This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X20CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X20CM 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 MSAL32X20CM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL32X20CM is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø32mm bore and 20mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X20CM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL32X20CM
The AirTAC MSAL32X20CM is a discontinued single-acting push, spring-return mini cylinder. Air extends the rod for the 20 mm work stroke, while an internal spring retracts it to a fail-safe home when air is removed. It delivers 317.7 N of usable push force at 0.5 MPa. The exact drop-in replacement is the MSBL32X20CM, matching the 32 mm bore, stroke, G1/8 port, and CM mounting.
This MSAL32X20CM features a CM round-end back cover and a PT tapered port thread. Because this SKU lacks the -S magnet code, it cannot accept a position sensor. The legacy MSAL uses threaded covers and older CS1-M / DS1-M switches; upgrading to the MSBL brings a riveted rolling-packed body and CMSG / DMSG / EMSG sensors. End-of-stroke deceleration relies on a fixed rubber bumper, not an adjustable cushion.
Airtac MSAL Front Single Acting Compact Cylinder MSAL32X20CM Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL32X20CM |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X20CM |
| Bore size | Ø32 mm |
| Stroke | 20 mm |
| Acting type | Single acting, push (spring return) |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X20CM 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 MSAL32X20CM Is Used
Circuit Board Ejector
Pushes populated PCBs out of an SMT test fixture with 317.7 N at 0.5 MPa. The spring return guarantees the ejector retracts clear of the conveyor on air loss.
Bottle Flap Diverter
Actuates a short 20 mm diverter flap on a packaging rotary filler. The fail-safe spring return drops the flap to its rest position during an E-stop.
Bearing Press Starter
Initiates a 20 mm press stroke to seat a bearing into an aluminum housing. The fixed rubber bumper absorbs the impact without requiring adjustment.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL32X20CM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X20CM
To replace the MSAL32X20CM, specify the MSBL32X20CM to retain the 32 mm bore, 20 mm stroke, G1/8 port, M10x1.25 rod-end thread, and CM round-end cover. Remember the minimum operating pressure is 0.2 MPa to overcome the return spring. Never apply an external load on the spring return stroke, as it is unpowered and risks bending the 12 mm rod.
If sizing a new application, stepping down to the 25 mm bore yields 176.4 N push at 0.5 MPa, while stepping up to the 40 mm bore provides 539.9 N at 0.5 MPa. The 20 mm stroke on this 32 mm bore keeps the rod highly rigid, minimizing side-load bending risks during short ejection tasks.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X20CM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL32X20CM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL32X20CM FAQ
Yes, the MSAL32X20CM is discontinued. The exact drop-in replacement is the MSBL32X20CM, matching the 32 mm bore, 20 mm stroke, CM cover, and G1/8 port. The MSBL upgrades the body to a riveted rolling-packed design.
The usable push force is 317.7 N at 0.5 MPa and 478.5 N at 0.7 MPa (maximum 48.8 kgf). The operating pressure range is 0.2-1.0 MPa, requiring a minimum of 0.2 MPa to overcome the internal return spring. This SKU has no -S magnet and cannot take a sensor.
