This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X35CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X35CA 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 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 drop-in 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 drop-in 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.

| Bore size | Ø20 mm |
| Stroke | 35 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 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 exact drop-in 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.
