Airtac MSF Single Acting Mini Cylinder MSF40X60CM
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF40X60CM 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 MSF40X60CM
Delivering 535.3 N of push force at 0.5 MPa, this AirTAC MSF40X60CM 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. The MSF series features a JIS-standard round-body design with a SUS304 stainless barrel and riveted aluminium covers, offering a shorter mounting envelope than an ISO 6432 unit of the same bore and stroke. A CM round-end back cover equips this specific model.
The quoted output is already net of the return spring, meaning it cannot be loaded on the retract stroke. For sizing, this translates to a safe working load of about 321 N, or a vertical lift capacity of roughly 27.3 kg with a 2:1 safety margin. It relies on fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable cushion. Note that this SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors without switching to an -S variant.

Where the Airtac MSF Single Acting Mini Cylinder MSF40X60CM Is Used
Heavy Duty Clamping
Provides 535.3 N of push force at 0.5 MPa to secure heavy workpieces, automatically releasing them when air pressure is removed.
Part Ejection
Uses its robust extension force to push finished components off a line, with the internal spring ensuring a fail-safe retracted rest state.
Vertical Lift Gates
Raises diverters or gates weighing up to 27.3 kg with a 2:1 margin, relying on gravity and the return spring to close when air drops.
Is the Airtac MSF Single Acting Mini Cylinder MSF40X60CM the Right Cylinder?
Choose this 40 mm bore when you need heavy clamping or ejecting force, stepping up from the MSF32 which provides 323.3 N at 0.5 MPa; there is no larger MSF bore available. It is ideal for operations like spring-return gating where air loss safely drives the rod back to its retracted position. Ensure your supply stays at or above the 0.2 MPa floor, otherwise the spring will overpower the air and prevent extension. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion, but remember this non-magnetic version cannot support position sensing.
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 MSF40X60CM FAQ
It generates 535.3 N of push force at 0.5 MPa and 786.5 N at 0.7 MPa. Because it is single-acting with a spring return, the operating pressure must remain between 0.2 and 1.0 MPa; below 0.2 MPa the spring wins and the rod will not extend.
No, this specific SKU does not include a magnet, so it cannot host CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. Also, the internal spring only drives the rod to the retracted position on air loss; it will not hold a mid-stroke load.
