This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80CA 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 MSAL Front Single Acting Compact Cylinder MSAL20X80CA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80CA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 80mm stroke, G1/8 ports and a fixed rubber bumper. Air drives the push (work) stroke and the spring returns the rod — it rests retracted on air loss. This model is discontinued; the drop-in replacement is the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80CA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80CA
The AirTAC MSAL20X80CA is a discontinued 20mm bore, 80mm stroke mini cylinder. As a single-acting push type, compressed air extends the rod while an internal spring retracts it, providing a fail-safe retracted home on air loss. It yields a usable push force of 106.8 N at 0.5 MPa. The exact drop-in replacement is the MSBL20X80CA, matching the bore, stroke, G1/8 port, and CA clevis mount.
This SKU lacks the -S magnet and cannot accept a position sensor, whereas upgrading to the MSBL allows modern CMSG switches. The original MSAL uses threaded covers, while the MSBL features a riveted rolling-packed body. End-of-stroke damping relies on a fixed rubber bumper, not an adjustable cushion. Apply no external load on the spring return stroke to avoid damaging the internal mechanism.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80CA Technical Specifications

| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80CA |
| Bore size | Ø20 mm |
| Stroke | 80 mm |
| Acting type | Single acting, push (spring return) |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| 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 150 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80CA carries the same single-acting ratings.
Usable Push Force (Ø20mm)
| Pressure | Push force (net of spring) |
|---|---|
| 0.5 MPa | 106.8 N |
| 0.7 MPa | 169.6 N |
Usable single-acting force after the return spring — lower than a same-bore double-acting cylinder. Size with a margin.

Where the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80CA Is Used
PCB Ejector Pins
Pushes delicate printed circuit boards out of a routing fixture using 106.8 N at 0.5 MPa, relying on the spring to retract safely when air is removed.
Light-Part Stamping
Applies a brief 169.6 N stamping force to thin sheet metal tags, with the fixed rubber bumper absorbing the hard stop at the end of the 80mm stroke.
Diverter Gate Actuator
Swings a small pivot gate on the CA clevis pin to sort plastic caps on a conveyor line, returning to a fail-safe home position during an air pressure drop.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80CA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80CA
To replace the MSAL20X80CA with the MSBL20X80CA, confirm the 20mm bore, 80mm stroke, PT G1/8 port, and CA pivot/clevis back cover. Remember the 0.2 MPa minimum operating pressure needed to overcome the return spring. If sizing down, the neighbouring 20mm bore is the smallest available; if you need more force, stepping up to the 32mm bore provides 317.7 N at 0.5 MPa. For an 80mm stroke on this compact 8mm rod, minimize side-load to prevent rod bending.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80CA (same bore/stroke/force)
- ✓ Same push direction and retracted 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80CA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80CA FAQ
Yes, the MSAL20X80CA is discontinued. The exact drop-in replacement is the MSBL20X80CA, which matches the 20mm bore, 80mm stroke, CA clevis, and force class. You only need to update the sensor family if used, as the MSBL uses CMSG switches instead of the older CS1-M.
The usable push force is 12.6 N at 0.2 MPa, 75.4 N at 0.4 MPa, 106.8 N at 0.5 MPa, and 169.6 N at 0.7 MPa. The maximum push force is 169.6 N (17.3 kgf). The operating pressure range is 0.2-1.0 MPa, with a 0.2 MPa minimum required to overcome the return spring.
