This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20SCA 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 MTAL20X20SCA
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X20SCA is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø20mm 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 drop-in replacement is the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20SCA.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X20SCA
The AirTAC MTAL20X20SCA is a discontinued single-acting pull cylinder with a 20mm bore and 20mm 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 direct drop-in replacement is the MTBL20X20SCA, retaining the same G1/8 port, M8 rod, and CA clevis. This MTAL features a magnet for CS1-M/DS1-M switches and threaded covers, whereas the MTBL upgrades to CMSG/DMSG/EMSG sensors and a riveted rolling-packed body. It uses a fixed rubber bumper for end-of-stroke damping.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X20SCA Technical Specifications

|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20SCA |
| Bore size | Ø20 mm |
| Stroke | 20 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20SCA 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 MTAL20X20SCA Is Used
Electronic Connector Latching
Retracts a latch pin on an automated PCB test fixture using its 81.7 N pull at 0.5 MPa, relying on the spring-extend fail-safe to release the board safely on air loss.
Light Tensioning Station
Draws back a small wire tensioning arm in a cable winding machine, where the short 20mm stroke and fixed rubber bumper absorb the end-of-travel shock.
Component Ejector Reset
Pulls a small pneumatic ejector gate closed in a semiconductor pick-and-place handler, using the CS1-M/DS1-M magnet to confirm the retracted position.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X20SCA with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20SCA
To replace this MTAL20X20SCA, specify the MTBL20X20SCA to match the 20mm bore, 20mm stroke, CA pivot cover, and -S magnet. Remember the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. Operating pressure must be at least 0.2 MPa. Apply no external load on the spring extend stroke.
For sizing flexibility, stepping down is not an option as 20mm is the smallest bore. Stepping up to the 32mm bore provides a higher 261.2 N pull at 0.5 MPa if your application requires more force. The CA back cover swings on a pin for arcing loads.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20SCA (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20SCA instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X20SCA FAQ
Yes, the MTAL20X20SCA is discontinued. The exact drop-in replacement is the MTBL20X20SCA, which matches the 20mm bore, 20mm stroke, G1/8 port, and CA mounting. You will only need to update your sensors from the MTAL's CS1-M/DS1-M switches to the MTBL's CMSG/DMSG/EMSG family.
It is a single-acting pull cylinder where air retracts the rod and the spring extends it. The fail-safe home is extended. The usable 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. It requires a minimum operating pressure of 0.2 MPa and uses a fixed rubber bumper.
