Airtac MSF Single Acting Mini Cylinder MSF20X100SCM
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF20X100SCM is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø20mm bore and 100mm 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 MSF20X100SCM
Generating 117.5 N of push force at 0.5 MPa (181.3 N at 0.7 MPa), this single-acting spring-return mini cylinder uses air to extend the rod and an internal spring to retract it. Because you only pipe and valve the single 1/8" port, plumbing is simpler, and the unit fails to the retracted position on air loss. The quoted force is already net of the return spring.
Built as a JIS-standard round-body unit with a SUS304 stainless barrel and riveted aluminium covers, the body is deliberately shorter than an ISO 6432 cylinder for the same 20 mm bore and 100 mm stroke, saving mounting length. The fixed TPU bumper pads absorb end-of-stroke impact, while the -S magnet supports CMSG, DMSG, and EMSG switches. For sizing, expect a safe working load of roughly 71 N or a vertical lift of about 6 kg with a 2:1 margin.

Where the Airtac MSF Single Acting Mini Cylinder MSF20X100SCM Is Used
Light Parts Ejection
Pushes small machined components out of a fixture using 117.5 N of force, relying on the spring to safely retract the rod when air is removed.
Packaging Flap Folding
Extends to fold light cardboard flaps during carton sealing, with the spring ensuring the mechanism retracts clear of the packaging path.
Compact Gate Diverting
Acts as a short-stroke diverter gate on a conveyor, using its space-saving JIS body and 1/8" single port to simplify pneumatic routing.
Is the Airtac MSF Single Acting Mini Cylinder MSF20X100SCM the Right Cylinder?
This 20 mm bore suits light clamping and ejection duties; if you need more push, step up to the MSF25 which yields 192.8 N at 0.5 MPa, as 20 mm is the smallest available option. Ensure your supply stays at or above the 0.2 MPa floor, otherwise the internal spring wins and the rod will not extend fully. The CM round-end back cover and 100 mm stroke fit compact envelopes, and the -S magnet version is required if you intend to mount CMSG, DMSG, or EMSG position 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 MSF20X100SCM FAQ
It provides a net push force of 117.5 N at 0.5 MPa and 181.3 N at 0.7 MPa. Because it is single-acting with a spring return, you must supply at least 0.2 MPa to overcome the internal spring and extend the rod.
No. On air loss the internal spring drives the rod back to its retracted rest position; it cannot hold an arbitrary mid-stroke load. The -S magnet allows CMSG, DMSG, or EMSG sensors to track the piston, but a double-acting MF with an external rod lock is needed for mid-stroke holding.
