This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X300-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X300-S-U in place of this model. The MBL replacement upgrades to a riveted rolling-packed body and the current CMSG / DMSG / EMSG sensor switches (the MAL used CS1-M / DS1-M).
The AirTAC AirTAC MAL40X300-S-U (Discontinued) -> MBL40X300-S-U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 300mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X300-S-U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X300-S-U is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 300mm stroke. It delivers a push force of 628 N and a pull force of 528 N at 0.5 MPa, operating via a G1/4 port. AirTAC replaced this legacy series with the MBL40X300-S-U, a drop-in alternative retaining the exact bore, stroke, output force, port size, and mounting interface.
This SKU features a built-in magnet (-S) for position detection and a U flat-end back cover for rigid rear mounting. The original MAL body uses threaded front and back covers, whereas the MBL replacement utilizes a riveted rolling-packed body. Furthermore, the -S magnet on this MAL works with older CS1-M or DS1-M switches, while the MBL successor requires the current CMSG, DMSG, or EMSG sensor family.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X300-S-U carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X300-S-U produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

| 40 | Bore size in mm (20/25/32/40). |
| ×300 | Stroke length in mm. |
| S | Optional magnet for a CS1-M / DS1-M sensor (MBL uses CMSG/DMSG/EMSG). |

Replacement mapping: MAL → MBL, MSAL → MSBL, MTAL → MTBL, MALD → MBLD, MALJ → MBLJ.
Uses the 628 N push force at 0.5 MPa to positively divert heavy corrugated cartons on a packaging conveyor without stalling.
Drives a 300mm stroke to open and close heavy machine tool safety doors, relying on the U flat-end cover for rigid frame mounting.
Folds cardboard flaps on large pallet loads, where the 880 N push force at 0.7 MPa easily overcomes box resistance.
To replace the MAL40X300-S-U, order the MBL40X300-S-U, ensuring you keep the 40mm bore, 300mm stroke, G1/4 port, PT thread, U flat-end back cover, and -S magnet. Because the -S magnet is present, note that your legacy CS1-M or DS1-M switches must be upgraded to CMSG, DMSG, or EMSG sensors for the MBL. If you need to step down, the 32mm bore neighbor provides 402 N push at 0.5 MPa; if you need more force, 40mm is the largest available MAL size. At 300mm, the 16mm rod has low side-load tolerance, so use an external guide or pivot to prevent rod bending. The fixed rubber bumper softens end-of-stroke impact but is not an adjustable cushion; for adjustable cushioning, specify the MBLC. A plain cylinder drifts when air is lost, so add a rod lock for position holding.
Upgrade checklist
Yes, the MAL40X300-S-U is discontinued. The exact drop-in replacement is the MBL40X300-S-U, which matches the 40mm bore, 300mm stroke, 628 N push force, G1/4 port, and U flat-end mounting. You must upgrade your CS1-M or DS1-M sensors to the CMSG, DMSG, or EMSG family for the new cylinder.
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force is 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
