Airtac MTF Mini Cylinder MTF32X80CM
The AirTAC Airtac MTF Mini Cylinder MTF32X80CM is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø32mm bore and 80mm stroke, 1/4" 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 MTF32X80CM
Delivering 266.8 N of net pull at 0.5 MPa, this 32 mm bore mini cylinder is built for spring-open, air-close tasks. The internal spring constantly pushes the 12 mm rod out, while feeding air to the 1/4 inch port retracts it. Because the MTF32X80CM lacks the -S suffix, it has no magnet and cannot host CMSG, DMSG, or EMSG position sensors.
The riveted rolling-packed construction pairs a SUS304 stainless barrel with aluminium covers, yielding a JIS-standard round body that is physically shorter than a comparable ISO 6432 unit. It uses fixed TPU bumper pads for end-of-stroke damping rather than an adjustable cushion. For a practical 2:1 safety margin, expect a safe vertical lift capacity of roughly 13.6 kg.

Theoretical Output Force (Ø32mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 266.8 N |

Where the Airtac MTF Mini Cylinder MTF32X80CM Is Used
Tension Control
Pulls webbing or filaments taut with 266.8 N of force at 0.5 MPa, releasing tension instantly when air is removed.
Fail-Safe Gate Opening
Holds a guard door open pneumatically; the spring automatically pushes the rod out to unlatch the door upon air loss.
Part Rejector
Retracts a 12 mm pin to let parts pass, then springs back out to divert defective items off the line.
Is the Airtac MTF Mini Cylinder MTF32X80CM the Right Cylinder?
When sizing this 80 mm stroke unit, compare both directions: the MTF25 bore provides 153.6 N at 0.5 MPa, while the larger MTF40 offers 434.8 N. This MTF32 hits a solid middle ground. Ensure your supply exceeds the 0.2 MPa floor required to overcome the return spring.
The CM round-end back cover suits direct rear mounting, and you can adapt the body using LB foot, FA flange, or TC trunnion brackets. Remember that on air loss, the spring drives the rod to the fully extended position—it will not hold a mid-stroke load.
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 MTF32X80CM FAQ
It provides a net pull force of 266.8 N at 0.5 MPa and 405 N at 0.7 MPa. You must supply at least 0.2 MPa to overcome the internal spring and retract the rod.
No, this specific SKU lacks the -S magnet, so CMSG, DMSG, or EMSG switches will not function. You would need the -S variant for sensing. The SUS304 stainless body is also highly resistant to mild washdown environments.
