This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25CA 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 MSAL20X25CA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25CA 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 drop-in replacement is the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25CA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25CA
The AirTAC MSAL20X25CA is a discontinued single-acting push, spring-return mini cylinder. Air extends the 8mm rod for a 25mm stroke, while an internal spring retracts it to a fail-safe home when air is removed. This 20mm bore delivers a usable push force of 106.8 N at 0.5 MPa. The exact drop-in replacement is the MSBL20X25CA, retaining the same bore, stroke, force class, and CA clevis mounting.
This SKU features a CA pivot back cover that swings on a pin to absorb arcing loads. Because it lacks the -S suffix, it cannot accept a position sensor. Upgrading to the MSBL replaces the older threaded covers with a riveted rolling-packed body. Both generations use a fixed rubber bumper for end-of-stroke damping, as single-acting models lack adjustable cushions.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25CA Technical Specifications
| Model | Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25CA |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25CA |
| Bore size | Ø20 mm |
| Stroke | 25 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25CA 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 MSAL20X25CA Is Used
PCB Ejector Pin
Pushes delicate printed circuit boards out of an inspection fixture using 106.8 N at 0.5 MPa, relying on the spring return to clear the workspace during air loss.
Packaging Flap Deflector
Extends 25mm to guide carton flaps on a rotary packaging line, where the CA clevis absorbs slight arcing motion as the product moves past.
Light-Duty Parts Stop
Acts as a retractable stop gate for small plastic injection parts on a conveyor, dropping back to its fail-safe home position when the airline is vented.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25CA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25CA
To replace this MSAL20X25CA, specify the MSBL20X25CA and confirm the 20mm bore, 25mm stroke, G1/8 PT port, and CA pivot cover. The MSBL also uses a riveted body instead of threaded covers. If your MSAL had a magnet, note the MSBL shifts from CS1-M/DS1-M to CMSG/DMSG/EMSG switches; this no-S SKU takes no sensor. Minimum operating pressure is 0.2 MPa to overcome the return spring, and you must apply no external load on the return stroke.
If sizing your force needs, stepping down is not an option as 20mm is the smallest bore. Stepping up to the 32mm bore gives you 317.7 N at 0.5 MPa if the 106.8 N here is insufficient. With a 25mm stroke on this small bore, side-load and rod-bending risks are minimal, but ensure the CA clevis pivot is aligned to prevent guide wear.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25CA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X25CA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X25CA FAQ
Yes, the MSAL20X25CA is discontinued. The exact drop-in replacement is the MSBL20X25CA, which matches the 20mm bore, 25mm stroke, CA clevis, and 106.8 N push force at 0.5 MPa. The MSBL upgrades the body to a riveted rolling-packed design instead of threaded covers.
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 (maximum 17.3 kgf). The spring provides a fail-safe retracted home, but it is not a lock for holding mid-stroke loads.
