choose this single-acting spring-return model for simple clamping, ejecting, or gating tasks where the load cannot be pulled back against the rod. Remember the 0.2 MPa pressure floor; below that, the spring wins and the rod will not extend. The CM back cover suits compact foot or flange mounting, and the -S magnet enables CMSG, DMSG, or EMSG switches.
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 MSF25X10SCM FAQ
It generates 192.8 N of thrust at 0.5 MPa and 290.9 N at 0.7 MPa. These figures are net of the return spring. You must supply at least 0.2 MPa to overcome the spring and extend the rod, with a maximum operating pressure of 1.0 MPa.
No. On air loss, the internal spring drives the rod back to its fully retracted rest position; it cannot hold an arbitrary mid-stroke load. If you need mid-stroke holding, use a double-acting MF cylinder with an external rod lock. The -S magnet on this unit allows CMSG, DMSG, or EMSG sensors to track end-of-stroke position.
