This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X50-S-CM-LB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X50-S-CM-LB 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 MAL40X50-S-CM-LB (Discontinued) -> MBL40X50-S-CM-LB is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 50mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X50-S-CM-LB, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X50-S-CM-LB is a discontinued double-acting aluminum mini round cylinder engineered for compact spaces. Delivering 628 N of push force and 528 N of pull force at 0.5 MPa, it utilizes a 16 mm carbon-steel rod with 20 um hard chrome plating and a heterogeneous two-way seal that retains grease for lasting friction reduction. The exact drop-in replacement is the MBL40X50-S-CM-LB, matching the 40 mm bore, 50 mm stroke, G1/4 port, and LB mounting footprint.
This legacy SKU includes a built-in magnet (-S) for position detection, originally designed for CS1-M / DS1-M switches, whereas the modern MBL replacement utilizes CMSG / DMSG / EMSG sensors. The MAL features threaded front and back covers, while the newer MBL body uses a riveted rolling-packed construction. Fitted with a CM round-end back cover and an LB foot mounting bracket, it relies on a fixed rubber bumper for end-of-stroke deceleration rather than an adjustable air cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X50-S-CM-LB carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X50-S-CM-LB 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.

Steers small totes on a 24V conveyor using 628 N of push force at 0.5 MPa, fitting within tight 40 mm frame clearances.
Secures printed circuit boards during routing with the LB foot bracket absorbing vibration, while the -S magnet confirms clamp closure.
Folds minor flaps on small packaging lines, where the 528 N pull force at 0.5 MPa reliably retracts the 16 mm rod within the cycle time.
To replace the MAL40X50-S-CM-LB, order the MBL40X50-S-CM-LB to guarantee a drop-in fit for the 40 mm bore, 50 mm stroke, G1/4 port, and LB foot bracket. Because this SKU includes the -S magnet, remember that your legacy CS1-M or DS1-M reed switches must be upgraded to the current CMSG, DMSG, or EMSG sensor family. The CM round-end back cover pairs with the LB foot bracket to handle slight axial misalignment, but the fixed rubber bumper is not an adjustable cushion; if your application needs precise end-of-stroke deceleration, step up to the MBLC variant on the current line.
For sizing flexibility, stepping down to the 32 mm bore drops the 0.5 MPa push force to 402 N, while no larger standard mini-round bore exists in this family. At 50 mm stroke, side-load risks are minimal, but always ensure the LB bracket is rigidly mounted. A plain MBL does not hold its load when air pressure is lost; the rod will drift, so deploy an external pilot-operated check valve if you need static position holding.
Upgrade checklist
Yes, the AirTAC MAL40X50-S-CM-LB is discontinued. The exact drop-in replacement is the MBL40X50-S-CM-LB, which shares the same 40 mm bore, 50 mm stroke, G1/4 port, LB mounting, and CM round-end back cover. You must upgrade your position sensors, as the legacy CS1-M / DS1-M switches are replaced by CMSG / DMSG / EMSG switches on the MBL.
This 40 mm bore cylinder features a G1/4 port and an M12x1.25 rod-end thread. It generates 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum theoretical force of 128 kgf at 1.0 MPa.
