This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X45CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X45CA 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 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 drop-in 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 exact drop-in 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 |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X45CA |
| 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 exact drop-in 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.
