This model is discontinued
AirTAC has phased out the MTAL series. You can still order this code here: we ship the direct replacement MTBL20X80CM, 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 MTAL20X80CM
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X80CM is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø20mm bore and 80mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80CM.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X80CM
The AirTAC MTAL20X80CM is a discontinued single-acting pull-type mini cylinder with a 20mm bore and 80mm stroke. Air retracts the rod while an internal spring extends it. It delivers a usable pull force of 81.7N at 0.5MPa. The direct replacement is the MTBL20X80CM, matching the bore, stroke, and G1/8 port.
This MTAL20X80CM variant features a CM round-end back cover and a fixed rubber bumper. It has no -S magnet, meaning it cannot take a position sensor. The original uses threaded covers, while the MTBL upgrade features a riveted rolling-packed body for greater durability. On air loss, the fail-safe home is extended. Apply no external load on the spring extend stroke.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X80CM Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X80CM |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80CM |
| Bore size | Ø20 mm |
| Stroke | 80 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80CM 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 MTAL20X80CM Is Used
Electronic Tester Trays
Pulls spring-loaded test probes away from PCBs. The 81.7N pull at 0.5MPa retracts the tray, and the spring-extended fail-safe safely parks the probes out when air drops.
Packaging Film Tensioner
Draws back a web-tensioning roller on a vertical form-fill-seal machine. The 20mm bore provides light tension, while the CM round-end cover allows compact pivot mounting.
Small Part Ejector
Pulls a tiny plastic detent back to release stamped micro-covers from a die. The fixed rubber bumper absorbs the 80mm stroke impact without requiring adjustment.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X80CM with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80CM
To replace the MTAL20X80CM, confirm the 20mm bore, 80mm stroke, G1/8 port, PT thread, and CM round-end cover on the MTBL20X80CM. Because this SKU lacks the -S magnet, it cannot accept a sensor; the MTBL upgrade uses CMSG/DMSG/EMSG switches if you need position feedback. Remember the 0.2MPa minimum working pressure and that the fail-safe home is extended.
For sizing both ways: stepping down is not an option as 20mm is the smallest available bore. Stepping up to the 32mm bore yields a higher 261.2N pull at 0.5MPa. At 80mm stroke, keep the rod guided to prevent side-load and rod-bending issues.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80CM (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80CM instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X80CM FAQ
Yes, the MTAL20X80CM is discontinued. The direct replacement is the MTBL20X80CM, which matches the 20mm bore, 80mm stroke, and G1/8 port. The MTBL upgrades the body to a riveted rolling-packed design.
The usable pull force is 81.7N at 0.5MPa and 134.4N at 0.7MPa (max 13.7 kgf). It is a single-acting pull cylinder where air retracts the rod and the spring extends it. The fail-safe home is extended, requiring a 0.2MPa minimum pressure.
