Airtac MTF Mini Cylinder MTF40X60SCM
The AirTAC Airtac MTF Mini Cylinder MTF40X60SCM 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 MTF40X60SCM
Delivering a substantial 434.8 N of pull at 0.5 MPa, this 40 mm bore pneumatic mini cylinder is engineered for heavy-duty tensioning and air-close operations. The MTF40X60SCM is a JIS-standard round-body unit featuring a SUS304 stainless steel barrel and riveted aluminium covers, offering a shorter overall mounting length than a comparable ISO 6432 cylinder. It operates as a single-acting pull type: an internal spring holds the rod extended at rest, while supplied air retracts it. This fail-safe design ensures the rod drives back out to the extended position if air pressure drops.
The 1/4 inch port and 16 mm rod handle robust cycles, requiring a minimum 0.2 MPa operating pressure to overcome the spring. For practical sizing, the safe working load is roughly 261 N, or it can vertically lift about 22.2 kg with a 2:1 safety margin. This specific configuration includes a CM round-end rear cover and a built-in piston magnet (-S), enabling direct mounting of CMSG, DMSG, or EMSG sensors. End-of-stroke deceleration is handled by fixed TPU bumper pads rather than an adjustable cushion.

Where the Airtac MTF Mini Cylinder MTF40X60SCM Is Used
Heavy Tensioning
Pulls and maintains strong cable or belt tension with up to 434.8 N force, releasing the load only when air is applied.
Fail-Safe Gate Valve
Keeps a heavy industrial valve open via spring force; applying air retracts the 16 mm rod to snap it closed securely.
Vertical Lift Release
Holds a 22 kg payload retracted against gravity using air, relying on the spring to extend and release the load safely upon air loss.
Is the Airtac MTF Mini Cylinder MTF40X60SCM the Right Cylinder?
When selecting this actuator, size both ways against your required tension. If the 434.8 N pull at 0.5 MPa is excessive, step down to the MTF32 bore, which provides 266.8 N at the same pressure; since 40 mm is the largest available MTF bore, moving up is not an option. Choose this single-acting pull model for applications needing spring-open, air-close behavior, or a reliable return-to-extended fail-safe. Ensure your air supply can maintain the 0.2 MPa floor required to retract the rod against the spring. The CM rear cover suits standard rear mounting, and the -S magnet variant supports position sensing.
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 MTF40X60SCM 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 the cylinder fails to the fully extended position upon air loss. It cannot hold an arbitrary mid-stroke load; for that, a double-acting MF cylinder with an external rod lock is required. The SUS304 stainless build resists mild corrosion.
