This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25U 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 MTAL20X25U
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X25U is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø20mm bore and 25mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25U.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X25U
The AirTAC MTAL20X25U is a discontinued single-acting pull-type mini cylinder. Air retracts the 8mm rod, while an internal spring extends it. The fail-safe home is extended. It delivers a usable pull force of 81.7 N at 0.5 MPa. The exact drop-in replacement is the MTBL20X25U, matching the 20mm bore, 25mm stroke, and G1/8 port.
This U-back-cover SKU lacks the -S magnet, so it cannot take a position sensor. The MTAL uses threaded covers and a CS1-M/DS1-M sensor family, while the MTBL upgrade features a riveted rolling-packed body and CMSG/DMSG/EMSG sensors. It uses a fixed rubber bumper and a hard-chrome carbon-steel rod.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X25U Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X25U |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25U |
| Bore size | Ø20 mm |
| Stroke | 25 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25U 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 MTAL20X25U Is Used
Thermoformer Drawer Latch
Pulls a plastic-sheet clamping drawer back on a small thermoforming line. The 81.7 N pull at 0.5 MPa securely retracts the latch, and the spring-extend fail-safe releases the clamp on air loss.
PCB Router Gate Drawback
Retracts a safety gate on a PCB depaneling router. The compact 20mm bore fits tight electronics enclosures, drawing the barrier back to allow board unloading before spring-extending closed.
Textile Tension Release
Pulls a fabric tensioning idler arm back during a textile machine bobbin change. The 25mm stroke clears the yarn path, and the spring-extended fail-safe ensures the arm parks out safely.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X25U with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25U
To replace this MTAL20X25U, specify the MTBL20X25U. Confirm the 20mm bore, 25mm stroke, G1/8 port, PT thread, and U flat-end back cover. Because this SKU has no magnet, you lose any switch mounting; the MTBL upgrade moves to CMSG/DMSG/EMSG sensors. Remember the 0.2 MPa minimum working pressure and apply no external load on the spring-extend stroke.
If sizing up or down, the next size up is the 25mm bore, providing 137.2 N of pull at 0.5 MPa. As the smallest available bore, 20mm is your floor. At 25mm stroke, side-load risk is minimal, but ensure rigid front and U-cover mounting to prevent rod binding.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25U (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25U instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X25U FAQ
Yes, the MTAL20X25U is discontinued. The exact drop-in replacement is the MTBL20X25U. It matches the 20mm bore, 25mm stroke, G1/8 port, and U back cover. The MTBL upgrades the body to a riveted rolling-packed design and uses CMSG/DMSG/EMSG sensors instead of the older CS1-M/DS1-M.
It is a single-acting pull cylinder, so air retracts the rod and a 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. It requires a minimum of 0.2 MPa to operate, and you must apply no external load on the spring-extend stroke.
