Airtac MSF Single Acting Mini Cylinder MSF32X75U
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF32X75U is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø32mm bore and 75mm 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 MSF32X75U
Delivering 323.3 N of push force at 0.5 MPa (484.1 N at 0.7 MPa), this 32 mm bore, 75 mm stroke 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 MSF32X75U features a JIS-standard round-body design with a SUS304 stainless steel barrel and riveted aluminium covers, offering a shorter mounting envelope than an ISO 6432 cylinder of the same size while resisting mild washdown corrosion.
The quoted push force is already net of the return spring, and the unit requires a minimum 0.2 MPa operating pressure to overcome that spring. It uses fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable cushion. This specific SKU lacks a magnet and cannot accept position sensors; adding the -S option enables CMSG, DMSG, or EMSG switches. For practical sizing, expect a safe working load around 194 N, or roughly 16.5 kg of vertical lift with a 2:1 safety margin.

Where the Airtac MSF Single Acting Mini Cylinder MSF32X75U Is Used
Part Ejection
Uses the 323.3 N push force to eject finished parts from a machining fixture, with the spring safely pulling the rod back on air release.
Spring-Return Clamping
Holds workpieces securely during light machining, automatically releasing and retracting if the air supply drops below the 0.2 MPa floor.
Flow Gating
Actuates a diverter gate on a packaging line, using the 1/4" single air line to push the gate open and the internal spring to close it.
Is the Airtac MSF Single Acting Mini Cylinder MSF32X75U the Right Cylinder?
When sizing this 32 mm bore model, compare it directly with adjacent bores: the MSF25 provides 192.8 N at 0.5 MPa, while the MSF40 offers 535.3 N at 0.5 MPa. Choose this 32 mm option when your application requires a solid push but falls below the threshold needing the larger 40 mm body. It excels in single-acting tasks like spring-return clamping, part ejection, or gating, where losing air pressure safely drives the rod back to its retracted rest position.
This cylinder operates between 0.2 and 1.0 MPa and runs at 50-800 mm/s. The U flat-end back cover provides a standard mounting surface, and you can pair it with LB foot, FA flange, SDB pivot, or TC trunnion brackets. Remember that without the -S magnet option, this cylinder cannot support sensing switches, so confirm if your control system requires position feedback before ordering.
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 MSF32X75U FAQ
This 32 mm bore cylinder provides a net push force of 323.3 N 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 extend the rod.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need to specify the -S variant for position sensing. It also uses fixed TPU bumper pads instead of an adjustable air cushion.
