This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X50U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X50U 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 MTAL40X50U
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X50U is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø40mm bore and 50mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X50U.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X50U
The AirTAC MTAL40X50U is a discontinued single-acting pull-type mini cylinder with a 40mm bore and 50mm stroke. Air retracts the rod while an internal spring extends it, providing a fail-safe extended home position. It delivers 439.4N of usable pull force at 0.5MPa and uses a G1/4 port with an M12x1.25 rod-end thread. The exact drop-in replacement is the MTBL40X50U, matching bore, stroke, force, and port.
This U-back-cover SKU lacks a magnet and cannot accept a position sensor. The MTAL uses threaded covers and older CS1-M/DS1-M switches, while the MTBL upgrade features a riveted rolling-packed body and CMSG/DMSG/EMSG sensors. A fixed rubber bumper absorbs end-of-stroke impact, and a 20um hard-chrome carbon-steel rod resists corrosion.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X50U Technical Specifications

| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X50U |
| Bore size | Ø40 mm |
| Stroke | 50 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X50U 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 MTAL40X50U Is Used
Injection Mold Ejector
Pulls an injection mold ejector pin back against 439.4N at 0.5MPa, ensuring the spring-extended fail-safe clears the parting line on air loss.
Press Brake Tensioner
Draws back a press brake tensioning strap using 650.4N at 0.7MPa, relying on the fixed rubber bumper to absorb the abrupt retracted stop.
CNC Chuck Release
Retracts a CNC lathe chuck latch with the 16mm rod, using the spring-extend function to safely open the mechanism during an air pressure failure.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X50U with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X50U
Replace this MTAL40X50U with the MTBL40X50U, confirming the 40mm bore, 50mm stroke, G1/4 port, PT thread, and U flat-end back cover. Because this SKU has no -S magnet, it cannot take a sensor; the MTBL upgrade uses CMSG/DMSG/EMSG switches. Maintain a minimum 0.2MPa operating pressure and apply no external load on the spring-extend stroke. If sizing down, the 32mm bore neighbor provides 261.2N pull at 0.5MPa; if stepping up, the 40mm bore is the largest available in this mini series. The spring provides a fail-safe extended rest, not a locked hold.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X50U (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X50U instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X50U FAQ
Yes, the MTAL40X50U is discontinued. The exact drop-in replacement is the MTBL40X50U, which matches the 40mm bore, 50mm stroke, G1/4 port, and U back cover. 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 439.4N of usable pull force at 0.5MPa and 650.4N at 0.7MPa. It operates on 0.2-1.0MPa pressure with speeds of 50-800mm/s. Because the spring opposes the air stroke, the net pull force is lower than a double-acting cylinder. The fail-safe home is extended, and the fixed rubber bumper prevents end-of-stroke damage.
