This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X35SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X35SU 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 MAL40X35SU (Discontinued) → MBL40X35SU is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 35mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X35SU, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X35SU is a discontinued double-acting aluminum mini round cylinder. It delivers 628 N of push force at 0.5 MPa via a 40 mm bore and a 35 mm stroke. The exact drop-in replacement is the MBL40X35SU, which matches the original force, G1/4 port, and flat-end U back cover. The legacy MAL body used threaded front and back covers, whereas the modern MBL features a riveted rolling-packed body for equally robust performance.
This specific SKU includes a built-in magnet (-S) and a U-type flat-end back cover. Because it has the -S magnet, it is designed to work with the older CS1-M and DS1-M reed switches for rod position detection; upgrading to the MBL means transitioning to the current CMSG, DMSG, or EMSG sensor families. The piston relies on a heterogeneous two-way seal that retains grease, and the carbon-steel rod has 20 um hard-chrome plating to resist wear.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL40X35SU carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

| Max (@1.0 MPa) | 128 kgf | |
The MBL40X35SU 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.

Provides 628 N of push at 0.5 MPa to eject small plastic parts from tight mold cavities where a compact 40 mm bore is required.
Uses the 35 mm stroke to rapidly actuate a diverting gate on a packaging line, relying on the U flat-end cover for rigid rear mounting.
Moves a testing head into position over a printed circuit board, using the -S magnet and CS1-M sensors to confirm the 35 mm extension.
To replace the MAL40X35SU, order the MBL40X35SU. Confirm your 40 mm bore, 35 mm stroke, G1/4 port, PT thread, U flat-end back cover, and magnet are retained in the new order. If you need to step down in force, the 32 mm bore neighbor provides 402 N of push at 0.5 MPa; stepping up is not possible as 40 mm is the largest MAL mini round cylinder available. The fixed rubber bumper on this cylinder softens the end of stroke but is not an adjustable cushion—if you need end-of-stroke deceleration, look at the MBLC variant on the current line.
Because this is a short 35 mm stroke, side-load bending is minimal, but the 16 mm rod still has low tolerance for off-center loads. Note that a plain double-acting cylinder does not hold its position if air pressure drops—the rod will drift. For safety against drifting loads, install an external rod lock or a pilot-operated check valve.
Upgrade checklist
Yes, the MAL40X35SU is discontinued. The exact drop-in replacement is the MBL40X35SU. It offers the same 40 mm bore, 35 mm stroke, G1/4 port, and U flat-end back cover. The main change is that the MBL uses a riveted rolling-packed body instead of threaded covers, and if you use the -S magnet, you must switch from the old CS1-M/DS1-M switches to the new CMSG/DMSG/EMSG 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 is 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
