Airtac MTF Mini Cylinder MTF20X75CM
The AirTAC Airtac MTF Mini Cylinder MTF20X75CM is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø20mm bore and 75mm stroke, 1/8" 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 MTF20X75CM
Delivering a net pull force of 93.4 N at 0.5 MPa, this JIS-standard round-body mini cylinder is built for single-acting pull operations. The internal spring actively extends the 8 mm rod, while supplying air to the 1/8" port retracts it. Because it fails to the extended position on air loss, it is ideal for spring-open, air-close jobs. The SUS304 stainless barrel and riveted aluminium covers resist mild washdown environments.
For the same 20 mm bore and 75 mm stroke, this riveted construction is shorter than an ISO 6432 cylinder, saving valuable mounting length. It uses fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable cushion. Without the -S magnet option, this specific SKU cannot host CMSG, DMSG, or EMSG sensors. Based on the 0.5 MPa rating, the safe working load is roughly 56 N, which translates to lifting or holding about 4.8 kg vertically with a 2:1 safety margin.

Where the Airtac MTF Mini Cylinder MTF20X75CM Is Used
Fail-Safe Gate Opening
Use the spring-extended rest position to automatically push a guard gate open when air pressure drops, ensuring safe machine access.
Light Tensioning
Apply the 93.4 N pull force at 0.5 MPa to maintain steady tension on light packaging films or wire feeds during production cycles.
Spring-Return Retraction
Pull a small diverter or stopper pin out of the way with air, letting the internal spring snap it back into the blocking position.
Is the Airtac MTF Mini Cylinder MTF20X75CM the Right Cylinder?
When sizing this 20 mm bore unit, step up to the MTF25 if you need more strength, as it provides 153.6 N of pull at 0.5 MPa. There is no smaller MTF bore, making this the baseline option for light tensioning. Choose this single-acting pull configuration when a mechanism must return to an extended state automatically, such as a fail-safe gate. Ensure your air supply meets the 0.2 MPa minimum floor required to overcome the spring. The CM round-end back cover suits direct mounting, and you can pair it with LB foot or FA flange brackets.
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 MTF20X75CM FAQ
The net pull force is 93.4 N at 0.5 MPa and 146.1 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the return spring, with a maximum of 1.0 MPa and proof pressure of 1.5 MPa.
No, this specific SKU lacks the internal magnet. You must select the -S variant to use CMSG, DMSG, or EMSG magnetic switches. Additionally, the spring extends the rod on air loss, so it fails to the extended position rather than holding a mid-stroke load.
