This model is discontinued
AirTAC has phased out the MTAL series. You can still order this code here: we ship the direct replacement MTBL20X30U, 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 MTAL20X30U
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30U is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø20mm bore and 30mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30U.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30U
The AirTAC MTAL20X30U is a discontinued single-acting pull-type mini cylinder with a 20mm bore and 30mm stroke. Air retracts the rod to do the work, while an internal spring extends it. The fail-safe home position is fully extended. It delivers a usable pull force of 81.7 N at 0.5 MPa. The direct replacement is the MTBL20X30U, matching the bore, stroke, U back cover, and G1/8 port.
This U-coded SKU has a flat-end back cover and uses a fixed rubber bumper. It lacks a magnet (-S), so it cannot take a position sensor. The MTAL features threaded covers and a carbon-steel rod with a 20 um hard chrome layer. Its replacement switches to a riveted rolling-packed body and CMSG/DMSG/EMSG sensors. Apply no external load on the spring extend stroke.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30U Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30U |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30U |
| Bore size | Ø20 mm |
| Stroke | 30 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30U 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 MTAL20X30U Is Used
Electronic Tester Probe
Uses the 81.7N pull at 0.5MPa to retract a test probe from populated PCB assemblies. The spring-extend fail-safe guarantees the probe lifts clear if shop air drops.
Packaging Flap Folder
Pulls a mechanical deflector to tuck carton flaps on a packaging line. The 30mm stroke provides precise motion, and the U flat-end cover mounts rigidly to the frame.
Textile Yarn Guide
Draws back a yarn tensioning guide out of the thread path. The 20mm bore offers compact spacing, while the spring-extend design parks the guide safely away during jams.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30U with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30U
To replace your MTAL20X30U, use the MTBL20X30U. Confirm the 20mm bore, 30mm stroke, G1/8 PT port, M8x1.25 rod-end thread, and U flat-end back cover. Because this SKU lacks the -S magnet, it cannot accept a CS1-M or DS1-M sensor; the MTBL upgrade uses CMSG/DMSG/EMSG switches. Remember the 0.2 MPa minimum working pressure and that the fail-safe home is extended.
If sizing up or down, the next size up is the 25mm bore (137.2 N pull at 0.5 MPa) for heavier tension. As the 20mm is the smallest available, stepping down requires a different mechanism. The fixed rubber bumper absorbs end-of-stroke shock but is not a lock.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30U (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30U instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30U FAQ
Yes, the MTAL20X30U is discontinued. The direct replacement is the MTBL20X30U. It matches the 20mm bore, 30mm stroke, U back cover, and G1/8 port. The MTAL uses threaded covers and CS1-M/DS1-M sensors, while the MTBL features a riveted rolling-packed body and CMSG/DMSG/EMSG sensors.
It is a single-acting pull cylinder, so air retracts the rod and a spring extends it. The fail-safe home position is extended. The usable pull force is 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa, with a maximum force of 134.4 N. It requires a minimum operating pressure of 0.2 MPa.
