This model is discontinued
AirTAC has phased out the MTAL series. You can still order this code here: we ship the direct replacement MTBL40X80SU, with the same bore, stroke, output force, port and mounting, so it fits the same application. The replacement upgrades to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors (the MAL used CS1-M / DS1-M).
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X80SU
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X80SU is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø40mm bore and 80mm stroke, G1/4 ports and a fixed rubber bumper. Air drives the pull (work) stroke and the spring returns the rod — it rests extended on air loss. This model is discontinued; the direct replacement is the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X80SU.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X80SU
The AirTAC MTAL40X80SU is a discontinued 40mm bore, 80mm stroke single-acting pull cylinder. Air retracts the rod for the work stroke; an internal spring extends it when air is released, providing a fail-safe EXTENDED home position. It delivers a usable pull force of 439.4 N at 0.5 MPa and 650.4 N at 0.7 MPa.
The direct replacement is the MTBL40X80SU, matching the G1/4 port, M12x1.25 rod thread, and U flat-end back cover. This MTAL features a -S magnet for CS1-M/DS1-M sensors and threaded covers, whereas the MTBL upgrade uses CMSG/DMSG/EMSG switches and a riveted rolling-packed body. A fixed rubber bumper absorbs end-of-stroke impact.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X80SU Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X80SU |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X80SU |
| Bore size | Ø40 mm |
| 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. The AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X80SU carries the same single-acting ratings.
Usable Pull Force (Ø40mm)
| Pressure | Pull force (net of spring) |
|---|---|
| 0.5 MPa | 439.4 N |
| 0.7 MPa | 650.4 N |
Usable single-acting force after the return spring — lower than a same-bore double-acting cylinder. Size with a margin.

Where the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X80SU Is Used
Injection Mold Ejection
Pulls an injection mold ejector pin back 80mm against 439.4 N at 0.5 MPa, relying on the spring-extend fail-safe to clear the mold cavity on air loss.
PCB Test Fixture Clamps
Retracts a test fixture clamp via the M12x1.25 rod end, using the 650.4 N pull at 0.7 MPa to secure circuit boards before releasing them outward.
Packaging Flap Draw-back
Draws back a carton sealing flap using the G1/4 port's high flow capacity, ensuring the flap parks extended to allow box passage when air is cut.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X80SU with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X80SU
Replace the MTAL40X80SU directly with the MTBL40X80SU, confirming the 40mm bore, 80mm stroke, G1/4 port, PT thread, U back cover, and -S magnet (sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG). Operating pressure must be at least 0.2 MPa. The fail-safe home is EXTENDED; apply NO external load on the spring extend stroke, and use an external device for mid-stroke load holding.
To size up or down: the next smaller 32mm bore yields 261.2 N pull at 0.5 MPa, while the 40mm bore provides 439.4 N at 0.5 MPa. If higher force is needed, step up to a larger double-acting MAL cylinder, as 40mm is the largest MTAL bore.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X80SU (same bore/stroke/force)
- ✓ Same pull direction and extended fail-safe home
- ✓ Min 0.2 MPa; no external load on the spring return
- ✓ Sensor: swap CS1-M/DS1-M → CMSG/DMSG/EMSG
- ✓ Confirm back cover (CA / U) and thread (PT/NPT/G)
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 Front/rear covers are threaded — not for field disassembly.
- check For new builds, specify the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X80SU instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X80SU FAQ
Yes, the MTAL40X80SU is discontinued. The direct replacement is the MTBL40X80SU, matching the 40mm bore, 80mm stroke, G1/4 port, U back cover, and -S magnet. The MTBL upgrades the body to a riveted rolling-packed design and uses CMSG/DMSG/EMSG sensors instead of the older CS1-M/DS1-M.
This single-acting pull cylinder provides a usable pull force of 439.4 N at 0.5 MPa and 650.4 N at 0.7 MPa. It requires a minimum of 0.2 MPa to retract the rod against the spring. On air loss, the spring extends the rod to its fail-safe EXTENDED home position; it is not a lock, so an external device is needed to hold a mid-stroke load.
