Airtac MSF Single Acting Mini Cylinder MSF20X75CA
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF20X75CA is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø20mm bore and 75mm 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 MSF20X75CA
Generating 117.5 N of push force at 0.5 MPa, this AirTAC MSF20X75CA 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, which simplifies automation and ensures the rod fails to the retracted position if air pressure drops. The quoted force is already net of the return spring, and the 75 mm stroke is stopped by fixed TPU bumper pads rather than an adjustable cushion.
Built as a JIS-standard round-body unit with a SUS304 stainless barrel and riveted aluminium covers, it occupies a shorter mounting envelope than an ISO 6432 cylinder of the same bore and stroke. For practical sizing, expect a safe working load of roughly 71 N, or a vertical lift capacity of about 6 kg with a 2:1 margin. This non-magnet SKU cannot host position sensors; adding the -S option enables CMSG, DMSG, or EMSG switches.

Where the Airtac MSF Single Acting Mini Cylinder MSF20X75CA Is Used
Small Part Clamping
Pushes a light jaw forward to hold a workpiece with roughly 71 N of safe force, relying on the spring to release the clamp when air is cut.
Package Ejector
Extends 75 mm to knock lightweight cartons off a belt, using the fail-safe retracted rest position to avoid blocking the line during downtime.
Diversion Gate
Pivots a sorting flap on the line edge; the CA rear cover provides a tidy pivot mount for this repetitive, low-force routing motion.
Is the Airtac MSF Single Acting Mini Cylinder MSF20X75CA the Right Cylinder?
When sizing this 20 mm bore model, step up to the MSF25 if you need 192.8 N at 0.5 MPa, as the 20 mm bore is the smallest available in the MSF family. Single-acting push logic fits clamping, ejecting, and gating tasks where the spring naturally retracts the load. Maintain at least 0.2 MPa of operating pressure so air overcomes the spring, and pair the CA rear pivot cover with an FA flange or LB foot mount as your frame requires. Because this specific SKU lacks the -S magnet, it cannot accept 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 MSF20X75CA FAQ
It delivers a net push force of 117.5 N at 0.5 MPa and 181.3 N at 0.7 MPa. Operating pressure must stay between 0.2 and 1.0 MPa, as a minimum of 0.2 MPa is required to overcome the internal return spring.
No. On air loss the spring drives the rod to the fully retracted position, so it cannot hold an arbitrary mid-stroke load; use a double-acting MF with an external rod lock for that. Additionally, this non-magnet SKU cannot take a sensor—you need the -S variant for CMSG, DMSG, or EMSG switches.
