This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement B01-MBL25X600SU, 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-MAL25X600SU
The AirTAC B01-MAL Special Purpose Cylinder B01-MAL25X600SU is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 600mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the B01-MBL25X600SU, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X600SU
The AirTAC B01-MAL25X600SU 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 MAL25X600SU, meaning it is mechanically identical to the standard model but grouped for a specific customer build. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa. Because the 600 mm stroke exceeds the 500 mm standard maximum, this is a non-standard, made-to-order unit.
AirTAC replaced the entire MAL series with the MBL line, making MBL25X600SU the direct replacement. It shares the same 25 mm bore, 600 mm stroke, G1/8 port, and U flat-end back cover. The legacy MAL features a threaded front and back cover assembly, whereas the modern MBL utilizes a riveted rolling-packed body. Additionally, this SKU includes a -S magnet for position sensing; the MAL works with older CS1-M or DS1-M switches, but the MBL replacement requires the current CMSG, DMSG, or EMSG sensor families.

Where the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X600SU Is Used
PCB Conveyor Divert
Pushes populated PCB panels sideways between belt tracks over a long 600 mm travel, using the 245 N push force to slide light FR4 boards without stressing surface-mount components.
Textile Bobbin Transfer
Transfers empty yarn bobbins from a vertical storage carousel to a winding spindle, where the long stroke and compact 25 mm body fit between tight machine guarding.
Wafer Cassette Ejector
Ejects processed silicon wafer cassettes from a chemical cleaning bath station, requiring the U flat-end rigid mounting to maintain alignment over the extended 600 mm reach.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X600SU with B01-MBL25X600SU
To replace this discontinued cylinder, order the MBL25X600SU. Confirm the 25 mm bore, 600 mm made-to-order stroke, G1/8 port, and U flat-end back cover. Because this unit has a -S magnet, you must upgrade your sensing setup: the older CS1-M and DS1-M switches will not fit the MBL, so migrate to CMSG, DMSG, or EMSG sensors. If your application requires an adjustable air cushion to absorb energy at the stroke ends, note that the MAL only has a fixed rubber bumper; you should step up to the MBLC variant on the current line.
For sizing flexibility, stepping down to a 20 mm bore reduces the push force to 157 N at 0.5 MPa, while stepping up to a 32 mm bore increases it to 402 N. Because this is a 600 mm stroke on a 10 mm rod, side-load tolerance is very low. You must use an external guide rail to prevent rod bending, or switch to a double-rod MBLD configuration. Furthermore, the rubber bumper only softens end-of-stroke impacts; it does not hold the load. If air pressure drops, the rod will drift, so install an external pilot-operated check valve for position holding.
Upgrade checklist
- ✓ Order the B01-MBL25X600SU (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-MBL25X600SU instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL25X600SU FAQ
Yes, the B01-MAL25X600SU is discontinued. The direct replacement is the MBL25X600SU, which matches the 25 mm bore, 600 mm stroke, G1/8 port, and U flat-end cover. The "B01-" prefix simply designates an application-specific build of the base cylinder, so the MBL replacement fits identically. You must update your sensors, as the MBL uses CMSG, DMSG, or EMSG switches instead of the older CS1-M and DS1-M.
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. The maximum theoretical force is 50 kgf at 1.0 MPa. The 600 mm stroke exceeds the 500 mm standard maximum, making it a non-standard, made-to-order stroke. The 10 mm carbon-steel rod operates at 30-800 mm/s, but over 600 mm it requires external guidance to prevent bending.
