Airtac MSF Single Acting Mini Cylinder MSF25X150SCA
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF25X150SCA is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø25mm bore and 150mm 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 MSF25X150SCA
Delivering 192.8 N of push force at 0.5 MPa (290.9 N at 0.7 MPa), this AirTAC MSF25X150SCA 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 your setup while ensuring the rod fails to the retracted position on air loss. The quoted force is already net of the return spring.
Built as a JIS-standard round-body unit, it 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. The fixed TPU bumper pads absorb end-of-stroke impact across the 150 mm travel. For practical sizing, expect a safe working load of roughly 116 N, or a vertical lift capacity of about 9.8 kg with a 2:1 margin.

Where the Airtac MSF Single Acting Mini Cylinder MSF25X150SCA Is Used
Part Ejection
Uses the 192.8 N push output to positively eject stamped parts from a die, relying on the internal spring to withdraw the rod once air is removed.
Package Gating
Extends 150 mm to act as a traffic gate on a conveyor line, safely halting cartons until the air signal drops and the spring retracts the barrier.
Light Clamping
Secures light workpieces during machining, providing a reliable hold that automatically releases to the retracted position if the air supply is interrupted.
Is the Airtac MSF Single Acting Mini Cylinder MSF25X150SCA the Right Cylinder?
When sizing this 25 mm bore, compare its 192.8 N @0.5 MPa output against the smaller MSF20 (117.5 N) or the larger MSF32 (323.3 N) to match your exact load. It requires a minimum operating pressure of 0.2 MPa to overcome the internal spring, with a maximum of 1.0 MPa. This single-acting configuration is ideal for simple clamping, ejecting, or gating tasks where the return motion is unloaded.
The CA rear pivot cover suits angular articulation, and you can pair it with LB foot, FA flange, or TC trunnion mounts. Because this SKU includes the -S magnet, it supports CMSG, DMSG, and EMSG position switches for end-of-stroke confirmation.
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 MSF25X150SCA FAQ
It generates 192.8 N of push force at 0.5 MPa and 290.9 N at 0.7 MPa. The operating pressure ranges from 0.2 MPa (the minimum required to overcome the return spring) up to 1.0 MPa, with a 1.5 MPa proof pressure.
No. On air loss, the internal spring drives the rod to the fully retracted position; it cannot hold an arbitrary mid-stroke load. For mid-stroke holding, use a double-acting MF cylinder with an external rod lock.
