This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL20X45CA, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 MSAL20X45CA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X45CA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 45mm 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 direct replacement is the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X45CA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X45CA
The AirTAC MSAL20X45CA is a discontinued single-acting push, spring-return mini cylinder. Air extends the 8mm rod for the 45mm stroke; an internal spring retracts it to a fail-safe home. This 20mm bore delivers 106.8 N of usable push at 0.5 MPa. The direct replacement is the MSBL20X45CA, matching the bore, stroke, G1/8 port, and CA pivot cover.
This CA back cover swings on a pin for arcing loads. This SKU lacks the -S magnet, so it cannot take a position sensor. The MSAL uses older threaded covers and CS1-M switches; the MSBL upgrade features a riveted rolling-packed body and CMSG sensors. End-of-stroke damping uses a fixed rubber bumper, not an adjustable cushion.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X45CA Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X45CA |

| Bore size | Ø20 mm |
| Stroke | 45 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X45CA 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 MSAL20X45CA Is Used
PCB Router Clamping
Secures small PCB panels during router depaneling using 106.8 N of push force at 0.5 MPa, releasing the board safely to a spring-return home on air loss.
IC Tube Ejection
Pushes singulated IC tubes out of a testing nest with 169.6 N at 0.7 MPa, relying on the CA pivot to absorb slight angular misalignment.
Bottle Diverter Gate
Actuates a lightweight plastic diverter arm on a packaging line, where the fail-safe spring return clears the lane when the 3/2 valve is de-energized.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X45CA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X45CA
To replace this MSAL20X45CA with the MSBL20X45CA, confirm the 20mm bore, 45mm stroke, PT G1/8 port, M8x1.25 rod thread, and CA pivot cover. Because this SKU lacks the -S magnet, it cannot accept a position sensor. The MSBL upgrade switches you to the CMSG / DMSG / EMSG sensor family. Maintain a 0.2 MPa minimum air pressure to overcome the return spring, and apply NO external load on the spring return stroke.
For sizing, the 20mm bore yields 106.8 N at 0.5 MPa. Stepping down is not an option as this is the smallest standard bore. Stepping up to the 25mm bore gives 176.4 N at 0.5 MPa if you need more clamping force. At 45mm stroke on this compact body, prevent side-load and rod-bending by guiding the load precisely.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X45CA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X45CA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X45CA FAQ
Yes, the MSAL20X45CA is discontinued. The direct replacement is the MSBL20X45CA, which matches the 20mm bore, 45mm stroke, CA pivot cover, and G1/8 port.
The usable push force is 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa (max 17.3 kgf). It requires a minimum operating pressure of 0.2 MPa to overcome the return spring.
