This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X35U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X35U 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 MTAL20X35U
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X35U is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø20mm bore and 35mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X35U.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X35U
The AirTAC MTAL20X35U is a discontinued single-acting pull-type mini cylinder with a 20mm bore and 35mm stroke. Air retracts the rod while an internal spring extends it, yielding a fail-safe extended home position. It delivers a usable pull force of 81.7 N at 0.5 MPa. The exact drop-in replacement is the MTBL20X35U, matching the bore, stroke, force, and port.
This U-back-cover SKU has no magnet and cannot take a position sensor. The MTAL features threaded covers and fixed rubber bumpers, whereas the MTBL upgrade uses a riveted rolling-packed body. If you previously used the -S magnet variant, the older CS1-M/DS1-M switches are replaced by CMSG/DMSG/EMSG sensors on the MTBL. Never apply an external load to the spring extend stroke.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X35U Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X35U |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X35U |
| Bore size | Ø20 mm |
| Stroke | 35 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X35U 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 MTAL20X35U Is Used
Electronic Tester Extraction
Pulls a loaded test socket carriage back on a PCB validation rig, using the 81.7 N pull force at 0.5 MPa to retract against a probe array.
Pick-and-Place Arm Park
Retracts a secondary micro-gripper arm on a SMT nozzle changer, relying on the spring-extended fail-safe to keep the arm clear during an air-loss event.
Small Door Latch Withdrawal
Draws back a spring-loaded access panel latch on a semiconductor inspection hood, using the 35mm stroke to clear the strike before opening.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X35U with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X35U
To replace the MTAL20X35U with the MTBL20X35U, confirm the 20mm bore, 35mm stroke, G1/8 port, PT thread, and flat-end U back cover. Because this SKU lacks the -S magnet, it cannot accept a position sensor. The MTBL upgrade provides identical ratings but changes the body construction from threaded covers to a riveted rolling-packed design. Operating pressure must be at least 0.2 MPa to overcome the return spring.
When sizing, step up to the 32mm bore for 261.2 N of pull force at 0.5 MPa if 81.7 N is insufficient. As the 20mm bore is the smallest available, there is no smaller option. Remember that the fail-safe home is extended, and you must apply no external load to the spring extend stroke.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X35U (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X35U instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X35U FAQ
Yes, the MTAL20X35U is discontinued. The exact drop-in replacement is the MTBL20X35U, which matches the 20mm bore, 35mm stroke, 81.7 N pull force at 0.5 MPa, and G1/8 port. The MTBL upgrades the threaded covers to a riveted rolling-packed body.
The usable pull force is 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa (8.3 kgf max). The minimum operating pressure is 0.2 MPa. It is a single-acting pull cylinder, so air retracts the rod and the internal spring extends it. On air loss, the fail-safe home position is fully extended.
