Airtac MSF Single Acting Mini Cylinder MSF20X100U
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF20X100U 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 MSF20X100U
Delivering 117.5 N of push force at 0.5 MPa, this AirTAC mini cylinder uses air to extend the rod and an internal spring to retract it. Because it is single-acting, you only plumb one 1/8" port, simplifying valve setups. The spring ensures the rod fails safely to the retracted position on air loss, though it cannot hold a mid-stroke load. This SKU lacks a magnet and cannot accept position sensors.
Built as a JIS-standard round-body unit with a SUS304 stainless barrel and riveted aluminium covers, it offers 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 across the 100 mm travel. For practical sizing, expect a safe working load of about 71 N, which means it can vertically lift or clamp roughly 6 kg with a 2:1 safety margin.

Where the Airtac MSF Single Acting Mini Cylinder MSF20X100U Is Used
Light-Duty Clamping
Provides 71 N of safe clamping force to hold small plastic or aluminium components during drilling, utilizing the spring return to release the part automatically.
Parts Ejection
Pushes finished lightweight goods off a conveyor belt over the 100 mm stroke, retracting clear of the line when air is removed to prevent jams.
Vertical Lift Gate
Raises a small 6 kg sorting flap or gate using compressed air, relying on the internal spring to pull the gate back down to its resting state.
Is the Airtac MSF Single Acting Mini Cylinder MSF20X100U the Right Cylinder?
When sizing this 20 mm bore model, compare its 117.5 N push force at 0.5 MPa against the next size up: the MSF25 delivers 192.8 N if your application requires more thrust. If 117.5 N is sufficient, this bore is the optimal choice. Remember the 0.2 MPa pressure floor; below this, the return spring overcomes the air pressure and the rod will not extend. The U flat-end rear cover suits direct mounting, and you can pair it with LB foot, FA flange, SDB pivot, or TC trunnion brackets. Because this specific configuration lacks the -S magnet option, it cannot host 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 MSF20X100U FAQ
This single-acting cylinder provides a net push force of 117.5 N 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 internal return spring, with a maximum pressure of 1.0 MPa.
No, this specific SKU does not include a magnet. You must select an MSF model with the -S suffix to use CMSG, DMSG, or EMSG switches. Additionally, the spring only drives the rod to the retracted rest position on air loss; it will not hold a load mid-stroke.
