This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL20X150U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL20X150U 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 B01-MAL Special Purpose Cylinder B01-MAL20X150U is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 150mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL20X150U, which matches its bore, stroke, force and mounting.
The AirTAC B01-MAL20X150U is a discontinued double-acting aluminum mini round cylinder. The B01- prefix marks this as an application-dedicated, customer-specified variant of the base MAL20X150U, meaning it is mechanically identical to the standard model. Delivering 157 N of push force at 0.5 MPa, its exact drop-in replacement is the current MBL20X150U, which matches the 20 mm bore, 150 mm stroke, G1/8 port, and U flat-end cover.
This legacy cylinder features a fixed rubber bumper and a heterogeneous two-way seal that retains grease for long service life. The original MAL body uses threaded front and back covers, whereas the modern MBL replacement utilizes a riveted rolling-packed body. Because this specific SKU lacks the -S magnet option, it cannot accept a position sensor.

| Max (@1.0 MPa) | 32 kgf | |
The B01-MBL20X150U 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 singulated printed circuit boards out of a routing fixture with 157 N of force, fitting easily into dense electronics assembly machinery.
Actuates a lightweight flap on a conveyor to sort small plastic injection-molded components into packaging chutes.
Extends 150 mm to tamp adhesive labels onto small cosmetic containers, relying on the compact 20 mm body to fit narrow frame gaps.
To replace the B01-MAL20X150U, order the MBL20X150U. It is a true drop-in upgrade retaining the 20 mm bore, 150 mm stroke, PT thread, and U flat-end back cover. If you need to adjust the force, stepping down is not an option as 20 mm is the smallest available bore. Stepping up to the 32 mm bore yields 402 N of push force at 0.5 MPa. Since this SKU has no -S magnet, it cannot support a sensor; if you need position detection, order the MBL20X150S and note that the modern MBL uses CMSG, DMSG, or EMSG switches instead of the older CS1-M/DS1-M family.
At 150 mm of stroke, the 8 mm piston rod has a low tolerance for side loads. Use an external guide rail to prevent rod bending and premature seal wear. The fixed rubber bumper softens the end of travel but is not an adjustable cushion; if your application requires precise end-of-stroke deceleration, look at the MBLC variant on the current line. Furthermore, a plain cylinder does not hold its load if air pressure drops; add an external rod lock or pilot-operated check valve if drifting is unacceptable.
Upgrade checklist
Yes, the B01-MAL20X150U is discontinued. The B01- prefix simply indicates an application-dedicated build of the standard MAL20X150U. The exact drop-in replacement is the MBL20X150U, which matches the 20 mm bore, 150 mm stroke, G1/8 port, and U flat-end cover. The modern MBL uses a riveted rolling-packed body instead of the older threaded covers.
At 0.5 MPa, the push force is 157 N and the pull force is 132 N. At 0.7 MPa, the push force is 220 N. The maximum theoretical force is 32 kgf at 1.0 MPa.
