This model is discontinued
AirTAC has phased out the MTAL series. You can still order this code here: we ship the direct replacement MTBL32X50U, 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 MTAL32X50U
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL32X50U is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø32mm bore and 50mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL32X50U.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL32X50U
The AirTAC MTAL32X50U is a discontinued single-acting pull-type mini cylinder with a 32 mm bore and 50 mm stroke. Air retracts the rod to perform work, while an internal spring extends it back out. It delivers a usable pull force of 261.2 N at 0.5 MPa. The direct replacement is the MTBL32X50U, matching the bore, stroke, force, and porting.
This U-back-cover SKU lacks the -S magnet option, so it cannot accept a position sensor. Upgrading to the MTBL brings a riveted rolling-packed body instead of the MTAL's threaded covers. The spring-extend design means the fail-safe home position is fully extended, and no external load should be applied to the spring stroke for safety.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL32X50U Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL32X50U |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL32X50U |
| Bore size | Ø32 mm |
| Stroke | 50 mm |
| Acting type | Single acting, pull (spring extend) |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL32X50U carries the same single-acting ratings.
Usable Pull Force (Ø32mm)
| Pressure | Pull force (net of spring) |
|---|---|
| 0.5 MPa | 261.2 N |
| 0.7 MPa | 399.4 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 MTAL32X50U Is Used
Injection Mold Core Pull
Retracts a 32 mm mold core during the injection cooling phase using 261.2 N of pull at 0.5 MPa, releasing the part when air is cut.
Packaging Flap Folder
Draws back a carton folding arm on a packaging line; the spring-extended fail-safe clears the path for the next box during an air loss event.
Textile Tension Release
Pulls a fabric tensioning guide out of the web path, relying on the 50 mm stroke to slacken the material for roll changes without powered extension.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL32X50U with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL32X50U
To replace the MTAL32X50U, install the MTBL32X50U. Confirm the 32 mm bore, 50 mm stroke, G1/8 port, PT thread, and flat U back cover. Because this SKU has no -S magnet, it cannot take a sensor; if you need position detection, step up to an MTBL32X50US and use CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. Remember the 0.2 MPa minimum operating pressure and that the fail-safe home is extended.
For sizing flexibility, stepping down to a 25 mm bore yields 137.2 N of pull at 0.5 MPa, while stepping up to a 40 mm bore provides 439.4 N at 0.5 MPa. The fixed rubber bumper absorbs end-of-stroke impact, but it is not a lock. Use an external holding device if you need to secure a load mid-stroke.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL32X50U (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL32X50U instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL32X50U FAQ
Yes, the MTAL32X50U is discontinued. The direct replacement is the MTBL32X50U, which matches the 32 mm bore, 50 mm stroke, U back cover, and G1/8 port. The MTBL upgrades the body to a riveted rolling-packed design, and if you need a magnet, you must use CMSG/DMSG/EMSG sensors.
The usable pull force is 261.2 N at 0.5 MPa and 399.4 N at 0.7 MPa, with a minimum operating pressure of 0.2 MPa. It is a single-acting pull cylinder, meaning air retracts the rod and an internal spring extends it. On air loss, the fail-safe home position is fully extended.
