This model is discontinued
AirTAC has phased out the MTAL series. You can still order this code here: we ship the direct replacement MTBL20X75U, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 MTAL20X75U
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X75U is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø20mm bore and 75mm 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 direct replacement is the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X75U.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X75U
The AirTAC MTAL20X75U is a discontinued single-acting pull-type mini cylinder with a 20mm bore and 75mm stroke. Air retracts the rod while an internal spring extends it, providing a fail-safe extended home position on air loss. It delivers a usable pull force of 81.7 N at 0.5 MPa. The direct replacement is the MTBL20X75U, matching the bore, stroke, force, and G1/8 port.
This U-back-cover SKU lacks a magnet and cannot take a position sensor. The original MTAL features threaded covers and a fixed rubber bumper, whereas the MTBL upgrade uses a riveted rolling-packed body. Never apply external load on the spring extend stroke. Operating pressure is 0.2-1.0 MPa with a speed range of 50-800 mm/s.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X75U Technical Specifications

| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X75U |
| Bore size | Ø20 mm |
| Stroke | 75 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X75U 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 MTAL20X75U Is Used
Textile Loom Tensioning
Pulls a thread tensioning lever back into position during loom operation, using the 81.7 N pull force at 0.5 MPa to maintain precise fabric tension.
Electronic Tester Probe
Retracts a spring-loaded test probe away from delicate PCB pads, using the fail-safe extended position to safely clear the board on air loss.
Packaging Flap Folder
Draws back a cardboard flap-folding blade on a cartonning machine, relying on the 75mm stroke and fixed rubber bumper for consistent end-stop positioning.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X75U with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X75U
Replace the MTAL20X75U with the MTBL20X75U. Confirm the 20mm bore, 75mm stroke, G1/8 port, PT thread, and U flat-end back cover. Because this SKU lacks the -S magnet, it cannot accept a sensor; the MTBL upgrade similarly requires no switch. Maintain a minimum 0.2 MPa working pressure to overcome the return spring. The fail-safe home is extended, and no external load should be applied to the spring extend stroke.
For sizing, step down to the 20mm bore if you need exactly 81.7 N at 0.5 MPa. Step up to the 32mm bore if you need greater pull force, which provides 261.2 N at 0.5 MPa. At this 75mm stroke, ensure mounting alignment to prevent rod side-loading and bending.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X75U (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X75U instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X75U FAQ
Yes, the MTAL20X75U is discontinued. The direct replacement is the MTBL20X75U, which matches the 20mm bore, 75mm stroke, U back cover, and G1/8 port. The MTBL features a riveted rolling-packed body instead of threaded covers.
The usable pull force is 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa (equating to a maximum of about 13.7 kgf). The fail-safe home is extended, meaning the internal spring pushes the rod out when air is lost. It requires a minimum of 0.2 MPa to retract the rod.
