Airtac MSF Single Acting Mini Cylinder MSF40X150SCA
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF40X150SCA is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø40mm bore and 150mm 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 MSF40X150SCA
Delivering 535.3 N of push force at 0.5 MPa, this AirTAC MSF40X150SCA mini cylinder is engineered for single-acting push operations. Air extends the Ø16 mm rod, while an internal spring handles the return, meaning you only pipe and valve a single 1/4" port. The quoted force is already net of the return spring, and the unit requires a minimum 0.2 MPa operating pressure to overcome that spring. Built with a SUS304 stainless barrel and riveted aluminium covers, it resists mild corrosion and washdown environments.
As a JIS-standard round-body cylinder, it offers a shorter overall envelope than an ISO 6432 unit for the same 40 mm bore and 150 mm stroke, saving valuable mounting length. It uses fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable cushion. The -S suffix indicates a built-in piston magnet for position sensing, and the CA back cover provides a rear pivot mount. For practical sizing, expect a safe working load of roughly 321 N, or a vertical lift capacity of about 27.3 kg with a 2:1 safety margin.

Where the Airtac MSF Single Acting Mini Cylinder MSF40X150SCA Is Used
Heavy Part Ejection
Uses the full 535.3 N push force at 0.5 MPa to eject dense machined metal components from a fixture, relying on the spring return to reset the plunger automatically.
Pallet Gating
Acts as a heavy-duty stop gate on a conveyor, extending to halt pallets and retracting instantly via the internal spring when air is vented for safe fail operation.
Vertical Lift Stops
Provides positive push positioning for loads up to 27.3 kg vertically, using the CA pivot mount to accommodate slight misalignment during the lift cycle.
Is the Airtac MSF Single Acting Mini Cylinder MSF40X150SCA the Right Cylinder?
When sizing this 40 mm bore model, evaluate your force needs bidirectionally. If 535.3 N at 0.5 MPa is excessive, step down to the MSF32, which provides 323.3 N at the same pressure. Since 40 mm is the largest available bore in this series, exceeding 786.5 N at 0.7 MPa requires a different cylinder family. This single-acting spring-return design is optimal for clamping, ejecting, or gating tasks where the load must fail safely to the retracted position on air loss. Ensure your air supply stays at or above the 0.2 MPa floor so the spring does not overpower the incoming air. The CA pivot cover suits angular movement, and the -S magnet allows CMSG, DMSG, or EMSG switches to track position.
Quick checklist

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 MSF40X150SCA FAQ
This single-acting cylinder generates 535.3 N of push force at 0.5 MPa and 786.5 N at 0.7 MPa. These figures are net of the internal return spring. It requires an operating pressure between 0.2 and 1.0 MPa; the 0.2 MPa floor is necessary to overcome the spring, and it features a 1/4" air port.
No, the internal spring drives the rod to the retracted position on air loss, so it cannot hold an arbitrary mid-stroke load. For mid-stroke holding, use a double-acting MF cylinder with an external rod lock. This model includes the -S magnet for CMSG/DMSG/EMSG sensors and uses fixed TPU bumper pads.
