Airtac MTF Mini Cylinder MTF40X60SU
The AirTAC Airtac MTF Mini Cylinder MTF40X60SU is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø40mm bore and 60mm 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 MTF40X60SU
Delivering a robust 434.8 N of net pull at 0.5 MPa, the AirTAC MTF40X60SU is built for heavy-duty tensioning and air-close operations. This JIS-standard round-body mini cylinder utilizes a SUS304 stainless barrel with riveted aluminium covers, resisting mild corrosion and washdown environments. Because it is a single-acting pull type, an internal spring holds the piston rod normally extended, and supplying air to the 1/4 inch port retracts it. The compact riveted body is notably shorter than an ISO 6432 cylinder of the same bore and stroke, saving valuable machine space.
The integrated -S piston magnet enables position tracking with CMSG, DMSG, or EMSG switches. With a 16 mm rod and M14x1.5 male thread, it handles substantial loads; a practical safe working load is roughly 261 N, or about 22.2 kg of vertical lift with a 2:1 safety margin. End-of-stroke deceleration relies on fixed TPU bumper pads, and the U flat-end back cover simplifies direct rear mounting. If air pressure drops below the 0.2 MPa floor or is lost entirely, the spring automatically drives the rod back out to the extended fail-safe position.

Where the Airtac MTF Mini Cylinder MTF40X60SU Is Used
Heavy Tensioning
Pulls and maintains tension on cables or webbing with up to 434.8 N force, automatically snapping back to the extended position if air pressure is lost.
Fail-Safe Gate Control
Holds a heavy guard door open via spring force, using 1/4 inch port air to pull it closed securely during machine run cycles.
Vertical Retraction
Lifts and holds items weighing roughly 22 kg against gravity using a 2:1 safety margin, relying on the 16 mm rod for stable vertical pulling.
Is the Airtac MTF Mini Cylinder MTF40X60SU the Right Cylinder?
When sizing this 40 mm bore unit against the MTF family, stepping down to the MTF32 provides 266.8 N of pull at 0.5 MPa, whereas the MTF40X60SU is the largest available bore offering 434.8 N at that same pressure. Choose this single-acting pull configuration for mechanisms requiring a spring-open, air-close action, such as tensioning or fail-safe-open gates. Ensure your air supply meets the 0.2 MPa minimum to overcome the internal spring. Mounting flexibility is extensive: pair the U flat-end back cover with LB foot, FA flange, SDB pivot, or TC trunnion brackets, and utilize the built-in magnet for electronic sensor feedback.
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 MTF40X60SU 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 and retract the rod.
The internal spring constantly extends the rod, meaning a loss of air pressure forces the cylinder to its extended rest position rather than holding a mid-stroke load. This specific unit features a U flat-end back cover and includes a built-in magnet for CMSG, DMSG, or EMSG sensors.
