This model is discontinued
AirTAC has phased out the MSAL series. You can still order this code here: we ship the direct replacement MSBL40X50CA, 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).

The AirTAC Airtac MSAL Front Single Acting Compact Cylinder MSAL40X50CA is a single acting, push (spring return) aluminum-barrel mini cylinder with a Ø40mm bore and 50mm stroke, G1/4 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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50CA.
The AirTAC MSAL40X50CA is a discontinued single-acting push, spring-return mini cylinder. Air extends the 16mm rod for the work stroke, while an internal spring retracts it to a fail-safe home when air is removed. This 40mm bore delivers 539.9 N of usable push force at 0.5 MPa (791.1 N at 0.7 MPa). The direct replacement is the MSBL40X50CA, matching the bore, stroke, G1/4 port, and CA clevis.
This SKU features a CA pivot clevis back cover that swings on a pin to absorb arcing loads, and uses a fixed rubber bumper for end-of-stroke damping. It has no -S magnet, meaning it cannot accept a position sensor. During your upgrade to the MSBL, note the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG if you ever add switches, and the construction shifts from these threaded covers to a riveted rolling-packed body.

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 AIRTACMSBLFRONTSINGLEACTINGCOMPACTCYLINDERMSBL40X50CA 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).
Ejects formed sheet metal brackets from a stamping die. The 539.9 N push force at 0.5 MPa clears heavy parts, and the spring return retracts safely when air is cut.
Actuates a heavy diverter gate on a packaging conveyor. The CA clevis accommodates the arcing swing of the gate, while the fail-safe spring return closes the gate on air loss.
Holds injection mold halves aligned during a low-pressure press fit. The fixed rubber bumper absorbs the 50mm stroke impact without requiring adjustment.
To replace this MSAL40X50CA with the MSBL40X50CA, confirm the 40mm bore, 50mm stroke, G1/4 port, PT thread, and CA clevis. Because this is the largest standard MAL bore, you cannot step up within the series; if 539.9 N at 0.5 MPa is insufficient, you must move to a larger ISO cylinder. If you need less force, stepping down to the 32mm bore yields 317.7 N at 0.5 MPa. Remember the 0.2 MPa minimum pressure required to overcome the return spring, and never apply an external load on the spring return stroke. At a 50mm stroke on this 40mm bore, side-load and rod-bending risks are low, but ensure the CA clevis pin is aligned to prevent binding.
Upgrade checklist
Yes, the MSAL40X50CA is discontinued. The direct replacement is the MSBL40X50CA, which matches the 40mm bore, 50mm stroke, G1/4 port, and CA clevis. The MSBL upgrades the body to a riveted rolling-packed design from the original threaded covers.
This single-acting push cylinder delivers 539.9 N at 0.5 MPa and 791.1 N at 0.7 MPa (roughly 80 kgf max). Because the internal return spring opposes the air stroke, the minimum working pressure is 0.2 MPa. It cannot hold a load mid-stroke; the spring drives it to a retracted rest on air loss.
