Airtac MSF Single Acting Mini Cylinder MSF32X50SCM
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF32X50SCM is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø32mm bore and 50mm 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 MSF32X50SCM
Delivering 323.3 N of push force at 0.5 MPa, this 32 mm bore JIS-standard round-body 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 SUS304 stainless steel barrel shrugs off mild corrosion and washdown environments.
The quoted output is already net of the return spring, which sets a 0.2 MPa operating floor. For sizing, this translates to a safe working load of roughly 194 N, or a vertical lift capacity of about 16.5 kg with a 2:1 margin. This -S variant includes a piston magnet for CMSG, DMSG or EMSG sensors, and features a CM round-end rear cover alongside fixed TPU bumper pads for end-of-stroke deceleration.

Where the Airtac MSF Single Acting Mini Cylinder MSF32X50SCM Is Used
Part Ejection
Pushes finished machined components out of a fixture with 323.3 N of force, relying on the spring to safely withdraw the rod when air is cut.
Diverter Gate
Actuates a routing flap on a packaging line, where the single-acting design ensures the gate springs closed to a safe rest position during an outage.
Product Clamping
Secures cardboard cartons or light assemblies during labeling, providing a reliable hold without the plumbing complexity of a double-acting cylinder.
Is the Airtac MSF Single Acting Mini Cylinder MSF32X50SCM the Right Cylinder?
When sizing this unit, compare it directly against the smaller MSF25, which yields 192.8 N at 0.5 MPa, and the larger MSF40, which provides 535.3 N at 0.5 MPa. Choose this 32 mm bore if your clamp, ejector or gate requires that middle-ground force. Remember the 0.2 MPa minimum pressure requirement; below that threshold the internal spring overpowers the air and the rod will not extend.
Mounting options include LB foot, FA flange, SDB pivot and TC trunnion brackets to suit your frame. The -S suffix guarantees the built-in magnet needed for position sensing; a standard SKU without the S cannot accept a reed or electronic switch.
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 MSF32X50SCM FAQ
It generates 323.3 N of push force at 0.5 MPa and 484.1 N at 0.7 MPa. These figures are net of the return spring. The operating pressure ranges from 0.2 to 1.0 MPa, but you must supply at least 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 position; it cannot hold an arbitrary mid-stroke load and should not be used as a controllable brake. For mid-stroke holding you need a double-acting MF cylinder with an external rod lock.
