This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL20X15SCM, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 MSAL20X15SCM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15SCM 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 direct replacement is the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15SCM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15SCM
The AirTAC MSAL20X15SCM is a discontinued single-acting push, spring-return mini cylinder. Air extends the rod for a 15 mm work stroke, while an internal spring retracts it to a fail-safe home when air is released. The direct replacement is the MSBL20X15SCM, which matches the 20 mm bore, 15 mm stroke, G1/8 port, and CM round-end back cover. This SKU provides a usable push force of 106.8 N at 0.5 MPa (169.6 N at 0.7 MPa), needing only a 3/2 valve and a 0.2 MPa minimum pressure to beat the return spring.
This MSAL20X15SCM includes the -S magnet for position sensing with older CS1-M or DS1-M switches; upgrading to the MSBL20X15SCM shifts you to CMSG, DMSG, or EMSG sensors. The MSAL uses threaded covers, whereas the MSBL replacement features a riveted rolling-packed body. Both share a fixed rubber bumper for end-of-stroke damping. Remember that the spring return is for cycling only—apply no external load on the return stroke, as it is a fail-safe rest, not a powered lock.

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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15SCM 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 MSAL20X15SCM Is Used
PCB Ejector Pins
Uses the 106.8 N push force at 0.5 MPa to eject small printed circuit boards from a test fixture, relying on the 15 mm stroke and fail-safe spring return to clear the bay when air drops.
Chip Tray Stops
Acts as a compact stop gate on a semiconductor wafer conveyor, where the 20 mm bore and CM round-end fit tight tracks and the spring return retracts the stop instantly on valve release.
Light Stamping Press
Executes a 15 mm short stamping cycle on thin foils or labels, using the 169.6 N push force at 0.7 MPa before the fixed rubber bumper halts the stroke and the spring brings the tool home.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15SCM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15SCM
To replace the MSAL20X15SCM, install the direct replacement MSBL20X15SCM. Confirm the 20 mm bore, 15 mm stroke, PT G1/8 port, CM round-end back cover, and M8x1.25 rod-end thread. Because this SKU has the -S magnet, note the sensor family change: the MSAL's CS1-M/DS1-M switches become CMSG/DMSG/EMSG on the MSBL. Maintain the 0.2 MPa minimum operating pressure and never apply external load to the spring return stroke.
If sizing force, this 20 mm bore yields 106.8 N at 0.5 MPa. Stepping up to the 25 mm bore gives 176.4 N at 0.5 MPa for heavier ejection, while 20 mm is the smallest available size in this series. The 15 mm stroke is very short, keeping rod-bending side-load risks minimal, but always ensure pure axial pushing to protect the 8 mm hard-chrome rod and self-lubricating guide.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15SCM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X15SCM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X15SCM FAQ
Yes, the MSAL20X15SCM is discontinued. The direct replacement is the MSBL20X15SCM, matching the 20 mm bore, 15 mm stroke, G1/8 port, and CM mounting. You will need to upgrade your sensors from the old CS1-M/DS1-M switches to the CMSG/DMSG/EMSG family, and the body changes from threaded covers to a riveted rolling-packed design.
The 20 mm bore single-acting push force is 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa. It requires a 0.2 MPa minimum air pressure to overcome the internal return spring, operates at 50-800 mm/s, and uses a fixed rubber bumper. The spring provides a fail-safe retracted home, not a mid-stroke load lock.
