Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL32X80SU
The AirTAC Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL32X80SU is a genuine single acting, pull (spring extend) aluminum-barrel mini round cylinder with a Ø32mm bore and 80mm stroke, G1/8 air ports and a fixed rubber bumper. Air drives the pull (work) stroke and the spring returns the rod — it rests extended on air loss.

About the Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL32X80SU
The AirTAC MTBL32X80SU is a compact single-acting pull-type mini cylinder featuring a 32mm bore and an 80mm stroke. Air retracts the Ø12mm hard-chrome carbon-steel rod, while an internal spring extends it to a fail-safe extended home position. It delivers a usable pull force of 224.8 N at 0.5 MPa, making it well-suited for drawing mechanisms closed across a long travel distance. The riveted rolling-packed aluminum barrel keeps the body light for tight spaces.
This U variant includes a flat-end back cover for rigid mounting and a built-in magnet (-S) for position detection. You can mount CMSG reed switches or DMSG/EMSG solid-state sensors directly to the body. The unit relies on a fixed rubber bumper for end-of-stroke damping and requires a minimum 0.2 MPa operating pressure to overcome the return spring. Overall length follows the A + 2 x stroke rule, making it physically longer than a double-acting equivalent.

| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 100 mm |
Single-acting minimum working pressure is 0.2 MPa (the air must overcome the return spring). Do not apply an external load during the spring return stroke. Thread options: PT / G / NPT.
Usable Pull Force (Ø32mm)
| Pressure | Pull force (net of spring) |
|---|---|
| 0.5 MPa | 224.8 N |
| 0.7 MPa | 363.0 N |
These are the usable single-acting forces after the return spring — lower than a same-bore double-acting MBL. Size with a margin.

Where the Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL32X80SU Is Used
Packaging Lid Lifting
Holds a carton sealer lid open by pulling it down with 224.8N at 0.5MPa; the spring extends the rod to safely prop the lid open during air loss.
Textile Tensioning
Draws a fabric tensioning roller closed across an 80mm stroke, using the fail-safe extended home to maintain baseline tension when the line stops.
Slide Gate Drawback
Retracts a small parts-sorting slide gate via a DMSG sensor signal, relying on the fixed rubber bumper to absorb the 80mm stroke impact.
Is the Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL32X80SU the Right Cylinder?
For sizing, the 32mm bore here yields 224.8 N of pull force at 0.5 MPa. If your pulling load is lighter, step down to the 25mm bore (132.6 N at 0.5 MPa); if you need more pull power, step up to the 40mm bore (339.1 N at 0.5 MPa). Choose this MTBL pull-type over the MSBL push-type when a power loss must leave the rod safely extended rather than retracted. Remember that the return spring opposes the air stroke, so usable force is lower than a double-acting MBL.
This 80mm stroke demands attention to side loads and rod bending—use a pivot bracket or guide the load to prevent premature seal wear. Never apply an external load during the spring-extend return stroke. Replacement matches require: 32mm bore, 80mm stroke, G1/8 port, PT thread, U flat-end back cover, and the -S magnet.
Quick checklist
- ✓ Usable pull force at your pressure (min 0.2 MPa)
- ✓ Fail-safe rest position (extended)
- ✓ No external load on the spring return stroke
- ✓ Magnet (S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.2 – 1.0 MPa (min 0.2 to overcome the spring).
- check Apply no external load on the spring return stroke.
- check Avoid side load on the piston rod.
- check Use the correct mounting accessory (LB / FA / SDB) and back cover (CA / U).
- check Installation by qualified personnel per AirTAC docs.
Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL32X80SU FAQ
The usable pull force (net of spring) is 17.6N @0.2MPa, 86.6N @0.3MPa, 155.7N @0.4MPa, 224.8N @0.5MPa, 293.9N @0.6MPa, and 363N @0.7MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring.
It is single-acting pull, so air retracts the rod while the spring extends it. On air loss, the spring drives the rod to a fail-safe extended home. The -S built-in magnet lets you track this position using CMSG reed or DMSG/EMSG electronic switches.
