Airtac MSF Single Acting Mini Cylinder MSF20X150SCM
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF20X150SCM is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø20mm bore and 150mm 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 MSF20X150SCM
Generating 117.5 N of push force at 0.5 MPa, this MSF20X150SCM mini cylinder uses compressed air to extend the rod and an internal spring to retract it. Because it is single-acting, you only pipe and valve one 1/8" port, and the rod fails to the retracted position on air loss. The SUS304 stainless round body and riveted aluminium covers yield a shorter mounting envelope than an ISO 6432 unit of the same bore and stroke, while resisting mild washdown corrosion. A built-in magnet (-S) enables position sensing, and the CM round-end rear cover supports direct mounting.
The quoted push force is already net of the return spring, meaning the cylinder cannot be loaded on the return stroke. With a safe working load of roughly 71 N, it can vertically lift or clamp about 6 kg with a 2:1 margin. Deceleration is handled by fixed TPU bumper pads rather than an adjustable cushion, keeping the 150 mm stroke impact controlled across the 50-800 mm/s speed range.

Where the Airtac MSF Single Acting Mini Cylinder MSF20X150SCM Is Used
Spring-Return Clamping
Provides 71 N of safe clamping force to hold light workpieces, automatically releasing to the retracted position if the air supply drops.
Part Ejection
Pushes finished components off a conveyor line with 117.5 N at 0.5 MPa, relying on the internal spring to reset the 150 mm stroke.
Flow Gating
Actuates light diverter gates in packaging lines; the SUS304 stainless body withstands intermittent washdown environments.
Is the Airtac MSF Single Acting Mini Cylinder MSF20X150SCM the Right Cylinder?
When sizing this 20 mm bore model, compare its 117.5 N @0.5 MPa output against the next size up: the MSF25 delivers 192.8 N @0.5 MPa if your clamp or ejector needs more force. As the smallest available MSF bore, there is no smaller option, so if 71 N of safe working load is excessive for your fixture, consider a different actuator type. Single-acting push operation fits spring-return clamping, gating, and ejection tasks perfectly, provided the system maintains at least a 0.2 MPa pressure floor to overcome the internal spring. Mount this unit using the CM round-end cover, and leverage the -S magnet for CMSG, DMSG, or EMSG switches.
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 MSF20X150SCM FAQ
The push force is 117.5 N at 0.5 MPa and 181.3 N at 0.7 MPa. These figures are net of the return spring. You must supply at least 0.2 MPa of air pressure to overcome the spring and extend the rod, with a maximum operating pressure of 1.0 MPa.
No, the internal spring drives the rod to the fully retracted rest position on air loss; it cannot hold an arbitrary mid-stroke load. For mid-stroke holding, use a double-acting MF cylinder with an external rod lock. This model includes a -S magnet for CMSG/DMSG/EMSG sensors.
