Airtac MTF Mini Cylinder MTF40X30CA
The AirTAC Airtac MTF Mini Cylinder MTF40X30CA is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø40mm bore and 30mm 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 MTF40X30CA
Delivering a robust 645.8 N of pull at 0.7 MPa, this 40 mm bore single-acting cylinder is built for demanding tension and retraction jobs. It features a JIS-standard round-body design with a SUS304 stainless barrel and riveted aluminium covers, offering a shorter mounting envelope than an ISO 6432 unit of the same size. The CA rear pivot cover simplifies rear-hinge mounting.
Because it is a spring-return pull type, the internal spring holds the rod extended at rest; supplying air to the 1/4 inch port retracts the piston. If air pressure drops, the spring forces the rod back out, yielding a fail-safe-to-extended action. The quoted pull force is already net of the spring, and the design relies on fixed TPU bumper pads for end-of-stroke damping rather than an adjustable cushion. Note that this specific SKU lacks the -S magnet option, so it cannot host CMSG, DMSG, or EMSG sensors.

Where the Airtac MTF Mini Cylinder MTF40X30CA Is Used
Heavy-Duty Tensioning
Uses the 434.8 N pull at 0.5 MPa to draw taut wire or web materials, releasing tension instantly when air is removed and the spring extends.
Fail-Safe Open Valves
Air retracts the rod to close a heavy flap; upon air loss, the internal spring drives the 16 mm rod back out to force the valve open.
Carton Lid Retraction
Pulls a packaging lid clear during product drop, relying on the spring to push the 40 mm piston back to the extended rest position between cycles.
Is the Airtac MTF Mini Cylinder MTF40X30CA the Right Cylinder?
Choose this 40 mm bore when you need substantial pulling muscle; it yields a safe working load of roughly 261 N, or about 22.2 kg of vertical lift with a 2:1 margin. If your load is lighter, step down to the MTF32 which provides 266.8 N of pull at 0.5 MPa. As the largest bore in the MTF family, there is no larger standard size available. Ensure your air supply meets the 0.2 MPa minimum floor required to overcome the spring force. Mounting is versatile with LB foot, FA flange, and TC trunnion options alongside the CA pivot.
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 MTF40X30CA FAQ
This single-acting 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, and uses a 1/4 inch air port.
The spring constantly holds the rod in the extended position; air is required only to pull it in. If air pressure is lost, the spring immediately pushes the rod back out, meaning it fails to the extended state rather than holding a mid-stroke load.
