This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X50U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X50U 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 MSAL32X50U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL32X50U is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø32mm bore and 50mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X50U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL32X50U
The AirTAC MSAL32X50U is a discontinued 32mm bore, 50mm stroke single-acting push cylinder. Air extends the rod to perform work, while an internal spring retracts it, establishing a fail-safe retracted home upon air loss. It delivers a usable push force of 317.7 N at 0.5 MPa and 478.5 N at 0.7 MPa. The exact drop-in replacement is the MSBL32X50U, matching the bore, stroke, G1/8 port, and flat U back cover.
This U-model lacks the -S magnet code and cannot accept a position sensor. As an upgrade fact, the MSAL uses threaded covers and older CS1-M/DS1-M switches, whereas the MSBL replacement features a riveted rolling-packed body and CMSG/DMSG/EMSG sensors. End-of-stroke deceleration relies on a fixed rubber bumper, not an adjustable cushion. Apply no external load on the spring return stroke to prevent bending the 12mm rod.

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X50U carries the same single-acting ratings.
Usable Push Force (Ø32mm)
| Pressure | Push force (net of spring) |
|---|---|
| 0.5 MPa | 317.7 N |
| 0.7 MPa | 478.5 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 MSAL32X50U Is Used
PCB Router Ejection
Deploys 317.7 N at 0.5 MPa to push singulated printed circuit boards out of a routing fixture, relying on the spring return to clear the workspace for the next panel.
Stamping Press Blank Holder
Applies 478.5 N at 0.7 MPa to hold a sheet metal blank in a die before the press cycles, with the fail-safe retracted home ensuring the clamp opens if air pressure drops.
Conveyor Diverter Gate
Extends 50mm to push aluminum extrusions onto a secondary packaging line, using the single-acting push design to simplify wiring to one 3/2 valve.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL32X50U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X50U
To replace this MSAL32X50U, confirm the 32mm bore, 50mm stroke, PT G1/8 port, M10x1.25 rod thread, and flat U back cover. The drop-in MSBL32X50U matches these exactly, though you must update your sensor choice if upgrading from an older -S SKU (CS1-M/DS1-M to CMSG/DMSG/EMSG). Ensure your air supply meets the 0.2 MPa minimum to overcome the return spring.
If sizing a new layout, step down to a 25mm bore for 176.4 N push at 0.5 MPa, or step up to a 40mm bore for 539.9 N at 0.5 MPa. At 50mm stroke on this 32mm bore, side-load is minimal, but always guide the rod-end to prevent seal wear.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X50U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X50U instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL32X50U FAQ
Yes, the MSAL32X50U is discontinued. The exact drop-in replacement is the MSBL32X50U, which matches the 32mm bore, 50mm stroke, G1/8 port, and flat U back cover. The MSBL upgrades the body to a riveted rolling-packed design.
The usable push force (net of the return spring) is 317.7 N at 0.5 MPa and 478.5 N at 0.7 MPa. The operating pressure range is 0.2-1.0 MPa, with a 0.2 MPa minimum required for air to overcome the internal spring and extend the rod.
