This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X50-S-U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X50-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 MAL40X50-S-U (Discontinued) → MBL40X50-S-U 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-U, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X50-S-U is a discontinued double-acting aluminum mini round cylinder engineered for compact spaces requiring substantial thrust. Operating at 0.5 MPa, it delivers 628 N of push force and 528 N of pull force. The exact drop-in replacement is the MBL40X50-S-U, matching the 40 mm bore, 50 mm stroke, G1/4 port, and flat-end U cover. This cylinder features a -S magnet for position sensing and a fixed rubber bumper to soften end-of-stroke impacts.
Two structural details distinguish this legacy unit from its modern counterpart. The original MAL body relies on threaded front and back covers, whereas the current MBL replacement utilizes a riveted rolling-packed body for enhanced structural integrity. Furthermore, while the -S magnet on this MAL unit interfaces with legacy CS1-M and DS1-M reed switches, upgrading to the MBL requires migrating to the current CMSG, DMSG, or EMSG sensor families. The 16 mm carbon-steel rod features 20 um hard-chrome plating, supported by a self-lubricating front-cover bearing guide that minimizes friction.

The MBL40X50-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.

Applies 628 N of push force at 0.5 MPa to securely seal aluminum caps onto pharmaceutical vials without cracking the glass.
Utilizes the 16 mm hard-chrome plated rod to actuate secondary tool clamps on machining centers within a 50 mm stroke range.
Employs the flat-end U back cover for rigid mounting, driving a 50 mm diverting stroke to redirect small product pallets on packaging lines.
To replace the MAL40X50-S-U, order the MBL40X50-S-U. Confirm the 40 mm bore, 50 mm stroke, G1/4 port, PT thread form, and the U flat-end back cover are retained. Because this SKU includes the -S magnet, you must update your sensing architecture: the legacy CS1-M and DS1-M switches will not fit the MBL, so plan to install CMSG, DMSG, or EMSG sensors instead. If your application requires adjustable end-cushioning rather than the fixed rubber bumper found on this MAL, step up to the MBLC variant on the current line.
When sizing, verify if 40 mm is the optimal bore. Stepping down to the 32 mm bore drops the 0.5 MPa push force to 402 N, while stepping up is not possible within this mini round family as 40 mm is the largest available size. Because this cylinder relies on a fixed rubber bumper, it cannot hold a load if air pressure drops; implement an external rod lock or pilot-operated check valve for secure position holding.
Upgrade checklist
Yes, the MAL40X50-S-U is discontinued. The exact drop-in replacement is the MBL40X50-S-U, which matches the 40 mm bore, 50 mm stroke, G1/4 port, and U flat-end mounting. Note that the MBL uses a riveted body instead of threaded covers, and you must upgrade from CS1-M/DS1-M switches to CMSG/DMSG/EMSG sensors.
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force reaches 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa. It operates between 0.1-1.0 MPa, runs at speeds of 30-800 mm/s, and uses a fixed rubber bumper rather than an adjustable cushion.
