This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement B01-MBL25X40U, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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 B01-MAL Special Purpose Cylinder B01-MAL25X40U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 40mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the B01-MBL25X40U, which matches its bore, stroke, force and mounting.
The AirTAC B01-MAL25X40U is a discontinued compact double-acting aluminum mini round cylinder. The leading "B01-" prefix marks this as an application-dedicated (customer-specified) variant, though it remains mechanically identical to the standard MAL25X40U. Delivering 245 N of push force at 0.5 MPa, it features a 25 mm bore, 40 mm stroke, and a U flat-end back cover. AirTAC replaced the MAL line with the MBL series, making the MBL25X40U the direct replacement sharing the same force, G1/8 port, and mounting interface.
The legacy MAL body relies on threaded front and rear covers, whereas the modern MBL utilizes a riveted rolling-packed body for structural rigidity. Internally, a heterogeneous two-way seal retains grease, and the carbon-steel piston rod features 20 um hard-chrome plating guided by a self-lubricating bearing. Because this specific SKU lacks the -S magnet code, it cannot accept a position sensor. End-of-stroke deceleration is handled by a fixed rubber bumper, not an adjustable air cushion.

The B01-MBL25X40U produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Replacement mapping: MAL → MBL, MSAL → MSBL, MTAL → MTBL, MALD → MBLD, MALJ → MBLJ.
Pushes a 40 mm stroke pin to eject singulated circuit boards from a routing fixture, using 245 N of force to clear the cut panel safely.
Actuates a short 40 mm mechanical arm to tuck minor flaps on small packaging boxes before tape sealing, fitting within tight side-frame clearances.
Indexes a 25 mm bore rod to push individual glass vials into a centrifuge carousel, relying on the rigid U flat-end cover to maintain strict axial alignment.
To replace the B01-MAL25X40U, order the MBL25X40U. Confirm your 25 mm bore, 40 mm stroke, G1/8 port, and PT thread form. The U flat-end back cover provides rigid axial mounting; if your machine requires arcing motion, switch to the CA pivot clevis instead. Since this SKU lacks an -S magnet, it cannot support a sensor. If you need position detection on the new MBL, add the -S code, but note the sensor family changes from the old CS1-M / DS1-M to the current CMSG / DMSG / EMSG switches.
When sizing, verify if 245 N push at 0.5 MPa is sufficient. Stepping down to the 20 mm bore drops force to 157 N, while stepping up to the 32 mm bore increases it to 402 N. The fixed rubber bumper softens end-of-stroke impacts, but if your load requires adjustable deceleration, specify the MBLC variant on the current line. A plain cylinder drifts when air is lost; add an external rod lock for suspended loads.
Upgrade checklist
Yes, the B01-MAL25X40U is discontinued. The direct replacement is the MBL25X40U, which matches the 25 mm bore, 40 mm stroke, 245 N force, G1/8 port, and U flat-end cover. The "B01-" prefix simply designated an application-specific build of the base MAL25X40U; mechanically, the MBL25X40U is the direct upgrade.
At 0.5 MPa it provides 245 N push and 206 N pull force; at 0.7 MPa push is 343 N, with a maximum theoretical force of 50 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet code, it cannot accept a position sensor. If you need detection on the MBL replacement, add the -S option, which uses the current CMSG / DMSG / EMSG switches instead of the older CS1-M / DS1-M.
