Airtac MTF Mini Cylinder MTF32X80SCA
The AirTAC Airtac MTF Mini Cylinder MTF32X80SCA 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 MTF32X80SCA
Generating 266.8 N of pull at 0.5 MPa, this 32 mm bore AirTAC mini cylinder is built for single-acting tension and fail-safe-open tasks. The internal spring constantly pushes the 12 mm rod out to its extended rest, while feeding 1/4" ported air retracts it. Because the quoted force is already net of the spring, you get the full listed capacity for pulling loads, provided you maintain at least 0.2 MPa of operating pressure.
This JIS-standard round-body unit features a SUS304 stainless barrel and riveted aluminium covers, giving it a shorter overall envelope than an ISO 6432 cylinder of the same footprint while resisting mild washdown. The SCA suffix denotes the built-in magnet for CMSG/DMSG/EMSG sensors and a CA rear pivot cover. End-of-stroke deceleration is handled by fixed TPU bumper pads. For sizing, a practical safe working load is roughly 160 N (about 60% of the 0.5 MPa figure), which equates to lifting or holding around 13.6 kg with a 2:1 margin.

Where the Airtac MTF Mini Cylinder MTF32X80SCA Is Used
Tensioning Mechanisms
Pulls webbing or wire taut with 266.8 N at 0.5 MPa, safely handling around 13.6 kg with a 2:1 margin before releasing tension on air loss.
Fail-Safe-Open Valves
Holds a linkage retracted via air pressure, but the internal spring forces the rod out to automatically open the valve if the air supply drops.
Rejector Arms
Retracts a sorting diverter using 1/4" ported air, relying on the spring to snap the arm back to its extended rest position between cycles.
Is the Airtac MTF Mini Cylinder MTF32X80SCA the Right Cylinder?
When sizing this 32 mm bore, evaluate both ends of the range: the MTF25 yields 153.6 N at 0.5 MPa if your load is lighter, while the MTF40 provides 434.8 N at 0.5 MPa for heavier pulls. This MTF32X80SCA fits spring-open/air-close mechanisms perfectly, as the spring automatically drives the rod to the extended position upon air loss, though it cannot hold a mid-stroke load without an external lock.
Ensure your air supply meets the 0.2 MPa minimum floor required to overcome the spring force. The included -S magnet enables position sensing with CMSG, DMSG, or EMSG switches, and the CA back cover allows direct pivot mounting. Speeds of 50-800 mm/s are governed by flow controls, as end cushioning relies solely on fixed TPU bumpers.
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 MTF32X80SCA FAQ
This 32 mm bore cylinder delivers a net pull force of 266.8 N at 0.5 MPa and 405 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring and begin retracting the rod.
The spring constantly extends the 12 mm rod, meaning the cylinder fails to the extended position on air loss and cannot hold mid-stroke loads. The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG sensors, and the CA back cover provides a rear pivot mount.
