This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement B05-MBL20X50, 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-MAL20X50
The AirTAC Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X50 is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 50mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the B05-MBL20X50, which matches its bore, stroke, force and mounting.

About the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X50
The AirTAC B05-MAL20X50 is a discontinued compact double-acting aluminum mini round cylinder. The leading "B05-" prefix marks this as AirTAC's robot or manipulator dedicated variant, engineered for light pick-and-place tasks. Mechanically, it is identical to the base MAL20X50, delivering 157 N of push force and 132 N of pull force at 0.5 MPa. Because the MAL series is end-of-life, the direct replacement is the MBL20X50, which matches the 20 mm bore, 50 mm stroke, G1/8 port, and mounting footprint.
Upgrading to the MBL changes the body assembly from threaded front and back covers to a riveted rolling-packed barrel, maintaining the same physical ratings. This B05-MAL20X50 SKU lacks a built-in magnet, meaning it cannot accept a position sensor. The internal piston relies on a heterogeneous two-way seal that retains grease, while the 8 mm carbon-steel rod features 20 um hard-chrome plating to resist wear during rapid manipulator cycles.

Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | — |

Where the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X50 Is Used
Pick-and-Place Robot Arms
Drives the short 50 mm extend motion on Cartesian manipulators transferring small electronic components between conveyor belts.
PCB Board Handling
Pushes a lightweight suction cup array down onto printed circuit boards, using the 157 N push force to seat flat flex cables.
Small Parts Ejection
Ejects plastic injection-molded caps from a tight mold cavity, relying on the compact 20 mm body to fit within the press frame.
Replacing the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X50 with B05-MBL20X50
To replace the B05-MAL20X50, order the MBL20X50. Confirm your 50 mm stroke, G1/8 port, and PT thread form. Since this SKU has no magnet, you cannot mount a sensor; if you need position detection on the new unit, order an MBL20X50S and note that the switch family changes from the legacy CS1-M / DS1-M to the current CMSG / DMSG / EMSG series. The fixed rubber bumper softens end-of-stroke impacts, but if your pick-and-place cycle requires adjustable cushioning, step up to the MBLC20X50 on the current line.
For sizing, the 20 mm bore provides 157 N push at 0.5 MPa. If your end-effector payload is lighter, stepping down to the 12 mm bore class yields less force, while moving up to the 25 mm bore provides 245 N push at 0.5 MPa for heavier grippers. A plain cylinder does not hold its load when air pressure drops; the rod will drift. Use an external rod lock or pilot-operated check valve if your manipulator arm must maintain vertical position during an air loss event.
Upgrade checklist
- ✓ Order the B05-MBL20X50 (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-MBL20X50 instead of this discontinued model.
Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X50 FAQ
Yes, the B05-MAL20X50 is discontinued. The direct replacement is the MBL20X50. It offers the same 20 mm bore, 50 mm stroke, G1/8 port, and mounting dimensions. The B05- prefix simply indicated the robot or manipulator dedicated variant, and the MBL replacement fits those same pick-and-place applications.
At 0.5 MPa it provides 157 N push and 132 N pull; at 0.7 MPa it provides 220 N push; the maximum theoretical force is 32 kgf at 1.0 MPa. This specific SKU lacks the -S magnet, so it cannot accept a position sensor. If you need detection, order the MBL20X50S and use CMSG, DMSG, or EMSG switches.
