This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL40X325U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL40X325U 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-MAL40X325U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 325mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL40X325U, which matches its bore, stroke, force and mounting.
The AirTAC B01-MAL40X325U 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 MAL40X325U, meaning it is mechanically identical to the standard catalog model. Delivering 628 N of push force at 0.5 MPa over a 325 mm stroke, it is now replaced by the MBL40X325U.
The MBL40X325U serves as the exact drop-in replacement, matching the 40 mm bore, G1/4 port, and U flat-end back cover. A key upgrade in the MBL is the riveted rolling-packed body, which supersedes the threaded front and back covers found on this legacy MAL. Because this specific SKU lacks the -S magnet option, it cannot accept a position sensor; buyers needing detection on the new MBL must order the -S version and use current CMSG, DMSG, or EMSG switches.

| Max (@1.0 MPa) | 128 kgf | |
The B01-MBL40X325U 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 a 325 mm travel diverter arm on a packaging conveyor, utilizing the 628 N push force at 0.5 MPa to reliably slide heavy cardboard cartons onto a secondary belt.
Acts as a 325 mm stroke pusher to advance raw metal stock into a lathe collet, where the rigid U flat-end back cover ensures straight axial alignment without arcing.
Raises a small parts elevator tray 325 mm between machine levels; the 880 N thrust at 0.7 MPa easily overcomes the tray weight and component payload.
To replace the B01-MAL40X325U, order the MBL40X325U, ensuring you keep the PT thread, U flat-end back cover, and 325 mm stroke. If your application requires end-of-stroke cushioning beyond the fixed rubber bumper found on both the MAL and standard MBL, step up to the MBLC40X325U which adds an adjustable air cushion. If sizing force, the 32 mm neighbor provides 402 N push at 0.5 MPa, while stepping up is not an option as 40 mm is the largest MAL/MBL mini round bore. Since the stroke is 325 mm, the 16 mm rod is susceptible to bending under lateral stress; use an external guide rail or a pivot mount to manage side loads. Note that neither the MAL nor the MBL holds position automatically—install an external rod lock or pilot-operated check valve if gravity or air loss could cause the load to drift.
Upgrade checklist
Yes, the B01-MAL40X325U is discontinued. The exact drop-in replacement is the MBL40X325U, which matches the 40 mm bore, 325 mm stroke, 628 N push force, G1/4 port, and U flat-end cover. The "B01-" prefix simply designated an application-specific build of the standard MAL40X325U, so the standard MBL replacement fits identically.
The full force set is: 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum theoretical force of 128 kgf at 1.0 MPa. It uses a fixed rubber bumper, not an adjustable cushion or a locking mechanism, so the cylinder cannot hold a load in place if air pressure is lost.
