This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X55SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X55SU 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 MAL40X55SU (Discontinued) → MBL40X55SU is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 55mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X55SU, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X55SU is a discontinued double-acting aluminum mini round cylinder with a 40 mm bore and 55 mm stroke. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa, operating at speeds of 30-800 mm/s. The exact drop-in replacement is the MBL40X55SU, which matches the bore, stroke, output force, G1/4 port, and U flat-end back cover for a seamless retrofit.
This legacy SKU features a built-in magnet (-S) for position detection and a U flat-end rear cover for rigid mounting. The original 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 MAL works with older CS1-M / DS1-M switches; upgrading to the MBL means transitioning to the current CMSG / DMSG / EMSG sensor family. The cylinder relies on a fixed rubber bumper, so if your application requires adjustable end-of-stroke cushioning, you should step up to the MBLC variant on the current line.

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The MBL40X55SU 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 film carriage clamp on a stretch wrap machine, using the 628 N push force at 0.5 MPa to securely grip the stretch film web before the rotation cycle begins.
Folds the major flaps of corrugated shipping cartons on a packaging line, utilizing the 55 mm stroke and U flat-end cover to maintain rigid alignment during the folding stroke.
Deploys a hard stop block for cutting aluminum extrusion profiles to length, where the 528 N pull force safely retracts the 16 mm rod clear of the saw blade after the cut.
To replace the MAL40X55SU, order the MBL40X55SU. Confirm the 40 mm bore, 55 mm stroke, G1/4 port, PT thread, U flat-end back cover, and the -S magnet are correct for your fixture. Because this SKU includes the -S magnet, note that your existing CS1-M or DS1-M reed switches must be replaced by CMSG, DMSG, or EMSG sensors to function on the new MBL body. If you need to adjust bore size, stepping down to the 32 mm bore yields 402 N of push force at 0.5 MPa, while no larger standard mini-round bore exists in this family. If your mechanism requires adjustable air cushions rather than the fixed rubber bumper found here, specify the MBLC40X55SU instead.
Remember that a plain double-acting cylinder does not hold its load when air pressure drops; the rod will drift. For vertical or gravity-loaded applications, install an external pilot-operated check valve or a dedicated rod lock. Furthermore, the 16 mm carbon-steel rod with its 20 um hard-chrome plating offers limited side-load tolerance, so rely on the rigid U flat-end cover only for perfectly aligned assemblies.
Upgrade checklist
Yes, the MAL40X55SU is discontinued. The exact drop-in replacement is the MBL40X55SU. It provides the same 40 mm bore, 55 mm stroke, G1/4 port, U flat-end cover, and -S magnet. The main differences are that the MBL uses a riveted rolling-packed body instead of threaded covers, and the MBL magnet requires CMSG, DMSG, or EMSG switches instead of the older CS1-M or DS1-M sensors.
The 40 mm bore provides a push force of 628 N and a pull force of 528 N at 0.5 MPa. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa. It operates on filtered air at 0.1-1.0 MPa with a fixed rubber bumper at the end of stroke.
