This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL40X25SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL40X25SU 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-MAL40X25SU
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL40X25SU is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 25mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL40X25SU, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X25SU
The AirTAC B01-MAL40X25SU is a discontinued double-acting aluminum mini round cylinder. The leading "B01-" prefix marks this as an application-dedicated (customer-specified) variant; mechanically, it is identical to the standard MAL40X25SU, delivering 628 N of push force and 528 N of pull force at 0.5 MPa. Because the MAL series is end-of-life, you should order the exact drop-in replacement: the MBL40X25SU. It matches the 40 mm bore, 25 mm stroke, G1/4 port, and U flat-end back cover perfectly.
This cylinder features a fixed rubber bumper for end-of-stroke damping and a heterogeneous two-way seal that retains grease for long service life. The original MAL body uses threaded front and back covers, whereas the newer MBL replacement utilizes a riveted rolling-packed body. Additionally, this SKU includes a -S magnet for position sensing; on the legacy MAL, this requires the older CS1-M or DS1-M switches, but the MBL replacement upgrades you to the current CMSG, DMSG, or EMSG sensor family.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL40X25SU carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The B01-MBL40X25SU 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-MAL40X25SU Is Used
Injection Mold Ejection
Drives short-stroke ejector pins in compact plastic injection molding machines, using the 628 N push force at 0.5 MPa to break parts free from the mold cavity.
Bottle Diverting Gate
Actuates a rigid diverting gate on a 40 mm packaging line conveyor, relying on the U flat-end cover to hold alignment during high-speed product routing.
PCB Test Fixture Clamping
Secures printed circuit boards in an automated test fixture, using the -S magnet and CS1-M sensors to confirm the 25 mm clamp stroke is fully engaged before testing begins.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X25SU with B01-MBL40X25SU
To replace this discontinued cylinder, order the MBL40X25SU. Verify your 40 mm bore, 25 mm stroke, G1/4 port, PT thread, and the U flat-end back cover. Because this SKU includes the -S magnet, note that your old CS1-M / DS1-M switches will not fit the MBL; you must upgrade to CMSG, DMSG, or EMSG sensors. If you need adjustable air cushioning instead of the fixed rubber bumper, step up to the MBLC variant on the current line. A plain MAL or MBL does not hold its position when air is lost—the rod will drift—so add an external rod lock for suspended loads.
When sizing, check the neighboring bores to ensure this is the right force class. Stepping down to a 32 mm bore drops the 0.5 MPa push force to 402 N, while stepping up is not an option in this mini series, as 40 mm is the largest available MAL/MBL size. The 16 mm carbon-steel rod handles high axial loads well, but if your application introduces arcing side-loads, consider switching the rigid U flat-end cover for a CA pivot or SDB pivot bracket.
Upgrade checklist
- ✓ Order the B01-MBL40X25SU (same bore/stroke/force)
- ✓ Same G1/4 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-MBL40X25SU instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL40X25SU FAQ
Yes, the MAL series is discontinued. The exact drop-in replacement is the MBL40X25SU. The "B01-" prefix simply designates an application-specific build; mechanically, it is identical to the base MAL40X25SU. The MBL replacement shares the same 40 mm bore, 25 mm stroke, G1/4 port, and U flat-end cover, but uses a riveted body instead of threaded covers.
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force is 880 N, with a maximum theoretical force of 128 kgf at 1.0 MPa. This SKU includes a -S magnet for position detection; legacy MAL cylinders use CS1-M or DS1-M switches, but the MBL40X25SU replacement requires the newer CMSG, DMSG, or EMSG sensor family.
