This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X100SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X100SU 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 MSAL20X100SU
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X100SU is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 100mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X100SU.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X100SU
The AirTAC MSAL20X100SU is a discontinued single-acting push cylinder with a 20mm bore and 100mm stroke. Air extends the rod to perform work, 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. The exact drop-in replacement is the MSBL20X100SU, matching the bore, stroke, and G1/8 port.
This U-back-cover SKU includes the -S magnet for position sensing. The legacy MSAL uses CS1-M or DS1-M reed switches, whereas the MSBL upgrade accepts CMSG, DMSG, or EMSG sensors. The older MSAL features threaded covers, while the modern MSBL uses a riveted rolling-packed body. Both retain a fixed rubber bumper for end-of-stroke damping.

| Bore size | Ø20 mm |
| Stroke | 100 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X100SU 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 MSAL20X100SU Is Used
PCB Router Ejection
Pushes singulated circuit boards out of a routing fixture with 106.8 N at 0.5 MPa. The spring return guarantees the ejector clears the workspace on air loss.
Thin-Wall Plastic Gate
Pivots a lightweight guard open during thermoforming machine indexing. The 100mm stroke provides ample reach, and the fail-safe spring closes the gate safely.
Packaging Flap Deflector
Extends to guide carton flaps during case erecting. The compact 20mm bore fits tight machine frames while delivering reliable 169.6 N at 0.7 MPa.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X100SU with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X100SU
To replace this MSAL20X100SU, install the MSBL20X100SU. Confirm the 20mm bore, 100mm stroke, G1/8 PT port, M8x1.25 rod thread, flat U back cover, and the magnet sensor family change from CS1-M/DS1-M to CMSG/DMSG/EMSG. 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 sizing your circuit, stepping down is not an option as 20mm is the smallest available bore. Stepping up to the 32mm bore provides 317.7 N at 0.5 MPa if you need significantly more clamping power. Because this 100mm stroke is long for a 20mm bore, carefully check side-load alignment to prevent rod bending and premature seal wear.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X100SU (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X100SU instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X100SU FAQ
Yes, the MSAL20X100SU is discontinued. The exact drop-in replacement is the MSBL20X100SU, which matches the 20mm bore, 100mm stroke, G1/8 port, and U back cover. You will only need to update your position sensors, as the MSBL uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M reeds.
This single-acting push cylinder requires a minimum of 0.2 MPa to overcome the return spring. It delivers a usable push force of 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa (max 17.3 kgf). The operating pressure range is 0.2-1.0 MPa, and it uses a fixed rubber bumper rather than an adjustable cushion.
