Airtac MSF Single Acting Mini Cylinder MSF32X150U
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF32X150U 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 MSF32X150U
Delivering 323.3 N of push force at 0.5 MPa (484.1 N at 0.7 MPa), this 32 mm bore cylinder uses air to extend the rod and an internal spring to retract it. Because it is single-acting, you only pipe and valve one 1/4" port, simplifying automation. The quoted force is already net of the return spring. The SUS304 stainless round body and riveted aluminium covers yield a shorter mounting envelope than an ISO 6432 unit of identical size, while resisting mild washdown corrosion. This U-cover variant features a flat rear end. It uses fixed TPU bumper pads for end-of-stroke deceleration across its 150 mm travel.
For practical sizing, expect a safe working load around 194 N (roughly 60% of the 0.5 MPa rating). Vertically, it can lift or clamp about 16.5 kg with a 2:1 safety margin. Operating pressure must stay at or above 0.2 MPa so the air overcomes the spring. Note this SKU lacks a magnet, so it cannot host CMSG, DMSG, or EMSG sensors; specify the -S version if you need position detection.

Where the Airtac MSF Single Acting Mini Cylinder MSF32X150U Is Used
Part Ejection
Uses the full 150 mm stroke to push machined parts out of a fixture, relying on the internal spring to safely withdraw the rod when air is cut.
Pneumatic Clamping
Applies up to 323.3 N of holding force at 0.5 MPa to secure workpieces, automatically releasing to the retracted position during an air pressure drop.
Flow Gating
Actuates as a diverter gate on a packaging line, where the single 1/4 inch port simplifies valve plumbing and the SUS304 barrel resists splashing.
Is the Airtac MSF Single Acting Mini Cylinder MSF32X150U the Right Cylinder?
If 323.3 N at 0.5 MPa is too much, step down to the MSF25 which provides 192.8 N; if you need more thrust, the MSF40 offers 535.3 N. This 150 mm stroke is the maximum standard length for the series. Single-acting push logic is ideal for clamping, ejecting, or gating tasks where the spring safely retracts the rod on air loss. Ensure your supply meets the 0.2 MPa floor to beat the spring. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion brackets, and you can pair them with the U, CA, or CM back covers.
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 MSF32X150U FAQ
It generates 323.3 N of thrust at 0.5 MPa and 484.1 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.
No, this specific SKU does not include a magnet, so it cannot support CMSG, DMSG, or EMSG switches. You would need the -S variant for position sensing. Also, the spring returns the rod on air loss but cannot hold a mid-stroke load; use a double-acting MF with a rod lock for that.
