Airtac MTF Mini Cylinder MTF40X100CA
The AirTAC Airtac MTF Mini Cylinder MTF40X100CA is a genuine single acting, pull (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 MTF Mini Cylinder MTF40X100CA
Delivering a robust 434.8 N of pull force at 0.5 MPa (645.8 N at 0.7 MPa), this JIS-standard round-body mini cylinder is built for heavy-duty tensioning and air-close tasks. The MTF40X100CA uses a SUS304 stainless barrel with riveted aluminium covers, resisting mild corrosion and washdown environments. Because it is a single-acting pull design, an internal spring holds the rod extended at rest; applying air to the 1/4 inch port retracts the 16 mm rod. This fail-safe architecture drives the rod back out upon air loss, making it ideal for spring-open applications. Furthermore, its riveted construction is shorter than a comparable ISO 6432 unit, saving valuable mounting length.
For buyers sizing components, the effective pull at 0.5 MPa translates to roughly 44.3 kgf, yielding a safe vertical lift capacity of about 22.2 kg when applying a 2:1 design margin. This SKU lacks the -S magnet option, meaning it cannot host CMSG, DMSG, or EMSG position sensors. End-of-stroke deceleration is handled by fixed TPU bumper pads rather than an adjustable air cushion. The unit includes a CA rear pivot cover and operates reliably between 0.2 and 1.0 MPa, requiring the 0.2 MPa minimum floor just to overcome the return spring.

Where the Airtac MTF Mini Cylinder MTF40X100CA Is Used
Fail-Safe Vent Opening
Uses the 434.8 N spring force to mechanically hold a vent or door open, applying air only to pull it closed during emergencies.
Heavy Tensioning
Maintains constant pulling tension on cables or webbing, relying on the spring to keep the 16 mm rod extended against the load.
Clamp Retraction
Pulls a 22.2 kg workpiece clamp back to a safe extended rest position automatically when pneumatic pressure is removed.
Is the Airtac MTF Mini Cylinder MTF40X100CA the Right Cylinder?
When specifying this 40 mm bore model, sizing both ways ensures optimal performance. If 434.8 N of pull at 0.5 MPa is excessive for your application, stepping down to the MTF32 provides 266.8 N, while the MTF40 remains the largest available bore in the series with a maximum standard stroke of 150 mm. Choose this single-acting pull configuration when the mechanism must fail to the extended position on air loss, such as in emergency vent or tensioning systems. Ensure your air supply meets the 0.2 MPa floor required to beat the internal spring. Mounting is versatile via the CA back cover, and because this specific SKU omits the -S magnet, you must select a magnet-equipped variant if CMSG, DMSG, or EMSG sensing is required.
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 MTF40X100CA FAQ
This 40 mm bore cylinder generates 434.8 N of pull force 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 and a proof pressure of 1.5 MPa. The 1/4 inch port drives the 16 mm rod.
The spring constantly drives the rod to the extended position, so upon air loss the cylinder fails to the extended state. It cannot hold an arbitrary mid-stroke load; for that you need a double-acting MF cylinder with an external rod lock. Note this non-S SKU cannot take magnetic sensors, and the SUS304 body uses fixed TPU bumpers instead of adjustable cushions.
