Airtac MSF Single Acting Mini Cylinder MSF40X60SCM
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF40X60SCM is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø40mm bore and 60mm 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 MSF40X60SCM
Delivering 535.3 N of push force at 0.5 MPa, this 40 mm bore pneumatic 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" port, simplifying valve requirements while ensuring the rod fails to the retracted position upon air loss. The JIS-standard round-body construction, featuring a SUS304 stainless barrel and riveted aluminium covers, is shorter than a comparable ISO 6432 unit, saving valuable mounting length.
The quoted thrust is already net of the return spring, which requires a minimum 0.2 MPa operating pressure to overcome. For practical sizing, expect a safe working load of roughly 321 N, or a vertical lift capacity of about 27.3 kg with a 2:1 safety margin. This specific configuration includes a CM round-end rear cover and a built-in piston magnet (-S) for position sensing, while fixed TPU bumper pads manage end-of-stroke deceleration across its 50-800 mm/s speed range.

Where the Airtac MSF Single Acting Mini Cylinder MSF40X60SCM Is Used
Heavy-Duty Part Ejection
Throws completed metal castings off a machining bed using 535.3 N of thrust, with the spring safely pulling the ejector pin back before the next cycle begins.
Package Diverting Gate
Pushes heavy cartons across a transfer line; the single-acting design ensures the gate retracts out of the conveyor path if the compressed air supply drops.
Pallet Stopper Arm
Holds a loaded pallet momentarily using the 321 N safe working load, then releases it by venting the single 1/4" air line to let the spring collapse the arm.
Is the Airtac MSF Single Acting Mini Cylinder MSF40X60SCM the Right Cylinder?
Choose this 40 mm bore when smaller units lack power; for context, the next size down (MSF32) provides 323.3 N at 0.5 MPa, whereas this model delivers 535.3 N at the same pressure. As the largest available MSF bore, there is no larger single-acting push option in the series. It fits best in spring-return clamping, ejecting, or gating tasks where losing air pressure safely retracts the 60 mm stroke. Ensure your supply stays at or above the 0.2 MPa floor so the spring does not win. The included -S magnet supports CMSG, DMSG, or EMSG switches, and mounting is flexible via LB foot, FA flange, SDB pivot, or TC trunnion brackets.
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 MSF40X60SCM FAQ
It generates 535.3 N of thrust at 0.5 MPa and 786.5 N at 0.7 MPa. These figures are net of the internal return spring. You must supply at least 0.2 MPa to overcome the spring and extend the rod, with a maximum operating pressure of 1.0 MPa.
No. The spring drives the rod to the retracted rest position on air loss; it cannot act as a controllable brake or hold a mid-stroke load. For held mid-stroke positioning, use a double-acting MF cylinder with an external rod lock. This unit also features a SUS304 stainless barrel and a -S magnet for CMSG/DMSG/EMSG sensors.
