Airtac MSF Single Acting Mini Cylinder MSF25X80CA
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF25X80CA is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø25mm bore and 80mm 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 MSF25X80CA
Delivering 192.8 N of push force at 0.5 MPa, this AirTAC MSF25X80CA is a JIS-standard round-body mini cylinder built for single-acting operation. Air extends the 10 mm rod through an 80 mm stroke, while an internal spring handles the return, meaning you only plumb a single 1/8" port. The quoted force is already net of the spring, and the SUS304 stainless steel barrel resists mild washdown corrosion.
Because the spring drives the rod to a retracted rest position on air loss, it fails safely without holding a mid-stroke load. For practical sizing, a 2:1 safety margin gives a vertical lift capacity of about 9.8 kg. This SKU lacks a magnet, so it cannot take position sensors; adding the -S option enables CMSG, DMSG, or EMSG switches.

Where the Airtac MSF Single Acting Mini Cylinder MSF25X80CA Is Used
Spring-Return Clamping
Uses the 192.8 N push force to secure parts during machining, automatically releasing to the retracted position if air pressure drops.
Package Ejector Gate
Extends 80 mm to deflect cartons off a conveyor line, relying on the internal spring to quickly retract the gate between cycles.
Light Vertical Lift
Raises lightweight trays or fixtures straight up, safely handling loads around 9.8 kg with a 2:1 dynamic safety margin.
Is the Airtac MSF Single Acting Mini Cylinder MSF25X80CA 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. Ensure your supply stays at or above the 0.2 MPa floor, otherwise the internal spring will overpower the air and prevent extension. The fixed TPU bumper pads absorb end-of-stroke impact across the 50-800 mm/s speed range.
This configuration features a CA rear pivot cover, ideal for clevis mounting, and pairs with standard LB foot, FA flange, SDB pivot-block, or TC trunnion hardware. It is shorter than an ISO 6432 cylinder of equivalent size, saving valuable machine space. Note that without the -S magnet, magnetic sensing is unavailable.
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 MSF25X80CA FAQ
The net push force is 192.8 N at 0.5 MPa and 290.9 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring; below that, the cylinder will not extend.
No, this specific SKU does not include a magnet, so CMSG, DMSG, or EMSG switches cannot be used. You would need the -S variant for magnetic sensing. The CA rear cover also allows pivot mounting.
