This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X50-S-CA-LB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X50-S-CA-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-CA-LB (Discontinued) -> MBL40X50-S-CA-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-CA-LB, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X50-S-CA-LB is a discontinued double-acting aluminum mini round cylinder. As the largest bore in the MAL family, it delivers a robust 628 N push force at 0.5 MPa, utilizing a 16 mm carbon-steel rod with 20 um hard chrome plating. The exact drop-in replacement is the MBL40X50-S-CA-LB, matching the 40 mm bore, 50 mm stroke, G1/4 port, LB foot mount, and CA pivot back cover for seamless retrofitting.
This legacy unit features a built-in -S magnet for position sensing. Because of the lifecycle upgrade, note that the original MAL threaded front and back covers were replaced by a riveted rolling-packed body on the MBL. Furthermore, your older CS1-M or DS1-M reed switches will not mount on the new cylinder; the MBL replacement requires the current CMSG, DMSG, or EMSG sensor family. The MAL relies on a fixed rubber bumper, not an adjustable cushion, and a heterogeneous two-way seal retains grease for long service life.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X50-S-CA-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-CA-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.

Uses the 628 N push force at 0.5 MPa to deflect heavy wood pallets onto a side spur track, relying on the CA pivot back cover to accommodate the arc of the redirecting arm.
Drives a folding blade to close heavy double-walled cardboard flaps, where the 50 mm stroke provides rapid, compact movement and the LB foot mount stabilizes the cylinder against direct impact.
Pushes a secondary ejection pin to free stubborn plastic parts from a mold cavity, requiring the 128 kgf maximum theoretical force and the self-lubricating front-cover bearing guide to prevent rod binding.
To replace the MAL40X50-S-CA-LB, order the MBL40X50-S-CA-LB. Verify your porting is G1/4 and your rod-end thread is M12x1.25. You must keep the CA pivot back cover if your machine linkage swings on a pin, and reuse the LB foot mounting bracket. Plan to upgrade your position detection, as the -S magnet on the MBL works only with CMSG, DMSG, or EMSG switches, not the legacy CS1-M or DS1-M. If you need end-of-stroke deceleration, step up to the MBLC variant which adds an adjustable air cushion the MAL never had.
When sizing, verify if 628 N push at 0.5 MPa is correct for your job. Stepping down to the 32 mm bore drops output to 402 N push, while stepping up is impossible within this mini series (40 mm is the maximum bore). Remember that a plain bumper does not hold the load if air pressure drops; for vertical or gravity-driven loads, install an external pilot-operated check valve.
Upgrade checklist
Yes, the MAL40X50-S-CA-LB is discontinued. The exact drop-in replacement is the MBL40X50-S-CA-LB, which shares the same 40 mm bore, 50 mm stroke, G1/4 port, LB foot mount, and CA pivot back cover. You must update your sensors, as the MBL uses CMSG, DMSG, or EMSG switches instead of the older CS1-M or DS1-M models.
The MAL40X50-S-CA-LB is double-acting and delivers 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. It uses a fixed rubber bumper for end-of-stroke damping, not an adjustable cushion; if you need adjustable cushioning, you must upgrade to the MBLC series.
