This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50CA 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 MSAL40X50CA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X50CA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 50mm stroke, G1/4 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50CA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X50CA
The AirTAC MSAL40X50CA is a discontinued single-acting push, spring-return mini cylinder. Air extends the 16mm rod for the work stroke, while an internal spring retracts it to a fail-safe home when air is removed. This 40mm bore delivers 539.9 N of usable push force at 0.5 MPa (791.1 N at 0.7 MPa). The exact drop-in replacement is the MSBL40X50CA, matching the bore, stroke, G1/4 port, and CA clevis.
This SKU features a CA pivot clevis back cover that swings on a pin to absorb arcing loads, and uses a fixed rubber bumper for end-of-stroke damping. It has no -S magnet, meaning it cannot accept a position sensor. During your upgrade to the MSBL, note the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG if you ever add switches, and the construction shifts from these threaded covers to a riveted rolling-packed body.

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50CA carries the same single-acting ratings.
Usable Push Force (Ø40mm)
| Pressure | Push force (net of spring) |
|---|---|
| 0.5 MPa | 539.9 N |
| 0.7 MPa | 791.1 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 MSAL40X50CA Is Used
Stamping Press Ejection
Ejects formed sheet metal brackets from a stamping die. The 539.9 N push force at 0.5 MPa clears heavy parts, and the spring return retracts safely when air is cut.
Pivoting Gate Diversion
Actuates a heavy diverter gate on a packaging conveyor. The CA clevis accommodates the arcing swing of the gate, while the fail-safe spring return closes the gate on air loss.
Plastic Mold Clamping
Holds injection mold halves aligned during a low-pressure press fit. The fixed rubber bumper absorbs the 50mm stroke impact without requiring adjustment.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X50CA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50CA
To replace this MSAL40X50CA with the MSBL40X50CA, confirm the 40mm bore, 50mm stroke, G1/4 port, PT thread, and CA clevis. Because this is the largest standard MAL bore, you cannot step up within the series; if 539.9 N at 0.5 MPa is insufficient, you must move to a larger ISO cylinder. If you need less force, stepping down to the 32mm bore yields 317.7 N at 0.5 MPa. Remember the 0.2 MPa minimum pressure required to overcome the return spring, and never apply an external load on the spring return stroke. At a 50mm stroke on this 40mm bore, side-load and rod-bending risks are low, but ensure the CA clevis pin is aligned to prevent binding.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50CA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50CA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X50CA FAQ
Yes, the MSAL40X50CA is discontinued. The exact drop-in replacement is the MSBL40X50CA, which matches the 40mm bore, 50mm stroke, G1/4 port, and CA clevis. The MSBL upgrades the body to a riveted rolling-packed design from the original threaded covers.
This single-acting push cylinder delivers 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa (roughly 80 kgf max). Because the internal return spring opposes the air stroke, the minimum working pressure is 0.2 MPa. It cannot hold a load mid-stroke; the spring drives it to a retracted rest on air loss.
