Airtac MSF Single Acting Mini Cylinder MSF25X30CA
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF25X30CA is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø25mm bore and 30mm 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 MSF25X30CA
Delivering 192.8 N of push force at 0.5 MPa, this single-acting stainless mini cylinder uses compressed air to extend the rod and an internal spring to retract it. Because you only plumb one 1/8" port, valve complexity drops, and the unit safely fails to the retracted position on air loss. The JIS-standard round-body construction with a SUS304 barrel and riveted aluminium covers is shorter than an ISO 6432 cylinder of the same bore and stroke, saving valuable machine space.
The quoted push force is already net of the return spring, meaning the full 192.8 N is available for your work. For practical sizing, this equates to a safe working load of roughly 116 N, or a vertical lift capacity of about 9.8 kg with a 2:1 safety margin. This specific SKU lacks a magnet and cannot accept position sensors; adding the -S option enables CMSG, DMSG, or EMSG switches. End-of-stroke deceleration is handled by fixed TPU bumper pads.

Where the Airtac MSF Single Acting Mini Cylinder MSF25X30CA Is Used
Spring-Return Clamping
Uses the 192.8 N push output to hold parts firmly during machining, automatically releasing to the retracted position if air pressure drops.
Package Ejection Gate
Extends 30 mm to deflect items on a line, relying on the internal spring to snap the gate shut quickly when the single air line vents.
Light Lift & Transfer
Raises lightweight fixtures or components up to 9.8 kg, saving space with a compact JIS body that is shorter than standard ISO 6432 alternatives.
Is the Airtac MSF Single Acting Mini Cylinder MSF25X30CA the Right Cylinder?
When sizing this 25 mm bore, compare it directly against its neighbors: the MSF20 provides 117.5 N at 0.5 MPa, while the MSF32 offers 323.3 N. Choose this model when your application requires a spring-return action for clamping or ejecting, and ensure your air supply stays at or above the 0.2 MPa floor to overcome the internal spring. The integrated CA rear pivot cover simplifies body mounting, and you can pair it with LB foot or FA flange brackets if needed.
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 MSF25X30CA FAQ
It generates 192.8 N of push force at 0.5 MPa and 290.9 N at 0.7 MPa. These figures are net of the return spring. Operating pressure must be maintained between 0.2 and 1.0 MPa, as a minimum of 0.2 MPa is required to overcome the spring.
No, this specific SKU does not include a magnet and cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. The cylinder features a CA pivot cover, SUS304 stainless barrel, and fixed TPU bumper pads.
