Airtac MSF Single Acting Mini Cylinder MSF40X60SU
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF40X60SU is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø40mm bore and 60mm 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 MSF40X60SU
Delivering a robust 535.3 N of push force at 0.5 MPa, this AirTAC MSF40X60SU mini cylinder is built for single-acting push operations where air extends the rod and an internal spring handles the retraction. Because you only pipe and valve a single 1/4 inch port, plumbing is simplified, and the unit fails safely to the retracted position upon air loss. The quoted force is already net of the return spring, requiring a minimum 0.2 MPa operating pressure to overcome it.
The riveted rolling-packed construction features a SUS304 stainless steel barrel and aluminium covers, offering excellent resistance to mild corrosion and washdown environments. For the same 40 mm bore and 60 mm stroke, this JIS-standard round body is notably shorter than an ISO 6432 cylinder, saving valuable mounting length. The U flat-end back cover provides a clean rear profile, and the included -S magnet enables position sensing. With a practical safe working load of roughly 321 N, it can vertically lift or clamp about 27.3 kg with a 2:1 safety margin.

Where the Airtac MSF Single Acting Mini Cylinder MSF40X60SU Is Used
Heavy-Duty Clamping
Use the 535.3 N push force to secure heavy workpieces during machining, relying on the spring return to release the part automatically when air is removed.
Package Ejector
Push heavy cartons off a conveyor belt efficiently; the single 1/4 inch port keeps valve requirements minimal for high-cycle ejection gates.
Vertical Lift Gate
Lift or hold a material handling gate weighing up to 27.3 kg with a 2:1 safety margin, trusting the spring to safely lower the gate on air loss.
Is the Airtac MSF Single Acting Mini Cylinder MSF40X60SU the Right Cylinder?
When sizing this 40 mm bore, evaluate your load against the 535.3 N push force at 0.5 MPa. If your application requires less effort, the smaller MSF32 provides 323.3 N at the same pressure; since 40 mm is the largest available MSF bore, you cannot step up further within this series. This single-acting spring-return design is ideal for clamping, ejecting, or gating tasks where the load cannot be driven on the return stroke. Keep the operating pressure at or above the 0.2 MPa floor so the air reliably beats the spring. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion, while the built-in -S magnet supports CMSG, DMSG, and EMSG switches.
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 MSF40X60SU FAQ
This 40 mm bore cylinder provides a single-acting push force of 535.3 N at 0.5 MPa and 786.5 N at 0.7 MPa. These figures are net of the internal return spring. You must supply at least 0.2 MPa of operating pressure to overcome the spring and extend the rod.
No. On air loss, the internal spring drives the rod to the fully retracted rest position, meaning it cannot hold an arbitrary mid-stroke load. For held mid-stroke loads, use a double-acting MF cylinder with an external rod lock. The -S magnet on this unit allows CMSG, DMSG, and EMSG sensors to detect end-of-stroke positions.
