This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25CM 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 MTAL20X25CM
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X25CM is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø20mm bore and 25mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25CM.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X25CM
The AirTAC MTAL20X25CM is a discontinued single-acting pull-type mini cylinder with a 20mm bore and 25mm stroke. Air retracts the rod while an internal spring extends it, yielding a fail-safe extended home position. This bare 20mm bore delivers a usable pull force of 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa. The direct drop-in replacement is the MTBL20X25CM, matching the bore, stroke, G1/8 port, and CM cover.
This MTAL20X25CM variant uses a CM round-end back cover and a PT tapered port thread. It lacks the -S magnet option, so it cannot accept a position sensor. Two upgrade details define the MTBL transition: the older MTAL uses threaded covers and CS1-M/DS1-M sensors, whereas the MTBL features a riveted rolling-packed body and CMSG/DMSG/EMSG switches. Remember to apply no external load on the spring extend stroke.

| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25CM 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 MTAL20X25CM Is Used
Textile Loom Tension Arm
Retracts a thread tensioning guide on a weaving loom. The 81.7 N pull at 0.5 MPa handles the lever resistance, while the spring-extended fail-safe releases tension instantly on air loss to prevent yarn snapping.
PCB Conveyor Snubber
Pulls a board-stop pin on an electronics assembly line. The 20mm bore fits tight conveyor gaps, and the 25mm stroke provides just enough retraction to clear the PCB pathway for part transfer.
Packaging Flap Break
Draws back a mechanical brake on a carton erector. The spring-extended home keeps the brake engaged during an air pressure drop, holding the cardboard flap securely without powered mid-stroke locking.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X25CM with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25CM
To replace the MTAL20X25CM, order the MTBL20X25CM. Confirm the 20mm bore, 25mm stroke, G1/8 port, M8x1.25 rod thread, CM back cover, and PT thread. Because this SKU has no -S magnet, it cannot take a sensor; if you need detection, step up to an MTBL20X25SCM and use CMSG/DMSG/EMSG switches. Maintain a 0.2 MPa minimum pressure and apply no external load on the spring extend stroke. The fail-safe home is extended.
For sizing both ways, step down is not available as 20mm is the smallest bore. To step up, the 25mm bore offers 137.2 N at 0.5 MPa. The 20mm bore operates at 50-800 mm/s and uses a fixed rubber bumper, not an adjustable lock. At a 25mm stroke, rod-bending side loads are minimal, but keep the guide aligned.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25CM (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X25CM instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X25CM FAQ
Yes, the MTAL20X25CM is discontinued. The exact drop-in replacement is the MTBL20X25CM, matching the 20mm bore, 25mm stroke, G1/8 port, and CM cover. The MTBL upgrades the body to a riveted rolling-packed design and uses CMSG/DMSG/EMSG sensors if you add a magnet.
The 20mm bore provides a usable pull force of 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa. It is single-acting pull, so air retracts the rod against a small internal spring. The fail-safe home is extended; on air loss, the spring pushes the rod back out. It requires a 0.2 MPa minimum pressure.
