Airtac MTF Mini Cylinder MTF20X10SU
The AirTAC Airtac MTF Mini Cylinder MTF20X10SU is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø20mm bore and 10mm 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 MTF20X10SU
Delivering a net pull of 93.4 N at 0.5 MPa, this JIS-standard round-body mini cylinder uses an internal spring to keep the rod extended and compressed air to retract it. The SUS304 stainless barrel and riveted aluminium covers yield a shorter mounting envelope than an ISO 6432 unit of the same 20 mm bore and 10 mm stroke, while resisting mild washdown corrosion. Because the spring holds the rod out, the cylinder fails safely to the extended position if air pressure drops below the 0.2 MPa floor.
The 1/8" port and M8x1.25 male rod thread keep the pneumatic plumbing compact. With a safe working load of roughly 56 N (about 60 percent of the 0.5 MPa pull), it is ideal for light tensioning or spring-open tasks. This -S variant includes a built-in piston magnet for CMSG, DMSG or EMSG switches, and the U flat-end back cover suits tight rear-mounting spaces. Fixed TPU bumper pads absorb end-of-stroke impact across the 50-800 mm/s speed range.

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

Where the Airtac MTF Mini Cylinder MTF20X10SU Is Used
Light Tensioning
Pulls small cables or webs with a 56 N safe working load, releasing tension instantly when air is applied.
Spring-Open Gate
Holds a small access flap closed via air pressure; the spring automatically extends the rod to open the gate on air loss.
Reject Arm Retract
Uses the 10 mm stroke to retract a tiny diverter pin, relying on the spring to push the arm back out for the next cycle.
Is the Airtac MTF Mini Cylinder MTF20X10SU the Right Cylinder?
Choose this 20 mm bore when a short 10 mm stroke and a 93.4 N pull at 0.5 MPa meet your tensioning requirement. If the load demands less force, note that MTF is the smallest available bore in the series. If you need more pull, step up to the MTF25, which provides 153.6 N at 0.5 MPa. The single-acting pull action fits air-close, spring-open circuits perfectly, but remember the system needs at least 0.2 MPa to overcome the return spring. Match your mounting using LB foot, FA flange, SDB pivot or TC trunnion brackets, and use the -S magnet option for CMSG/DMSG/EMSG sensor feedback.
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 MTF20X10SU FAQ
It provides a net pull of 93.4 N at 0.5 MPa and 146.1 N at 0.7 MPa. Because it is single-acting with a spring return, it requires a minimum operating pressure of 0.2 MPa to overcome the spring and retract the rod.
The spring constantly pushes the rod to the fully extended position, so on air loss the cylinder fails safely to the extended state. It cannot hold an arbitrary mid-stroke load; for that you would need a double-acting MF cylinder with an external rod lock. This U-cover variant also features a -S magnet for position sensing.
