This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X15CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X15CM 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 MTAL20X15CM
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X15CM is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø20mm bore and 15mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X15CM.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X15CM
The AirTAC MTAL20X15CM is a discontinued single-acting pull-type mini cylinder with a 20mm bore and 15mm stroke. Air retracts the rod, while an internal spring extends it, providing a fail-safe extended home position. It delivers a usable pull force of 81.7 N at 0.5 MPa. The direct drop-in replacement is the MTBL20X15CM, which matches the bore, stroke, CM round-end back cover, and G1/8 port.
This MTAL20X15CM SKU lacks the -S magnet option and cannot accept a position sensor. The older MTAL uses threaded covers and a CS1-M/DS1-M sensor track, while the MTBL upgrade features a riveted rolling-packed body and CMSG/DMSG/EMSG switches. It uses a fixed rubber bumper for end-of-stroke damping and requires a minimum 0.2 MPa operating pressure.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X15CM Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X15CM |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X15CM |
| Bore size | Ø20 mm |
| Stroke | 15 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X15CM 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 MTAL20X15CM Is Used
Electronic Connector Unlatching
Pulls a spring-loaded connector latch back 15mm to release the mating pair, using the 81.7N pull force to overcome friction.
Packaging Film Tensioning
Draws back a film tensioning arm in a vertical form-fill machine, relying on the fail-safe extended position to maintain tension on air loss.
Small Parts Ejector Gate
Retracts a small pneumatic ejection gate on a PCB router, allowing the internal spring to push the gate closed safely when compressed air drops.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X15CM with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X15CM
To replace this MTAL20X15CM, use the MTBL20X15CM drop-in. Confirm the 20mm bore, 15mm stroke, G1/8 PT port, M8x1.25 rod thread, and CM round-end back cover. Since this SKU has no magnet, you lose sensor capability; the MTBL also cannot take a sensor without the -S suffix. Remember the 0.2 MPa minimum pressure requirement and never apply an external load on the spring extend stroke, as the fail-safe home is extended.
If sizing up or down, the next size up is the 25mm bore, which provides 137.2 N of pull force at 0.5 MPa. The 20mm bore is the smallest available in this series. For any stroke at or above the 100mm maximum, you must account for potential rod-bending and side-load limitations.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X15CM (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X15CM instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X15CM FAQ
Yes, the MTAL20X15CM is discontinued. The exact drop-in replacement is the MTBL20X15CM, which matches the 20mm bore, 15mm stroke, CM cover, and G1/8 port. The MTBL upgrades the body to a riveted rolling-packed design.
