This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B05-MBL25X800 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B05-MBL25X800 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-MAL25X800
The AirTAC Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X800 is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 800mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B05-MBL25X800, which matches its bore, stroke, force and mounting.

About the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X800
The AirTAC B05-MAL25X800 is a discontinued double-acting aluminum mini round cylinder engineered for long-reach robotic manipulator and pick-and-place tasks. The "B05-" prefix marks this as AirTAC's manipulator-dedicated variant, mechanically identical to the standard MAL25X800. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa. Because this legacy series is end-of-life, AirTAC replaced it with the MBL25X800—a drop-in alternative retaining the exact 25 mm bore, 800 mm stroke, G1/8 port, and 50 kgf maximum thrust.
This 800 mm stroke is a non-standard, made-to-order length that exceeds the 500 mm standard maximum. The original MAL body relies on threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body. This SKU lacks a -S magnet, meaning it cannot support position sensing. Furthermore, the fixed rubber bumper only softens end-of-stroke impacts; it cannot hold a load if air pressure drops, requiring an external rod lock for vertical manipulation.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B05-MBL25X800 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | — |

Where the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X800 Is Used
Pick-and-Place Robot Arms
Drives the extended 800 mm horizontal reach on Cartesian manipulators transferring electronic components between conveyor belts, utilizing the 245 N push force at 0.5 MPa to maintain pace without overstressing the arm.
Long-Reach Carton Pushing
Ejects lightweight packaged goods from the far side of a packaging cell where a standard 500 mm stroke falls short, relying on the aluminum body to keep the robot end-effector payload low.
Palletizer Diverter
Actuates a sweeping diverter arm across a wide 800 mm sorting conveyor to route small plastic bottles, requiring an external guide to prevent the 10 mm rod from binding under lateral acceleration.
Replacing the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X800 with B05-MBL25X800
To replace this discontinued manipulator cylinder, order the MBL25X800. Confirm your G1/8 port, PT thread, and 800 mm non-standard stroke requirement with the factory. If your pick-and-place cycle requires end-of-stroke cushioning, the fixed rubber bumper on this MAL cannot be adjusted—you should step up to the current MBLC25X800, which offers an adjustable air cushion. If you need to downsize the manipulator arm to reduce weight, the 20 mm bore neighbor provides 157 N of push force at 0.5 MPa. If the 25 mm rod lacks the rigidity needed for a heavier end-effector, stepping up to the 32 mm bore yields 402 N of push force at 0.5 MPa.
Because the 800 mm stroke is exceptionally long for a 10 mm rod, side-load tolerance is minimal. To prevent rod bending and premature seal wear during robotic sweeping motions, you must use an external guide rail or a pivot mounting accessory. Note that a plain MAL/MBL cylinder will drift if air is lost; the bumper is not a locking mechanism.
Upgrade checklist
- ✓ Order the B05-MBL25X800 (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-MBL25X800 instead of this discontinued model.
Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X800 FAQ
Yes, the B05-MAL25X800 (the manipulator-dedicated variant of the MAL25X800) is discontinued. The exact drop-in replacement is the MBL25X800, which matches the 25 mm bore, 800 mm stroke, G1/8 port, and mounting dimensions. The modern MBL uses a riveted rolling-packed body instead of the older threaded covers, but all performance ratings remain identical.
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, and the maximum theoretical force is 50 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet option, it cannot accept CS1-M or DS1-M position sensors; if your manipulator requires end-of-stroke detection, you must order the MBL25X800S and use the current CMSG or DMSG switch family.
