This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B05-MBL40X300 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B05-MBL40X300 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-MAL40X300
The AirTAC Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL40X300 is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 300mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B05-MBL40X300, which matches its bore, stroke, force and mounting.

About the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL40X300
The AirTAC B05-MAL40X300 is a discontinued double-acting aluminum mini round cylinder. The B05- prefix marks it as a robot and manipulator pick-and-place dedicated variant, though mechanically it is identical to the standard MAL40X300. It delivers 628 N push and 528 N pull force at 0.5 MPa, utilizing a 16 mm carbon-steel rod with 20 um hard chrome plating. AirTAC replaced this legacy unit with the MBL40X300, a drop-in alternative retaining the exact 40 mm bore, 300 mm stroke, G1/4 port, and 128 kgf maximum force.
Unlike the threaded front and back covers found on this MAL body, the current MBL replacement features a riveted rolling-packed barrel for structural rigidity. Because this specific SKU lacks the -S magnet code, it cannot accept position sensors. Additionally, end-of-stroke energy relies solely on a fixed rubber bumper, whereas the modern MBLC line introduces an adjustable air cushion absent from the original MAL design.

Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |

Where the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL40X300 Is Used
Pick-and-Place Robot Arms
Drives the 300 mm Z-axis stroke on manipulators transferring components between conveyor belts, utilizing the 628 N push force to lift rigid parts securely.
PCB Handling Lines
Actuates 300 mm routing gates in electronics assembly, where the compact aluminum body fits tight machine frames and the fixed rubber bumper absorbs end-of-stroke impact.
Packaging Diverters
Pushes cartons from a main packaging track to a secondary lane, leveraging the G1/4 port for rapid 30-800 mm/s cycling without requiring a position sensor.
Replacing the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL40X300 with B05-MBL40X300
To replace the B05-MAL40X300, order the MBL40X300. Confirm your 40 mm bore, 300 mm stroke, G1/4 port, and default PT tapered thread. This SKU has no -S magnet, so no position sensing is possible; if your manipulator requires end-of-stroke feedback, step up to an MBL model with the -S code, which also transitions the switches from the legacy CS1-M / DS1-M to the current CMSG / DMSG / EMSG family. If sizing down, the 32 mm bore yields 402 N push at 0.5 MPa; if stepping up, note that 40 mm is the largest MAL mini round bore available. The 300 mm stroke on a 16 mm rod demands careful side-load management—use an external guide rail or an SDB pivot bracket to prevent rod bending. A plain bumper does not hold position upon air loss, so deploy an external rod lock for vertical loads. For heavier kinetic energy, consider the MBLC for its adjustable cushion.
Upgrade checklist
- ✓ Order the B05-MBL40X300 (same bore/stroke/force)
- ✓ Same G1/4 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-MBL40X300 instead of this discontinued model.
Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL40X300 FAQ
Yes, the B05-MAL40X300 is discontinued. The exact drop-in replacement is the MBL40X300, which matches the 40 mm bore, 300 mm stroke, G1/4 port, and mounting dimensions. The B05- prefix simply designated it for robot and manipulator pick-and-place use, and the MBL replacement is mechanically identical.
At 0.5 MPa it provides 628 N push and 528 N pull; at 0.7 MPa push is 880 N, with a maximum theoretical force of 128 kgf at 1.0 MPa. This specific SKU lacks a magnet, so it cannot accept CS1-M or DS1-M sensors. If you need position detection, order the MBL40X300S, which uses the newer CMSG / DMSG / EMSG switches.
