This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X100SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X100SU 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 MTAL20X100SU
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X100SU is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø20mm bore and 100mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X100SU.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X100SU
The AirTAC MTAL20X100SU is a discontinued single-acting pull-type mini cylinder. Air retracts the rod, and an internal spring extends it. It delivers a usable pull force of 81.7 N at 0.5 MPa. The exact drop-in replacement is the MTBL20X100SU, matching the 20mm bore, 100mm stroke, and G1/8 port.
This SKU features a U flat-end back cover and a magnet for position sensing. The MTAL uses threaded covers and CS1-M or DS1-M switches, whereas the MTBL upgrade features a riveted rolling-packed body and CMSG, DMSG, or EMSG sensors. A fixed rubber bumper absorbs end-of-stroke impact, and the fail-safe home position is fully extended.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X100SU Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X100SU |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X100SU |
| Bore size | Ø20 mm |
| Stroke | 100 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X100SU 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 MTAL20X100SU Is Used
Injection Mould Ejection
Pulls a mould ejector pin back during injection. The 81.7 N pull at 0.5 MPa handles the load, and the spring-extend fail-safe parks the pin out safely.
Textile Loom Tensioning
Draws back a yarn tensioning guide on a loom. The 100mm stroke allows wide travel, while air retraction provides precise tension control.
Circuit Board Clamping
Retracts a hold-down clamp to release populated PCBs. The single-acting pull design requires only one air line, simplifying machine plumbing.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X100SU with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X100SU
To replace the MTAL20X100SU, specify the MTBL20X100SU. Confirm the 20mm bore, 100mm stroke, G1/8 port, M8x1.25 rod thread, U back cover, and the sensor family change from CS1-M/DS1-M to CMSG/DMSG/EMSG. Maintain a minimum 0.2 MPa operating pressure. The fail-safe home is extended, so apply no external load on the spring extend stroke.
For sizing, this 20mm bore yields 81.7 N pull at 0.5 MPa. Stepping up to the 25mm bore provides 137.2 N at 0.5 MPa. As 20mm is the smallest available, there is no smaller neighbour. At 100mm stroke, ensure your mounting resists side loads to prevent rod bending.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X100SU (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X100SU instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X100SU FAQ
Yes, the MTAL20X100SU is discontinued. The exact drop-in replacement is the MTBL20X100SU, matching the 20mm bore, 100mm stroke, U back cover, and G1/8 port. You will only need to update your sensors from CS1-M/DS1-M to the CMSG/DMSG/EMSG family.
The usable pull force is 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa (equivalent to 13.7 kgf). It requires a minimum 0.2 MPa operating pressure. The fail-safe home position is extended, meaning the spring pushes the rod out upon air loss.
