Airtac MSF Single Acting Mini Cylinder MSF40X100CA
The AirTAC Airtac MSF Single Acting Mini Cylinder MSF40X100CA is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø40mm bore and 100mm 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 MSF40X100CA
Delivering 535.3 N of push force at 0.5 MPa and 786.5 N at 0.7 MPa, this 40 mm bore mini cylinder uses compressed air to extend the rod and an internal spring to retract it. Because it is single-acting, you only need to plumb one 1/4 inch port, simplifying valve requirements. The quoted forces are already net of the return spring, and the unit requires at least 0.2 MPa of operating pressure to overcome that spring. For practical sizing, expect a safe working load of about 321 N, which translates to clamping or vertically lifting roughly 27.3 kg with a 2:1 safety margin.
Built as a JIS-standard round-body unit with a SUS304 stainless steel barrel and riveted aluminium covers, it offers a shorter mounting envelope than an ISO 6432 cylinder of the same bore and stroke. This specific configuration features a 100 mm stroke, an M14x1.5 male rod thread, fixed TPU bumper pads for end-of-stroke deceleration, and a CA rear pivot cover. Note that this SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG position switches without upgrading to an -S variant.

Where the Airtac MSF Single Acting Mini Cylinder MSF40X100CA Is Used
Heavy Duty Clamping
Secures heavy metal workpieces during machining, using its 535.3 N push force to hold approximately 27.3 kg firmly against a fixture.
Part Ejection
Pushes finished components off a conveyor belt with a 100 mm stroke, relying on the internal spring to safely withdraw the pin when air is removed.
Pallet Gating
Acts as a spring-return stop gate on a roller conveyor, extending to halt pallet flow and instantly retracting to release goods upon air release.
Is the Airtac MSF Single Acting Mini Cylinder MSF40X100CA the Right Cylinder?
When sizing this 40 mm bore model, verify your motion requirements both ways: stepping down to the MSF32 drops the 0.5 MPa push force to 323.3 N, while no larger MSF bore exists above 40 mm. This single-acting push design is ideal for simple clamping, ejecting, or gating tasks where the spring automatically retracts the rod on air loss. Remember the 0.2 MPa pressure floor; below this, the internal spring wins and the rod will not extend. Mounting is versatile via the CA pivot cover, and because this specific unit has no -S magnet, external mechanical stops or limit sensors are required for position confirmation.
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 MSF40X100CA FAQ
This 40 mm bore cylinder provides a net push force of 535.3 N at 0.5 MPa and 786.5 N at 0.7 MPa. It requires an operating pressure between 0.2 and 1.0 MPa, with the 0.2 MPa minimum strictly necessary to overcome the internal return spring.
No. On air loss, the spring drives the rod to the fully retracted position; it cannot hold an arbitrary mid-stroke load. Additionally, this specific SKU lacks a magnet, so it cannot support CMSG, DMSG, or EMSG switches. For mid-stroke holding, use a double-acting MF cylinder with an external rod lock.
