Airtac MTF Mini Cylinder MTF40X100SU
The AirTAC Airtac MTF Mini Cylinder MTF40X100SU 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 MTF40X100SU
Delivering a robust 434.8 N of net pull force at 0.5 MPa, this JIS-standard round-body mini cylinder is engineered for heavy-duty tensioning and air-close operations. The SUS304 stainless barrel and riveted aluminium covers form a compact assembly that is physically shorter than a comparable ISO 6432 unit, saving valuable mounting length. Because it is a single-acting pull type, an internal spring holds the 16 mm rod extended at rest, while supplying 1/4 inch port air retracts it against the load.
With a safe working load around 261 N (roughly 60 percent of the 0.5 MPa rating), it can vertically lift or hold about 22.2 kg with a 2:1 safety margin. The fixed TPU bumper pads absorb end-of-stroke impacts across the 100 mm travel. Furthermore, this SU variant includes a built-in piston magnet for position sensing and uses a U flat-end rear cover to flush-mount against machine frames.

Where the Airtac MTF Mini Cylinder MTF40X100SU Is Used
Heavy-Duty Tensioning
Pulls and maintains 22.2 kg of tension with a 2:1 safety margin, ideal for keeping drive belts or cables taut during operation.
Fail-Safe Gate Closing
Uses air to pull the gate open, while the internal spring automatically drives the rod back out to securely close the barrier upon air loss.
Carton Retraction
Leverages the 434.8 N pull force to retract heavy packaging flaps or holding arms out of the way after a sealing cycle completes.
Is the Airtac MTF Mini Cylinder MTF40X100SU the Right Cylinder?
When sizing this 40 mm bore unit, compare its 434.8 N pull at 0.5 MPa against the next size down: an MTF32 provides 266.8 N, which may be insufficient for high-tension closing tasks. As 40 mm is the largest available MTF bore, exceeding this capacity requires a different cylinder family entirely. This single-acting pull design fits applications needing a spring-open, air-close cycle, provided the system maintains at least the 0.2 MPa pressure floor required to overcome the return spring.
Mounting flexibility is offered through LB foot, FA flange, SDB pivot, and TC trunnion brackets. The included -S magnet enables CMSG, DMSG, and EMSG electronic or reed switches for precise end-position detection.
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 MTF40X100SU FAQ
This single-acting pull cylinder generates 434.8 N of net 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 spring, with a maximum pressure of 1.0 MPa and a proof pressure of 1.5 MPa. Air is supplied to the 1/4 inch port to retract the rod.
If air pressure is lost, the internal spring immediately drives the rod to the fully extended position, meaning it fails safe to the open state rather than holding a mid-stroke load. The -S magnet in this unit allows CMSG, DMSG, or EMSG sensors to confirm that extended position.
