This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X20SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X20SU 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 MTAL25X20SU
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X20SU is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø25mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X20SU.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X20SU
The AirTAC MTAL25X20SU is a discontinued single-acting pull-type mini cylinder. Air retracts the rod while an internal spring extends it, providing a fail-safe extended home position. It delivers a usable pull force of 137.2 N at 0.5 MPa and requires a minimum operating pressure of 0.2 MPa.
The exact drop-in replacement is the MTBL25X20SU. It matches the 25 mm bore, 20 mm stroke, G1/8 port, and U back cover. The MTAL uses threaded covers and a CS1-M or DS1-M magnet switch, while the MTBL upgrades to a riveted rolling-packed body and CMSG, DMSG, or EMSG sensors. Both share a fixed rubber bumper and the same force class.

| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X20SU |
| Bore size | Ø25 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X20SU carries the same single-acting ratings.
Usable Pull Force (Ø25mm)
| Pressure | Pull force (net of spring) |
|---|---|
| 0.5 MPa | 137.2 N |
| 0.7 MPa | 219.6 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 MTAL25X20SU Is Used
Textile Loom Tension Gate
Pulls a yarn tensioning gate closed against thread run. The 137.2 N pull at 0.5 MPa holds the gate, while the spring-extended fail-safe opens the gate on air loss to prevent thread snapping.
CNC Lathe Chuck Lever
Retracts a secondary collet lever on a CNC lathe. The 20 mm stroke moves the lever precisely, and the fail-safe extended position safely disengages the lever when machine air drops.
Conveyor Diverter Arm
Draws back a pneumatic diverter arm on a packaging conveyor. The single-acting pull retracts the arm to route boxes, and the spring extends it to a safe rest when the line halts.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X20SU with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X20SU
To replace the MTAL25X20SU, install the MTBL25X20SU. Confirm the 25 mm bore, 20 mm stroke, M10x1.25 rod-end thread, G1/8 PT port, U flat-end back cover, and the magnet sensor family change from CS1-M/DS1-M to CMSG/DMSG/EMSG. Remember the 0.2 MPa minimum pressure and never apply external load on the spring extend stroke, as the fail-safe home is extended.
For sizing, step down to the 20 mm bore for 81.7 N pull at 0.5 MPa, or step up to the 32 mm bore for 261.2 N pull at 0.5 MPa. This 25 mm bore gives 137.2 N at 0.5 MPa and 219.6 N at 0.7 MPa.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X20SU (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL25X20SU instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL25X20SU FAQ
Yes, the MTAL25X20SU is discontinued. The exact drop-in replacement is the MTBL25X20SU, which matches the 25 mm bore, 20 mm stroke, G1/8 port, and U back cover. You will only need to update your magnet sensors from the older CS1-M/DS1-M switches to the new CMSG/DMSG/EMSG family.
This single-acting pull cylinder provides a usable pull force of 137.2 N at 0.5 MPa and 219.6 N at 0.7 MPa. It operates on 0.2 to 1.0 MPa air pressure, requires a 3/2 valve, and moves at 50-800 mm/s. The maximum standard stroke is 100 mm.
