This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30CM 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 MTAL20X30CM
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30CM 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30CM.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30CM
The AirTAC MTAL20X30CM is a discontinued single-acting pull-type mini cylinder. Air retracts the rod, while an internal spring extends it. The fail-safe home is extended. It delivers a usable pull force of 81.7 N at 0.5 MPa. The exact drop-in replacement is the MTBL20X30CM.
This 20 mm bore unit uses a G1/8 port and an M8x1.25 rod thread. It features a CM round-end back cover. The MTAL has threaded covers, while the MTBL replacement uses a riveted rolling-packed body. This SKU lacks a magnet, so it cannot take a position sensor. It uses a fixed rubber bumper.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30CM Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30CM |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30CM |
| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30CM 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 MTAL20X30CM Is Used
Textile Loom Tension Release
Pulls a yarn tensioner back to clear the thread path. The 81.7 N pull at 0.5 MPa handles the drag, while the spring-extend fail-safe parks the guide out of the way on air loss.
PCB Router Gate Retract
Draws a routing guide pin clear of the cutting head. The 30 mm stroke retracts the pin on signal, and the fixed rubber bumper absorbs the end-of-stroke impact.
Small Part Ejector Clear
Pulls an ejection latch back to release stamped micro-parts. The single-acting design uses one 3/2 valve, simplifying the machine's pneumatic routing.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30CM with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30CM
Replace this MTAL20X30CM with the MTBL20X30CM. Confirm the 20 mm bore, 30 mm stroke, G1/8 port, PT thread, and CM round-end cover. The MTBL matches the force and port. Because this MTAL has no -S magnet, it cannot accept a sensor. The MTBL upgrade also changes the switch family from CS1-M/DS1-M to CMSG/DMSG/EMSG if you need detection later.
Check the 0.2 MPa minimum working pressure. Apply no external load on the spring extend stroke. Stepping down is not an option as 20 mm is the smallest bore. Stepping up to the 32 mm bore gives a higher 261.2 N pull at 0.5 MPa for heavier draw-back tasks.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30CM (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X30CM instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X30CM FAQ
Yes, the MTAL20X30CM is discontinued. The exact drop-in replacement is the MTBL20X30CM. It shares the 20 mm bore, 30 mm stroke, 81.7 N pull force at 0.5 MPa, G1/8 port, and CM mounting. The MTBL upgrades the body to a riveted rolling-packed design.
It is a single-acting pull cylinder, so air retracts the rod and the spring extends it. The fail-safe home is extended. The usable pull force is 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa. The maximum force is 13.7 kgf at 1.0 MPa. It requires a minimum of 0.2 MPa to operate.
