Airtac MSF Single Acting Mini Cylinder MSF40X75SCM
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF40X75SCM 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 MSF40X75SCM
Delivering 535.3 N of push force at 0.5 MPa, this 40 mm bore JIS-standard round-body mini cylinder uses air to extend the rod and an internal spring to retract it. Because it is single-acting, you only plumb one 1/4" port, simplifying valve requirements while ensuring the rod fails to the retracted position on air loss. The SUS304 stainless barrel shrinks mounting length compared to ISO 6432 equivalents and provides mild washdown resistance.
The quoted output is already net of the return spring, yielding a safe working load of roughly 321 N or a vertical lift of about 27.3 kg with a 2:1 margin. This MSF40X75SCM variant includes a built-in magnet for position sensing and a CM round-end rear cover. End-of-stroke deceleration relies on fixed TPU bumper pads rather than an adjustable air cushion.

Where the Airtac MSF Single Acting Mini Cylinder MSF40X75SCM Is Used
Heavy Duty Clamping
Exerts 535.3 N at 0.5 MPa to secure heavy metal workpieces during machining, releasing automatically to the retracted state when air pressure drops.
Product Ejection
Pushes finished parts off a conveyor line with a 321 N safe working load, relying on the internal spring to withdraw the 16 mm rod quickly between cycles.
Pallet Gating
Acts as a robust stop gate for heavy pallets, lifting loads up to 27.3 kg vertically with a 2:1 safety margin before spring-returning to clear the lane.
Is the Airtac MSF Single Acting Mini Cylinder MSF40X75SCM the Right Cylinder?
If 323.3 N from the smaller MSF32 at 0.5 MPa is insufficient, this 40 mm bore is the maximum available in the series, providing 535.3 N at 0.5 MPa and 786.5 N at 0.7 MPa. Ensure your supply meets the 0.2 MPa minimum floor required to overcome the internal spring before extension begins. Match your mounting needs using LB foot, FA flange, SDB pivot, or TC trunnion brackets, and pair the integrated magnet with CMSG, DMSG, or EMSG switches for reliable position feedback.
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 MSF40X75SCM FAQ
It generates 535.3 N of push force at 0.5 MPa and 786.5 N at 0.7 MPa. Operating pressure ranges from 0.2 MPa to 1.0 MPa, with a 0.2 MPa minimum floor required to overcome the return spring.
No, the internal spring drives the rod to the fully retracted rest position on air loss, functioning as a fail-safe rather than a controllable brake. For mid-stroke holding, use a double-acting MF cylinder with an external rod lock.
