This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X10U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X10U 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 MSAL20X10U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X10U is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 10mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X10U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X10U
The AirTAC MSAL20X10U is a discontinued single-acting push cylinder with a 10 mm stroke and 20 mm bore. Air extends the rod to do its work, while an internal spring retracts it to a fail-safe home when air is removed. This 20 mm bore delivers a usable push force of 106.8 N at 0.5 MPa. The exact drop-in replacement is the MSBL20X10U, matching the bore, stroke, and G1/8 port.
This U-coded SKU features a flat-end back cover for rigid mounting. It has no magnet, so it cannot take a position sensor. As an upgrade fact, the MSAL uses threaded covers and older switches, whereas the MSBL replacement features a riveted rolling-packed body. End-of-stroke damping is handled by a fixed rubber bumper, as there is no adjustable cushion. Minimum working pressure is 0.2 MPa to overcome the return spring.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X10U Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X10U |

| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X10U |
| Bore size | Ø20 mm |
| Stroke | 10 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X10U 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 MSAL20X10U Is Used
PCB Ejector Pin
Pushes a small 10 mm stroke to eject populated circuit boards from a test fixture, using 106.8 N at 0.5 MPa to overcome socket friction before the spring retracts clear.
Connector Latch Release
Briefly extends to unseat a delicate fiber-optic connector latch, relying on the fail-safe spring return to guarantee the pin clears the housing when air is cut.
Indexer Gate Deflector
Acts as a momentary diverter on a small-parts conveyor, popping up 10 mm to deflect plastic caps into a reject chute and springing back to let standard parts pass.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X10U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X10U
To replace this MSAL20X10U with the MSBL20X10U, confirm the 20 mm bore, 10 mm stroke, G1/8 PT port, and flat-end U back cover. Because this SKU lacks the -S magnet, it cannot accept a sensor. The MSBL upgrade changes the switch family to CMSG/DMSG/EMSG if you ever need position detection. Minimum air pressure must be 0.2 MPa. Apply no external load on the spring return stroke.
If sizing your force needs, this 20 mm bore pushes 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa. Stepping up to the 25 mm bore yields 176.4 N at 0.5 MPa. As the smallest available bore, there is no smaller size to step down to. Even at this 10 mm stroke, minimize side loads to prevent rod bending.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X10U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X10U instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X10U FAQ
Yes, the MSAL20X10U is discontinued. The exact drop-in replacement is the AirTAC MSBL20X10U. It matches the 20 mm bore, 10 mm stroke, single-acting push function, and G1/8 port. The MSBL upgrades the body to a riveted rolling-packed design but retains the same force class.
The usable push force is 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa. The minimum working pressure is 0.2 MPa because the air must overcome the internal return spring. The maximum push force is 169.6 N at 0.7 MPa.
