Airtac MSF Single Acting Mini Cylinder MSF25X150SCM
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF25X150SCM 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 MSF25X150SCM
Delivering 192.8 N of push force at 0.5 MPa, this JIS-standard round-body mini cylinder uses a SUS304 stainless barrel and riveted aluminium covers. As a single-acting push type, air extends the 10 mm rod while an internal spring retracts it, meaning you only plumb one 1/8" port. The body is notably shorter than an ISO 6432 unit of identical bore and stroke, saving valuable machine space.
The quoted thrust is already net of the return spring, which dictates a 0.2 MPa minimum operating pressure. With a 150 mm stroke, fixed TPU bumper pads absorb end-of-travel impacts across the 50-800 mm/s speed range. The -S suffix adds a piston magnet for position sensing, and the CM round-end rear cover completes the assembly. For stable holding, expect a safe working load around 116 N, or roughly a 9.8 kg vertical lift with a 2:1 margin.

Where the Airtac MSF Single Acting Mini Cylinder MSF25X150SCM Is Used
Parts Ejection
Uses the 192.8 N push output to positively eject machined components from a fixture, relying on the spring to retract the rod safely when air is removed.
Package Gating
Actuates a 150 mm stroke diverter gate to sort lightweight cartons, defaulting to a closed rest state during pneumatic power loss.
Vertical Lift Stops
Raises a physical stop to catch items on a gravity conveyor, securely holding approximately 9.8 kg against gravity with a 2:1 safety margin.
Is the Airtac MSF Single Acting Mini Cylinder MSF25X150SCM the Right Cylinder?
When sizing this 25 mm bore, compare it both ways: step down to the MSF20 for 117.5 N @0.5 MPa, or up to the MSF32 for 323.3 N @0.5 MPa. Choose this single-acting spring-return format for clamping, ejecting, or gating tasks that must fail safely to the retracted position on air loss. Ensure your supply stays at or above the 0.2 MPa floor so pressure reliably beats the internal spring. The -S magnet pairs directly with CMSG, DMSG, or EMSG switches, while the CM back cover suits compact pivot or surface mounting.
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 MSF25X150SCM 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. Operating pressure must be 0.2 to 1.0 MPa, as a minimum of 0.2 MPa is required to overcome the spring and extend the rod.
Air pressure extends the rod, and the spring retracts it, meaning it cannot be loaded on the return stroke and will not hold a mid-stroke position without air. The -S option includes a magnet for CMSG, DMSG, or EMSG switches. It features a SUS304 stainless barrel, fixed TPU bumpers, and a 1/8" port.
