Airtac MTF Mini Cylinder MTF40X10U
The AirTAC Airtac MTF Mini Cylinder MTF40X10U is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø40mm bore and 10mm 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 MTF40X10U
Delivering a robust 434.8 N of pull force at 0.5 MPa, this JIS-standard round-body mini cylinder utilizes a SUS304 stainless barrel and riveted aluminium covers to resist mild corrosion. As a single-acting pull type, an internal spring normally holds the rod extended, while applying air to the 1/4 inch port retracts it. This fail-safe design automatically drives the rod back out upon air loss, making it highly reliable for spring-open applications.
The MTF40X10U features a 40 mm bore, a 16 mm piston rod with an M14x1.5 male thread, and a 10 mm stroke. It provides a safe working load of roughly 261 N, which translates to lifting or holding about 22.2 kg with a 2:1 safety margin. This specific SKU lacks a magnet and therefore cannot host CMSG, DMSG, or EMSG sensors; it also comes with a U flat-end rear cover and relies on fixed TPU bumper pads rather than an adjustable cushion.

Where the Airtac MTF Mini Cylinder MTF40X10U Is Used
Heavy-Duty Tensioning
Uses the 434.8 N pull force to maintain strict tension on cables or belts, releasing the load safely to the extended position if the air supply drops.
Fail-Safe Gate Closing
Holds a heavy barrier open via air retraction, letting the spring force snap it closed securely during a pneumatic power failure.
Product Reject Mechanism
Retracts a 22.2 kg deflector paddle out of the conveyor lane to clear a passing item, then springs back out to isolate the next defective unit.
Is the Airtac MTF Mini Cylinder MTF40X10U the Right Cylinder?
When sizing this 40 mm bore option, evaluate the load both ways: if 434.8 N at 0.5 MPa is excessive, step down to the MTF32 which yields 266.8 N, but since 40 mm is the largest available MTF bore, you cannot size up within this series. A minimum operating pressure of 0.2 MPa is required to overcome the internal spring and initiate the pull stroke. Mounting is versatile with LB foot, FA flange, SDB pivot, or TC trunnion brackets, and remember that because this base SKU has no -S magnet, position sensing is not possible without changing the model.
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 MTF40X10U FAQ
This 40 mm bore 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.
The spring constantly extends the rod, so upon air loss the cylinder fails directly to the fully extended position. It cannot hold a load at an arbitrary mid-stroke point; achieving that would require a double-acting MF cylinder paired with an external rod lock.
