Airtac MSF Single Acting Mini Cylinder MSF40X60SCA
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF40X60SCA 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 MSF40X60SCA
Delivering 535.3 N of push force at 0.5 MPa, this AirTAC MSF40X60SCA 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 a single 1/4 inch port, which simplifies valve requirements. The quoted force is already net of the return spring, meaning the full 535.3 N is available for your work.
Built as a JIS-standard round-body unit with a SUS304 stainless barrel and riveted aluminium covers, it occupies a shorter mounting envelope than an ISO 6432 cylinder of the same bore and stroke. The fixed TPU bumper pads absorb end-of-stroke impacts without needing adjustment. For practical sizing, expect a safe working load around 321 N, or a vertical lift capacity of about 27.3 kg with a 2:1 safety margin.

Where the Airtac MSF Single Acting Mini Cylinder MSF40X60SCA Is Used
Heavy-Duty Part Ejection
Uses the 535.3 N push stroke to positively eject finished metal or plastic components from a mould, relying on the spring to reset the rod safely.
Fail-Safe Work Holding
Clamps workpieces during machining; if air pressure drops, the spring automatically retracts the rod to release the part and prevent damage.
Vertical Lift Gates
Lifts light vertical gates or diverters weighing up to 27.3 kg, with the single-acting design ensuring the gate drops closed on air loss.
Is the Airtac MSF Single Acting Mini Cylinder MSF40X60SCA the Right Cylinder?
When sizing this 40 mm bore, check both ends of the range. If 535.3 N at 0.5 MPa is excessive, step down to the MSF32 which provides 323.3 N; since 40 mm is the largest available MSF bore, you cannot size up within this family. This model fits spring-return clamping or ejection tasks perfectly, but remember the 0.2 MPa pressure floor required to overcome the return spring. The included CA rear pivot cover suits trunnion-style mounting, and the -S magnet allows direct fitting of 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 MSF40X60SCA 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 internal return spring.
No. On air loss the internal spring drives the rod to the fully retracted position; it cannot hold an arbitrary mid-stroke load. For mid-stroke holding you need a double-acting MF cylinder with an external rod lock. The SUS304 stainless barrel also provides good washdown resistance.
