Airtac MSF Single Acting Mini Cylinder MSF40X15CM
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF40X15CM is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø40mm bore and 15mm 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 MSF40X15CM
Delivering a robust 535.3 N of push force at 0.5 MPa, this AirTAC MSF40X15CM mini cylinder is built for demanding short-stroke tasks. As a single-acting push type, compressed air extends the 16 mm rod through a 1/4 inch port, while an internal spring handles the retraction. Because you only plumb one air line, installation is simplified, and the cylinder fails safely to its retracted rest position if air pressure drops. The quoted force is already net of the return spring.
The riveted round-body construction uses a SUS304 stainless steel barrel and aluminium covers, offering excellent resistance to mild corrosion and washdown environments. For the same 40 mm bore and 15 mm stroke, this JIS-standard body is noticeably shorter than an ISO 6432 equivalent, saving valuable machine space. This specific SKU lacks the -S magnet option, so it cannot accept position sensors. It relies on fixed TPU bumper pads for end-of-stroke deceleration. For practical sizing, expect a safe working load around 321 N, or a vertical lift capacity of roughly 27.3 kg with a 2:1 safety margin.

Where the Airtac MSF Single Acting Mini Cylinder MSF40X15CM Is Used
Heavy-Duty Clamping
Use the 535.3 N push output to secure heavy metal workpieces during machining, with the spring ensuring the clamp retracts clear on air loss.
Package Ejection
Ideal for pushing dense products off a conveyor belt over a short 15 mm stroke, relying on the single air line for straightforward cycling.
Short-Stroke Pressing
Apply downward force for seating or light stamping tasks, where the fixed TPU bumper pads quietly absorb the impact at the stroke end.
Is the Airtac MSF Single Acting Mini Cylinder MSF40X15CM the Right Cylinder?
When sizing this 40 mm bore unit, compare it directly against the smaller MSF32, which provides 323.3 N of push at 0.5 MPa. If your application requires less than 323.3 N, step down to the 32 mm bore; if you need maximum push within the series, this 40 mm bore is the largest available, yielding 786.5 N at 0.7 MPa. Remember that a minimum operating pressure of 0.2 MPa is required to overcome the internal return spring. This MSF40X15CM features a CM round-end rear cover and is best matched with LB foot, FA flange, SDB pivot, or TC trunnion mounts. Since this model lacks the -S magnet, it cannot host CMSG, DMSG, or EMSG switches; choose an -S variant if position feedback is required.
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 MSF40X15CM FAQ
This 40 mm bore cylinder provides a push force of 535.3 N at 0.5 MPa and 786.5 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the return spring, with a maximum operating pressure of 1.0 MPa and a proof pressure of 1.5 MPa.
No. On air loss, the spring drives the rod to the retracted position; it cannot hold an arbitrary mid-stroke load. For a held load, use a double-acting MF with an external rod lock. Additionally, this SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.
