This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement B05-MBL25X900S, 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 B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X900S
The AirTAC B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X900S is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 900mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the B05-MBL25X900S, which matches its bore, stroke, force and mounting.

About the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X900S
The AirTAC B05-MAL25X900S is a discontinued double-acting aluminum mini round cylinder. The "B05-" prefix designates it as a robot and manipulator pick-and-place dedicated variant, though it is mechanically identical to the standard MAL25X900S. Delivering 245 N push and 206 N pull at 0.5 MPa, this unit features a 900 mm stroke that exceeds the 500 mm standard limit, making it a non-standard, made-to-order actuator. AirTAC replaced the entire MAL line with the MBL series; the direct replacement is the MBL25X900S, matching the 25 mm bore, G1/8 port, 10 mm rod, and force ratings.
This model includes a built-in magnet (-S) for position detection. On the legacy MAL body—which uses threaded front and back covers—the magnet pairs with older CS1-M or DS1-M reed switches. The modern MBL25X900S features a riveted rolling-packed body and requires the current CMSG, DMSG, or EMSG sensor families. Both generations rely on a fixed rubber bumper for end-of-stroke damping rather than an adjustable air cushion. The piston uses a heterogeneous two-way seal that retains grease, running against a carbon-steel rod with 20 um hard-chrome plating.

Where the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X900S Is Used
SCARA Robot Z-Axis Extension
Utilizes the 900 mm stroke to lower a 25 mm bore gripper deep into a machine tool enclosure for part extraction, relying on the 245 N push force to overcome spindle suction.
Carton Flap Folder
Extends across a wide packaging line to tuck long cardboard flaps, where the 206 N pull force reliably retracts the 10 mm rod against sticky adhesive residue.
PCB Panel Pusher
Transfers large printed circuit boards between conveyor belts in an SMT line, requiring the -S magnet and CS1-M / DS1-M switches to verify full extension at 900 mm.
Replacing the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X900S with B05-MBL25X900S
To replace the B05-MAL25X900S, order the MBL25X900S. It is a direct upgrade retaining the 25 mm bore, 900 mm non-standard stroke, G1/8 port, PT thread, and magnet. Because your MAL has the -S magnet, you must upgrade your sensors: the older CS1-M / DS1-M switches will not fit the MBL body, so migrate to CMSG / DMSG / EMSG switches. If your pick-and-place cycle requires adjustable end-cushioning to stop heavy loads smoothly, step up to the MBLC variant on the current line, as the MAL only offers a fixed rubber bumper.
For sizing flexibility, stepping down to a 20 mm bore yields 157 N push at 0.5 MPa, while stepping up to a 32 mm bore provides 402 N push. At 900 mm of stroke, the 10 mm rod is highly susceptible to bending under side-loads; a plain cylinder does not hold its load if air pressure drops. You must use an external guide rail to support the manipulator payload, or pivot the cylinder with a CA or SDB mounting bracket to absorb angular motion.
Upgrade checklist
- ✓ Order the B05-MBL25X900S (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 B05-MBL25X900S instead of this discontinued model.
Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X900S FAQ
Yes, the B05-MAL25X900S is discontinued. The direct replacement is the MBL25X900S. The "B05-" prefix simply marked it as a manipulator pick-and-place variant; mechanically it is identical to the base MAL25X900S. The MBL replacement matches the 25 mm bore, 900 mm stroke, G1/8 port, and force ratings, but uses a riveted body instead of threaded covers.
At 0.5 MPa, the 25 mm bore provides 245 N push and 206 N pull. At 0.7 MPa, push increases to 343 N, with a maximum theoretical force of 50 kgf at 1.0 MPa. Because this SKU includes a magnet (-S), it works with older CS1-M / DS1-M switches on the MAL. If you upgrade to the MBL25X900S, you must switch to CMSG, DMSG, or EMSG sensors.
