Airtac MTF Mini Cylinder MTF20X100CA
The AirTAC Airtac MTF Mini Cylinder MTF20X100CA is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø20mm bore and 100mm 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 MTF20X100CA
Generating 93.4 N of net pull force at 0.5 MPa, this JIS-standard round-body mini cylinder uses a SUS304 stainless barrel and riveted aluminium covers to save mounting length compared to ISO 6432 units. The MTF20X100CA is a single-acting pull design: an internal spring holds the 8 mm rod extended at rest, while supplying air to the 1/8" port retracts it. Because the spring constantly pushes outward, the cylinder fails to the extended position if air pressure drops, making it ideal for spring-open mechanisms. The quoted pull force is already net of the spring resistance, requiring a minimum 0.2 MPa operating pressure to overcome it. Fixed TPU bumper pads absorb end-of-stroke impacts across the 100 mm travel, and the rear CA pivot cover simplifies direct body mounting.
For sizing purposes, the effective pull at 0.5 MPa translates to roughly 9.5 kgf, which yields a safe vertical lift capacity of about 4.8 kg when applying a 2:1 safety margin. This base SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors; choose the -S variant if switch tracking is required.

Where the Airtac MTF Mini Cylinder MTF20X100CA Is Used
Tension Return Mechanism
Pulls a light tensioning jig back against a stop using 93.4 N of force at 0.5 MPa, relying on the internal spring to hold the fixture extended during idle periods.
Spring-Open Gate Valve
Uses air to pull the valve closed, while the spring automatically drives the 8 mm rod back out to the extended position to open the gate safely upon air loss.
Rejector Arm Retract
Retracts a small conveyor reject arm out of the product path using pneumatic pull, allowing the spring to push the arm back into standby position for the next cycle.
Is the Airtac MTF Mini Cylinder MTF20X100CA the Right Cylinder?
If 93.4 N of pull at 0.5 MPa is insufficient for your load, step up to the MTF25, which provides 153.6 N under the same pressure. As the smallest bore in the series, there is no smaller MTF option, making this the baseline for light-tension tasks. Choose this single-acting pull configuration when you need air to close or retract a mechanism and a spring to automatically return it to the open state. Remember that at least 0.2 MPa of air pressure is required to overcome the return spring. The CA rear pivot cover works well with pivot mounts, and you must select an -S model if your application requires magnetic sensing.
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 MTF20X100CA FAQ
This single-acting pull cylinder generates 93.4 N of net pull force 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 return spring, with a maximum pressure limit of 1.0 MPa and a proof pressure of 1.5 MPa.
The internal spring constantly holds the rod in the extended position. Applying air to the 1/8" port retracts the rod, and releasing air lets the spring push it back out. If air pressure is lost, the cylinder fails to the extended state, and this SKU lacks a magnet for position sensing.
