Airtac MSF Single Acting Mini Cylinder MSF32X20SCM
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF32X20SCM is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø32mm bore and 20mm stroke, 1/4" 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 MSF32X20SCM
Delivering 323.3 N of push force at 0.5 MPa, this AirTAC mini cylinder uses compressed air to extend the rod and an internal spring to retract it. Because it is single-acting, you only plumb one 1/4 inch port, which simplifies valve requirements and ensures the rod fails to the retracted position on air loss. The SUS304 stainless steel barrel shrugs off mild washdown environments.
Built with a JIS-standard riveted round body, the unit is noticeably shorter than an ISO 6432 cylinder of the same bore and stroke, saving valuable mounting length. The fixed TPU bumper pads absorb end-of-stroke impacts across the 50-800 mm/s speed range. Factoring a 2:1 safety margin, this bore achieves a vertical lift capacity of about 16.5 kg, equating to a safe working load of roughly 194 N.

Where the Airtac MSF Single Acting Mini Cylinder MSF32X20SCM Is Used
Spring-Return Clamping
Uses the 323.3 N push output to secure parts during machining, automatically releasing to the safe retracted state if the air supply drops.
Package Ejector
Extends rapidly to push 16.5 kg cartons off a belt, relying on the internal spring to cycle back without needing a secondary exhaust line.
Short-Stroke Gating
Actuates 20 mm diverter gates in washdown zones where the SUS304 stainless barrel prevents mild corrosion and the compact JIS body fits tight frames.
Is the Airtac MSF Single Acting Mini Cylinder MSF32X20SCM the Right Cylinder?
When sizing this unit, compare it directly against the adjacent bores: the MSF25 provides 192.8 N at 0.5 MPa if your load is lighter, while the MSF40 offers 535.3 N for heavier demands. Ensure your supply stays at or above the 0.2 MPa floor, otherwise the return spring will overpower the air pressure and prevent extension. This specific configuration includes the -S magnet for CMSG, DMSG, or EMSG position sensing, and features a CM round-end rear cover for straightforward mounting.
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 MSF32X20SCM FAQ
It generates 323.3 N of push force at 0.5 MPa and 484.1 N at 0.7 MPa. Because these figures are net of the internal spring, you must maintain a minimum operating pressure of 0.2 MPa to overcome the spring and extend the rod.
No. On air loss the spring drives the rod back to the fully retracted position, so it cannot act as a controllable brake or hold an arbitrary mid-stroke load. For held mid-stroke positioning, use a double-acting MF cylinder with an external rod lock.
