This model is discontinued
AirTAC has phased out the MTAL series. You can still order this code here: we ship the direct replacement MTBL20X5U, 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 MTAL20X5U
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X5U is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø20mm bore and 5mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X5U.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X5U
The AirTAC MTAL20X5U is a discontinued single-acting pull-type mini cylinder with a 20mm bore and 5mm stroke. Air retracts the rod while an internal spring extends it, yielding a fail-safe extended home position. It delivers 81.7 N of usable pull force at 0.5 MPa. The direct replacement is the MTBL20X5U, matching bore, stroke, U back cover, and G1/8 port.
This U-model features a flat-end rear cover and lacks the -S magnet option, meaning it cannot accept CS1-M or DS1-M position sensors. The MTAL uses threaded covers and a fixed rubber bumper, whereas the MTBL upgrade features a riveted rolling-packed body. Never apply external loads to the spring extend stroke.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X5U Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X5U |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X5U |
| Bore size | Ø20 mm |
| Stroke | 5 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X5U 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 MTAL20X5U Is Used
Electronic Tester Probe
Pulls a 5mm test probe away from populated PCB arrays using 81.7 N at 0.5 MPa, using the spring-extend fail-safe to guarantee probe retraction on air loss.
IC Tray Escapement
Retracts a thin latch pin to release semiconductor chip trays, relying on the short 5mm stroke and fixed rubber bumper for precise, shock-free positioning.
Small Part Ejector
Draws back a tiny pneumatic finger in a watch-movement assembly press, ensuring the gripper opens safely when compressed air is removed.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X5U with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X5U
Replace this MTAL20X5U with the MTBL20X5U. Confirm the 20mm bore, 5mm stroke, G1/8 PT port, M8x1.25 rod thread, and U flat-end back cover. Because this SKU lacks the -S magnet, it cannot take a sensor; the MTBL upgrade similarly requires no switch. Maintain a 0.2 MPa minimum working pressure and expect the fail-safe home to be extended.
For sizing, step down if force is marginal or step up if you need more pull. The next size up is the 25mm bore, providing 137.2 N at 0.5 MPa. As the smallest standard bore, the 20mm is your floor option. With this short 5mm stroke, avoid side loads to prevent rod-bending and premature seal wear.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X5U (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X5U instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X5U FAQ
Yes, the MTAL20X5U is discontinued. The direct replacement is the MTBL20X5U, matching the 20mm bore, 5mm stroke, U back cover, and G1/8 port. The MTBL upgrades the body to a riveted rolling-packed design.
It is a single-acting pull cylinder where air retracts the rod and the spring extends it. The fail-safe home is extended. It provides 81.7 N of usable pull force at 0.5 MPa, 134.4 N at 0.7 MPa, and requires a 0.2 MPa minimum working pressure.
