This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B05-MBL25X600S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B05-MBL25X600S 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 B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X600S
The AirTAC Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X600S 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 drop-in replacement is the B05-MBL25X600S, which matches its bore, stroke, force and mounting.

About the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X600S
The AirTAC B05-MAL25X600S is a discontinued double-acting aluminum mini round cylinder engineered for manipulator and pick-and-place robot arms. The B05- prefix designates it as AirTAC's robot-dedicated variant, mechanically identical to the standard MAL25X600S. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa. Because this 600 mm stroke exceeds the 500 mm standard maximum, it was produced as a non-standard, made-to-order unit. AirTAC ended the MAL line, so the exact drop-in replacement is the MBL25X600S, matching the bore, stroke, force, G1/8 port, and mounting.
This unit features a built-in magnet (-S) for position sensing. During the MAL to MBL upgrade, the body changed from threaded front and back covers to a riveted rolling-packed assembly. Consequently, the older CS1-M and DS1-M reed switches used on this MAL are replaced by the current CMSG, DMSG, or EMSG sensor families on the MBL. The piston relies on a heterogeneous two-way seal that retains grease, and the carbon-steel rod has a 20 um hard-chrome plating to resist wear during rapid robotic cycling.

Where the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X600S Is Used
Pick-and-Place Robot Arms
Drives the vertical Z-axis on Cartesian manipulators, utilizing its 245 N push force at 0.5 MPa to lift and place small electronic components across a 600 mm travel distance.
Packaging Transfer Systems
Executes long-reach pusher strokes to divert lightweight cartons between parallel conveyor belts, relying on the 30-800 mm/s speed range for rapid cycling.
Automated Storage Retrieval
Extracts tote bins from high-density shelving racks, where the 600 mm non-standard stroke provides the necessary extension depth for deep-shelf access.
Replacing the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X600S with B05-MBL25X600S
To replace the B05-MAL25X600S, order the MBL25X600S. Verify your G1/8 port, PT thread, and the magnet configuration. Since this SKU includes the -S magnet, plan to upgrade your CS1-M or DS1-M sensors to CMSG, DMSG, or EMSG switches to match the MBL body. The fixed rubber bumper on the MAL cannot be adjusted; if your robotic pick-and-place cycle requires end-of-stroke damping, step up to the current MBLC line for an adjustable air cushion.
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. At 600 mm, this non-standard stroke is highly susceptible to side-load and rod bending due to the 10 mm rod diameter. You must use an external guide rail to support the manipulator payload, as the cylinder alone cannot tolerate high lateral forces. Furthermore, a plain MAL or MBL will drift if air pressure drops, so install a pilot-operated check valve or external rod lock to hold the robot arm safely mid-stroke.
Upgrade checklist
- ✓ Order the B05-MBL25X600S (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-MBL25X600S instead of this discontinued model.
Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X600S FAQ
Yes, the MAL series is discontinued. The exact drop-in replacement is the MBL25X600S. The B05- prefix simply marks this as the robot and manipulator pick-and-place dedicated variant of the base MAL25X600S. The MBL25X600S matches the 25 mm bore, 600 mm stroke, 50 kgf max force, G1/8 port, and mounting accessories, but uses a riveted rolling-packed body instead of threaded covers.
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, with a maximum theoretical force of 50 kgf at 1.0 MPa. Because this SKU includes the -S magnet, it uses the older CS1-M and DS1-M switches. When upgrading to the MBL25X600S, you must switch to the current CMSG, DMSG, or EMSG sensor families.
