This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL20X25SCM, 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 MSAL20X25SCM
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25SCM is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 25mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25SCM.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25SCM
The AirTAC MSAL20X25SCM is a discontinued 20mm bore, 25mm stroke single-acting push cylinder with a spring return. Air extends the rod, while an internal spring retracts it, providing a fail-safe retracted home on air loss. It delivers 106.8 N of usable push force at 0.5 MPa and uses an M8x1.25 rod end with a G1/8 port. The direct replacement is the MSBL20X25SCM, matching the bore, stroke, force, and CM round-end back cover.
This SKU includes the -S magnet, which pairs with older CS1-M or DS1-M reed switches. The MSBL upgrade switches to CMSG, DMSG, or EMSG sensors and features a riveted rolling-packed body, replacing this model's older threaded covers. Both generations use a fixed rubber bumper for end-of-stroke damping, meaning there is no adjustable cushion. Because the return spring opposes the air stroke, minimum operating pressure is 0.2 MPa.

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25SCM 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 MSAL20X25SCM Is Used
PCB Ejector Pins
Uses the 106.8 N push force at 0.5 MPa to eject small populated boards from test jigs, relying on the spring return to clear the workspace safely on air loss.
Chip Sorter Gates
Handles 25mm strokes to deflect microchips into packaging tubes; the fail-safe retracted home prevents jamming if the pneumatic supply drops.
Light Plastic Pressing
Applies a brief 169.6 N force at 0.7 MPa to seat plastic clips into housings, with the fixed rubber bumper absorbing the end-stop impact without needing adjustment.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25SCM with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25SCM
To replace this MSAL20X25SCM, use the direct replacement MSBL20X25SCM. Confirm the 25mm stroke, 20mm bore, G1/8 port, PT thread, and CM round-end cover. The -S magnet on your old cylinder used CS1-M/DS1-M switches; the MSBL uses CMSG/DMSG/EMSG sensors. Keep the 0.2 MPa minimum pressure and never apply external loads on the spring return stroke. For a 25mm stroke on this compact 8mm rod, watch for side-load and rod-bending.
If sizing force, this 20mm bore gives 106.8 N at 0.5 MPa. Stepping down is not an option as 20mm is the smallest available. Stepping up to the 32mm bore yields 317.7 N at 0.5 MPa, giving you a much higher push capacity if your fixture allows a larger body.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25SCM (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25SCM instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25SCM FAQ
Yes, the MSAL20X25SCM is discontinued. The direct replacement is the MSBL20X25SCM, matching the 20mm bore, 25mm stroke, 106.8 N push force at 0.5 MPa, G1/8 port, and CM mounting. You will only need to update your sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
This single-acting push cylinder provides 106.8 N of usable force at 0.5 MPa and 169.6 N at 0.7 MPa. Because the internal return spring opposes the air stroke, a minimum operating pressure of 0.2 MPa is required to extend the rod. Maximum proof pressure is 1.5 MPa.
