This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X125CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X125CA 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 MSAL20X125CA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X125CA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 125mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X125CA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X125CA
The AirTAC MSAL20X125CA is a discontinued single-acting push, spring-return mini cylinder. Air extends the 8 mm rod for a 125 mm stroke, while an internal spring retracts it to a fail-safe home when air is removed. The exact drop-in replacement is the MSBL20X125CA, matching the 20 mm bore, stroke, G1/8 port, and CA pivot cover. This bore delivers a usable push force of 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa.
Because this SKU lacks the -S magnet, it cannot accept a position sensor. The original MSAL uses threaded covers and the older CS1-M / DS1-M switches; the MSBL replacement upgrades to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors. End-of-stroke deceleration relies on a fixed rubber bumper, as single-acting models do not use adjustable cushions.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X125CA Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X125CA |

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X125CA 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 MSAL20X125CA Is Used
PCB Router Gate
Pushes a safety guard down during router operation; the spring return lifts the gate to a fail-safe open position if plant air drops.
Textile Bobbin Ejector
Uses the 106.8 N push force at 0.5 MPa to kick wound bobbins off a winding spindle, relying on the CA pivot to absorb angular misalignment.
Light Stamping Press
Applies a 169.6 N stamping force at 0.7 MPa onto thin foils, with the fixed rubber bumper absorbing the impact at the end of the 125 mm stroke.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X125CA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X125CA
To replace this MSAL20X125CA, install the MSBL20X125CA. Confirm the 20 mm bore, 125 mm stroke, G1/8 PT port, M8x1.25 rod thread, and CA clevis back cover. If you need position sensing, you must move to an -S designated MSBL model, as this no-magnet SKU cannot take a sensor. Remember the 0.2 MPa minimum pressure required to overcome the return spring, and apply no external load on the return stroke.
For sizing, stepping down to the next available size is not possible as 20 mm is the minimum bore. Stepping up to a 32 mm bore increases the 0.5 MPa push force to 317.7 N. At 125 mm of stroke on this small 8 mm rod, verify your mounting alignment carefully to prevent rod bending and side-load wear.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X125CA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X125CA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X125CA FAQ
Yes, the MSAL20X125CA is discontinued. The exact drop-in replacement is the MSBL20X125CA, which matches the 20 mm bore, 125 mm stroke, G1/8 port, and CA pivot cover. The MSBL upgrades the body to a riveted rolling-packed design.
The usable push force is 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa. The maximum equivalent is roughly 17.3 kgf. It requires a minimum operating pressure of 0.2 MPa to overcome the return spring, with a maximum operating pressure of 1.0 MPa.
