This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL32X25SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL32X25SU 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-MAL32X25SU
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL32X25SU is a double-acting aluminum-barrel mini round cylinder with a Ø32mm bore and 25mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL32X25SU, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL32X25SU
The AirTAC B01-MAL32X25SU is a discontinued compact double-acting aluminum mini round cylinder. The leading "B01-" prefix marks this as an application-dedicated (customer-specified) variant of the base MAL32X25SU, meaning it is mechanically identical to the standard line but grouped for a specific dedicated build. Delivering 402 N of push force at 0.5 MPa, it is replaced directly by the MBL32X25SU.
The MBL32X25SU is a drop-in replacement retaining the exact 32 mm bore, 25 mm stroke, G1/8 port, and flat-end U cover. A key upgrade is the body construction: the legacy MAL uses threaded front and back covers, whereas the current MBL features a riveted rolling-packed body. Because this SKU includes the -S magnet, note that the older CS1-M / DS1-M switches used on the MAL must be upgraded to the current CMSG / DMSG / EMSG sensor family on the MBL.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL32X25SU carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The B01-MBL32X25SU 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-MAL32X25SU Is Used
PCB Depaneling Router
Provides the 402 N push at 0.5 MPa needed to clamp populated circuit boards firmly into a routing fixture before the spindle separates the panels.
Carton Flap Folder
Uses the short 25 mm stroke to rapidly tuck minor flaps on small packaging lines, relying on the rigid U flat-end cover to maintain alignment under high cycle counts.
Connector Insertion Press
Drives a 12 mm rod with 563 N of thrust at 0.7 MPa to seat pin headers into plastic housings without damaging the delicate molded receptacles.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL32X25SU with B01-MBL32X25SU
To replace this discontinued cylinder, order the MBL32X25SU. Confirm the 32 mm bore, 25 mm stroke, G1/8 port, PT thread, and the flat-end U back cover. Because this SKU has the -S magnet, you must also switch from the legacy CS1-M / DS1-M sensors to the CMSG / DMSG / EMSG switches on the new MBL. The fixed rubber bumper carries over, but if your application now requires adjustable end-cushioning, step up to the MBLC variant on the current line.
When sizing, you can step down to the 25 mm bore (delivering 245 N push at 0.5 MPa) for lighter loads, or step up to the 40 mm bore (628 N push at 0.5 MPa) if you need more force. Note that the plain rubber bumper is not a lock; a standard MAL or MBL will drift and cannot hold a load if air pressure is lost, so add an external rod lock for vertical or gravity-loaded applications.
Upgrade checklist
- ✓ Order the B01-MBL32X25SU (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-MBL32X25SU instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL32X25SU FAQ
Yes, the B01-MAL32X25SU is discontinued. The exact drop-in replacement is the MBL32X25SU, which matches the 32 mm bore, 25 mm stroke, G1/8 port, and U flat-end cover. The "B01-" prefix simply designated an application-specific build of the standard MAL32X25SU, so the MBL replaces it perfectly. You must upgrade any -S magnet sensors from the old CS1-M / DS1-M to the new CMSG / DMSG / EMSG family.
At 0.5 MPa, the 32 mm bore provides 402 N of push force and 346 N of pull force. At 0.7 MPa, the push force increases to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa. It uses a fixed rubber bumper, not an adjustable cushion.
