This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X155SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X155SCA 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 MAL40X155SCA Discontinued -> MBL40X155SCA is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 155mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X155SCA, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X155SCA is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 155mm stroke. It delivers 628N push and 528N pull at 0.5MPa, utilizing a G1/4 port and an M12x1.25 rod-end thread. The exact drop-in replacement is the MBL40X155SCA, which matches the original bore, stroke, output force, port size, and CA pivot mounting.
This legacy SKU features a built-in -S magnet for position detection and a CA pivot clevis back cover designed to swing on a pin for arcing loads. The older MAL body uses threaded front and back covers, whereas the current MBL replacement utilizes a riveted rolling-packed body. Additionally, the -S magnet on this discontinued unit interfaces with legacy CS1-M or DS1-M switches, while the MBL upgrade requires the modern CMSG, DMSG, or EMSG sensor families.

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X155SCA 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.

Actuates a diverter gate on a packaging conveyor, using the 628N push force at 0.5MPa to redirect heavy cartons.
Secures cast aluminum housings during machining, where the CA pivot clevis accommodates slight misalignment.
Drives a folding arm on a case sealer, relying on the 155mm stroke to clear the packaging path before retracting.
To replace the MAL40X155SCA, order the MBL40X155SCA. Confirm your 40mm bore, 155mm stroke, G1/4 port, and PT tapered thread are correct. Because this SKU includes the -S magnet and CA pivot, note that your existing CS1-M or DS1-M switches must be swapped to CMSG, DMSG, or EMSG sensors for the new body. If your application requires an adjustable air cushion rather than the fixed rubber bumper found on this cylinder, step up to the MBLC series.
For sizing flexibility, stepping down to the 32mm bore yields 402N push at 0.5MPa, while stepping up to the largest available 50mm bore provides higher force. Because the 155mm stroke exceeds 300mm, the 16mm carbon-steel rod has low side-load tolerance; use an external guide or rely on the CA pivot to absorb radial stress. Remember that a plain MAL or MBL cylinder does not hold its load when air is lost, so add an external rod lock for suspended loads.
Upgrade checklist
Yes, the MAL40X155SCA is discontinued. The exact drop-in replacement is the MBL40X155SCA, which shares the same 40mm bore, 155mm stroke, CA pivot mount, G1/4 port, and force ratings. You must only update your position sensors, as the MBL body uses CMSG, DMSG, or EMSG switches instead of the older CS1-M or DS1-M.
At 0.5MPa, it provides 628N push and 528N pull. At 0.7MPa, the push force is 880N, with a maximum theoretical force of 128kgf at 1.0MPa. It uses a fixed rubber bumper for end-of-stroke damping, not an adjustable cushion. If you need adjustable air cushioning, you must use the current MBLC series.
