This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30CM 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 MSAL20X30CM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30CM is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 30mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30CM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30CM
The AirTAC MSAL20X30CM is a discontinued single-acting push mini cylinder with a 20 mm bore and 30 mm stroke. Air extends the rod for the work stroke, while an internal spring retracts it to a fail-safe home when air is removed. It yields 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 MSBL20X30CM, matching the bore, stroke, G1/8 port, and CM round-end cover.
This SKU lacks the -S magnet, so it cannot take a position sensor. The MSAL uses older threaded covers, while the MSBL upgrade features a riveted rolling-packed body. It uses a fixed rubber bumper for end-of-stroke damping, not an adjustable cushion. Minimum working pressure is 0.2 MPa to overcome the return spring, and you must apply no external load on the return stroke.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30CM Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30CM |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30CM |
| Bore size | Ø20 mm |
| Stroke | 30 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30CM 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 MSAL20X30CM Is Used
PCB Ejector Pins
Pushes thin printed circuit boards out of an assembly fixture with 106.8 N at 0.5 MPa, relying on the spring return to retract the pin safely when air is cut.
Chip Sorter Diverters
Actuates a small gate to route microchips on a test line, where the fail-safe retracted home ensures the lane stays open during an air loss shutdown.
Light-Part Stamper
Applies a 169.6 N peak push at 0.7 MPa to emboss date codes on plastic housings, with the fixed rubber bumper absorbing the impact at the end of the 30 mm stroke.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30CM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30CM
To replace this MSAL20X30CM with the MSBL20X30CM, confirm the 20 mm bore, 30 mm stroke, G1/8 port, PT thread, and CM round-end back cover. Because this SKU has no -S magnet, it cannot accept a sensor; if you need position detection, step up to an -S variant using CMSG/DMSG/EMSG switches. Minimum operating pressure is 0.2 MPa. If you need more force, the next size up is the 25 mm bore delivering 176.4 N at 0.5 MPa; if you need less, the 20 mm is the smallest available in this series. For a 30 mm stroke on this small bore, rod bending is negligible, but always avoid side loads.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30CM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30CM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30CM FAQ
Yes, the MSAL20X30CM is discontinued. The exact drop-in replacement is the MSBL20X30CM, which matches the 20 mm bore, 30 mm stroke, 106.8 N push force at 0.5 MPa, 169.6 N at 0.7 MPa (17.3 kgf max), G1/8 port, and CM cover.
No. Because this specific SKU lacks the -S magnet designation, it cannot accept a position sensor. The older MSAL -S variants used CS1-M or DS1-M switches, while the current MSBL replacement uses CMSG, DMSG, or EMSG sensors.
