This model is discontinued
AirTAC has phased out the MTAL series. You can still order this code here: we ship the direct replacement MTBL20X75SCA, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 MTAL20X75SCA
The AirTAC MTAL Rear Single Acting Mini Cylinder MTAL20X75SCA is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø20mm bore and 75mm 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 direct replacement is the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X75SCA.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X75SCA
The AirTAC MTAL20X75SCA is a discontinued single-acting pull-type mini cylinder. Air retracts the rod while an internal spring extends it, meaning the fail-safe home position is extended. It delivers a usable pull force of 81.7 N at 0.5 MPa. The direct replacement is the MTBL20X75SCA, matching the 20mm bore, 75mm stroke, G1/8 port, and CA mounting.
This SKU includes the -S magnet for position sensing. On the MTAL, this uses the older CS1-M or DS1-M switches, whereas the MTBL replacement takes CMSG, DMSG, or EMSG sensors. The MTAL features threaded covers and a fixed rubber bumper, while the current MTBL uses a riveted rolling-packed body. Apply no external load on the spring extend stroke to avoid damaging the internal return mechanism.

|---|---|
| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X75SCA 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 MTAL20X75SCA Is Used
Electronic Connector Unlatching
Pulls a spring-loaded latch back to release PCB connector arrays. The 81.7 N pull at 0.5 MPa reliably clears the retention hook, while the spring-extended fail-safe ensures the latch stays locked during an air loss.
Textile Yarn Tensioning
Draws back a tensioning idler arm in a knitting machine. The single-acting design uses one 3/2 valve to retract the arm, with the internal spring smoothly extending it to maintain consistent yarn tension when air is removed.
Packaging Flap Folding
Retracts a carton folder blade on a packaging line. The CA pivot clevis accommodates the arcing motion of the folder arm, preventing binding while the cylinder pulls the flap down against the fixed rubber bumper.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X75SCA with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X75SCA
To replace this MTAL20X75SCA, install the MTBL20X75SCA. Confirm the 20mm bore, 75mm stroke, M8x1.25 rod thread, PT port thread, and the CA pivot clevis. Swap your CS1-M or DS1-M sensors for CMSG, DMSG, or EMSG models. Maintain a minimum 0.2 MPa operating pressure and remember the fail-safe home is extended.
For sizing, this 20mm bore provides 81.7 N pull at 0.5 MPa and 134.4 N at 0.7 MPa. If you need less force, step down to the 32mm bore is not applicable, but stepping up to the 25mm bore yields 137.2 N at 0.5 MPa. At 75mm stroke, ensure your mounting handles side-load and rod-bending forces, as the fixed rubber bumper cannot absorb severe lateral impacts.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X75SCA (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X75SCA instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X75SCA FAQ
Yes, the MTAL20X75SCA is discontinued. The direct replacement is the MTBL20X75SCA. It matches the 20mm bore, 75mm stroke, G1/8 port, and CA mounting. You must upgrade your CS1-M or DS1-M sensors to the CMSG, DMSG, or EMSG family for the new cylinder.
It is a single-acting pull cylinder with a spring-extended fail-safe home. On air loss, the spring pushes the rod out. The usable pull force net of the spring is 81.7 N at 0.5 MPa and 134.4 N at 0.7 MPa, requiring a minimum 0.2 MPa operating pressure. It cannot hold a load mid-stroke without an external locking device.
