Airtac MTF Mini Cylinder MTF40X150CA
The AirTAC Airtac MTF Mini Cylinder MTF40X150CA is a genuine single acting, pull (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 MTF Mini Cylinder MTF40X150CA
Delivering 434.8 N of net pull force at 0.5 MPa, this AirTAC MTF40X150CA handles the heaviest tensioning jobs in the mini cylinder range. It is a JIS-standard round-body unit with a SUS304 stainless barrel and riveted aluminium covers, engineered specifically for single-acting pull operation. An internal spring holds the rod extended at rest, while applying air to the 1/4 inch port retracts it. Because the spring drives the rod out upon air loss, the cylinder inherently fails to the extended position.
The riveted construction is shorter than a comparable ISO 6432 cylinder, saving valuable machine space without sacrificing the full 150 mm stroke. End-of-travel impact is absorbed by fixed TPU bumper pads rather than an adjustable cushion. For practical sizing, the 434.8 N pull at 0.5 MPa yields a safe working load of roughly 261 N, or about 22.2 kg of vertical lift with a 2:1 margin. Note that this specific SKU lacks the -S magnet, so it cannot support CMSG, DMSG, or EMSG sensors.

Where the Airtac MTF Mini Cylinder MTF40X150CA Is Used
Heavy-Duty Tensioning
Pulls cables or heavy levers with 434.8 N at 0.5 MPa, releasing the tension only when compressed air is applied to retract the rod.
Fail-Safe Open Valves
Keeps a large process valve open via spring force. Air retracts the mechanism to close it, ensuring the valve automatically opens if the air supply drops.
Vertical Load Retraction
Lifts and holds loads up to 22.2 kg against gravity during operation, using air to pull the weight downward before the spring pushes it back out.
Is the Airtac MTF Mini Cylinder MTF40X150CA the Right Cylinder?
When sizing this 40 mm bore, compare its 434.8 N pull at 0.5 MPa against the next size down: the MTF32 provides 266.8 N, making this model necessary when overcoming heavier return springs or pulling substantial loads. As the largest bore in the series, there is no larger MTF to step up to. It requires a minimum operating pressure of 0.2 MPa to overcome the internal spring and begin the retract stroke, with a maximum limit of 1.0 MPa.
This model includes a CA rear pivot cover, ideal for applications requiring angular alignment. If your mechanism needs position feedback, you must select the -S magnet variant to enable CMSG, DMSG, or EMSG switches. Remember that the spring only drives the rod to the extended rest position; it will not hold a load at mid-stroke.
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 MTF Mini Cylinder MTF40X150CA FAQ
This single-acting pull cylinder provides a net pull force of 434.8 N at 0.5 MPa and 645.8 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring, with a maximum pressure limit of 1.0 MPa.
No, this specific SKU does not include a magnet. You must select the -S variant to use CMSG, DMSG, or EMSG sensors. Additionally, the spring extends the rod at rest and upon air loss, meaning it fails to the extended position and cannot hold a mid-stroke load.
