Airtac MSF Single Acting Mini Cylinder MSF32X25U
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF32X25U is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø32mm bore and 25mm stroke, 1/4" 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 MSF32X25U
Delivering 323.3 N of push force at 0.5 MPa, this AirTAC MSF32X25U 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 1/4" port, simplifying valve setup. The quoted force is already net of the return spring, and the U flat-end rear cover helps the body sit flush against machine frames.
Built with a SUS304 stainless round barrel and riveted aluminium covers, the JIS-standard housing is shorter than an ISO 6432 cylinder of the same 32 mm bore and 25 mm stroke, saving valuable mounting length. It uses fixed TPU bumper pads rather than an adjustable cushion. For a safe working load, expect about 194 N (60% of the 0.5 MPa rating), or roughly 16.5 kg of vertical lift with a 2:1 margin. This non-magnet SKU cannot host a sensor; specify the -S variant for CMSG, DMSG or EMSG switches.

Where the Airtac MSF Single Acting Mini Cylinder MSF32X25U Is Used
Part Ejection
Uses the 323.3 N push output to knock machined parts from a fixture, with the spring ensuring the rod retracts clear of the workspace on air loss.
Short-Stroke Clamping
Holds workpieces securely with a 194 N safe working load, relying on the 25 mm stroke and U flat-end cover for tight mounting envelopes.
Flow Gating
Actuates a diverter gate on a packaging line, where the single-acting design cuts piping complexity and fails safely to the closed position.
Is the Airtac MSF Single Acting Mini Cylinder MSF32X25U the Right Cylinder?
Size this 32 mm bore against the MSF25, which provides 192.8 N at 0.5 MPa, or step up to the MSF40 for 535.3 N if your application needs more thrust. The MSF32X25U requires at least 0.2 MPa of operating pressure to overcome the return spring, with a maximum of 1.0 MPa. It is ideal for simple clamping, ejecting or gating tasks where air loss safely drops the rod back to the retracted position. Mount it using LB foot, FA flange, SDB pivot or TC trunnion brackets, but note this specific SKU lacks the -S magnet and cannot support position sensing.
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 MSF32X25U FAQ
It generates 323.3 N of push force at 0.5 MPa and 484.1 N at 0.7 MPa. Because it is single-acting with a spring return, it requires a minimum operating pressure of 0.2 MPa to overcome the spring, with a maximum of 1.0 MPa. The 1/4" port supplies air to extend the rod.
No. On air loss the internal spring drives the rod to the retracted position, so it cannot hold an arbitrary mid-stroke load; use a double-acting MF with an external rod lock for that. Also, this non-magnet SKU cannot take CMSG, DMSG or EMSG switches unless you specify the -S variant.
