This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X40CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X40CA 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 MTAL20X40CA
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X40CA is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø20mm bore and 40mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X40CA.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X40CA
The AirTAC MTAL20X40CA is a discontinued single-acting pull-type mini cylinder with a 20 mm bore and 40 mm stroke. Air retracts the rod, while an internal spring extends it, meaning the fail-safe home position is fully extended. It delivers a usable pull force of 81.7 N at 0.5 MPa. The exact drop-in replacement is the MTBL20X40CA, which matches the bore, stroke, CA pivot cover, and G1/8 port.
This SKU has no magnet and cannot take a position sensor, whereas upgrading to the MTBL allows CMSG/DMSG/EMSG switches if needed later. The MTAL uses threaded covers and a fixed rubber bumper, while the MTBL replacement features a riveted rolling-packed body. Apply no external load on the spring extend stroke to avoid damaging the internal return mechanism.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X40CA Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X40CA |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X40CA |
| Bore size | Ø20 mm |
| Stroke | 40 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X40CA 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 MTAL20X40CA Is Used
Textile Loom Tension Release
Uses the 81.7 N pull at 0.5 MPa to retract a yarn tensioning arm during loom stoppages, letting the internal spring safely extend and slacken the thread upon air loss.
PCB Router Clamp Drawback
Pulls a small machining fixture back on a 40 mm stroke to clear the cutting area, relying on the fixed rubber bumper to absorb end-of-stroke shock without adjustable cushioning.
Gate Valve Limiter Reset
Retracts a mechanical stopper pin out of a fluid flow path when pressurized, with the spring-extended fail-safe home pushing the pin back out to lock the valve during an air failure.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X40CA with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X40CA
To replace this MTAL20X40CA, order the MTBL20X40CA. Confirm your 20 mm bore, 40 mm stroke, G1/8 port, PT thread, CA pivot back cover, and the lack of a magnet. Remember the 0.2 MPa minimum working pressure and that the fail-safe home is extended. Stepping down is not an option as 20 mm is the smallest available bore. If you need more force, step up to the 25 mm bore, which provides 137.2 N of usable pull at 0.5 MPa. Because the 40 mm stroke is below the 100 mm maximum, rod-bending side loads are minimal, but always ensure the CA clevis pin swings freely to absorb arcing loads.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X40CA (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X40CA instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X40CA FAQ
Yes, the MTAL20X40CA is discontinued. The exact drop-in replacement is the MTBL20X40CA, which matches the 20 mm bore, 40 mm stroke, CA pivot cover, and G1/8 port. The MTBL upgrade uses a riveted rolling-packed body instead of threaded covers.
It is a single-acting pull cylinder where air retracts and spring extends, so 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 has no push force, requires a 0.2 MPa minimum pressure, and this specific SKU lacks a magnet so it cannot take a CS1-M or DS1-M sensor.
