This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20CA 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 MTAL40X20CA
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X20CA is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø40mm bore and 20mm stroke, G1/4 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20CA.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X20CA
The AirTAC MTAL40X20CA is a discontinued single-acting pull-type mini cylinder with a 40mm bore and 20mm stroke. Air retracts the rod while an internal spring extends it, yielding a fail-safe extended home position. It delivers a usable pull force of 439.4 N at 0.5 MPa and 650.4 N at 0.7 MPa. The direct drop-in replacement is the MTBL40X20CA, which matches the 40mm bore, 20mm stroke, G1/4 port, and CA clevis mounting.
This MTAL40X20CA features a 16mm chrome-plated carbon-steel rod and an M12x1.25 rod-end thread. It uses a CA pivot clevis back cover that swings on a pin to accommodate arcing loads. Because this specific SKU lacks the -S magnet option, it cannot accept a position sensor. The original MTAL uses threaded covers and CS1-M/DS1-M sensors, whereas the MTBL upgrade features a riveted rolling-packed body and CMSG/DMSG/EMSG sensors.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X20CA Technical Specifications

| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20CA |
| Bore size | Ø40 mm |
| Stroke | 20 mm |
| Acting type | Single acting, pull (spring extend) |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20CA carries the same single-acting ratings.
Usable Pull Force (Ø40mm)
| Pressure | Pull force (net of spring) |
|---|---|
| 0.5 MPa | 439.4 N |
| 0.7 MPa | 650.4 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 MTAL40X20CA Is Used
Packaging Flap Folder
Pulls a mechanical folding arm during the carton sealing cycle. The 439.4 N pull force at 0.5 MPa easily overcomes cardboard resistance, and the CA clevis allows the arm to pivot smoothly.
Textile Beam Tensioner
Draws back a tensioning idler on a weaving loom. The spring-extended fail-safe home ensures the web tension is maintained if the 0.2 MPa minimum air supply drops.
Stamping Blank Ejector
Retracts a latch to release stamped metal blanks. The fixed rubber bumper absorbs the kinetic energy of the 16mm rod, preventing impact damage at the end of the 20mm pull stroke.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X20CA with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20CA
To replace an MTAL40X20CA, use the MTBL40X20CA. Confirm the 40mm bore, 20mm stroke, G1/4 port, PT thread, CA pivot clevis, and the lack of a magnet (this no-S SKU cannot take a sensor). The MTBL upgrade shifts from threaded covers to a riveted rolling-packed body. Both require a minimum operating pressure of 0.2 MPa. The fail-safe home is extended, and you must apply no external load on the spring extend stroke.
If sizing this 40mm bore, you can step down to the 32mm bore, which provides a 261.2 N pull force at 0.5 MPa. As the largest standard MAL bore, there is no larger neighbour in this mini series. The 20mm stroke is well within the 100mm maximum, so rod-bending side loads are not a primary concern for this short length.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20CA (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20CA instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X20CA FAQ
Yes, the MTAL40X20CA is discontinued. The exact drop-in replacement is the MTBL40X20CA, which matches the 40mm bore, 20mm stroke, CA clevis, and G1/4 port. The MTBL upgrades the body to a riveted rolling-packed design but maintains the same force class.
This single-acting pull cylinder has a usable pull force of 439.4 N at 0.5 MPa and 650.4 N at 0.7 MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor. The MTBL replacement uses CMSG/DMSG/EMSG sensors if you require position feedback.
