This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X75U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X75U 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 MSAL20X75U
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X75U is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 75mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X75U.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X75U
The AirTAC MSAL20X75U is a discontinued single-acting push, spring-return mini cylinder. Air extends the 8mm rod for the 75mm stroke, while an internal spring drives a fail-safe retracted home on air loss. The exact drop-in replacement is the MSBL20X75U, matching the 20mm bore, G1/8 port, and U flat-end back cover. This 20mm bore yields a usable push force of 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa (net of the return spring).
This U-cover SKU lacks the -S option and cannot accept a position sensor. Upgrading to the MSBL20X75U brings a riveted rolling-packed body instead of the older MSAL threaded covers, and if a magnet is later needed, the MSBL uses modern CMSG/DMSG/EMSG switches rather than the legacy CS1-M/DS1-M. End-of-stroke damping relies on a fixed rubber bumper, not an adjustable cushion. The minimum operating pressure is 0.2 MPa to overcome the return spring.

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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X75U 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 MSAL20X75U Is Used
PCB Depaneling Ejector
Pushes separated printed circuit boards out of a routing fixture with 106.8 N at 0.5 MPa. The spring return safely retracts the pin when air is removed, preventing downstream collision.
Light Sheet Metal Clamp
Holds a thin gauge steel stamping in place during a single-direction riveting pass. The fail-safe retracted home releases the part instantly if compressed air drops.
Packaging Flap Diverter
Extends 75mm to block and redirect small cartons on a packaging conveyor. The fixed rubber bumper absorbs the end-stroke impact without requiring manual adjustment.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X75U with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X75U
To replace the MSAL20X75U, specify the MSBL20X75U to retain the 20mm bore, 75mm stroke, PT G1/8 port, M8x1.25 rod-end thread, and rigid U back cover. Since this is a no-magnet SKU, it cannot take a sensor; if position detection is needed, an MSBL20X75US is required (using CMSG/DMSG/EMSG switches). Ensure your air supply meets the 0.2 MPa minimum to beat the return spring, and apply no external load on the spring return stroke for safety.
For sizing flexibility, stepping down to the next smaller bore is not an option as 20mm is the smallest available. Stepping up to the 32mm bore provides a 317.7 N push at 0.5 MPa if your 75mm stroke ejection needs more force. At 75mm of travel on this compact 20mm body, watch for side-load and rod-bending forces—keep the load guided and purely axial to prevent premature seal wear.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X75U (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X75U instead of this discontinued model.
