Airtac MSF Single Acting Mini Cylinder MSF32X100SU
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF32X100SU is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø32mm bore and 100mm 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 MSF32X100SU
Delivering 323.3 N of push force at 0.5 MPa, this AirTAC MSF32X100SU 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" port, simplifying valve requirements. The quoted force is already net of the return spring, and the unit requires at least 0.2 MPa of pressure to overcome that spring. The SUS304 stainless steel barrel and riveted aluminium covers form a JIS-standard round body that is physically shorter than an equivalent ISO 6432 cylinder, saving valuable mounting length.
For this 32 mm bore with a 100 mm stroke, the safe working load is approximately 194 N (about 60% of the 0.5 MPa rating), which translates to clamping or holding roughly 16.5 kg vertically with a 2:1 safety margin. The rod extends via an M10x1.25 male thread, and fixed TPU bumper pads absorb end-of-stroke impacts across the 50-800 mm/s speed range. This specific configuration includes a flat-end U back cover and a built-in piston magnet (-S), allowing direct mounting of CMSG, DMSG, or EMSG sensors for position confirmation.

Where the Airtac MSF Single Acting Mini Cylinder MSF32X100SU Is Used
Part Ejection
Uses the 323.3 N push force to eject stamped metal components from a die, relying on the spring to safely retract the rod when air is removed.
Pneumatic Clamping
Secures workpieces during machining with a 194 N safe working load, automatically releasing the clamp if the air supply drops.
Divertor Gate
Actuates a routing gate on a packaging line, using the 100 mm stroke to redirect products before spring-returning to the home position.
Is the Airtac MSF Single Acting Mini Cylinder MSF32X100SU the Right Cylinder?
When sizing this 32 mm bore, compare it directly against the adjacent options: the MSF25 provides 192.8 N at 0.5 MPa, while the larger MSF40 offers 535.3 N at 0.5 MPa. Choose this MSF32X100SU when your application requires a moderate push that the 25 mm bore cannot achieve but the 40 mm would overcompensate for. It is ideal for spring-return clamping, ejection, or gating tasks where losing air pressure safely defaults the actuator to its retracted position.
Remember that the 0.2 MPa minimum operating pressure is mandatory to beat the internal spring. This U flat-end rear cover model can be paired with LB foot, FA flange, SDB pivot, or TC trunnion mounts. Because the -S magnet is present, you can freely attach CMSG, DMSG, or EMSG switches without modifying the cylinder.

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 MSF32X100SU FAQ
This 32 mm bore single-acting cylinder generates 323.3 N of push force at 0.5 MPa and 484.1 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring, and utilizes a 1/4" air port.
No, the spring constantly drives the rod to the retracted position on air loss, so it cannot act as a controllable brake or hold a mid-stroke load. For mid-stroke holding, use a double-acting MF cylinder with an external rod lock. This model features a SUS304 stainless barrel and a -S magnet for CMSG/DMSG/EMSG sensors.
