This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30CA 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 MSAL40X30CA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30CA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 30mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30CA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30CA
The AirTAC MSAL40X30CA is a discontinued single-acting push cylinder with a 40mm bore and 30mm stroke. Air extends the rod to do work, while an internal spring retracts it to a fail-safe home when air is removed. It delivers 539.9 N of usable push force at 0.5 MPa and 791.1 N at 0.7 MPa. The exact drop-in replacement is the MSBL40X30CA, matching the bore, stroke, G1/4 port, and CA mounting.
This CA variant features a back cover pivot clevis designed to swing on a pin, accommodating arcing loads without side-binding. Because this SKU lacks the -S magnet, it cannot accept a position sensor. Upgrading to the MSBL brings a riveted rolling-packed body instead of these threaded covers, and if sensing is needed, the new line uses CMSG, DMSG, or EMSG switches rather than the older CS1-M or DS1-M. 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 MSAL40X30CA Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30CA |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30CA |
| Bore size | Ø40 mm |
| Stroke | 30 mm |
| Acting type | Single acting, push (spring return) |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30CA 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 MSAL40X30CA Is Used
Stamping Press Ejection
Uses the 539.9 N push force at 0.5 MPa to knock small stamped metal parts out of a die, with the spring safely retracting the rod clear of the tooling between cycles.
Pivoted Flap Gate
Leverages the CA pivot clevis to swing an arc-shaped diverter gate on a packaging line, tolerating the changing rod angle without binding.
Woodworking Clamp Arm
Extends to hold a wooden workpiece against a router fence; on air loss, the spring-return fail-safe home releases the clamp to prevent workpiece damage.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30CA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30CA
To replace this MSAL40X30CA with the MSBL40X30CA, confirm the 40mm bore, 30mm stroke, G1/4 port, PT thread form, and CA pivot clevis. Remember the 0.2 MPa minimum operating pressure required to overcome the return spring, and never apply an external load on the unpowered return stroke. Since this specific SKU has no -S magnet, it cannot support a sensor.
If sizing a new application, step down to a 32mm bore for 317.7 N of push at 0.5 MPa, or step up—though 40mm is the largest available in this mini series. For a 30mm stroke on this 40mm bore, keep the rod guided to prevent bending, as even short strokes can suffer side-load wear if the clevis pin binds.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30CA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X30CA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X30CA FAQ
Yes, the MSAL40X30CA is discontinued. The exact drop-in replacement is the MSBL40X30CA, which matches the 40mm bore, 30mm stroke, G1/4 port, and CA pivot clevis. The MSBL upgrades the body to a riveted rolling-packed design instead of threaded covers.
This single-acting push cylinder provides 539.9 N of usable force at 0.5 MPa, 791.1 N at 0.7 MPa, and a maximum of about 80.7 kgf. The minimum operating pressure is 0.2 MPa, which is required to overcome the internal return spring before the rod can extend.
