Airtac MTF Mini Cylinder MTF20X60CM
The AirTAC Airtac MTF Mini Cylinder MTF20X60CM is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø20mm bore and 60mm 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 MTF20X60CM
Generating 93.4 N of pull at 0.5 MPa, the AirTAC MTF20X60CM is a JIS-standard round-body mini cylinder built for single-acting pull tasks. An internal spring constantly pushes the 8 mm rod out to its extended rest, while supplying air to the 1/8" port retracts it. Because the spring dominates on air loss, the rod fails safely to the extended position. The quoted force is already net of the spring, meaning you get the full pulling power without subtracting return resistance.
This 20 mm bore unit uses a SUS304 stainless barrel and riveted aluminium covers to resist mild washdown, offering a shorter mounting envelope than an ISO 6432 cylinder of the same size. It stops on fixed TPU bumper pads. For practical sizing, expect a safe working load of roughly 56 N, or a vertical lift capacity of about 4.8 kg with a 2:1 margin. This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac MTF Mini Cylinder MTF20X60CM Is Used
Tension Control
Pulls webbing or filaments tight with a 93.4 N net force at 0.5 MPa, releasing tension only when air is applied.
Fail-Safe Open Gate
Holds a small access door open by spring force and pulls it closed via air, ensuring the door opens automatically if pneumatic pressure drops.
Clamp Release
Keeps a packaging clamp extended by spring pressure, retracting the 8 mm rod to clear the part when compressed air is supplied.
Is the Airtac MTF Mini Cylinder MTF20X60CM the Right Cylinder?
When sizing this 20 mm bore unit, compare it directly against the MTF25, which raises the pull force to 153.6 N at 0.5 MPa. Since 20 mm is the smallest available MTF bore, stepping down is not an option. Choose this model for spring-open, air-close jobs like tensioning or clamping where the rod must return to the extended position safely upon air loss. Ensure your air supply meets the 0.2 MPa minimum floor required to overcome the internal spring. Mounting is flexible via LB foot, FA flange, SDB pivot, or TC trunnion brackets, and the CM round-end back cover fits neatly into tight spaces. Note that because this SKU lacks the -S magnet, it cannot support position 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 MTF20X60CM FAQ
It delivers a net pull force of 93.4 N at 0.5 MPa and 146.1 N at 0.7 MPa. The operating pressure ranges from 0.2 MPa to 1.0 MPa, but you need at least 0.2 MPa to overcome the return spring. The proof pressure is 1.5 MPa.
No, this specific SKU does not include a magnet. You must select an MTF model with the -S suffix to use CMSG, DMSG, or EMSG magnetic switches. Additionally, the internal spring drives the rod to the extended position on air loss, so it will not hold a mid-stroke load.
