Airtac MSF Single Acting Mini Cylinder MSF40X15SCM
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF40X15SCM 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 MSF40X15SCM
Delivering a robust 535.3 N of push force at 0.5 MPa, this AirTAC MSF40X15SCM mini cylinder is built for demanding clamping and ejection tasks. It is a single-acting, push-type actuator with a spring return, meaning compressed air extends the 16 mm rod while an internal spring handles retraction. You only need to plumb a single 1/4 inch port, which simplifies valve setup. Because the quoted force is already net of the return spring, you can confidently apply a safe working load of roughly 321 N or vertically lift about 27.3 kg with a 2:1 safety margin.
The riveted construction pairs a SUS304 stainless steel barrel with aluminium covers, offering excellent resistance to mild corrosion and washdown environments. For the same 40 mm bore and 15 mm stroke, this JIS-standard round body is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length. The rear features a CM round-end cover, and fixed TPU bumper pads absorb end-of-stroke impacts across the 50-800 mm/s speed range.

Where the Airtac MSF Single Acting Mini Cylinder MSF40X15SCM Is Used
Heavy-Duty Clamping
Harness the 535.3 N push force to secure heavy metal workpieces during machining. The spring return automatically releases the clamp if air pressure drops below 0.2 MPa.
Product Ejection
Push finished goods off a conveyor belt rapidly. The single 1/4 inch port keeps pneumatic wiring simple while the fixed TPU bumpers absorb the impact of hard ejections.
Pallet Gating
Actuate heavy pallet stops and diverter gates. The SUS304 stainless barrel withstands dusty industrial environments, and the compact JIS body saves machine space.
Is the Airtac MSF Single Acting Mini Cylinder MSF40X15SCM the Right Cylinder?
When sizing this 40 mm bore actuator, compare its 535.3 N @0.5 MPa output against the next size down: the MSF32 only provides 323.3 N @0.5 MPa, which may be insufficient for heavy pushing. Since 40 mm is the largest available MSF bore, you cannot step up further within this series. Ensure your air supply stays at or above the 0.2 MPa floor; below that threshold, the internal spring overcomes the air pressure and forces the rod back to the retracted rest position. This makes the MSF ideal for fail-safe clamping or ejection, but unsuitable for holding mid-stroke loads on air loss. Mount it using LB foot, FA flange, SDB pivot, or TC trunnion brackets, and note the -S magnet option enables CMSG, DMSG, or EMSG sensors.
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 MSF40X15SCM 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 return spring. The operating pressure range is 0.2-1.0 MPa; you must maintain at least 0.2 MPa to overcome the spring and extend the rod.
No. On air loss the internal spring drives the rod to the fully retracted position, so it cannot hold an arbitrary mid-stroke load. For position holding you need a double-acting MF cylinder with an external rod lock. This MSF40X15SCM includes a -S magnet for position sensing and a CM round-end cover.
