This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X100U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X100U 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).

The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL20X100U is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø20mm bore and 100mm 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X100U.
The AirTAC MSAL20X100U is a discontinued single-acting push cylinder with a 20mm bore and 100mm stroke. Air extends the rod to do its work, while an internal spring retracts it for a fail-safe home when air is removed. It delivers a usable push force of 106.8 N at 0.5 MPa. The exact drop-in replacement is the MSBL20X100U, matching the bore, stroke, G1/8 port, and U flat-end back cover.
This U-cover SKU lacks the -S magnet, so it cannot accept a position sensor. During your upgrade to the MSBL, note the construction changes: the older MSAL uses threaded covers, while the MSBL features a riveted rolling-packed body. The MSAL operates on a 3/2 valve with a 0.2 MPa minimum pressure to overcome the return spring. End-of-stroke deceleration relies on a fixed rubber bumper, not an adjustable cushion.

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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL20X100U carries the same single-acting ratings.

Usable single-acting force after the return spring — lower than a same-bore double-acting cylinder. Size with a margin.

Replacement: MSAL → MSBL. Related: MTAL/MTBL (single-acting pull), MAL/MBL (double acting).
Pushes bare circuit boards out of an SMT test fixture using 106.8 N at 0.5 MPa, relying on the spring return to clear the ejector path during downtime.
Acts as a diverter gate in a vibratory bowl feeder for plastic connectors, extending 100mm to block the lane and retracting safely on air loss.
Depresses a manual ink stamp onto machined aluminum brackets, using the fixed rubber bumper to absorb the 100mm stroke impact without crushing the part.
To replace this MSAL20X100U, specify the MSBL20X100U and confirm the 20mm bore, 100mm stroke, PT G1/8 port, M8x1.25 rod thread, and U flat-end back cover. Because this SKU has no -S magnet, you will need an external sensor bracket if you require position detection, as the MSAL cannot mount CS1-M/DS1-M switches. The MSBL upgrade also shifts the body style from threaded covers to a riveted rolling-packed design.
When sizing, ensure your air supply stays above the 0.2 MPa minimum to beat the return spring, and apply no external load on the return stroke. At 100mm of stroke on a small 20mm bore, watch for side-load and rod-bending forces. If you need less push, the next size down does not exist (20mm is the minimum). If you need more force, step up to the 25mm bore, which provides 176.4 N at 0.5 MPa.
Upgrade checklist
Yes, the MSAL20X100U is discontinued. The exact drop-in replacement is the AirTAC MSBL20X100U. It matches the 20mm bore, 100mm stroke, G1/8 port, and U flat-end back cover. The MSBL upgrades the body to a riveted rolling-packed design instead of threaded covers.
This single-acting push cylinder delivers a usable push force of 106.8 N at 0.5 MPa and 169.6 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring. The maximum push force is approximately 17.3 kgf.
