This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement B01-MBL25X250U, 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-MAL25X250U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 250mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the B01-MBL25X250U, which matches its bore, stroke, force and mounting.
The AirTAC B01-MAL25X250U is a discontinued double-acting aluminum mini round cylinder. The leading B01- prefix marks this as an application-dedicated, customer-specified variant of the base MAL25X250U; mechanically, the bore, 250 mm stroke, porting, and output forces are identical to the standard model. Delivering 245 N push and 206 N pull at 0.5 MPa, it is built for compact spaces requiring a 10 mm piston rod and G1/8 port.
AirTAC replaced this legacy unit with the MBL25X250U, a direct replacement retaining the exact same stroke, force, and U flat-end rear cover. The original MAL features threaded front and back covers, whereas the current MBL utilizes a riveted rolling-packed body. Furthermore, because this specific SKU lacks the -S magnet option, it cannot accept any position sensor. The internal piston relies on a heterogeneous two-way seal that retains grease, paired with a self-lubricating front-cover bearing guide to support the 10 mm carbon-steel rod.

Uses the 245 N push force at 0.5 MPa to deflect pouches on a packaging line, fitting into tight 25 mm bore clearances where a larger profile cylinder would obstruct the belt.
Extends 250 mm to push singulated printed circuit boards out of a routing station, relying on the U flat-end cover for rigid alignment against the ejection chute.
Cycles at 30-800 mm/s to push rejected small plastic parts into a reject bin, where the compact aluminum body and G1/8 port minimize the footprint on the sorting manifold.
To replace the B01-MAL25X250U, order the MBL25X250U. This direct upgrade matches the 25 mm bore, 250 mm stroke, PT thread, G1/8 port, and U flat-end back cover exactly. If you need to adjust the force, stepping down to a 20 mm bore drops the 0.5 MPa push force to 157 N, while stepping up to a 32 mm bore increases it to 402 N. Note that because this SKU has no -S magnet, you cannot mount a position sensor; if you require sensing on the new MBL, you must add the -S option and migrate to the modern CMSG, DMSG, or EMSG switch families, as the older CS1-M and DS1-M sensors are incompatible with the new line.
At 250 mm of stroke, the 10 mm rod is susceptible to bending under side-loads; use an external guide rail or a pivot mount to prevent premature seal wear. The MAL uses a fixed rubber bumper, not an adjustable cushion—if your application requires end-of-stroke deceleration, specify the MBLC variant on the current line. Finally, a plain cylinder does not hold its position when air pressure is lost; the rod will drift, so add an external rod lock or pilot-operated check valve if load holding is critical.
Upgrade checklist
Yes, the B01-MAL25X250U is discontinued. The direct replacement is the MBL25X250U. The B01- prefix simply denotes an application-dedicated variant of the standard MAL25X250U, and the MBL25X250U matches it exactly on bore, stroke, force, port, and U flat-end cover. The main physical change is that the MBL uses a riveted rolling-packed body instead of the older threaded covers.
At 0.5 MPa, the 25 mm bore provides 245 N push and 206 N pull force. At 0.7 MPa, the push force is 343 N, with a maximum theoretical force of 50 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept any position sensor. If you need position detection on the MBL replacement, you must order the -S version and use the current CMSG, DMSG, or EMSG switches.
