Airtac MSF Single Acting Mini Cylinder MSF25X60U
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF25X60U is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø25mm bore and 60mm 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 MSF25X60U
Delivering 192.8 N of push force at 0.5 MPa (290.9 N at 0.7 MPa), this JIS-standard round-body mini cylinder uses a single air line to extend the rod, while an internal spring handles the retraction. The SUS304 stainless barrel and riveted aluminium covers resist mild washdown, and because it is spring-returned, the unit naturally fails to the retracted position if air pressure drops. This base SKU lacks a magnet and cannot accept position sensors.
The 25 mm bore pairs a 10 mm rod with a 1/8" port and a 60 mm stroke, terminated here by a U flat-end rear cover. The quoted forces are already net of the return spring, which requires at least 0.2 MPa to overcome. For practical sizing, this bore yields a safe working load of roughly 116 N, or a vertical lift capacity of about 9.8 kg with a 2:1 safety margin.

Where the Airtac MSF Single Acting Mini Cylinder MSF25X60U Is Used
Spring-Return Clamping
Provides 192.8 N of push at 0.5 MPa to hold parts, releasing them automatically when air is removed and the spring retracts.
Package Ejector
Uses the 60 mm stroke to push light goods off a belt, relying on the single-acting design to simplify valve plumbing.
Gravity Gate Actuation
Extends to open a diverter gate and lets the internal spring pull it shut, ensuring a closed default state during air loss.
Is the Airtac MSF Single Acting Mini Cylinder MSF25X60U the Right Cylinder?
When sizing this unit, step down to the MSF20 for lighter duties (117.5 N at 0.5 MPa) or up to the MSF32 if you need greater thrust (323.3 N at 0.5 MPa). The spring-return action is ideal for clamping, ejecting, or gating tasks where the load must retract automatically on air loss, but remember the rod cannot be loaded in the return direction.
Ensure your supply stays at or above the 0.2 MPa floor so the spring does not win. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion brackets. Because this specific SKU has no internal magnet, it cannot host CMSG, DMSG, or EMSG switches; specify the -S variant if you require 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 MSF25X60U FAQ
The single-acting push force is 192.8 N at 0.5 MPa and 290.9 N at 0.7 MPa, already net of the spring. It requires a minimum operating pressure of 0.2 MPa to overcome the return spring.
No. On air loss the spring drives the rod to the retracted position; it will not hold an arbitrary mid-stroke load. Also, this base SKU lacks a magnet, so it cannot take CMSG/DMSG/EMSG switches—you need the -S variant for sensing.
