Airtac MTF Mini Cylinder MTF40X150SU
The AirTAC Airtac MTF Mini Cylinder MTF40X150SU is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø40mm bore and 150mm 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 MTF40X150SU
Delivering a robust 434.8 N pull force at 0.5 MPa, the AirTAC MTF40X150SU is a JIS-standard round-body mini cylinder engineered for single-acting pull operation. A built-in spring holds the rod extended at rest, while supplying air to the 1/4 inch port retracts it. This fail-safe design automatically drives the rod back out upon air loss, making it ideal for spring-open tasks. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown environments.
Because the quoted pull force is already net of the spring, you can confidently size mechanisms like vertical lifts; with a 2:1 safety margin, this bore pulls or holds about 22.2 kg. The -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG sensors for position detection. Fixed TPU bumper pads absorb end-of-stroke impact across the 50-800 mm/s speed range.

Where the Airtac MTF Mini Cylinder MTF40X150SU Is Used
Heavy-Duty Tensioning
Pulls and holds up to 22.2 kg safely, applying up to 434.8 N of net tension at 0.5 MPa for securing heavy materials during processing.
Spring-Open Diverter
Uses air to retract the 150 mm rod and pull the gate closed; cutting air lets the spring push it out, failing safely to the extended open position.
Washdown Retractor
The SUS304 stainless barrel withstands moist environments, retracting packaging arms or stops up to 645.8 N at 0.7 MPa when pressurized.
Is the Airtac MTF Mini Cylinder MTF40X150SU the Right Cylinder?
When sizing this 40 mm bore, evaluate your tension requirements against both directions: if 434.8 N at 0.5 MPa is excessive, step down to the MTF32 which provides 266.8 N. As the largest available MTF bore, there is no larger standard option. This single-acting pull configuration fits applications needing a return-to-extended fail-safe, such as air-close clamping or tensioning. Ensure your air supply meets the 0.2 MPa minimum floor required to overcome the internal spring. The U flat-end rear cover and 150 mm stroke pair with LB foot, FA flange, SDB pivot, or TC trunnion mounts for versatile installation.
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 MTF40X150SU FAQ
The net pull force is 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 return spring, with a maximum pressure of 1.0 MPa and proof pressure of 1.5 MPa.
The internal spring constantly extends the rod, meaning air is only used to retract it. On air loss, the spring forces the rod fully out; it cannot hold an arbitrary mid-stroke load. The U flat-end rear cover and -S magnet for CMSG/DMSG/EMSG sensors are standard.
