Airtac MSF Single Acting Mini Cylinder MSF40X10CM
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF40X10CM 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 MSF40X10CM
Delivering 535.3 N of push force at 0.5 MPa (786.5 N at 0.7 MPa), this JIS-standard round-body mini cylinder uses a SUS304 stainless barrel and riveted aluminium covers. The MSF40X10CM is a single-acting push type: compressed air entering the 1/4" port extends the 16 mm rod, while an internal spring retracts it. Because the spring constantly pulls back, the quoted force is already net of spring resistance, and the rod cannot be loaded in the return direction.
This 40 mm bore unit offers a shorter mounting envelope than an ISO 6432 cylinder of the same size. It features fixed TPU bumper pads and a CM round-end rear cover. With a practical safe working load of roughly 321 N (about 60% of the 0.5 MPa rating), it can vertically lift or clamp around 27.3 kg with a 2:1 safety margin. Note that this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG position switches without upgrading to an -S variant.

Where the Airtac MSF Single Acting Mini Cylinder MSF40X10CM Is Used
Heavy Part Ejection
Uses the 535.3 N push force to positively eject dense machined metal parts from a fixture, with the spring ensuring the arm clears the workspace on air loss.
Fail-Safe Clamping
Secures heavy workpieces holding up to 27.3 kg against gravity, automatically releasing the clamp to a safe retracted state if the compressed air supply drops out.
Pallet Gating
Acts as a robust stop gate for heavy pallets on a conveyor line, extending to halt flow and relying on the internal spring to snap quickly out of the path.
Is the Airtac MSF Single Acting Mini Cylinder MSF40X10CM the Right Cylinder?
When sizing this 40 mm bore, evaluate both directions: stepping down to the MSF32 yields 323.3 N at 0.5 MPa, while the MSF40 is the largest available bore in this series. The MSF40X10CM suits applications needing robust ejection or clamping that automatically retracts when air is removed. A minimum operating pressure of 0.2 MPa is required to overcome the return spring. For mounting, pair the CM back cover with standard LB foot, FA flange, SDB pivot, or TC trunnion brackets. If position feedback is required, select the -S magnet option to enable CMSG, DMSG, or EMSG sensors.
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 MSF40X10CM FAQ
The 40 mm bore generates 535.3 N of push force at 0.5 MPa and 786.5 N at 0.7 MPa. These figures are net of the internal return spring. Operating pressure must be between 0.2 MPa and 1.0 MPa, as a minimum of 0.2 MPa is required to overcome the spring and extend the rod.
No, this specific SKU does not include a magnet. To use CMSG, DMSG, or EMSG magnetic switches, you must select the -S variant of the MSF40. Additionally, the spring drives the rod to the retracted position on air loss; it will not hold a mid-stroke load.
