This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X30U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X30U in place of this model. 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 MTAL40X30U
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X30U is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø40mm bore and 30mm 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 drop-in replacement is the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X30U.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X30U
The AirTAC MTAL40X30U is a discontinued single-acting pull-type mini cylinder. Air retracts the rod to do the work, while an internal spring extends it back out. It provides a usable pull force of 439.4 N at 0.5 MPa and parks in a fail-safe extended position on air loss. The exact drop-in replacement is the MTBL40X30U.
This 40mm bore unit uses a G1/4 port and a 16mm carbon-steel rod with a 20um hard chrome plating. It features a fixed rubber bumper and a flat-end U back cover. Because this specific SKU lacks the -S magnet option, it cannot take a position sensor. The MTBL upgrade replaces the older threaded covers with a riveted rolling-packed body.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X30U Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X30U |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X30U |
| Bore size | Ø40 mm |
| Stroke | 30 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X30U 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 MTAL40X30U Is Used
Injection Mold Ejector
Retracts an ejection pin during the 439.4 N pull stroke at 0.5 MPa, relying on the spring to safely push the pin back out when air drops.
Press Brake Tensioner
Draws back a brake belt mechanism in heavy steel fabrication, using the fixed rubber bumper to absorb the 30mm stroke shock.
Packaging Lid Lifter
Pulls a carton lid closed during case packing, where the fail-safe extended home guarantees the lid opens if the pneumatic supply fails.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X30U with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X30U
To replace the MTAL40X30U, specify the MTBL40X30U and confirm the 40mm bore, 30mm stroke, G1/4 port, PT thread, U flat-end back cover, and 0.2 MPa minimum working pressure. The MTBL upgrade changes the sensor family from CS1-M/DS1-M to CMSG/DMSG/EMSG, but since this no-magnet SKU cannot take a sensor anyway, you simply lose the threaded covers for a riveted body. Remember the fail-safe home is extended, and apply no external load on the spring extend stroke for safety.
To size this cylinder, step down to the 32mm bore if you need less force (it yields 261.2 N at 0.5 MPa), or step up to the 40mm bore's maximum standard 100mm stroke if your draw-back distance needs to be longer. At 30mm stroke, this model handles compact pulls with excellent lateral stability.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X30U (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X30U instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X30U FAQ
Yes, the MTAL40X30U is discontinued. The exact drop-in replacement is the MTBL40X30U, which matches the 40mm bore, 30mm stroke, 439.4 N pull force at 0.5 MPa, G1/4 port, and U flat-end mounting. You simply upgrade from threaded covers to a riveted rolling-packed body.
The usable pull force is 439.4 N at 0.5 MPa and 650.4 N at 0.7 MPa. It is single-acting, so air retracts the rod and an internal spring extends it. The fail-safe home is extended, meaning on air loss the spring pushes the rod out. It requires a minimum 0.2 MPa to operate.
