Airtac MSF Single Acting Mini Cylinder MSF20X100CA
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF20X100CA 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 MSF20X100CA
Delivering 117.5 N of push force at 0.5 MPa, the AirTAC MSF20X100CA is a single-acting, spring-return mini cylinder built to JIS standards. Air extends the 8 mm rod through its 100 mm stroke, while an internal spring handles retraction, meaning you only need to plumb a single 1/8" port. The quoted force is already net of the spring, yielding a safe working load of roughly 71 N or a vertical lift capacity of about 6 kg with a 2:1 margin.
This round-body unit uses a SUS304 stainless barrel with riveted aluminium covers, offering mild corrosion resistance while saving mounting length compared to an ISO 6432 cylinder. It features fixed TPU bumper pads, operates between 50-800 mm/s, and includes a CA rear pivot cover. Note this SKU lacks the -S magnet, so it cannot host CMSG, DMSG, or EMSG sensors.

Where the Airtac MSF Single Acting Mini Cylinder MSF20X100CA Is Used
Light-Duty Clamping
Provides 117.5 N of push force at 0.5 MPa to secure light components during machining, releasing automatically on air loss.
Package Ejection
Uses the 100 mm stroke to push small items off a conveyor belt, relying on the internal spring to retract the rod quickly.
Sortation Gating
Acts as a compact diverter arm with a CA pivot mount, handling products weighing up to roughly 6 kg safely.
Is the Airtac MSF Single Acting Mini Cylinder MSF20X100CA the Right Cylinder?
If 71 N of safe working load is insufficient, step up to the MSF25, which provides 192.8 N at 0.5 MPa; there is no smaller MSF bore below 20 mm. This 20 mm bore is ideal for simple clamping, ejecting, or gating tasks where air loss safely defaults the rod to the retracted position. Ensure your supply stays at or above the 0.2 MPa floor, otherwise the spring will overpower the air and prevent extension. Pair the CA pivot cover with an appropriate clevis mount, and if position feedback is required, switch to the -S magnet variant for sensor compatibility.
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 MSF20X100CA FAQ
This single-acting cylinder generates 117.5 N of push force at 0.5 MPa and 181.3 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the return spring, with a maximum of 1.0 MPa and a proof pressure of 1.5 MPa.
No, this specific SKU does not include a magnet, so it cannot host CMSG, DMSG, or EMSG switches. You must select the -S variant for sensing capabilities. Additionally, the spring only returns the rod to rest on air loss; it will not hold a mid-stroke load.
