This model is discontinued
AirTAC has phased out the MTAL series. You can still order this code here: we ship the direct replacement MTBL20X30CA, 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 MTAL20X30CA
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30CA 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30CA.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30CA
The AirTAC MTAL20X30CA is a discontinued single-acting pull-type mini cylinder. Air retracts the 8mm rod to do the work, while an internal spring extends it back out when air is released. The direct replacement is the MTBL20X30CA, matching the 20mm bore, 30mm stroke, and CA clevis. This 20mm bore provides a usable pull force of 81.7 N at 0.5 MPa.
This CA version features a back cover pivot clevis that swings on a pin to absorb arcing loads. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor. When upgrading to the MTBL, note the construction shifts from threaded covers to a riveted rolling-packed body, and the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG if you ever need one. The fixed rubber bumper absorbs end-of-stroke impact.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30CA Technical Specifications

| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30CA |
| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30CA 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 MTAL20X30CA Is Used
Packaging Flap Pull-down
Retracts a guide arm to tuck carton flaps on a packaging line, using the 81.7 N pull at 0.5 MPa to clear the path before sealing.
PCB Test Drawer Retract
Pulls a sliding test tray out of a testing fixture; the spring-extended fail-safe ensures the tray parks open safely during a power loss.
Textile Tension Release
Draws back a yarn tensioning pulley on a weaving machine, relying on the CA pivot clevis to accommodate slight angular misalignment.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30CA with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30CA
To replace the MTAL20X30CA, specify the MTBL20X30CA to match the 20mm bore, 30mm stroke, G1/8 PT port, M8x1.25 rod thread, and CA pivot cover. The system needs a 3/2 valve and a minimum 0.2 MPa operating pressure. Remember the fail-safe home is extended, and apply no external load on the spring extend stroke. If sizing alternatives, stepping down is not an option as 20mm is the smallest, but stepping up to the 25mm bore yields 137.2 N of pull force at 0.5 MPa for heavier loads.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30CA (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30CA instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30CA FAQ
Yes, the MTAL20X30CA is discontinued. The direct replacement is the MTBL20X30CA, which matches the 20mm bore, 30mm stroke, CA pivot cover, and G1/8 port. The MTBL upgrades the body to a riveted rolling-packed design but retains the same force class.
It is a single-acting pull cylinder with a spring-extend fail-safe, meaning air retracts the rod and the spring pushes it back out on air loss. The usable pull force is 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa, requiring a minimum 0.2 MPa to operate. This SKU has no magnet, so it cannot take a sensor.
