This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL40X250SCA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL40X250SCA 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-MAL40X250SCA is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 250mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL40X250SCA, which matches its bore, stroke, force and mounting.
The AirTAC B01-MAL40X250SCA is a discontinued double-acting aluminum mini round cylinder built for a 40 mm bore and 250 mm stroke. The leading "B01-" prefix designates this as an application-dedicated, customer-specified variant of the base MAL40X250SCA, meaning it is mechanically identical to the standard model but grouped for specific industrial builds. Delivering 628 N of push force at 0.5 MPa, it is engineered for compact spaces requiring robust actuation. AirTAC replaced the legacy MAL line with the MBL series, making the MBL40X250SCA the exact drop-in replacement—matching the bore, stroke, output force, G1/4 port, and CA pivot mounting.
Two key engineering shifts define the upgrade. First, the legacy MAL uses threaded front and back covers on the barrel, whereas the modern MBL features a riveted rolling-packed body for streamlined assembly. Second, this SKU includes a built-in magnet (-S) for position detection; the MAL works with older CS1-M or DS1-M reed switches, while the MBL replacement transitions to the current CMSG, DMSG, or EMSG sensor families. The cylinder relies on a fixed rubber bumper for end-of-stroke damping and uses a heterogeneous two-way seal that retains grease around the 16 mm carbon-steel rod.

The B01-MBL40X250SCA 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.

Drives the 250 mm stroke to shift weaving beams into loading cradles, utilizing the 628 N push force at 0.5 MPa to move heavy fabric rolls while the CA pivot absorbs frame misalignment.
Actuates a diverter arm on a packaging line to route boxes, where the 40 mm bore provides enough thrust to push corrugated cartons and the magnet confirms stroke endpoints for timing.
Ejects plastic totes from accumulation rollers in compact sortation modules, relying on the 880 N push force at 0.7 MPa to overcome sliding friction without stalling.
To replace this discontinued cylinder, order the MBL40X250SCA. Confirm the 40 mm bore, 250 mm stroke, G1/4 port, and PT thread form. This SKU features a CA pivot back cover (clevis) that swings on a pin to accommodate arcing loads, and the -S magnet requires upgrading your CS1-M or DS1-M sensors to CMSG, DMSG, or EMSG switches. If you need adjustable air cushioning instead of the fixed rubber bumper, step up to the MBLC variant on the current line.
When sizing, step down to the 32 mm bore if you need less force (it provides 402 N push at 0.5 MPa), or step up if your application exceeds 128 kgf maximum theoretical force at 1.0 MPa. Because this is a 250 mm stroke, the 16 mm rod has moderate side-load tolerance; for offset loads, rely on the CA pivot to absorb misalignment or add an external guide. Note that a plain cylinder drifts when air is lost—the bumper softens impact but does not lock the rod, so add a pilot-operated check valve for position holding.
Upgrade checklist
Yes, the B01-MAL40X250SCA is discontinued. The exact drop-in replacement is the MBL40X250SCA, which matches the 40 mm bore, 250 mm stroke, force, G1/4 port, and CA pivot mounting. The "B01-" prefix simply marks this as an application-dedicated variant of the base MAL40X250SCA, so the MBL version functions identically. Note that the MBL uses a riveted body instead of threaded covers, and if you use the -S magnet, you must upgrade from CS1-M/DS1-M to CMSG/DMSG/EMSG sensors.
The 40 mm bore cylinder uses a 16 mm carbon-steel rod with an M12x1.25 rod-end thread. At 0.5 MPa it provides 628 N push and 528 N pull force. At 0.7 MPa the push force is 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa. It operates on filtered air between 0.1-1.0 MPa, runs at 30-800 mm/s, and uses a fixed rubber bumper rather than an adjustable cushion.
