This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X100U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X100U 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 MTAL20X100U
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X100U 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X100U.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X100U
The AirTAC MTAL20X100U is a discontinued 20mm bore, 100mm stroke single-acting pull cylinder. Air retracts the rod while an internal spring extends it, making the fail-safe home position fully extended. It delivers a usable pull force of 81.7 N at 0.5 MPa. The exact drop-in replacement is the MTBL20X100U, matching the bore, stroke, G1/8 port, and U back cover.
This MTAL20X100U SKU lacks the -S magnet option, meaning it cannot accept a position sensor. The original MTAL uses threaded covers and a fixed rubber bumper for end-of-stroke damping. The MTBL20X100U upgrade shifts to a riveted rolling-packed body, maintaining the same 0.2-1.0 MPa operating pressure and 50-800 mm/s speed range.

| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X100U 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 MTAL20X100U Is Used
Injection Mould Ejection
Pulls a secondary ejector pin back inside the mould cavity during plastic injection. The spring-extended fail-safe ensures the pin stays out if plant air drops, preventing short shots.
PCB Test Socket Release
Retracts a latch holding a spring-loaded test fixture open. The 81.7 N pull at 0.5 MPa is sufficient to overcome the fixture tension and draw the mechanism clear.
Pneumatic Gripper Draw-Back
Pulls a small tooling head back 100mm out of a machining zone. The fixed rubber bumper absorbs the shock at the end of the air retraction stroke.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X100U with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X100U
To replace the MTAL20X100U, install the MTBL20X100U. Confirm the 20mm bore, 100mm stroke, G1/8 port, PT thread, and U flat-end back cover. Because this MTAL has no -S magnet, it cannot take a sensor; if you need sensing on the MTBL, specify the -S option to use CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. Maintain the 0.2 MPa minimum operating pressure and apply no external load on the spring extend stroke. At 100mm stroke, watch for rod bending under side loads.
If sizing up or down, the next size up is the 25mm bore, yielding 137.2 N of pull at 0.5 MPa. As the smallest standard bore in this series, there is no smaller neighbour to step down to.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X100U (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X100U instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X100U FAQ
Yes, the MTAL20X100U is discontinued. The exact drop-in replacement is the MTBL20X100U, which matches the 20mm bore, 100mm stroke, G1/8 port, and U back cover. The MTBL upgrades the body to a riveted rolling-packed design.
The 20mm bore single-acting pull force is 2.6 N at 0.2 MPa, 81.7 N at 0.5 MPa, and 134.4 N at 0.7 MPa. The maximum standard stroke is 100mm. Operating pressure is 0.2-1.0 MPa, and the fail-safe home position is extended.
