This model is discontinued
AirTAC has phased out the MTAL series. You can still order this code here: we ship the direct replacement MTBL20X50SU, 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 MTAL20X50SU
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X50SU is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø20mm bore and 50mm stroke, G1/8 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50SU.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X50SU
The AirTAC MTAL20X50SU is a discontinued single-acting pull mini cylinder with a 20mm bore and 50mm stroke. Air retracts the rod while an internal spring extends it, yielding a fail-safe extended home position. It delivers 81.7 N of usable pull force at 0.5 MPa and uses a G1/8 port with an M8x1.25 rod end.
The direct replacement is the MTBL20X50SU, matching the bore, stroke, U back cover, and magnet. The MTAL uses threaded covers and a CS1-M / DS1-M magnet sensor, whereas the MTBL upgrades to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors. Apply no external load on the spring extend stroke to avoid damaging the internal return mechanism.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X50SU Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X50SU |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50SU |
| Bore size | Ø20 mm |
| Stroke | 50 mm |
| Acting type | Single acting, pull (spring extend) |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50SU carries the same single-acting ratings.
Usable Pull Force (Ø20mm)
| Pressure | Pull force (net of spring) |
|---|---|
| 0.5 MPa | 81.7 N |
| 0.7 MPa | 134.4 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 MTAL20X50SU Is Used
Electronic Tester Probe
Retracts a test probe on a PCB fixture with 81.7 N pull at 0.5 MPa, using the spring-extend fail-safe to lift the probe safely during an air loss.
Pick-and-Place Gripper
Closes a small pneumatic gripper jaw during assembly, relying on the 134.4 N pull at 0.7 MPa to draw back the mechanism quickly.
Label Dispenser Gate
Pulls a diverter gate shut on a packaging line, letting the internal spring extend the rod to open the gate and stop label feeding when air drops.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X50SU with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50SU
Replace this MTAL20X50SU with the MTBL20X50SU. Confirm the 20mm bore, 50mm stroke, G1/8 port, PT thread, 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 is 0.2-1.0 MPa minimum, and the fail-safe home is extended.
If sizing a new unit, step down to a 20mm bore for 81.7 N pull at 0.5 MPa, or step up to a 25mm bore for 137.2 N pull at 0.5 MPa. The 50mm stroke is standard and safe from rod-bending side-loads. The fixed rubber bumper absorbs end-of-stroke impact without adjustment.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50SU (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50SU instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X50SU FAQ
Yes, the MTAL20X50SU is discontinued. The direct replacement is the MTBL20X50SU, which matches the 20mm bore, 50mm stroke, U back cover, and -S magnet. You will only need to update your sensor choice from the older CS1-M / DS1-M to the new CMSG / DMSG / EMSG switches.
It is a single-acting pull cylinder, so air retracts the rod and the spring extends it. The fail-safe home is extended. The usable pull force is 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa, requiring a minimum working pressure of 0.2 MPa.
