This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30SCM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30SCM in place of this model. 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 MTAL20X30SCM
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30SCM 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 drop-in replacement is the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30SCM.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30SCM
The AirTAC MTAL20X30SCM is a discontinued single-acting pull-type mini cylinder. Air retracts the rod, while an internal spring extends it. Fail-safe home is extended. It delivers 81.7 N usable pull at 0.5 MPa. The exact drop-in replacement is the MTBL20X30SCM.
This 20mm bore unit has an 8mm rod, M8x1.25 thread, and a G1/8 PT port. It includes a CM round-end back cover and a -S magnet. The MTAL uses threaded covers and CS1-M/DS1-M sensors; the MTBL upgrade features a riveted body and CMSG/DMSG/EMSG sensors. It uses a fixed rubber bumper.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30SCM Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30SCM |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30SCM |
| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30SCM 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 MTAL20X30SCM Is Used
PCB Router Spindle Brake
Retracts a locking pin from a depaneling router spindle using 81.7 N at 0.5 MPa; the spring-extend fail-safe relocks the spindle brake instantly on air loss.
Pick-and-Head Latch
Pulls open a vacuum nozzle latch on a SMT pick-and-place head; the spring extends the rod to secure the latch when the 3/2 valve exhausts.
Test Fixture Clamp
Draws back a wire-form clamp on an electronics test fixture; the spring-extended home position safely releases the part between test cycles.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30SCM with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30SCM
Replace this MTAL20X30SCM with the MTBL20X30SCM. Confirm the 20mm bore, 30mm stroke, G1/8 port, and CM cover match. The MTBL keeps the -S magnet but changes sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG. Both require 0.2 MPa minimum air. Never apply external load on the spring extend stroke.
If you need less force, no smaller bore exists. To step up, the 25mm bore offers 137.2 N at 0.5 MPa. This 30mm stroke is under the 100mm max, avoiding rod-bending side-load risks.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30SCM (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30SCM instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30SCM FAQ
Yes, the MTAL20X30SCM is discontinued. The exact drop-in replacement is the MTBL20X30SCM, matching the 20mm bore, 30mm stroke, G1/8 port, and CM cover. The MTBL upgrade uses a riveted body and CMSG/DMSG/EMSG sensors instead of threaded covers and CS1-M/DS1-M switches.
This single-acting pull cylinder provides 81.7 N usable pull at 0.5 MPa and 134.4 N at 0.7 MPa. Operating pressure is 0.2-1.0 MPa (min 0.2 MPa). It has a fixed rubber bumper, no adjustable cushion, and cannot hold a mid-stroke load without an external device.
