Airtac MSF Single Acting Mini Cylinder MSF40X15CA
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF40X15CA 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 MSF40X15CA
Delivering 535.3 N of push force at 0.5 MPa, this AirTAC MSF40X15CA mini cylinder uses air to extend the rod and an internal spring to retract it, requiring only a single 1/4" air line. Because it is a single-acting push type, it fails safely to the retracted position on air loss and cannot be loaded on the return stroke. The 40 mm bore generates a vertical lift capacity of about 27.3 kg with a 2:1 margin.
Built as a JIS-standard round-body unit with a SUS304 stainless barrel and riveted aluminium covers, it offers a shorter mounting envelope than an ISO 6432 cylinder for the same stroke. This specific SKU lacks a magnet, so it cannot accept CMSG, DMSG or EMSG sensors; adding the -S option enables switch readiness. Deceleration is handled by fixed TPU bumper pads rather than an adjustable cushion.

Where the Airtac MSF Single Acting Mini Cylinder MSF40X15CA Is Used
Heavy Part Ejection
Uses the 535.3 N push force to positively eject dense machined metal components from a fixture, returning automatically via spring when air is cut.
Gate Diversion
Actuates a heavy diverter arm on a packaging line, relying on the 40 mm bore power to push products onto a secondary track.
Pallet Stopping
Functions as a robust pallet stopper where the spring-return design guarantees the barrier retracts clear of the conveyor path during an air loss event.
Is the Airtac MSF Single Acting Mini Cylinder MSF40X15CA the Right Cylinder?
For lighter ejection tasks, step down to the MSF32 which provides 323.3 N of push at 0.5 MPa, as the MSF40 is the largest bore available in this series. Ensure your supply meets the 0.2 MPa minimum operating pressure required to overcome the return spring. This CA pivot back cover suits angular alignment, and you can pair it with LB foot or FA flange front mounts. Since this base model has no magnet, order an -S variant if you need 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 MSF40X15CA FAQ
It generates 535.3 N of push force at 0.5 MPa and 786.5 N at 0.7 MPa. The operating pressure range is 0.2 to 1.0 MPa; a minimum of 0.2 MPa is required to overcome the internal return spring.
No, this specific SKU does not include a magnet and cannot accept CMSG, DMSG or EMSG switches. You must select the -S magnet option to enable sensing. The CA back cover provides a pivot mount.
