This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X40CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X40CA 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 MSAL20X40CA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X40CA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 40mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X40CA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X40CA
The AirTAC MSAL20X40CA is a discontinued single-acting push, spring-return mini cylinder. Air extends the 8 mm rod for the 40 mm work stroke, while an internal spring retracts it to a fail-safe home when air is removed. The 20 mm bore yields a usable push force of 106.8 N at 0.5 MPa (169.6 N at 0.7 MPa). The exact drop-in replacement is the MSBL20X40CA, matching the bore, stroke, G1/8 port, and CA mounting.
This SKU has no -S magnet and cannot take a position sensor. The MSAL uses older CS1-M/DS1-M switches and threaded covers, whereas the MSBL upgrade uses CMSG/DMSG/EMSG sensors and a riveted rolling-packed body. The CA back cover is a pivot clevis that swings on a pin, ideal for arcing loads. End-of-stroke deceleration uses a fixed rubber bumper, not an adjustable cushion.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X40CA Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X40CA |

| Bore size | Ø20 mm |
| Stroke | 40 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X40CA 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 MSAL20X40CA Is Used
PCB Ejector Pins
Pushes finished circuit boards out of test fixtures with 106.8 N at 0.5 MPa, relying on the spring return to retract the pin safely when air drops.
Light Package Stamp
Presses paperboard carton flaps flat during sealing, using the CA pivot clevis to absorb arcing motion while the fixed rubber bumper absorbs the end impact.
Conveyor Diverter Gate
Extends a lightweight guide flap to route plastic bottles on a packaging line, returning to a fail-safe home position if the 0.2 MPa air supply is lost.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X40CA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X40CA
To replace the MSAL20X40CA, install the MSBL20X40CA and confirm the 20 mm bore, 40 mm stroke, PT G1/8 port, M8x1.25 rod-end thread, and CA pivot clevis. Because this SKU lacks the -S magnet, it cannot accept a sensor; the MSBL upgrade moves to the CMSG/DMSG/EMSG family. Operating pressure must be at least 0.2 MPa to beat the return spring, and you must apply no external load on the spring return stroke.
If sizing force, step down to the 12 mm bore (not listed, confirm from datasheet) or step up to the 25 mm bore, which provides 176.4 N at 0.5 MPa. For a 40 mm stroke on these small bores, watch for side loads that could bend the 8 mm rod.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X40CA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X40CA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X40CA FAQ
Yes, the MSAL20X40CA is discontinued. The exact drop-in replacement is the MSBL20X40CA, which matches the 20 mm bore, 40 mm stroke, G1/8 port, and CA pivot clevis. You only need to update your sensor choice to the CMSG/DMSG/EMSG family if upgrading from the older CS1-M/DS1-M switches.
The usable push force is 12.6 N at 0.2 MPa, 44.0 N at 0.3 MPa, 75.4 N at 0.4 MPa, 106.8 N at 0.5 MPa, 138.2 N at 0.6 MPa, and 169.6 N at 0.7 MPa. The maximum force is 169.6 N. It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring.
