Airtac MTF Mini Cylinder MTF20X150CM
The AirTAC Airtac MTF Mini Cylinder MTF20X150CM is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø20mm bore and 150mm 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 MTF20X150CM
Delivering 93.4 N of net pull at 0.5 MPa, this single-acting spring-return cylinder is engineered for tensioning and air-close applications. The internal spring constantly holds the piston rod in the extended position, while supplying air to the 1/8 inch port retracts it. If air pressure drops, the mechanism safely fails to the extended state.
Built with a SUS304 stainless steel barrel and aluminium covers, the JIS-standard round-body construction is more compact than an ISO 6432 unit of the same footprint. This specific configuration uses a CM round-end rear cover and stretches to the maximum standard stroke of 150 mm. Keep in mind this base SKU lacks a magnet, meaning it cannot host CMSG, DMSG, or EMSG sensors without upgrading to the -S variant.

Theoretical Output Force (Ø20mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 93.4 N |

Where the Airtac MTF Mini Cylinder MTF20X150CM Is Used
Tension Control
Pulls web materials or cables tight with a 93.4 N force at 0.5 MPa, releasing tension instantly when air is vented.
Fail-Safe Opening
Holds lids or gates open by spring force, using the 150 mm stroke to pull them closed only when compressed air is applied.
Part Retraction
Draws lightweight 4.8 kg fixtures or workpieces out of a conveyor lane on command, defaulting to the extended position during downtime.
Is the Airtac MTF Mini Cylinder MTF20X150CM the Right Cylinder?
When sizing this 20 mm bore option, evaluate your tension requirements against its 146.1 N pull at 0.7 MPa. If your task needs less force, there is no smaller MTF bore available, but stepping up to the MTF25 provides a robust 153.6 N at 0.5 MPa. A minimum of 0.2 MPa operating pressure is mandatory to overcome the internal spring. For mounting, match your fixture to LB foot, FA flange, or TC trunnion options. Factoring a 2:1 safety margin, the 93.4 N pull at 0.5 MPa yields an effective vertical lift capacity of about 4.8 kg.
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 MTF20X150CM FAQ
This cylinder generates 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 retract the rod against the spring, with a maximum pressure limit of 1.0 MPa and a proof pressure of 1.5 MPa.
Because it is a single-acting pull cylinder, the internal spring drives the rod to the fully extended position when air is removed or lost. It cannot hold a mid-stroke load. Additionally, this non-magnetic CM cover version cannot accept position sensors.
