Airtac MSF Single Acting Mini Cylinder MSF25X75CA
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF25X75CA 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 MSF25X75CA
Delivering 192.8 N of push force at 0.5 MPa, this JIS-standard round-body mini cylinder uses air to extend the rod and an internal spring to retract it. Because it is single-acting, you only plumb one 1/8" port, which simplifies valve requirements and ensures the rod fails to the retracted position on air loss. The SUS304 stainless steel barrel shrinks mounting length compared to an ISO 6432 unit while resisting mild washdown corrosion.
The quoted output is already net of the return spring, meaning it cannot be loaded on the retract stroke. Factoring a conservative 60% margin, the safe working load is about 116 N, making it suitable for vertically lifting roughly 9.8 kg with a 2:1 safety ratio. End-of-stroke deceleration relies on fixed TPU bumper pads rather than an adjustable air cushion. Note this SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors without switching to an -S variant.

Where the Airtac MSF Single Acting Mini Cylinder MSF25X75CA Is Used
Pivot-Body Clamping
Leverage the CA rear pivot to swing a 116 N clamp onto irregularly shaped parts, letting the spring safely retract the arm when air is cut.
Package Diverter Gate
Extend a 75 mm stroke to push light cartons off a belt; the spring-return design guarantees the gate opens safely during an e-stop.
9.8 kg Vertical Lift
Raise lightweight platens or trays directly against gravity, taking advantage of the 192.8 N push force to lift loads under 10 kg.
Is the Airtac MSF Single Acting Mini Cylinder MSF25X75CA the Right Cylinder?
When sizing this 25 mm bore, compare it both ways: step down to the MSF20 for 117.5 N at 0.5 MPa, or up to the MSF32 for 323.3 N at 0.5 MPa. Ensure your supply stays at or above the 0.2 MPa floor, otherwise the internal spring will overpower the air and prevent extension. The integrated CA rear pivot makes it ideal for pivoting mechanisms, and you can pair it with LB foot, FA flange, or TC trunnion mounts if your geometry changes.
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 MSF25X75CA 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 to 1.0 MPa, but you must maintain at least 0.2 MPa to overcome the internal return spring.
No, this specific SKU does not include a magnet, so it cannot host CMSG, DMSG, or EMSG switches. You must select an MSF25X75CA-S variant to enable magnetic sensing on the SUS304 stainless steel barrel.
