Airtac MTF Mini Cylinder MTF20X15SCM
The AirTAC Airtac MTF Mini Cylinder MTF20X15SCM is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø20mm bore and 15mm 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 MTF20X15SCM
Delivering 93.4 N of net pull force at 0.5 MPa, this AirTAC MTF20X15SCM mini cylinder uses a single-acting pull mechanism where an internal spring pushes the rod out and air retracts it. The SUS304 stainless round body with riveted aluminium covers is notably shorter than an ISO 6432 cylinder of the same bore and stroke, saving valuable mounting space. Because the spring holds the rod extended, the cylinder fails safely to the out position if air pressure drops.
It features a 20 mm bore, an 8 mm rod with an M8x1.25 male thread, and a 1/8 inch port. The CM round-end back cover suits compact pivot arrangements. For position feedback, the built-in -S magnet works with CMSG, DMSG, or EMSG switches. Factoring a 2:1 safety margin, it handles a vertical lift of about 4.8 kg. Fixed TPU bumper pads absorb end-of-stroke impacts across the 50-800 mm/s speed range.

Where the Airtac MTF Mini Cylinder MTF20X15SCM Is Used
Tension Control
Pulls light tensioning guides with a 4.8 kg vertical lift capacity, relying on air to retract while the spring maintains baseline tension.
Fail-Safe Open Gate
Holds a small access flap closed via air pressure; the spring automatically pushes the rod out to open the gate during an air loss event.
Clamp Release
Retracts a 56 N holding pin to release lightweight packaging components, using the spring to drive the pin back into the locked position.
Is the Airtac MTF Mini Cylinder MTF20X15SCM the Right Cylinder?
Choose this 20 mm bore if your task requires a spring-open, air-close action with a safe working load around 56 N. If your application demands less force, note that 20 mm is the smallest available MTF bore. If you need more power, step up to the MTF25, which provides 153.6 N of pull at 0.5 MPa. Operating pressure must stay between 0.2 and 1.0 MPa, as a minimum of 0.2 MPa is required to overcome the return spring. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion 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 MTF20X15SCM FAQ
This single-acting cylinder delivers a net pull force of 93.4 N at 0.5 MPa and 146.1 N at 0.7 MPa. It requires an operating pressure of at least 0.2 MPa to overcome the internal return spring, with a maximum pressure limit of 1.0 MPa.
The spring constantly extends the rod, meaning air is only used to pull it in. If air pressure is lost, the spring drives the rod to the fully extended position. It cannot hold a load at an arbitrary mid-stroke point; you would need a double-acting MF cylinder with an external rod lock for that.
