This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL40X175U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL40X175U 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-MAL40X175U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 175mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL40X175U, which matches its bore, stroke, force and mounting.
The AirTAC B01-MAL40X175U 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 MAL40X175U, meaning it is mechanically identical to the standard catalog model. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa, utilizing a 16 mm carbon-steel rod with 20 um hard-chrome plating guided by a self-lubricating front-cover bearing. Because this SKU lacks the -S magnet code, it cannot accept a position sensor.
AirTAC replaced the legacy MAL line with the MBL series, making the MBL40X175U the exact drop-in replacement. It retains the same 40 mm bore, 175 mm stroke, G1/4 port, and U flat-end rear cover. The primary upgrade is structural: the older MAL uses threaded front and back covers on the barrel, whereas the modern MBL features a riveted rolling-packed body for enhanced assembly integrity. Both generations rely on a fixed rubber bumper for end-of-stroke deceleration rather than an adjustable air cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL40X175U carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The B01-MBL40X175U 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.

Provides 628 N of push force at 0.5 MPa to swing a mechanical diverting gate on a 40 mm bore packaging conveyor, with the 175 mm stroke providing the full swing arc needed to reroute boxes.
Extends 175 mm to fold the rear major flap of a corrugated shipping carton before tape sealing, utilizing the rigid U flat-end rear cover to mount solidly against the machine frame.
Pushes stamped small metal parts out of a lower die bed using 880 N of thrust at 0.7 MPa, relying on the fixed rubber bumper to prevent harsh metal-on-metal impact at the end of the stroke.
To replace this discontinued cylinder, order the MBL40X175U, which matches the 40 mm bore, 175 mm stroke, PT threaded G1/4 port, and rigid U flat-end back cover. Since this specific SKU has no -S magnet, it cannot support a position sensor; if your machine requires rod detection, you must step up to an MBL40X175US and upgrade to the current CMSG, DMSG, or EMSG switch family (the older MAL used CS1-M or DS1-M sensors). The fixed rubber bumper softens impact but is not an adjustable cushion—if your application requires precise end-of-stroke deceleration, migrate to the MBLC40X175U variant on the current line.
For sizing flexibility, you can step down to the 32 mm bore (which yields 402 N push at 0.5 MPa) if your load is lighter, or step up—though 40 mm is the largest available bore in this mini round family. At 175 mm of travel, the 16 mm rod has moderate side-load tolerance; ensure your load is axially aligned or use an external guide to prevent rod binding. Note that a plain double-acting cylinder drifts when air pressure is lost, so add an external rod lock if the load must be held vertically.
Upgrade checklist
Yes, the B01-MAL40X175U is discontinued. The exact drop-in replacement is the MBL40X175U, which matches the 40 mm bore, 175 mm stroke, G1/4 port, and U flat-end cover. The "B01-" prefix simply designates an application-specific build of the standard MAL40X175U, and the MBL replacement is mechanically identical to it.
At 0.5 MPa, the 40 mm bore provides 628 N of push force and 528 N of pull force; at 0.7 MPa it provides 880 N of push, with a theoretical maximum of 128 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet code, it cannot accept a position sensor; if detection is needed, order the MBL40X175US which uses the current CMSG, DMSG, or EMSG switches.
