This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X50SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X50SU 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 MTAL40X50SU
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X50SU 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X50SU.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X50SU
The AirTAC MTAL40X50SU 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, yielding a fail-safe extended home position. It delivers a usable pull force of 439.4 N at 0.5 MPa. The exact drop-in replacement is the MTBL40X50SU, matching the bore, stroke, G1/4 port, and U back cover.
This SKU includes the -S magnet for position sensing via older CS1-M or DS1-M switches, whereas the MTBL replacement uses CMSG/DMSG/EMSG sensors. The MTAL features threaded covers and a fixed rubber bumper, while the MTBL upgrades to a riveted rolling-packed body. Apply no external load on the spring extend stroke to prevent damage.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X50SU Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X50SU |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X50SU |
| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X50SU 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 MTAL40X50SU Is Used
Injection Mold Ejector Reset
Pulls an injection molding ejector plate back on air, using the 439.4 N force at 0.5 MPa, while the spring-extended fail-safe safely parks the plate out during air loss.
Packaging Flap Retractor
Retracts a carton sealing flap on a packaging line using 650.4 N at 0.7 MPa, ensuring the flap clears the glue applicator before the spring extends it home.
Press Brake Tool Drawback
Draws back a small press brake alignment pin with a 50mm stroke, relying on the G1/4 port flow and 16mm rod to handle the repetitive lateral tool clearance task.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X50SU with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X50SU
To replace this MTAL40X50SU, use the drop-in MTBL40X50SU. Confirm the 40mm bore, 50mm stroke, M12x1.25 rod thread, PT G1/4 port, U flat-end back cover, and the -S magnet. Remember the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. Operating pressure must be at least 0.2 MPa, and the fail-safe home is extended. Never apply external load to the spring extend stroke.
If sizing down, the 32mm bore neighbour provides 261.2 N pull at 0.5 MPa. If stepping up, 40mm is the largest MTAL bore, offering 439.4 N at 0.5 MPa and 650.4 N at 0.7 MPa. The fixed rubber bumper absorbs end-of-stroke impact; it is not an adjustable cushion or a mid-stroke lock.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X50SU (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X50SU instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X50SU FAQ
Yes, the MTAL40X50SU is discontinued. The exact drop-in replacement is the MTBL40X50SU, which matches the 40mm bore, 50mm stroke, G1/4 port, U back cover, and -S magnet. You must upgrade your sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
It is a single-acting pull cylinder with a 40mm bore, 16mm rod, and 50mm stroke. Usable pull force is 439.4 N at 0.5 MPa and 650.4 N at 0.7 MPa. Operating pressure is 0.2-1.0 MPa, speed is 50-800 mm/s, and it uses a fixed rubber bumper with a fail-safe extended home position.
