Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL40X40CA
The AirTAC Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL40X40CA is a genuine single acting, pull (spring extend) aluminum-barrel mini round cylinder with a Ø40mm bore and 40mm 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 MTBL40X40CA
The AirTAC MTBL40X40CA is a compact single-acting pull-type aluminum mini cylinder engineered for applications where the useful work occurs on the retraction stroke. Pressurized air entering the G1/4 port draws the Ø16 mm carbon-steel rod inward, while an internal spring drives it back out to a fail-safe extended home when air is released. At 0.5 MPa, this 40 mm bore generates a usable pull force of 339.1 N (net of the opposing spring), making it well-suited for heavy-duty tensioning within a 40 mm stroke.
This SKU features a CA pivot (clevis) back cover designed to swing on a pin, easily accommodating arcing or angular loads that would bind a rigidly fixed cylinder. Because this configuration lacks the -S magnet code, it cannot accept an AirTAC CMSG, DMSG, or EMSG position sensor. The riveted rolling-packed aluminum barrel keeps the body light, and end-of-stroke deceleration is handled by a fixed rubber bumper rather than an adjustable air cushion. Note that the overall length is calculated as A + 2 x stroke, meaning the spring-extend body is inherently longer than a double-acting equivalent.

| 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 MTBL40X40CA Is Used
Stamping Press Blank Holder
Pulls a blank holder down with 339.1 N at 0.5 MPa to secure sheet metal during a stamping cycle, with the spring-extend design ensuring the clamp lifts clear if air pressure drops.
Packaging Lid Closer
Draws a carton lid closed on a packaging line; the CA clevis bracket accommodates the side-to-side arcing motion as the lid pivots into place.
Welding Fixture Clamp
Retracts to pull a heavy steel component into a welding fixture. The fail-safe extended home pushes the part back out, allowing safe robotic unloading after the weld cools.
Is the Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL40X40CA the Right Cylinder?
Select this 40 mm bore when you need substantial pulling power, yielding 339.1 N at 0.5 MPa and 550.1 N at 0.7 MPa. If your mechanism requires less force, stepping down to the 32 mm bore provides 224.8 N at 0.5 MPa; if you need maximum pull in this mini format, this 40 mm is the largest available single-acting option. Choose the MTBL pull-type over the MSBL push-type when your machine requires a fail-safe extended rest position upon air loss. Ensure your system supplies at least 0.2 MPa to overcome the return spring, and never apply an external load during the unpowered extend stroke to prevent damaging the internal mechanism. For replacements, verify the PT tapered port thread, M12x1.25 rod-end thread, CA pivot cover, and confirm that no magnet is required.
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 MTBL40X40CA FAQ
The usable pull force (net of the return spring) is 22.6 N at 0.2 MPa, 128.1 N at 0.3 MPa, 233.6 N at 0.4 MPa, 339.1 N at 0.5 MPa, 444.6 N at 0.6 MPa, and 550.1 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the internal spring and retract the rod.
No, this specific SKU lacks the built-in magnet (-S code), so it cannot accept AirTAC CMSG, DMSG, or EMSG reed or electronic sensors. Regarding fail-safe operation, air retracts the rod to do the pulling work, but if air pressure is lost or the valve is closed, the internal spring forces the rod back out to its extended home position.
