Airtac MSF Single Acting Mini Cylinder MSF20X20SCA
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF20X20SCA is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø20mm bore and 20mm stroke, 1/8" 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 MSF20X20SCA
Generating 117.5 N of push force at 0.5 MPa, this AirTAC MSF20X20SCA 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 1/8" port, simplifying valve requirements. The quoted force is already net of the return spring, and it cannot be loaded on the retract stroke.
Built with a JIS-standard SUS304 stainless round body and riveted aluminium covers, it is shorter than an ISO 6432 cylinder for the same 20 mm bore and 20 mm stroke, saving valuable mounting length. The fixed TPU bumper pads absorb end-of-stroke impacts across the 50-800 mm/s speed range. Factoring a 60% safety margin, the safe working load is roughly 71 N, making it suitable for clamping about 6 kg vertically.

Where the Airtac MSF Single Acting Mini Cylinder MSF20X20SCA Is Used
Spring-Return Clamping
Uses 117.5 N of air pressure to extend and clamp parts, automatically releasing to a safe retracted position if the air supply drops.
Package Ejector
Pushes lightweight goods off a belt with a 20 mm stroke, relying on the internal spring to cycle back without needing a second air line.
Pivot Gate Actuator
Pairs with the CA rear pivot to swing a diverter gate open on air, letting the spring close it securely during downtime.
Is the Airtac MSF Single Acting Mini Cylinder MSF20X20SCA the Right Cylinder?
If 117.5 N at 0.5 MPa is insufficient, step up to the MSF25 which provides 192.8 N; as this is the smallest bore in the MSF family, there is no smaller size to drop down to. This 20 mm bore is ideal for single-acting tasks like spring-return clamping, ejecting, or gating where air loss safely retracts the rod. Ensure your supply meets the 0.2 MPa minimum floor required to overcome the spring. The included -S magnet supports CMSG, DMSG, and EMSG sensors, while the CA pivot back cover suits articulated rod-end loads.
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 MSF20X20SCA FAQ
It delivers 117.5 N of push force at 0.5 MPa and 181.3 N at 0.7 MPa. Because it is single-acting with a spring return, the pressure must be at least 0.2 MPa to overcome the spring, with a maximum operating pressure of 1.0 MPa.
No, the internal spring drives the rod to the retracted rest position on air loss; it cannot hold an arbitrary mid-stroke load. For position holding you need a double-acting MF cylinder with an external rod lock. The SUS304 stainless barrel resists mild washdown environments.
