Airtac MTF Mini Cylinder MTF20X10CA
The AirTAC Airtac MTF Mini Cylinder MTF20X10CA 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 MTF20X10CA
Delivering 93.4 N of net pull force at 0.5 MPa, the AirTAC MTF20X10CA is a JIS-standard round-body mini cylinder built for single-acting pull operation. An internal spring holds the 8 mm rod extended at rest, while supplying air to the 1/8 inch port retracts it. Because the spring drives the rod out upon air loss, the cylinder inherently fails to the extended position. The SUS304 stainless steel barrel and riveted aluminium covers yield a shorter mounting envelope than an ISO 6432 unit of identical bore and stroke, while resisting mild washdown corrosion.
This 20 mm bore model pulls with 146.1 N at 0.7 MPa and requires a minimum 0.2 MPa to overcome the spring. With a 2:1 safety margin, it provides an effective vertical lift capacity of about 4.8 kg, making it ideal for light tensioning tasks. The 10 mm stroke uses fixed TPU bumper pads for end-of-stroke deceleration. Note that this specific SKU lacks a magnet and cannot host position sensors; adding the -S option enables CMSG, DMSG, or EMSG switches.

Where the Airtac MTF Mini Cylinder MTF20X10CA Is Used
Light Tensioning
Pulls light cables or springs with a 4.8 kg effective lift capacity, releasing tension automatically when air pressure drops.
Fail-Safe Opening
Keeps a small access hatch or vent normally open via spring force, using the 93.4 N air pull to close it securely.
Clamp Retraction
Holds a small workpiece extended by default and retracts the 8 mm rod to clear the area when actuated by compressed air.
Is the Airtac MTF Mini Cylinder MTF20X10CA the Right Cylinder?
Choose this 20 mm bore when a compact spring-open, air-close action is required, providing a safe working load of roughly 56 N. If your application demands greater retraction force, step up to the MTF25X10CA, which delivers 153.6 N at 0.5 MPa. As the smallest available bore in the series, there is no smaller MTF option for scaling down. Operating pressure must stay between 0.2 and 1.0 MPa to function correctly.
The integrated CA back cover pivot simplifies rear mounting arrangements, complementing standard LB foot, FA flange, SDB pivot-block, and TC trunnion options. Remember that this non-magnetized version cannot accept sensing switches; for position feedback, select the -S magnet variant to support 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 MTF20X10CA FAQ
This single-acting 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 internal spring, with a maximum pressure of 1.0 MPa and a proof pressure of 1.5 MPa.
The spring constantly extends the rod, so air is only used to retract it, meaning the cylinder fails to the extended position on air loss. This SKU does not include a magnet and cannot accept position sensors; you must choose the -S variant to use CMSG, DMSG, or EMSG switches.
