This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X45SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X45SCA 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 MSAL20X45SCA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X45SCA 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X45SCA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X45SCA
The AirTAC MSAL20X45SCA is a discontinued single-acting push, spring-return mini cylinder. Air extends the Ø8 mm rod for the 45 mm work stroke, while an internal spring retracts it to a fail-safe home when air is removed. It delivers a usable push force of 106.8 N at 0.5 MPa. The exact drop-in replacement is the MSBL20X45SCA, matching the bore, stroke, G1/8 port, and CA clevis.
This -S variant includes a magnet for position sensing. The legacy MSAL works with older CS1-M / DS1-M reed switches, whereas the MSBL upgrade uses CMSG / DMSG / EMSG sensors. The original MSAL features threaded covers, while the MSBL utilizes a riveted rolling-packed body. End-of-stroke damping relies on a fixed rubber bumper, meaning there is no adjustable cushion. Never apply an external load on the unpowered spring return stroke.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X45SCA Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X45SCA |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X45SCA |
| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X45SCA 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 MSAL20X45SCA Is Used
PCB Ejector Pin
Pushes bare circuit boards out of an SMT testing fixture using 106.8 N at 0.5 MPa, relying on the spring return to retract the pin safely during panel unloading.
Connector Sorting Gate
Diverts plastic connector housings down a conveyor chute; the CA clevis handles the slight arcing motion as the gate flips, with the fail-safe home preventing jams on air loss.
Light Part Stamper
Presses a small date code onto aluminum tags using 169.6 N at 0.7 MPa, where the fixed rubber bumper absorbs the impact at the end of the 45 mm stroke.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X45SCA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X45SCA
To replace this MSAL20X45SCA, specify the MSBL20X45SCA. Confirm the 20 mm bore, 45 mm stroke, G1/8 PT port, M8x1.25 rod thread, CA pivot clevis, and the sensor family change from CS1-M/DS1-M to CMSG/DMSG. Operating pressure must be at least 0.2 MPa to overcome the return spring. If you need less force, there is no smaller standard bore in this series. If you need more force, step up to the 25 mm bore, which provides 176.4 N of push at 0.5 MPa. Because this 45 mm stroke is relatively short, side-load risks are minimal, but always ensure the CA clevis swings freely to absorb rod misalignment.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X45SCA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X45SCA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X45SCA FAQ
Yes, the MSAL20X45SCA is discontinued. The exact drop-in replacement is the MSBL20X45SCA. It matches the 20 mm bore, 45 mm stroke, G1/8 port, and CA clevis. You only need to update your sensors: the old MSAL -S magnet uses CS1-M / DS1-M switches, while the MSBL uses CMSG / DMSG / EMSG switches.
This single-acting push cylinder provides a usable force of 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa (equivalent to roughly 17.3 kgf). Because an internal spring opposes the air stroke, the minimum operating pressure is 0.2 MPa. The maximum standard pressure is 1.0 MPa.
