This model is discontinued
AirTAC has phased out the MTAL series. You can still order this code here: we ship the direct replacement MTBL20X30SCA, 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 MTAL20X30SCA
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30SCA is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø20mm bore and 30mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30SCA.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30SCA
The AirTAC MTAL20X30SCA is a discontinued single-acting pull cylinder with a 20mm bore and 30mm stroke. Air retracts the rod while an internal spring extends it, yielding a fail-safe extended home position. It delivers a usable pull force of 81.7 N at 0.5 MPa. The direct replacement is the MTBL20X30SCA, matching bore, stroke, and force.
This -S model includes a magnet for CS1-M or DS1-M switches, whereas the MTBL replacement uses CMSG, DMSG, or EMSG sensors. The MTAL features threaded covers and a fixed rubber bumper, while the MTBL upgrades to a riveted rolling-packed body. The CA back cover provides a pivot clevis for arcing loads. Never apply external load on the spring extend stroke.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30SCA Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30SCA |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30SCA |
| Bore size | Ø20 mm |
| Stroke | 30 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30SCA 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 MTAL20X30SCA Is Used
Packaging Flap Tucking
Uses 81.7 N at 0.5 MPa to retract and tuck cardboard flaps on a carton closing machine, relying on the spring-extended fail-safe to clear the path during air loss.
Textile Latch Release
Pulls a tension latch on a weaving loom; the CA pivot clevis accommodates arcing motion, while the single-acting pull mechanism simplifies valve plumbing.
Electronic Gripper Open
Draws back a small electronic component gripper jaw; the M8x1.25 rod end threads directly into the jaw, using the spring to safely open the gripper on air loss.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30SCA with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30SCA
To replace the MTAL20X30SCA with the MTBL20X30SCA, confirm the 20mm bore, 30mm stroke, G1/8 port, PT thread, CA pivot clevis, and -S magnet. Note the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. Maintain the 0.2 MPa minimum operating pressure and remember the fail-safe home is extended. If sizing down, the 20mm bore is the smallest available. If stepping up, the 25mm bore provides 137.2 N of pull force at 0.5 MPa. With a 30mm stroke, side-load and rod-bending risks are minimal.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30SCA (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30SCA instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30SCA FAQ
Yes, the MTAL20X30SCA is discontinued. The direct replacement is the MTBL20X30SCA, matching the 20mm bore, 30mm stroke, CA pivot cover, and force class. You only need to update your sensors from the older CS1-M/DS1-M switches to the MTBL's CMSG/DMSG/EMSG family.
It is a single-acting pull cylinder operating from 0.2 to 1.0 MPa. The usable pull force is 2.6 N at 0.2 MPa, 55.3 N at 0.4 MPa, 81.7 N at 0.5 MPa, and 134.4 N at 0.7 MPa. The maximum standard stroke is 100 mm.
