This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20SCM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20SCM 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).

The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X20SCM is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø40mm bore and 20mm stroke, G1/4 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20SCM.
The AirTAC MTAL40X20SCM is a discontinued single-acting pull cylinder with a 40 mm bore and 20 mm 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 439.4 N at 0.5 MPa and 650.4 N at 0.7 MPa.
The exact drop-in replacement is the MTBL40X20SCM, matching the G1/4 port, M12x1.25 rod thread, CM round-end back cover, and magnet. This original MTAL features threaded covers and uses older CS1-M / DS1-M switches, whereas the MTBL upgrade uses a riveted rolling-packed body and CMSG / DMSG / EMSG sensors. End-of-stroke damping relies on a fixed rubber bumper, not an adjustable cushion.

| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20SCM carries the same single-acting ratings.
| Pressure | Pull force (net of spring) |
|---|---|
| 0.5 MPa | 439.4 N |
| 0.7 MPa | 650.4 N |
Usable single-acting force after the return spring — lower than a same-bore double-acting cylinder. Size with a margin.

|---|---|
| 40 | Bore size in mm (20/25/32/40). |
| ×20 | Stroke length in mm. |
| S | Optional magnet for a CS1-M / DS1-M sensor (MTBL uses CMSG/DMSG/EMSG). |
| CA / U / CM | Back cover: CA pivot, U flat-end or CM round-end. |
Replacement: MTAL → MTBL. Related: MSAL/MSBL (single-acting push), MAL/MBL (double acting).
Pulls a light safety light-curtain guard out of the way on a press brake. The 439.4 N pull at 0.5 MPa overcomes mechanism friction, and the spring-extend fail-safe parks the guard open on air loss.
Draws back a cardboard flap tensioning arm on a carton erector. The 40 mm bore provides 650.4 N at 0.7 MPa to hold the flap, while the single-acting spring extend releases tension safely when air is removed.
Retracts a mechanical ejector pin lock on an injection molding press. Air retracts the 16 mm rod to clear the mold, and the fail-safe extended position ensures the lock engages if compressed air drops.
To replace this MTAL40X20SCM, use the MTBL40X20SCM drop-in. Verify your 40 mm bore, 20 mm stroke, G1/4 port, PT thread, CM round-end cover, and mounting. The -S magnet switches from CS1-M / DS1-M to CMSG / DMSG / EMSG. Maintain a 0.2 MPa minimum pressure, and apply no external load on the spring extend stroke for safety.
If sizing down, the 32 mm bore offers 261.2 N at 0.5 MPa. If stepping up, note this 40 mm is the largest standard MAL series bore, delivering 439.4 N at 0.5 MPa. The fail-safe home is extended, so use an external lock if you must hold a mid-stroke load.
Upgrade checklist
Yes, the MTAL40X20SCM is discontinued. The exact drop-in replacement is the MTBL40X20SCM, which matches the 40 mm bore, 20 mm stroke, G1/4 port, and CM cover. The MTBL upgrades the body to a riveted rolling-packed design and changes the magnet switches from CS1-M / DS1-M to CMSG / DMSG / EMSG.
It is a single-acting pull cylinder, so air retracts the rod and a spring extends it. The fail-safe home is extended. The usable pull force is 439.4 N at 0.5 MPa and 650.4 N at 0.7 MPa, requiring a 0.2 MPa minimum pressure. It uses a fixed rubber bumper, not an adjustable cushion.
