Airtac MTF Mini Cylinder MTF20X50SCM
The AirTAC Airtac MTF Mini Cylinder MTF20X50SCM is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø20mm bore and 50mm 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 MTF20X50SCM
Generating 93.4 N of pull at 0.5 MPa, this 20 mm bore single-acting cylinder relies on an internal spring to push the rod out, while compressed air retracts it. Because the spring holds the piston normally extended, the MTF20X50SCM fails safely to the open position if air pressure drops. The quoted force is already net of the spring resistance, requiring at least 0.2 MPa to overcome it. The 1/8 inch port and M8x1.25 male rod thread keep the pneumatic footprint compact.
Built as a JIS-standard round-body mini cylinder with a SUS304 stainless barrel and riveted aluminium covers, it delivers a shorter mounting length than an equivalent ISO 6432 unit. It uses fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable cushion. The included -S magnet enables CMSG, DMSG or EMSG switches for position sensing, and the CM round-end back cover suits tight spatial envelopes. For a practical guideline, the safe working load is roughly 56 N, or it can vertically lift about 4.8 kg with a 2:1 margin.

Where the Airtac MTF Mini Cylinder MTF20X50SCM Is Used
Tension Control
Pulls light filaments or webs with a safe working load near 56 N, releasing tension instantly when air is removed.
Fail-Safe Opening
Holds a valve or gate closed via air retraction, with the internal spring driving the 8 mm rod out to open it during air loss.
Vertical Retraction
Lifts or suspends a 4.8 kg load vertically against gravity during the air-pull stroke, lowering it safely when vented.
Is the Airtac MTF Mini Cylinder MTF20X50SCM the Right Cylinder?
If the 93.4 N pull at 0.5 MPa is insufficient for your tensioning task, step up to the MTF25 which provides 153.6 N; as the smallest bore in the series, there is no smaller MTF option. This single-acting pull configuration is optimal for spring-open, air-close operations where losing air pressure must force the mechanism out to the extended state. Ensure your supply meets the 0.2 MPa minimum floor to retract the rod against the spring. Mounting options include LB foot, FA flange, SDB pivot and TC trunnion brackets, while position detection requires the -S magnet variant paired with CMSG, DMSG or EMSG sensors.
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 MTF20X50SCM FAQ
It delivers a net pull force of 93.4 N at 0.5 MPa and 146.1 N at 0.7 MPa. You must supply at least 0.2 MPa to overcome the internal return spring and retract the rod.
The spring constantly extends the rod, meaning air only pulls it in. On air loss, the spring pushes the rod back out to the extended position. The SUS304 stainless build resists mild corrosion, and the -S magnet allows CMSG, DMSG or EMSG sensors to track position.
