This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL40X400SCMLB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL40X400SCMLB 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 MAL40X400SCMLB (Discontinued) → MBL40X400SCMLB is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 400mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL40X400SCMLB, which matches its bore, stroke, force and mounting.
The AirTAC MAL40X400SCMLB is a discontinued double-acting aluminum mini round cylinder with a 40mm bore and 400mm stroke. Built for compact spaces, it delivers a push force of 628 N at 0.5 MPa and 880 N at 0.7 MPa. AirTAC replaced this legacy unit with the MBL40X400SCMLB, a drop-in alternative retaining the exact same force, G1/4 port, and LB foot mount. The original MAL body featured threaded front and back covers, whereas the modern MBL uses a riveted rolling-packed body for equally robust performance.
This specific SKU includes a built-in magnet (-S) for position sensing. On the MAL, this magnet pairs with older CS1-M or DS1-M switches, but the MBL replacement transitions to the current CMSG, DMSG, or EMSG sensor families. The 16mm carbon-steel rod has 20 um hard-chrome plating and relies on a heterogeneous two-way seal that retains grease. Because the stroke reaches 400mm, the limited side-load tolerance of the 16mm rod means an external guide rail is recommended to prevent rod bending under offset loads.

The MBL40X400SCMLB 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.

Pushes 50kg cardboard pallets sideways at 400mm stroke on a packaging line, utilizing the 628 N push force to overcome friction without requiring a full-size ISO cylinder.
Acts as a hard stop for advancing PCB panels in a wave soldering machine, where the compact 40mm round body fits between tight conveyor belts and the -S magnet confirms the stop is raised.
Extends 400mm to position a fabric guide roll in automated textile machinery, using the LB foot mount to anchor firmly against the high vibration of the weaving process.
To replace the MAL40X400SCMLB, order the MBL40X400SCMLB. Verify that your 400mm stroke, G1/4 port, PT thread, CM round-end back cover, and LB foot mounting bracket match the new unit. If your application requires position detection, note that your existing CS1-M or DS1-M switches must be upgraded to CMSG, DMSG, or EMSG sensors to match the MBL magnet. The MAL relies on a fixed rubber bumper; if your machine now needs end-of-stroke deceleration for heavier masses, step up to the MBLC series which adds an adjustable air cushion.
For sizing flexibility, you can step down to the 32mm bore (providing 402 N push at 0.5 MPa) if your load is lighter, or step up to a larger profile cylinder if more force is required. At 400mm of travel, the 16mm rod is susceptible to bending under side loads—use a pivot bracket or external linear guide to maintain alignment. Remember that this cylinder uses a fixed rubber bumper, not a lock; a plain MAL or MBL will drift if air pressure is lost, so add a pilot-operated check valve if you need to hold a load vertically.
Upgrade checklist
Yes, the MAL40X400SCMLB is discontinued. The exact drop-in replacement is the MBL40X400SCMLB, which matches the 40mm bore, 400mm stroke, G1/4 port, LB foot mount, and CM round-end cover. The MBL uses a riveted body instead of threaded covers, and your CS1-M/DS1-M sensors must be upgraded to CMSG/DMSG/EMSG switches.
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force increases to 880 N, with a maximum theoretical force of 128 kgf at 1.0 MPa. The operating speed ranges from 30-800 mm/s, operating pressure is 0.1-1.0 MPa, and it uses a fixed rubber bumper for end-of-stroke damping.
