Airtac MSF Single Acting Mini Cylinder MSF32X40SCAT
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF32X40SCAT is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø32mm bore and 40mm 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 MSF32X40SCAT
Delivering 323.3 N of push force at 0.5 MPa (484.1 N at 0.7 MPa), this 32 mm bore pneumatic mini cylinder uses compressed air to extend the rod and an internal spring to retract it. Because it is single-acting, you only need to plumb one 1/4" NPT air line, which simplifies valve requirements and ensures the rod fails safely to the retracted position on air loss. The SUS304 stainless steel barrel shrugs off mild washdown environments.
Built to JIS standards with a riveted round-body construction, the unit is notably 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 model safely lifts or clamps about 16.5 kg vertically, equating to a safe working load of roughly 194 N.

Where the Airtac MSF Single Acting Mini Cylinder MSF32X40SCAT Is Used
Parts Ejection
Uses the 323.3 N push stroke to positively eject stamped metal parts from a die before the spring retracts the rod clear of the tooling.
Package Gating
Actuates a diverter gate on a packaging line; the single-acting spring return guarantees the gate closes to block flow if air pressure drops.
Vertical Lift Stops
Raises a lightweight physical stop to catch totes on a gravity conveyor, securely holding loads up to 16.5 kg before retracting out of the way.
Is the Airtac MSF Single Acting Mini Cylinder MSF32X40SCAT the Right Cylinder?
When sizing this 32 mm bore, compare its 323.3 N @0.5 MPa output against the adjacent options: step down to an MSF25 for 192.8 N, or up to an MSF40 for 535.3 N. This unit is ideal for spring-return clamping, ejecting, or gating tasks. Remember the 0.2 MPa pressure floor; below that, the return spring overpowers the air and the rod will not extend. The included CA pivot back cover suits articulated rod-end loads, and the -S magnet allows tracking with 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 MSF32X40SCAT FAQ
It generates 323.3 N of push force at 0.5 MPa and 484.1 N at 0.7 MPa. Operating pressure must be between 0.2 and 1.0 MPa; 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 rest position, so it cannot hold a mid-stroke load. For mid-stroke holding, use a double-acting MF cylinder with an external rod lock. The -S magnet on this unit enables position sensing with CMSG, DMSG, or EMSG switches.
