This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL25X500U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL25X500U 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).
Airtac B01-MAL Special Purpose Cylinder B01-MAL25X500U
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL25X500U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 500mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL25X500U, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X500U
The AirTAC B01-MAL25X500U is a discontinued double-acting aluminum mini round cylinder. The B01- prefix designates this as an application-dedicated, customer-specified variant of the standard MAL25X500U, meaning it shares the exact same 25mm bore, 500mm stroke, and mechanical specifications. Generating 245 N of push force at 0.5 MPa, it is replaced directly by the MBL25X500U. This current MBL model serves as a drop-in substitute, matching the bore, stroke, output force, G1/8 port, and U flat-end back cover exactly.
Two key engineering details distinguish the legacy design from its replacement. The original MAL features threaded front and back covers, whereas the modern MBL utilizes a riveted rolling-packed body for a more rigid assembly. Additionally, because this specific SKU lacks an S designation, it has no internal magnet and cannot support position sensing; if detection is needed on the new MBL, you must order an -S version which uses the current CMSG, DMSG, or EMSG switch families instead of the older CS1-M/DS1-M sensors.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL25X500U carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | — |
| Max (@1.0 MPa) | 50 kgf | |
The B01-MBL25X500U 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.

Where the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X500U Is Used
PCB Conveyor Routing
Pushes printed circuit boards across a 500mm transfer gap between inline SMT machines, using the 245N push force to overcome edge guide friction.
Carton Flap Folding
Extends 500mm to fold large corrugated box flaps prior to tape sealing, where the compact 25mm bore fits tightly beside the packaging frame.
Textile Yarn Doffing
Traverses 500mm to push full yarn bobbins off a spinning spindle, relying on the self-lubricating front-cover bearing guide to handle repetitive high-speed cycles.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X500U with B01-MBL25X500U
To replace this cylinder, order the MBL25X500U. Verify your 500mm stroke requirement, the G1/8 port, the PT thread form, and the U flat-end back cover. Because this legacy unit lacks a magnet, it cannot accept a sensor; if your updated application requires position detection, step up to an MBL25X500US and use a CMSG or DMSG switch. If you need to adjust the bore size, stepping down to a 20mm bore yields 157 N of push force at 0.5 MPa, while stepping up to a 32mm bore provides 402 N.
At 500mm of stroke, the 10mm rod is highly susceptible to bending under lateral stress. Use an external guide rail to support the load, or switch to a CA pivot or SDB mounting bracket to absorb angular misalignment. Remember that the fixed rubber bumper softens end-of-stroke impacts but is not an adjustable air cushion; for deceleration control on the current line, specify the MBLC variant. Furthermore, this cylinder will not hold a load if air pressure drops—install an external rod lock for vertical applications.
Upgrade checklist
- ✓ Order the B01-MBL25X500U (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-MBL25X500U instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL25X500U FAQ
Yes, the B01-MAL25X500U is discontinued. The exact drop-in replacement is the MBL25X500U, which matches the 25mm bore, 500mm stroke, G1/8 port, and U flat-end cover. The B01- prefix simply marked this as an application-dedicated variant of the base MAL25X500U, so the MBL replacement is mechanically identical to your legacy unit.
At 0.5 MPa it provides 245 N push and 206 N pull force; at 0.7 MPa it provides 343 N push, with a maximum theoretical force of 50 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet code, it cannot accept a position sensor. If you need detection on the replacement MBL, you must order the -S version and use CMSG, DMSG, or EMSG switches.
