Airtac MSF Single Acting Mini Cylinder MSF40X10SCM
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF40X10SCM is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø40mm bore and 10mm 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 MSF40X10SCM
Delivering 535.3 N of push force at 0.5 MPa (786.5 N at 0.7 MPa), this AirTAC MSF40X10SCM mini cylinder uses compressed air to extend the rod and an internal spring to retract it. Because it is single-acting, you only need to plumb one 1/4 inch port, simplifying valve requirements. The quoted force is already net of the return spring, and the body is notably shorter than an ISO 6432 unit of the same 40 mm bore and 10 mm stroke.
The riveted round-body construction pairs a SUS304 stainless steel barrel with aluminium covers, offering good resistance to mild corrosion and washdown environments. It features fixed TPU bumper pads for end-of-stroke deceleration across its 50-800 mm/s speed range. For practical sizing, expect a safe working load around 321 N, or a vertical lift capacity of roughly 27.3 kg with a 2:1 safety margin.

Where the Airtac MSF Single Acting Mini Cylinder MSF40X10SCM Is Used
Heavy Part Ejection
Pushes completed metal or plastic components out of a machining fixture with 535.3 N of force, relying on the spring to withdraw the rod cleanly between cycles.
Pallet Stopping Gate
Acts as a robust pneumatic stop for heavy pallets on a conveyor line, extending to block traffic and retracting to release flow when the air signal drops.
Product Diversion
Extends a diverter arm to push heavy cartons onto a secondary packaging track, using the fail-safe retracted position to keep the main line clear during jams.
Is the Airtac MSF Single Acting Mini Cylinder MSF40X10SCM the Right Cylinder?
When sizing this 40 mm bore unit, verify whether the 535.3 N @0.5 MPa output suits your load; if less force is needed, the smaller MSF32 provides 323.3 N @0.5 MPa. As this is the largest bore in the MSF family, there is no larger single-acting push option. Ensure your supply stays at or above the 0.2 MPa floor, otherwise the internal spring will overpower the air and keep the rod retracted.
This specific configuration includes a CM round-end rear cover and an -S magnet for position sensing. Add CMSG, DMSG, or EMSG switches directly to the groove for piston tracking. You can mount it using LB foot, FA flange, SDB pivot, or TC trunnion hardware to fit your frame.
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 MSF40X10SCM FAQ
It generates 535.3 N of push force at 0.5 MPa and 786.5 N at 0.7 MPa. Operating pressure must be between 0.2 and 1.0 MPa; the 0.2 MPa minimum is required to overcome the internal return spring.
No. On air loss, the spring drives the rod to the retracted position, so it cannot hold an arbitrary mid-stroke load. For held positioning, use a double-acting MF cylinder with an external rod lock.
