This model is discontinued
AirTAC has phased out the MTAL series. You can still order this code here: we ship the direct replacement MTBL20X25SU, 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 MTAL20X25SU
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X25SU is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø20mm bore and 25mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25SU.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X25SU
The AirTAC MTAL20X25SU is a discontinued single-acting pull, spring-extend mini cylinder. Air retracts the 8mm rod for the work stroke, while an internal spring extends it back out. It provides a usable pull force of 81.7 N at 0.5 MPa. The direct replacement is the MTBL20X25SU, matching the 20mm bore, 25mm stroke, G1/8 port, and U flat-end back cover.
This MTAL20X25SU features a -S magnet for CS1-M or DS1-M switches; the MTBL upgrade uses CMSG, DMSG, or EMSG sensors. MTAL cylinders use threaded covers, whereas the MTBL replacement features a riveted rolling-packed body. End-of-stroke damping relies on a fixed rubber bumper. The fail-safe home position is extended, meaning on air loss the spring pushes the rod out.

| Stroke | 25 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25SU 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 MTAL20X25SU Is Used
Injection Mold Ejection
Pulls a small plastic ejector pin back inside the mold cavity during material injection. The 81.7 N pull at 0.5 MPa retracts the 8mm rod, and the spring-extend fail-safe pushes the pin out if air drops.
Packaging Flap Tensioning
Draws back a carton sealing arm to maintain web tension. The 25mm stroke provides compact travel, and the fixed rubber bumper absorbs the impact when the rod reaches the retracted position.
PCB Test Probe Lift
Retracts a bed-of-nails test probe away from the circuit board. The single-acting pull design requires only one 3/2 valve line, simplifying the test fixture's pneumatic plumbing.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X25SU with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25SU
To replace the MTAL20X25SU, install the MTBL20X25SU. Confirm the 20mm bore, 25mm stroke, PT G1/8 port, M8x1.25 rod-end thread, U flat-end back cover, and the -S magnet (noting the switch change to CMSG/DMSG/EMSG). Maintain a minimum 0.2 MPa operating pressure. Apply no external load on the spring extend stroke, as the fail-safe home is extended.
For sizing flexibility, step down to the next smaller bore if available, or step up to the 25mm bore which yields 137.2 N of pull at 0.5 MPa. This MTAL20X25SU provides 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25SU (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25SU instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X25SU FAQ
Yes, the MTAL20X25SU is discontinued. The direct replacement is the MTBL20X25SU, matching the 20mm bore, 25mm stroke, G1/8 port, U back cover, and magnet. The MTBL uses a riveted body instead of threaded covers, and its magnet works with CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M.
The usable pull force is 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa. It is a single-acting pull cylinder where air retracts the rod and a spring extends it. The fail-safe home position is extended, meaning on air loss the spring pushes the rod out. It requires a minimum of 0.2 MPa to operate.
