Airtac MTF Mini Cylinder MTF20X75SCA
The AirTAC Airtac MTF Mini Cylinder MTF20X75SCA 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 MTF20X75SCA
Generating 93.4 N of pull at 0.5 MPa, the AirTAC MTF20X75SCA is a JIS-standard round-body mini cylinder built for single-acting tension and return-to-extended tasks. An internal spring holds the rod out, while supplying air to the 1/8" port retracts it. This fail-safe behavior ensures the rod drives outward if air pressure drops. The SUS304 stainless barrel and riveted aluminium covers resist mild washdown environments, and the body is notably shorter than an ISO 6432 unit of the same bore and stroke.
This 20 mm bore model features an 8 mm rod with an M8x1.25 male thread, yielding a safe working load of roughly 56 N. It includes the -S magnet for CMSG, DMSG, or EMSG switches, and uses fixed TPU bumper pads for end-of-stroke deceleration across its 75 mm travel. The CA rear pivot cover simplifies angular mounting, and a minimum of 0.2 MPa is required to overcome the spring.

Where the Airtac MTF Mini Cylinder MTF20X75SCA Is Used
Tension Control
Pulls light filaments or belts with a safe working load near 56 N, releasing tension instantly when air is removed.
Fail-Safe Gates
Holds access doors open via spring force; applying air to the 1/8" port retracts the rod to let the gate close securely.
Light Clamping
Retracts a 75 mm stroke pin to clear a workspace, relying on the spring to drive the pin back out and lock the part.
Is the Airtac MTF Mini Cylinder MTF20X75SCA the Right Cylinder?
When sizing this 20 mm bore option, step up to the MTF25 if you need more force, as it provides 153.6 N of pull at 0.5 MPa. Since 20 mm is the smallest available MTF bore, there is no smaller variant to step down to. The 0.2 MPa pressure floor must be met to retract the rod against the spring.
This pull configuration fits spring-open, air-close mechanisms like tensioning or clamping. For mounting, pair the CA back cover with LB foot, FA flange, SDB pivot, or TC trunnion brackets. The included -S piston magnet enables position sensing with CMSG, DMSG, or EMSG switches.

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 MTF20X75SCA 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 internal spring and retract the rod.
The spring constantly extends the rod, so an air loss drives the cylinder to the fully extended position. It cannot hold a mid-stroke load; use a double-acting MF with an external rod lock for that. The -S magnet allows CMSG or DMSG sensors to track this extended state.
