Airtac MSF Single Acting Mini Cylinder MSF25X100SCA
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF25X100SCA is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø25mm bore and 100mm 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 MSF25X100SCA
Delivering 192.8 N of push force at 0.5 MPa (290.9 N at 0.7 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 plumb one 1/8" port, simplifying valve requirements. The spring ensures the rod fails safely to the retracted position on air loss. The quoted force is already net of the spring, which requires a 0.2 MPa pressure floor to overcome.
Built with a JIS-standard round body, the riveted SUS304 stainless barrel and aluminium covers yield a shorter mounting envelope than an ISO 6432 unit of the same 25 mm bore and 100 mm stroke. This construction resists mild corrosion and washdown. The -S suffix adds a piston magnet for CMSG, DMSG or EMSG sensors, while the CA back cover provides a rear pivot. For sizing, expect a safe working load of roughly 116 N, or a vertical lift of about 9.8 kg with a 2:1 margin.

Where the Airtac MSF Single Acting Mini Cylinder MSF25X100SCA Is Used
Spring-Return Clamping
Uses the 192.8 N push force to secure parts during machining, automatically releasing to the retracted position if the air supply drops.
Package Diverter Gate
Extends 100 mm to route boxes on a line, relying on the internal spring to pull the gate back safely on signal loss.
Lightweight Vertical Lift
Raises components weighing up to roughly 9.8 kg with a 2:1 safety margin, using a single 1/8" air line for extension.
Is the Airtac MSF Single Acting Mini Cylinder MSF25X100SCA the Right Cylinder?
When sizing this 25 mm bore, verify your load against the 192.8 N @0.5 MPa output. If you need less force, the smaller MSF20 provides 117.5 N @0.5 MPa; if your application requires more thrust, step up to the MSF32 which yields 323.3 N @0.5 MPa. Remember the 0.2 MPa minimum operating pressure needed to beat the return spring.
This model fits spring-return clamping or ejection tasks where air loss must retract the tooling. The included CA rear pivot suits angular alignment, and the -S magnet enables position sensing. End-of-stroke deceleration relies on fixed TPU bumper pads across the 50-800 mm/s speed range.
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 MSF25X100SCA 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 internal 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 to the fully retracted position. It cannot hold an arbitrary mid-stroke load. For position holding you need a double-acting MF cylinder with an external rod lock. This unit uses fixed TPU bumper pads for end-of-stroke cushioning.
