Airtac MSF Single Acting Mini Cylinder MSF32X150SCM
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF32X150SCM is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø32mm bore and 150mm 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 MSF32X150SCM
Delivering 323.3 N of push force at 0.5 MPa, this AirTAC MSF32X150SCM mini cylinder uses air to extend the rod and an internal spring to retract it. Because it is single-acting, you only plumb one 1/4" port, simplifying valve requirements while ensuring the rod fails to the retracted position on air loss. The 150 mm stroke hits the maximum standard limit for this JIS-standard round-body design.
Built with a SUS304 stainless steel barrel and riveted aluminium covers, the riveted construction is shorter than a comparable ISO 6432 cylinder, saving valuable mounting length. The fixed TPU bumper pads absorb end-of-stroke impacts without needing adjustment. Factoring a 60% safety margin, the safe working load is roughly 194 N, capable of vertically lifting about 16.5 kg with a 2:1 ratio.

Where the Airtac MSF Single Acting Mini Cylinder MSF32X150SCM Is Used
Part Ejection
Uses the 323.3 N push output to positively eject stamped parts from a die, with the spring safely pulling the rod back clear of the tooling on air release.
Diversion Gate
Extends 150 mm to push a routing flap across a conveyor belt, relying on the single-acting spring return to retract the gate when air is removed.
Carton Stopping
Acts as a sturdy stopper for medium-weight packaging lines, applying up to 484.1 N at 0.7 MPa to halt items before the spring retracts the stop clear.
Is the Airtac MSF Single Acting Mini Cylinder MSF32X150SCM the Right Cylinder?
When sizing this 32 mm bore, compare its 323.3 N @0.5 MPa output against the smaller MSF25 at 192.8 N or the larger MSF40 at 535.3 N. This model fits spring-return clamping or ejecting tasks perfectly, but remember the working pressure floor is 0.2 MPa—below that, the return spring wins and the rod will not extend fully. The included -S magnet enables CMSG, DMSG or EMSG position sensing, and the CM round-end back cover suits compact rear pivot 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 MSF32X150SCM FAQ
The single-acting push force is 323.3 N at 0.5 MPa and 484.1 N at 0.7 MPa, already net of the return spring. It requires a minimum operating pressure of 0.2 MPa to overcome the spring and extend the rod.
No. On air loss, the internal spring drives the rod to the fully retracted rest position; it cannot hold an arbitrary mid-stroke load. For mid-stroke holding, use a double-acting MF cylinder with an external rod lock. The -S magnet allows CMSG/DMSG/EMSG sensors to track end positions.
