Airtac MSF Single Acting Mini Cylinder MSF25X15CM
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF25X15CM is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø25mm bore and 15mm 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 MSF25X15CM
Delivering 192.8 N of push force at 0.5 MPa, this 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 1/8" port, simplifying valve setups while ensuring the rod 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 notably shorter than an ISO 6432 cylinder of the same 25 mm bore and 15 mm stroke.
The quoted thrust is already net of the return spring, which demands a minimum 0.2 MPa operating pressure to overcome. For practical sizing, anticipate a safe working load of roughly 116 N, or a vertical lift capacity of about 9.8 kg with a 2:1 safety margin. This specific SKU lacks the -S magnet option, so it cannot host CMSG, DMSG, or EMSG position sensors.

Where the Airtac MSF Single Acting Mini Cylinder MSF25X15CM Is Used
Short-Stroke Clamping
Uses the 192.8 N thrust to secure light workpieces during machining, releasing automatically to the retracted state when air is removed.
Part Ejector
Pushes finished components off a conveyor line with a rapid 15 mm extension, relying on the internal spring for a fast return cycle.
Bin Diverter Gate
Actuates a short diverter flap in sorting stations, where the fail-safe retracted position prevents product jams during power loss.
Is the Airtac MSF Single Acting Mini Cylinder MSF25X15CM the Right Cylinder?
When sizing this 25 mm bore, verify if the 192.8 N push at 0.5 MPa suits your load; if not, step down to the MSF20 (117.5 N) or up to the MSF32 (323.3 N). The 15 mm stroke is ideal for very short ejection or clamping tasks. Remember the 0.2 MPa pressure floor needed to beat the spring. Mounting is versatile via LB foot, FA flange, SDB pivot, or TC trunnion brackets, and the CM round-end rear cover fits tight spaces. Because this non-magnetic SKU cannot take a sensor, order an -S variant if you need CMSG/DMSG/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 MSF25X15CM 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 internal return spring, and utilizes a 1/8" port.
No, this specific SKU does not include a magnet. You must select the -S option to use CMSG, DMSG, or EMSG magnetic switches. Additionally, the spring only returns the rod to rest; it will not hold a mid-stroke load, for which a double-acting MF with a rod lock is required.
