This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement B01-MBL25X100U, 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).
Airtac B01-MAL Special Purpose Cylinder B01-MAL25X100U
The AirTAC B01-MAL Special Purpose Cylinder B01-MAL25X100U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 100mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the B01-MBL25X100U, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X100U
The AirTAC B01-MAL25X100U is a discontinued compact double-acting aluminum mini round cylinder. The leading "B01-" prefix designates this as an application-dedicated (customer-specified) variant of the base MAL25X100U, meaning it shares the exact same 25 mm bore, 100 mm stroke, and mechanical specs. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa. AirTAC replaced the entire MAL series with the MBL line, making the MBL25X100U the direct replacement.
This legacy cylinder features a threaded front and back cover design, whereas the current MBL uses a riveted rolling-packed body. Because this specific SKU lacks the -S magnet option, it cannot accept a position sensor. The internal piston relies on a heterogeneous two-way seal that retains grease, and the carbon-steel rod has a 20 um hard-chrome plating to resist wear. End-of-stroke deceleration is handled by a fixed rubber bumper, not an adjustable air cushion.

Where the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X100U Is Used
PCB Depaneling Router
Pushes a fixture to clamp individual circuit boards during the routing and depaneling process, utilizing the 245 N push force to prevent board vibration.
Carton Flap Folder
Actuates a mechanical arm to fold minor flaps on small packaging cartons, where the 100 mm stroke provides the precise travel needed for compact box widths.
Connector Insertion Press
Drives a small pneumatic press to seat pin headers into electronic connectors, relying on the rigid U flat-end back cover to maintain alignment under 206 N of pull force.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X100U with B01-MBL25X100U
To replace this discontinued cylinder, order the MBL25X100U. It matches the 25 mm bore, 100 mm stroke, G1/8 port, PT thread, and U flat-end back cover. Since this SKU has no -S magnet, it cannot support a sensor; if you need position detection on the new unit, add the -S option to the MBL and note that the sensor family changes from the older CS1-M / DS1-M to the current CMSG / DMSG / EMSG switches.
For sizing, this 25 mm bore provides 245 N push at 0.5 MPa. If you need less force, step down to the 20 mm bore (157 N push). If your application requires more power, step up to the 32 mm bore (402 N push). The fixed rubber bumper is not a lock; if you need to hold a vertical load without drifting when air pressure drops, install an external rod lock or pilot-operated check valve. If you require adjustable end-cushioning for heavier loads, look at the MBLC variant on the current line.
Upgrade checklist
- ✓ Order the B01-MBL25X100U (same bore/stroke/force)
- ✓ Same G1/8 port and mounting accessories
- ✓ Sensor: swap CS1-M/DS1-M → CMSG/DMSG/EMSG
- ✓ Need a cushion? use MBLC (adjustable air cushion)
- ✓ Confirm back cover (CA / U) and thread (PT/NPT/G)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.1 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Front/rear covers are threaded — not intended for field disassembly.
- check Use the correct mounting accessory (LB / FA / SDB) and back cover (CA / U / CM).
- check For new builds, specify the B01-MBL25X100U instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL25X100U FAQ
Yes, the AirTAC B01-MAL25X100U is discontinued. The direct replacement is the MBL25X100U. The "B01-" prefix simply marks this as an application-dedicated variant of the MAL25X100U, so the MBL replacement offers identical bore, stroke, force, and port size. 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 push force is 245 N and the pull force is 206 N. 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 does not have the -S magnet, it cannot accept a position sensor. If you order the MBL replacement with a magnet (-S), you must use the current CMSG, DMSG, or EMSG switches instead of the older CS1-M or DS1-M sensors.
