This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80SU 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 MSAL20X80SU
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80SU 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80SU.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80SU
The AirTAC MSAL20X80SU is a discontinued single-acting push, spring-return mini cylinder. Air extends the 8 mm rod for the 80 mm stroke, while an internal spring retracts it to a fail-safe home when air is removed. It delivers a usable push force of 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa. The exact drop-in replacement is the MSBL20X80SU, matching the 20 mm bore, 80 mm stroke, G1/8 port, and U flat-end back cover.
This SKU features a -S magnet for position sensing. As an MSAL, it uses the older CS1-M or DS1-M reed switches, whereas the MSBL replacement upgrades to CMSG, DMSG, or EMSG solid-state sensors. The original MSAL body uses threaded covers, while the modern MSBL features a riveted rolling-packed body for better structural integrity. Both generations use a fixed rubber bumper for end-of-stroke damping, meaning there is no adjustable cushioning.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80SU Technical Specifications

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80SU 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 MSAL20X80SU Is Used
PCB Router Gate
Pushes a deflecting gate to route printed circuit boards down a conveyor lane; the 106.8 N force at 0.5 MPa easily handles light board masses.
Foam Tray Press
Extends 80 mm to flatten packing foam trays into cartons; the spring return ensures the press retracts safely on air loss.
Connector Insertion
Pushes low-profile electronic connectors into test sockets with controlled force before the spring retracts the 8 mm rod.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80SU with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80SU
To replace the MSAL20X80SU, specify the MSBL20X80SU to retain the 20 mm bore, 80 mm stroke, M8x1.25 rod thread, G1/8 PT port, U flat-end back cover, and -S magnet. Remember that the MSBL -S magnet requires CMSG, DMSG, or EMSG sensors instead of the older CS1-M or DS1-M switches. Ensure your air supply is filtered to 40 um and maintains at least 0.2 MPa to overcome the return spring. Never apply an external load on the unpowered return stroke.
For sizing flexibility, you can step down or up from this 20 mm bore. Stepping down is not an option as 20 mm is the smallest available bore. Stepping up to the 32 mm bore provides a higher usable push force of 317.7 N at 0.5 MPa if your application requires more clamping strength. Since the 80 mm stroke on this small 20 mm bore creates a long, slender rod, verify your mounting to prevent side-load rod bending.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80SU (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X80SU instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X80SU FAQ
Yes, the MSAL20X80SU is discontinued. The exact drop-in replacement is the MSBL20X80SU. It matches the 20 mm bore, 80 mm stroke, G1/8 port, U flat-end back cover, and single-acting push function. You only need to update your sensors from the older CS1-M or DS1-M switches to the CMSG, DMSG, or EMSG family.
The usable push force, already net of the opposing return spring, is 12.6 N at 0.2 MPa, 106.8 N at 0.5 MPa, and 169.6 N at 0.7 MPa. The minimum operating pressure is 0.2 MPa, which is required to overcome the internal return spring. The maximum pressure is 1.0 MPa.
