Airtac MTF Mini Cylinder MTF20X30SCM
The AirTAC Airtac MTF Mini Cylinder MTF20X30SCM is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø20mm bore and 30mm 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 MTF20X30SCM
Generating a net pull of 93.4 N at 0.5 MPa (146.1 N at 0.7 MPa), this 20 mm bore JIS-standard round-body mini cylinder is built for tension and fail-safe-open tasks. The MTF20X30SCM uses a single-acting pull mechanism where an internal spring holds the rod extended, and applying air through the 1/8" port retracts it. Because the spring constantly pushes outward, the cylinder naturally drives to the extended position if air pressure drops below the 0.2 MPa floor or is lost entirely.
The SUS304 stainless steel barrel and riveted aluminium covers yield a shorter overall envelope than an ISO 6432 unit of the same bore and stroke, conserving valuable machine space while resisting mild washdown corrosion. This specific configuration includes a CM round-end rear cover and a built-in piston magnet (-S) for position tracking. With a practical safe working load of roughly 56 N, it can reliably hold or vertically lift about 4.8 kg against gravity using a 2:1 safety margin.

| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 93.4 N |

Where the Airtac MTF Mini Cylinder MTF20X30SCM Is Used
Tensioning Systems
Pulls webbing or wire taut with up to 146.1 N of force, releasing the tension instantly when air is applied to retract the 8 mm rod.
Fail-Safe Vent Dampers
Holds a ventilation louver open via spring pressure; air retracts the rod to close the damper, ensuring it fails open during a compressed air outage.
Vertical Load Lowering
Counteracts and pulls down a 4.8 kg vertical load against gravity, using the spring return to safely lift the load when air is removed.
Is the Airtac MTF Mini Cylinder MTF20X30SCM the Right Cylinder?
When sizing this 20 mm bore unit, step up to the MTF25 (153.6 N at 0.5 MPa) if your tensioning load exceeds the 56 N safe working threshold, as no smaller MTF bore exists. The single-acting pull architecture is optimal for spring-open/air-close operations like clamping or gate holding, where losing air must force the mechanism safely outward. Mounting is versatile via LB foot, FA flange, SDB pivot, or TC trunnion brackets, and the integrated -S magnet enables direct CMSG, DMSG, or EMSG sensor mounting without external hardware.
Quick checklist
- ✓ Required force at your working pressure

- ✓ 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 MTF20X30SCM FAQ
This 20 mm bore cylinder provides a net pull force of 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 pressure of 1.0 MPa and a proof pressure of 1.5 MPa.
The internal spring constantly extends the rod, so air must be applied to retract it; on air loss, the rod fails to the fully extended position and will not hold a mid-stroke load. The -S option denotes a built-in magnet compatible with CMSG, DMSG, and EMSG switches, and this unit features a CM round-end cover.
