This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X120SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X120SCA 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 MSAL20X120SCA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X120SCA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 120mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X120SCA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X120SCA
The AirTAC MSAL20X120SCA is a discontinued single-acting push, spring-return mini cylinder. Air extends the 8 mm rod for the 120 mm stroke, while an internal spring retracts it to a fail-safe home when air is removed. It yields a usable push force of 106.8 N at 0.5 MPa. The exact drop-in replacement is the MSBL20X120SCA, matching the 20 mm bore, stroke, G1/8 port, and CA pivot cover.
This SKU includes the -S magnet, which on the MSAL pairs with older CS1-M or DS1-M reed switches. The MSBL replacement upgrades this to CMSG, DMSG, or EMSG sensors and swaps the original threaded covers for a riveted rolling-packed body. A fixed rubber bumper absorbs end-of-stroke impact, as no adjustable cushion is present. The CA back cover acts as a pivot clevis, swinging on a pin to accommodate arcing loads.

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X120SCA 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 MSAL20X120SCA Is Used
PCB Router Ejector
Pushes cut printed circuit boards out of a routing fixture with 106.8 N at 0.5 MPa, letting the internal spring retract the 8 mm rod safely when air drops.
Textile Loom Halt
Swings on its CA pivot clevis to halt a weaving loom arm, absorbing arcing motion before spring-returning to a fail-safe home position.
Packaging Flap Deflector
Deflects cardboard carton flaps on a packaging line; the CS1-M/DS1-M magnet confirms the extended position before the spring pulls back.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X120SCA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X120SCA
To replace this MSAL20X120SCA, order the MSBL20X120SCA. Confirm the 20 mm bore, 120 mm stroke, PT G1/8 port, M8x1.25 rod-end thread, CA pivot back cover, and the -S magnet. Remember that the MSBL sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. Operating pressure must be at least 0.2 MPa to overcome the return spring, and you must apply no external load on the return stroke. At 120 mm on a 20 mm bore, rod-bending side loads are a real risk, so guide the load carefully.
For sizing, stepping down to the 15 mm bore is not an option here, but stepping up to the 25 mm bore increases the usable push force to 176.4 N at 0.5 MPa. If your application needs less force, you would need to step down to a different cylinder family entirely, as 20 mm is the smallest standard MAL bore.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X120SCA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X120SCA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X120SCA FAQ
Yes, the MSAL20X120SCA is discontinued. The exact drop-in replacement is the MSBL20X120SCA, which matches the 20 mm bore, 120 mm stroke, G1/8 port, CA pivot cover, and -S magnet. The MSBL upgrades the sensor family to CMSG/DMSG/EMSG and uses a riveted body instead of threaded covers.
The minimum operating pressure is 0.2 MPa to beat the return spring. The usable push force is 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa, with a maximum of 17.3 kgf. These figures are net of the opposing return spring.
