This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15CA 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 MSAL20X15CA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15CA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 15mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15CA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15CA
The AirTAC MSAL20X15CA is a discontinued single-acting push, spring-return mini cylinder. Air extends the 8mm rod for a 15mm work stroke, while an internal spring retracts it to a fail-safe home when air is removed. It delivers 106.8 N of usable push force at 0.5 MPa and 169.6 N at 0.7 MPa. The exact drop-in replacement is the MSBL20X15CA, matching the 20mm bore, 15mm stroke, G1/8 port, and CA pivot cover.
This SKU features a CA clevis back cover that swings on a pin to absorb arc-style rod movements. Because it lacks the -S suffix, this specific cylinder cannot accept a position sensor. As an upgrade note, the MSAL uses older CS1-M/DS1-M switches and threaded covers, 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 MSAL20X15CA Technical Specifications

| Bore size | Ø20 mm |
| Stroke | 15 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15CA 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 MSAL20X15CA Is Used
PCB Ejector Pins
Pushes bare circuit boards out of an assembly fixture with 106.8 N at 0.5 MPa, relying on the spring return to retract the 15mm stroke clear of the conveyor.
Small Part Sorting Gate
Deflects plastic components on a vibratory bowl feeder track; the CA clevis absorbs slight misalignment, and fail-safe home prevents jams during air loss.
Light-Duty Strip Feed
Indexes thin metal strips into a stamping press. The 15mm stroke provides just enough push without overtravel, and the fixed bumper stops the load cleanly.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15CA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15CA
To replace this MSAL20X15CA, order the MSBL20X15CA. Confirm your 20mm bore, 15mm stroke, G1/8 PT port, M8x1.25 rod-end thread, and CA clevis pivot. The minimum operating pressure is 0.2 MPa to overcome the return spring. If 106.8 N at 0.5 MPa is insufficient, step up to the 25mm bore (176.4 N at 0.5 MPa); if you need less force, the 20mm is the smallest available size. Remember that no external load should be applied during the spring return stroke, and the fixed rubber bumper cannot hold a load mid-stroke.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15CA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15CA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15CA FAQ
Yes, the MSAL20X15CA is discontinued. The exact drop-in replacement is the MSBL20X15CA, which matches the 20mm bore, 15mm stroke, CA clevis, G1/8 port, and single-acting push function. The MSBL upgrades the body to a riveted rolling-packed design but retains the same force class.
The usable push force is 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. This single-acting push cylinder uses air to extend the rod and the spring to retract it.
