Airtac MSF Single Acting Mini Cylinder MSF25X75SCM
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF25X75SCM is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø25mm bore and 75mm 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 MSF25X75SCM
Delivering 192.8 N of push force at 0.5 MPa, this AirTAC MSF25X75SCM mini cylinder uses compressed 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, simplifying setup. The quoted force is already net of the return spring, meaning the rod cannot be loaded on the return stroke. This JIS-standard round-body unit features a SUS304 stainless barrel and riveted aluminium covers, offering a shorter mounting envelope than an ISO 6432 cylinder of the same bore and stroke while resisting mild washdown corrosion. The CM round-end back cover and built-in magnet (-S) round out the configuration.
For practical sizing, the 192.8 N output at 0.5 MPa translates to a safe working load of about 116 N, or roughly 9.8 kg of vertical lift with a 2:1 margin. It requires a minimum operating pressure of 0.2 MPa to overcome the spring and travels at 50-800 mm/s. End-of-stroke deceleration is handled by fixed TPU bumper pads rather than an adjustable air cushion. The integrated magnet enables position sensing with CMSG, DMSG, or EMSG switches.

Where the Airtac MSF Single Acting Mini Cylinder MSF25X75SCM Is Used
Spring-Return Clamping
Uses 192.8 N of push force at 0.5 MPa to secure parts during machining, relying on the internal spring to automatically release the clamp if air pressure drops.
Part Ejector Gate
Extends 75 mm to push completed components off a conveyor line, safely defaulting to the retracted position during an emergency stop to clear the path.
Light Vertical Lift
Raises lightweight trays weighing up to 9.8 kg with a 2:1 safety margin, using a single 1/8" air line to extend the rod before the spring lowers the load.
Is the Airtac MSF Single Acting Mini Cylinder MSF25X75SCM the Right Cylinder?
When sizing this 25 mm bore, compare it directly against its neighbours: 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 if your clamp or ejector needs more punch. This single-acting design is ideal for applications that must fail safe to the retracted position on air loss, provided you maintain at least 0.2 MPa working pressure to beat the internal spring. With its CM round-end cover, you can pivot-mount it directly, and the -S magnet option lets you track stroke completion with CMSG, DMSG, or EMSG sensors.
Quick checklist

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 MSF25X75SCM FAQ
The single-acting push force is 192.8 N at 0.5 MPa and 290.9 N at 0.7 MPa, measured net of the return spring. You must supply at least 0.2 MPa of air pressure to overcome the spring and extend the rod.
No, on air loss the internal spring drives the rod to the fully retracted position, so it cannot hold an arbitrary mid-stroke load. For held mid-stroke positioning you need a double-acting MF cylinder with an external rod lock.
