This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X150CASDB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X150CASDB 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 MSAL40X150CASDB
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X150CASDB is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 150mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X150CASDB.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X150CASDB
The AirTAC MSAL40X150CASDB is a discontinued single-acting push, spring-return mini cylinder. Air extends the rod for the work stroke, while an internal spring retracts it to a fail-safe home on air loss. This 40 mm bore delivers a usable push force of 539.9 N at 0.5 MPa (791.1 N at 0.7 MPa), requiring a minimum 0.2 MPa to overcome the spring. The exact drop-in replacement is the MSBL40X150CASDB, matching the 150 mm stroke, G1/4 port, and SDB mounting.
This SKU features a CA pivot/clevis back cover and an SDB pivot bracket, swinging on a pin to absorb arcing loads. It has no -S magnet, so it cannot take a position sensor. The MSAL uses threaded covers and the older CS1-M/DS1-M switches; the MSBL upgrade features a riveted rolling-packed body and CMSG/DMSG/EMSG sensors. End-of-stroke deceleration uses a fixed rubber bumper, not an adjustable cushion.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X150CASDB Technical Specifications

| Stroke | 150 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X150CASDB 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 MSAL40X150CASDB Is Used
Stamping Press Ejector
Ejects formed sheet metal parts from a die with 539.9 N at 0.5 MPa, relying on the spring return to retract the 16 mm rod when air is cut.
Pivoting Packaging Flap
Uses the CA clevis and SDB bracket to swing a cardboard carton flap, safely returning home if the 0.2 MPa air supply drops.
Woodworking Clamp Arm
Holds a workpiece against a router fence with up to 791.1 N at 0.7 MPa, releasing instantly via the internal spring.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL40X150CASDB with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X150CASDB
To replace this MSAL40X150CASDB, install the MSBL40X150CASDB drop-in. Confirm the 40 mm bore, 150 mm stroke, G1/4 port, PT thread, CA clevis back cover, and SDB pivot bracket. Because this SKU lacks the -S magnet, it cannot accept a sensor; if sensing is needed, specify an MSBL with the -S option and use CMSG/DMSG/EMSG switches. Maintain the 0.2 MPa minimum operating pressure, and apply no external load on the spring return stroke for safety.
If sizing up or down, the 32 mm bore neighbor provides 317.7 N at 0.5 MPa, while the 40 mm here gives 539.9 N. As 40 mm is the largest standard MSAL bore, step down to 32 mm if your load requires less force. For this 150 mm stroke on a small bore, use a pivot mount to prevent side-load rod-bending.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X150CASDB (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X150CASDB instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL40X150CASDB FAQ
Yes, the MSAL40X150CASDB is discontinued. The exact drop-in replacement is the MSBL40X150CASDB, which matches the 40 mm bore, 150 mm stroke, G1/4 port, CA clevis, and SDB mount.
This single-acting push cylinder provides a usable push force of 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa (max 80.6 kgf). It requires a 0.2-1.0 MPa air supply, and the internal spring safely retracts the rod on air loss.
