This model is discontinued
AirTAC has phased out the MTAL series. You can still order this code here: we ship the direct replacement MTBL20X25SCA, 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 MTAL20X25SCA
The AirTAC MTAL Rear Single Acting Mini Cylinder MTAL20X25SCA 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25SCA.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X25SCA
The AirTAC MTAL20X25SCA is a discontinued single-acting pull-type mini cylinder with a 20mm bore and 25mm stroke. Air retracts the rod while an internal spring extends it, yielding a usable pull force of 81.7 N at 0.5 MPa. The direct replacement is the MTBL20X25SCA, matching the bore, stroke, G1/8 port, and CA pivot cover.
This SKU includes the -S magnet for CS1-M/DS1-M switches, which upgrades to CMSG/DMSG/EMSG sensors on the MTBL. The MTAL uses threaded covers, whereas the MTBL features a riveted rolling-packed body. A fixed rubber bumper absorbs end-of-stroke impact, and the CA back cover swings on a pin for arcing loads. Never apply external load to the unpowered spring-extend stroke.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X25SCA Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X25SCA |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25SCA |
| Bore size | Ø20 mm |
| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25SCA 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 MTAL20X25SCA Is Used
Lathe Chuck Unclamping
Pulls the drawbar back to release a lathe chuck jaw, using the 81.7 N pull force at 0.5 MPa, with the spring safely pushing the mechanism outward on air loss.
PCB Test Socket Release
Retracts a test probe holder during board testing; the fail-safe extended position prevents board crushing if compressed air drops.
Pivot Gate Latching
Uses the CA clevis pin to swing with the arc of a packaging machine gate latch, pulling the pin clear at 0.5 MPa and springing it back to lock.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X25SCA with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25SCA
To replace this MTAL20X25SCA with the MTBL20X25SCA, verify the 20mm bore, 25mm stroke, PT G1/8 port, M8x1.25 rod thread, and CA pivot back cover. The -S magnet switches from CS1-M/DS1-M to CMSG/DMSG/EMSG sensors. Operating pressure must be at least 0.2 MPa, and the fail-safe home is EXTENDED.
If sizing up or down, the next size up is the 25mm bore offering 137.2 N pull at 0.5 MPa. As the smallest standard bore, there is no smaller size, so for loads under 81.7 N, confirm mechanical leverage from the datasheet. Maintain a minimum 0.2 MPa air supply to overcome the return spring.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25SCA (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25SCA instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X25SCA FAQ
Yes, the MTAL20X25SCA is discontinued. The direct replacement is the MTBL20X25SCA, matching the 20mm bore, 25mm stroke, G1/8 port, and CA cover. The MTBL upgrades the -S magnet to CMSG/DMSG/EMSG sensors and uses a riveted rolling-packed body instead of threaded covers.
It is a single-acting pull cylinder, so air retracts the rod and the spring extends it. The usable pull force is 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa (8.3 kgf max). Operating pressure is 0.2-1.0 MPa, speed is 50-800 mm/s, and the fail-safe home is extended.
