This model is discontinued
AirTAC has phased out the MTAL series. You can still order this code here: we ship the direct replacement MTBL20X20SU, 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 MTAL20X20SU
The AirTAC MTAL Rear Single Acting Mini Cylinder MTAL20X20SU is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø20mm bore and 20mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20SU.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X20SU
The AirTAC MTAL20X20SU is a discontinued single-acting pull-type mini cylinder. Air retracts the rod while an internal spring extends it. The direct replacement is the MTBL20X20SU. This 20mm bore provides a usable pull force of 81.7 N at 0.5 MPa.
It features a G1/8 port and an 8mm rod. The U flat-end back cover offers a rigid rear mount. The -S magnet works with CS1-M or DS1-M switches. The MTBL upgrade uses a riveted rolling-packed body and CMSG sensors.

| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20SU |
| Bore size | Ø20 mm |
| Stroke | 20 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20SU 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 MTAL20X20SU Is Used
Textile Loom Tension
Pulls a thread tension guide back during air retraction. The 81.7 N pull at 0.5 MPa handles the load. The spring extends safely on air loss.
Packaging Flap Deflector
Draws a cardboard flap guide out of the tape path. The 8mm rod and 20mm stroke fit tight carton sealing machinery.
Small Part Ejector
Retracts a tiny electronic component ejector pin. The U flat-end cover mounts rigidly to the machine frame.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X20SU with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20SU
Replace this MTAL20X20SU with the MTBL20X20SU. Confirm the 20mm bore, 20mm stroke, G1/8 port, PT thread, U back cover, and -S magnet. The MTBL upgrade changes the sensor family from CS1-M to CMSG. Minimum working pressure is 0.2 MPa. The fail-safe home is extended. Apply no external load on the spring extend stroke. If you need less force, step down is not available as 20mm is the smallest. To step up, the 25mm bore yields 137.2 N at 0.5 MPa.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20SU (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20SU instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X20SU FAQ
Yes, the MTAL20X20SU is discontinued. The direct replacement is the MTBL20X20SU. It matches the 20mm bore, 20mm stroke, G1/8 port, and U back cover. The MTBL uses a riveted body and CMSG sensors instead of threaded covers and CS1-M switches.
The usable pull force is 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa. Minimum working pressure is 0.2 MPa. The fixed rubber bumper stops the stroke. It cannot hold a load mid-stroke without an external lock.
