This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20U 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 MTAL20X20U
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X20U 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 drop-in replacement is the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20U.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X20U
The AirTAC MTAL20X20U is a discontinued single-acting pull-type mini cylinder with a 20mm bore and 20mm stroke. Air retracts the rod while an internal spring extends it, yielding a usable pull force of 81.7 N at 0.5 MPa. The direct drop-in replacement is the MTBL20X20U, which matches the bore, stroke, G1/8 port, and U back cover.
This U-cover SKU lacks the -S magnet option and cannot accept a position sensor. The MTAL uses threaded covers and older CS1-M/DS1-M sensors, whereas the MTBL upgrade features a riveted rolling-packed body. A fixed rubber bumper absorbs end-of-stroke impact, and the spring provides a fail-safe extended home position on air loss.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X20U Technical Specifications

| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20U |
| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20U 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 MTAL20X20U Is Used
Electronic Connector Pull
Retracts a draw-bar in an automated connector assembly fixture, using its 81.7 N pull at 0.5 MPa to release the part safely.
Packaging Flap Retract
Pulls a mechanical latch back to clear carton flow on a packaging line, with the spring-extend fail-safe opening the path on air loss.
Textile Tension Release
Draws back a thread guide on a textile loom, relying on the 20mm stroke and fixed rubber bumper to cushion the rapid retraction.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X20U with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20U
To replace this MTAL20X20U, install the MTBL20X20U. Confirm the 20mm bore, 20mm stroke, G1/8 PT port, M8x1.25 rod thread, and flat U back cover. Because this SKU has no -S magnet, it cannot hold a sensor. The system requires a minimum of 0.2 MPa to overcome the return spring, and you must apply no external load on the spring-extend stroke.
If sizing up or down, the next size up is the 25mm bore, which raises the pull force to 137.2 N at 0.5 MPa. As the smallest available bore in this series, there is no smaller size down. Maintain a minimum 0.2 MPa operating pressure to ensure reliable retraction.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20U (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20U instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X20U FAQ
Yes, the MTAL20X20U is discontinued. The exact drop-in replacement is the MTBL20X20U, which matches the 20mm bore, 20mm stroke, G1/8 port, and flat U back cover.
It is a single-acting pull cylinder with a spring-extend fail-safe home. The usable pull force is 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa. It requires a minimum of 0.2 MPa to operate. Because this SKU lacks a magnet, it cannot accept a position sensor.
