This model is discontinued
AirTAC has phased out the MTAL series. You can still order this code here: we ship the direct replacement MTBL20X80SCM, 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 MTAL20X80SCM
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X80SCM 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80SCM.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X80SCM
The AirTAC MTAL20X80SCM 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 fully extended. It delivers a usable pull force of 81.7 N at 0.5 MPa. The direct replacement is the MTBL20X80SCM, matching the 20mm bore, 80mm stroke, and G1/8 port.
This SKU features a CM round-end back cover, an M8x1.25 rod-end thread, and a -S magnet compatible with CS1-M / DS1-M switches. The MTBL20X80SCM upgrade uses CMSG / DMSG / EMSG sensors and a riveted rolling-packed body instead of the MTAL's threaded covers. Both share a fixed rubber bumper. Never apply external load on the spring extend stroke.

| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80SCM 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 MTAL20X80SCM Is Used
Electronic Tester Probe Lift
Uses the 81.7N pull at 0.5MPa to retract a bed-of-nails test probe. The spring-extend fail-safe ensures the probe lifts clear of the PCB on air loss.
Packaging Flap Deflector
Pulls a deflector gate out of the carton path during transit. The 80mm stroke clears the packaging path before the spring extends it back to a safe home.
Lightweight Latch Withdrawal
Retracts an 8mm rod latch to release a small jig. The single-acting pull design needs only one 3/2 valve to manage the retraction cycle.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X80SCM with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80SCM
To replace this MTAL20X80SCM, order the MTBL20X80SCM. Confirm the 20mm bore, 80mm stroke, G1/8 port, PT thread, CM back cover, and FA mounting are retained. The -S magnet requires changing from CS1-M / DS1-M to CMSG / DMSG / EMSG switches. Maintain a 0.2 MPa minimum pressure and expect the fail-safe home to be extended.
If sizing down, the next available bore is not smaller than 20mm. If stepping up, the 25mm bore provides 137.2 N at 0.5 MPa. Since the 80mm stroke is close to the 100mm maximum, verify side-load conditions to prevent rod-bending.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80SCM (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X80SCM instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X80SCM FAQ
Yes, the MTAL20X80SCM is discontinued. The direct replacement is the MTBL20X80SCM, which matches the 20mm bore, 80mm stroke, and G1/8 port. The MTBL upgrade features a riveted rolling-packed body instead of threaded covers.
The usable pull force is 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa, with a maximum force of 134.4 N (approx 13.7 kgf). The fail-safe home is extended, meaning on air loss the internal spring pushes the rod out. It requires a 0.2 MPa minimum pressure to operate.
