Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL40X80SCA
The AirTAC Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL40X80SCA is a genuine single acting, pull (spring extend) aluminum-barrel mini round cylinder with a Ø40mm bore and 80mm stroke, G1/4 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 MTBL40X80SCA
The AirTAC MTBL40X80SCA is a 40mm bore, 80mm stroke single-acting pull cylinder. Air retracts the rod while an internal spring extends it, yielding a fail-safe extended home position. It generates a usable pull force of 339.1 N at 0.5 MPa and 550.1 N at 0.7 MPa.
This configuration includes a built-in magnet for CMSG, DMSG, or EMSG sensor switches and a CA pivot back cover for arcing loads. The riveted aluminum barrel and 20 um hard-chrome carbon-steel rod provide durability. It uses a fixed rubber bumper, lacking adjustable air cushions.

| Stroke | 80 mm |
| Acting type | Single acting, pull (spring extend) |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.2 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| 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 (Ø40mm)
| Pressure | Pull force (net of spring) |
|---|---|
| 0.5 MPa | 339.1 N |
| 0.7 MPa | 550.1 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 MTBL40X80SCA Is Used
Textile Loom Tensioning
Pulls thread guides closed with 339.1 N at 0.5 MPa, safely spring-extending to release tension on air loss.
PCB Router Gate
Draws a routing lane gate closed; the CA pivot absorbs arcing motion as the mechanism cycles.
Packaging Flap Seating
Pulls carton flaps down against a seam; the 80mm stroke and fail-safe extended home prevent jams.
Is the Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL40X80SCA the Right Cylinder?
The 40mm bore offers the highest pull force in the MTBL range, delivering 339.1 N at 0.5 MPa. If your application requires less force, the 32mm bore provides 224.8 N at 0.5 MPa. A minimum operating pressure of 0.2 MPa is required to overcome the return spring. The CA pivot back cover swings on a pin, making it ideal for angular loads, unlike the rigid U flat-end cover. The -S magnet enables position detection via CMSG reed or DMSG/EMSG electronic switches. Avoid applying external loads during the spring-extend return stroke. The PT thread port is G1/4.
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 MTBL40X80SCA FAQ
The usable pull force is 339.1 N at 0.5 MPa and 550.1 N at 0.7 MPa. A minimum operating pressure of 0.2 MPa is required to overcome the internal return spring.
The CA back cover is a pivot clevis that swings on a pin to handle arcing angular loads. The -S magnet allows CMSG reed and DMSG/EMSG electronic sensors to detect rod position.
