This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL20X35CA, 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 MSAL20X35CA
The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X35CA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 35mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X35CA.

About the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X35CA
The AirTAC MSAL20X35CA is a discontinued single-acting push, spring-return mini cylinder. Air extends the 8mm rod for the 35mm work stroke, while an internal spring retracts it to a fail-safe home when air is removed. It delivers a usable push force of 106.8 N at 0.5 MPa. The direct replacement is the MSBL20X35CA, matching the 20mm bore, 35mm stroke, G1/8 port, and CA clevis mount.
This CA back cover features a pivot eye that swings on a pin to absorb arcing rod loads. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor. When upgrading to the MSBL, note the construction shifts from threaded covers to a riveted rolling-packed body. End-of-stroke deceleration relies on a fixed rubber bumper, as no adjustable cushion exists in this single-acting series.

| 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X35CA 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 MSAL20X35CA Is Used
PCB Ejector Pin
Pushes bare circuit boards out of an SMT test fixture using 106.8 N at 0.5 MPa, relying on the spring return to retract safely when air is cut.
Light-Duty Part Clamp
Holds a small plastic housing against a machining stop; the CA pivot absorbs angular misalignment while the fixed bumper stops the stroke cleanly.
Diverter Gate Actuator
Extends to deflect thin cardboard cartons on a packaging conveyor, with the fail-safe spring home ensuring the gate clears the line during an air loss event.
Replacing the Airtac MSAL Front Single Acting Compact Cylinder MSAL20X35CA with AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X35CA
To replace this MSAL20X35CA, order the MSBL20X35CA. Confirm the 20mm bore, 35mm stroke, G1/8 PT port, M8x1.25 rod thread, and CA pivot back cover. Since this SKU has no -S magnet, it cannot hold a sensor; if you need position detection on the new unit, specify an MSBL -S model and upgrade to the modern CMSG, DMSG, or EMSG switches, as the older CS1-M/DS1-M series is obsolete. Remember the 0.2 MPa minimum operating pressure required to overcome the return spring, and apply no external load on the return stroke.
Sizing checks: if 106.8 N at 0.5 MPa is insufficient, step up to the 25mm bore (176.4 N at 0.5 MPa). If you need less force to prevent part damage, the 20mm is the smallest available in this family. With a 35mm stroke, side-load risks are low, but ensure the CA clevis pivot is aligned to prevent rod binding.
Upgrade checklist
- ✓ Order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X35CA (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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X35CA instead of this discontinued model.
Airtac MSAL Front Single Acting Compact Cylinder MSAL20X35CA FAQ
Yes, the MSAL20X35CA is discontinued. The direct replacement is the MSBL20X35CA. It matches the 20mm bore, 35mm stroke, G1/8 port, and CA clevis mount. The main upgrade differences are that the MSBL uses a riveted rolling-packed body instead of threaded covers, and if you need a magnet, it uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M.
This single-acting push cylinder provides a usable force of 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa (maximum 17.3 kgf). The operating pressure range is 0.2-1.0 MPa, but you must maintain at least 0.2 MPa for the air to overcome the internal return spring. There is no pull force, as the spring handles the retraction stroke.
