This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50CA 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 MTAL20X50CA
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X50CA is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø20mm bore and 50mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50CA.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X50CA
The AirTAC MTAL20X50CA is a discontinued single-acting pull-type mini cylinder. Air retracts the rod, while an internal spring extends it, meaning the fail-safe home position is extended. This 20 mm bore, 50 mm stroke SKU provides a usable pull force of 81.7 N at 0.5 MPa. The direct drop-in replacement is the MTBL20X50CA, matching the bore, stroke, CA clevis, and G1/8 port.
This non-magnet SKU cannot accept a position sensor. Upgrading to the MTBL moves from the MTAL's threaded covers to a riveted rolling-packed body. If you previously used a magnet-equipped MTAL-S, note the sensor family changes from CS1-M / DS1-M to CMSG / DMSG / EMSG. The fixed rubber bumper absorbs end-of-stroke impact, and you must never apply an external load on the unpowered spring-extend stroke.

| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50CA 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 MTAL20X50CA Is Used
Packaging Flap Pull-in
Retracts a carton sealing flap on a packaging line. The 81.7 N pull at 0.5 MPa is sufficient for light cardboard, and the spring-extended fail-safe clears the path on air loss.
Textile Tension Release
Draws back a fabric guide bar on a weaving machine. The CA clevis accommodates the slight arc of the mechanism, while the single-acting design saves on valving.
Electronic Tester Disconnect
Pulls a spring-loaded test probe away from a PCB. The fixed rubber bumper ensures a soft retraction stop, preventing damage to delicate board traces.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X50CA with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50CA
To replace this MTAL20X50CA, order the MTBL20X50CA. Confirm the 20 mm bore, 50 mm stroke, G1/8 PT port, M8x1.25 rod thread, and CA pivot back cover. 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 MAL bore. Stepping up to the 32 mm bore yields 261.2 N of pull force at 0.5 MPa, useful if your 81.7 N is insufficient. The 50 mm stroke is well under the 100 mm standard limit, so rod bending is minimal, but always avoid side loads.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50CA (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50CA instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X50CA FAQ
Yes, the MTAL20X50CA is discontinued. The exact drop-in replacement is the MTBL20X50CA, which matches the 20 mm bore, 50 mm stroke, CA back cover, and G1/8 port. The MTBL features a riveted rolling-packed body instead of the MTAL's threaded covers.
This single-acting pull cylinder provides a usable pull force of 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa (maximum 13.7 kgf). It operates on 0.2-1.0 MPa pressure with a speed of 50-800 mm/s. Air retracts the rod, and the spring extends it to the fail-safe home position.
