This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30CA 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 MSAL20X30CA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30CA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 30mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30CA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30CA
The AirTAC MSAL20X30CA is a discontinued single-acting push, spring-return mini cylinder. Air extends the Ø20 mm rod for a 30 mm stroke, while an internal spring retracts it to a fail-safe home when air is removed. It delivers a usable push force of 106.8 N at 0.5 MPa (169.6 N at 0.7 MPa). The exact drop-in replacement is the MSBL20X30CA, matching the bore, stroke, G1/8 port, and CA mounting.
This SKU features a CA pivot clevis back cover that swings on a pin to accommodate arcing loads. It has no -S magnet, so it 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.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30CA Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30CA |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30CA |
| Bore size | Ø20 mm |
| Stroke | 30 mm |
| Acting type | Single acting, push (spring return) |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30CA carries the same single-acting ratings.
Usable Push Force (Ø20mm)
| Pressure | Push force (net of spring) |
|---|---|
| 0.5 MPa | 106.8 N |
| 0.7 MPa | 169.6 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 MSAL20X30CA Is Used
Packaging Flap Sealing
Extends a 30 mm stroke to press cardboard carton flaps during the taping sequence, with the spring ensuring the arm lifts clear if air pressure drops.
Small Part Ejection
Pushes light plastic mouldings out of a machining fixture using 106.8 N of push force at 0.5 MPa before retracting to clear the workspace.
Pivot Lever Clamping
Uses the CA clevis to swing a 20 mm bore arm into position, holding a sheet metal bracket during a spot-welding operation.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30CA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30CA
To replace the MSAL20X30CA, order the MSBL20X30CA. Confirm the 20 mm bore, 30 mm stroke, G1/8 port, PT thread form, and CA clevis. Because this SKU lacks the -S magnet, it cannot hold a sensor; if you need position detection, specify an MSBL with the -S option to use CMSG/DMSG/EMSG switches. Remember the 0.2 MPa minimum operating pressure required to overcome the return spring, and apply no external load on the spring return stroke.
If you need more force, step up to the 25 mm bore (176.4 N at 0.5 MPa). If you need less force, 20 mm is the smallest available size in this series. For a 30 mm stroke on this small bore, verify side-load alignment to prevent rod-bending and premature guide wear.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30CA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X30CA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X30CA FAQ
Yes, the MSAL20X30CA is discontinued. The exact drop-in replacement is the MSBL20X30CA, which matches the 20 mm bore, 30 mm stroke, CA clevis, and G1/8 port. The MSBL upgrades the body to a riveted rolling-packed design.
The usable push force is 12.6 N at 0.2 MPa, 75.4 N at 0.4 MPa, 106.8 N at 0.5 MPa, and 169.6 N at 0.7 MPa (max 17.3 kgf). The minimum operating pressure is 0.2 MPa because the air must overcome the internal return spring.
