This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20CM 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 MTAL20X20CM
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X20CM 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20CM.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X20CM
The AirTAC MTAL20X20CM is a discontinued 20mm bore, 20mm stroke single-acting pull cylinder with a spring-extend fail-safe. Air retracts the rod for the work stroke, while an internal spring extends it when air is released. It 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 MTBL20X20CM, matching the bore, stroke, CM round-end back cover, and G1/8 port.
This MTAL20X20CM features a CM round-end back cover and PT tapered port thread. Because this SKU lacks the -S magnet code, it cannot accept a position sensor. The original MTAL uses threaded covers and older CS1-M/DS1-M switches; the MTBL upgrade features a riveted rolling-packed body and uses CMSG/DMSG/EMSG sensors. A fixed rubber bumper absorbs end-of-stroke impact. 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20CM 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 MTAL20X20CM Is Used
Electronic PCB Ejector
Pulls a spring-loaded ejector pin back inside a test fixture to release populated circuit boards, using 81.7 N at 0.5 MPa. The spring-extended fail-safe ensures the pin stays out and clears the board on air loss.
Textile Yarn Tension Gate
Retracts a tensioning guide pulley out of the thread path during machine stoppages. The 20mm stroke provides fast withdrawal, and the spring-extend home safely restores tension when air is removed.
Small Parts Sorter Diverter
Draws a pneumatic flap back to let plastic fasteners pass to the reject bin. The 134.4 N pull at 0.7 MPa handles the lightweight flap, while the extended fail-safe blocks the reject path during outages.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X20CM with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20CM
To replace an MTAL20X20CM, use the drop-in MTBL20X20CM. Confirm the 20mm bore, 20mm stroke, G1/8 port, M8x1.25 rod thread, CM back cover, and the lack of a magnet (this no-S SKU cannot take a sensor). Remember the 0.2 MPa minimum operating pressure and that the fail-safe home is EXTENDED. Never apply external load to the spring extend stroke.
If sizing a new cylinder, step up to the 25mm bore for 137.2 N pull at 0.5 MPa. As the smallest available bore (20mm), there is no smaller size to step down to; if 81.7 N at 0.5 MPa is too high, adjust your pressure down to the 0.2 MPa minimum.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20CM (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X20CM instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X20CM FAQ
Yes, the MTAL20X20CM is discontinued. The exact drop-in replacement is the MTBL20X20CM, matching the 20mm bore, 20mm stroke, CM back cover, and G1/8 port. The MTBL upgrades the threaded covers to a riveted rolling-packed body.
The usable pull force (net of spring) is 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa, requiring a 0.2 MPa minimum pressure. It is a single-acting pull cylinder: air retracts the rod, and the fail-safe home is EXTENDED, meaning the spring pushes the rod back out on air loss.
