Airtac MSF Single Acting Mini Cylinder MSF40X75CA
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF40X75CA is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø40mm bore and 75mm 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 MSF40X75CA
Delivering 535.3 N of push force at 0.5 MPa, this AirTAC MSF40X75CA is the largest bore in the JIS-standard round-body mini line. As a single-acting push cylinder, compressed air entering the 1/4" port extends the Ø16 mm rod, while an internal spring handles the return. This means you only plumb and valve one port, and the cylinder defaults to a safe retracted state on air loss. The quoted force is already net of the spring, which requires a 0.2 MPa floor to overcome.
Built with a SUS304 stainless barrel and riveted aluminium covers, the body resists mild corrosion and washdown. It is also shorter than an ISO 6432 cylinder for the same 40 mm bore and 75 mm stroke, saving valuable mounting length. The stroke ends are decelerated by fixed TPU bumper pads rather than an adjustable cushion. For practical sizing, a safe working load is roughly 321 N, or it can vertically lift about 27.3 kg with a 2:1 margin. This SKU lacks a magnet, so it cannot take a sensor; adding the -S option enables CMSG, DMSG, or EMSG switches.

Where the Airtac MSF Single Acting Mini Cylinder MSF40X75CA Is Used
Heavy-Duty Clamping
Use the 535.3 N push force to secure heavy workpieces during machining, with the spring ensuring the clamp retracts safely when air is removed.
Package Ejector
Eject heavier finished goods from a conveyor line; the single 1/4" port simplifies valve requirements for this push-only action.
Pallet Gate Actuator
Actuate a diverter gate on a pallet line, relying on the SUS304 stainless body to withstand dusty or mildly humid warehouse environments.
Is the Airtac MSF Single Acting Mini Cylinder MSF40X75CA the Right Cylinder?
When sizing this 40 mm bore, check both directions: stepping down to the MSF32 yields 323.3 N at 0.5 MPa, while no larger MSF bore exists. This model is ideal for spring-return clamping, ejecting, or gating tasks where air pressure only needs to drive the outward stroke. Ensure your supply stays at or above the 0.2 MPa floor, otherwise the return spring will overpower the air and prevent extension. The CA back cover provides a rear pivot mount, which pairs well with LB foot, FA flange, or TC trunnion options for your fixture. Remember that because this specific SKU has no -S magnet, position 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 MSF40X75CA FAQ
It generates 535.3 N of push force at 0.5 MPa and 786.5 N at 0.7 MPa. Because it is single-acting with a spring return, the force is net of the spring, and it requires a minimum operating pressure of 0.2 MPa to extend the rod.
No. On air loss, the spring drives the rod to the retracted position; it cannot hold an arbitrary mid-stroke load. For that, use a double-acting MF with an external rod lock. Additionally, this SKU lacks a magnet, so it cannot take CMSG, DMSG, or EMSG sensors without the -S option.
