This model is discontinued
AirTAC has phased out the MTAL series. You can still order this code here: we ship the direct replacement MTBL32X20SU, 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 MTAL32X20SU
The AirTAC MTAL Rear Single Acting Mini Cylinder MTAL32X20SU is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø32mm bore and 20mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL32X20SU.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL32X20SU
The AirTAC MTAL32X20SU is a discontinued single-acting pull-type mini cylinder with a 32mm bore and 20mm stroke. Air retracts the rod while an internal spring extends it, yielding a fail-safe extended home position. It delivers 261.2N usable pull force at 0.5 MPa. The direct replacement is the MTBL32X20SU, matching the bore, stroke, port, and U cover.
This SKU includes the -S magnet for CS1-M or DS1-M switches; the MTBL replacement upgrades this to CMSG, DMSG, or EMSG sensors. The MTAL uses threaded covers, whereas the newer MTBL features a riveted rolling-packed body. Both retain a fixed rubber bumper and require a minimum 0.2 MPa operating pressure.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL32X20SU Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL32X20SU |

| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL32X20SU |
| Bore size | Ø32 mm |
| Stroke | 20 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL32X20SU 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 MTAL32X20SU Is Used
CNC Lathe Chuck Unlatch
Retracts a collet pull-rod on a CNC lathe with 261.2N at 0.5 MPa. The spring-extended fail-safe ensures the chuck releases safely on air loss.
PCB Test Fixture Drawback
Pulls a moving probe plate away from assembled PCBs. The 20mm stroke provides precise clearance, and the U flat-end cover mounts rigidly to the test frame.
Injection Mold Ejector Reset
Retracts a secondary ejector pin on a 32mm bore mold base. Air retracts the pin during ejection, while the internal spring pushes it back out during mold close.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL32X20SU with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL32X20SU
To replace the MTAL32X20SU, select the MTBL32X20SU to retain the 32mm bore, 20mm stroke, G1/8 port, PT thread, U flat-end back cover, and magnet. Confirm your 3/2 valve supplies at least 0.2 MPa to overcome the return spring. Remember that the fail-safe home is extended, and apply no external load on the spring extend stroke.
For sizing, stepping down to the 25mm bore drops the 0.5 MPa pull force to 137.2N. Stepping up to the 40mm bore increases it to 439.4N at 0.5 MPa. The 20mm stroke is short and highly resistant to rod bending, making it ideal for compact pulls.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL32X20SU (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL32X20SU instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL32X20SU FAQ
Yes, the MTAL32X20SU is discontinued. The direct replacement is the MTBL32X20SU, which matches the 32mm bore, 20mm stroke, G1/8 port, U cover, and magnet. The MTBL upgrades the threaded covers to a riveted rolling-packed body and changes the sensor family from CS1-M/DS1-M to CMSG/DMSG/EMSG.
It is a single-acting pull cylinder with a fixed rubber bumper. Usable pull force is 261.2N at 0.5 MPa and 399.4N at 0.7 MPa. Operating pressure is 0.2-1.0 MPa (minimum 0.2 MPa), speed is 50-800 mm/s, and the fail-safe home is extended.
