This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X50CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X50CA 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 MSAL20X50CA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X50CA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 50mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X50CA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X50CA
The AirTAC MSAL20X50CA is a discontinued single-acting push, spring-return mini cylinder. Air extends the 8 mm rod for the 50 mm stroke, while an internal spring retracts it. It provides 106.8 N of usable push force at 0.5 MPa and 169.6 N at 0.7 MPa. The drop-in replacement is the MSBL20X50CA, matching the 20 mm bore, stroke, G1/8 port, and CA clevis.
This CA back cover is a pivot eye that swings on a pin to absorb arcing loads. The MSAL uses threaded covers and older CS1-M/DS1-M sensors if a magnet is present, whereas the MSBL upgrade features a riveted rolling-packed body and CMSG/DMSG/EMSG switches. This specific SKU lacks the -S magnet, so it cannot accept a position sensor. End-of-stroke deceleration uses a fixed rubber bumper, not an adjustable cushion.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X50CA Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X50CA |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X50CA |
| Bore size | Ø20 mm |
| Stroke | 50 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X50CA 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 MSAL20X50CA Is Used
PCB router clamp
Holds a printed circuit board flat against a router bed with 106.8 N at 0.5 MPa; the spring retracts the pin clear of the spindle when air is removed.
Chip ejector pin
Pushes finished microchips out of a test socket; the CA pivot eye accommodates slight alignment variance during the ejection arc.
Pneumatic diverter gate
Snaps a small chute flap to route tiny plastic parts; the spring provides a fail-safe retracted home so the line defaults to the main path on air loss.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X50CA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X50CA
To replace the MSAL20X50CA, specify the MSBL20X50CA. Confirm the 20 mm bore, 50 mm stroke, PT G1/8 port, M8x1.25 rod-end thread, CA pivot cover, and that no magnet is needed (this SKU cannot take a sensor). Operating pressure must stay 0.2-1.0 MPa; below 0.2 MPa the air cannot beat the return spring. Apply no external load on the return stroke.
For sizing, if 106.8 N at 0.5 MPa is insufficient, step up to the 25 mm bore giving 176.4 N. If you need less force, there is no smaller standard MAL bore, so 20 mm is the floor. At this 50 mm stroke on a 20 mm bore, watch for side-load and rod-bending if the load is not guided.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X50CA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X50CA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X50CA FAQ
Yes, the MSAL20X50CA is discontinued. The exact drop-in replacement is the MSBL20X50CA, matching the 20 mm bore, 50 mm stroke, CA pivot cover, G1/8 port, and force class. You only swap the cylinder body; the MSBL upgrades the threaded covers to a riveted body.
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 (max). Minimum working pressure is 0.2 MPa because air must overcome the internal return spring to extend the rod.
