This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement B05-MBL32X20, 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-MAL32X20
The AirTAC Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL32X20 is a double-acting aluminum-barrel mini round cylinder with a Ø32mm bore and 20mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the B05-MBL32X20, which matches its bore, stroke, force and mounting.

About the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL32X20
The AirTAC B05-MAL32X20 is a discontinued compact double-acting aluminum mini round cylinder engineered for manipulator and pick-and-place robot arms. The B05- prefix designates this as a robot-dedicated variant, mechanically identical to the standard MAL32X20, delivering 402 N of push force at 0.5 MPa. Because the MAL series is end-of-life, AirTAC now supplies the MBL32X20 as the direct replacement, matching the 32 mm bore, 20 mm stroke, G1/8 port, and PT thread.
This short-stroke actuator relies on a fixed rubber bumper to soften end-of-stroke impacts, meaning it lacks adjustable cushioning. The legacy MAL body features threaded front and back covers, whereas the modern MBL replacement utilizes a riveted rolling-packed body for equally robust performance. Since this specific SKU lacks a magnet (-S), it cannot accept position sensors; additionally, a plain cylinder cannot hold a load if air pressure drops, requiring an external rod lock for vertical manipulation safety.

Where the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL32X20 Is Used
Pick-and-Place Robot Arms
Drives the short 20 mm extraction motion on Cartesian manipulators, utilizing its 402 N push force to lift and transfer small electronic components between testing trays.
Palletizer Diverter Gates
Actuates lightweight routing flaps on packaging conveyors where the compact 32 mm body fits within tight side-frame clearances to redirect small cartons.
PCB Board Ejectors
Provides the precise 20 mm ejection stroke to push finished printed circuit boards out of assembly fixtures without damaging delicate solder joints.
Replacing the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL32X20 with B05-MBL32X20
To replace the discontinued B05-MAL32X20, order the MBL32X20, ensuring you retain the standard PT tapered port thread and G1/8 port size. If your pick-and-place cycle requires end-of-stroke cushioning adjustment, step up to the MBLC32X20 on the current line, as the MAL only offers a fixed rubber bumper. If sizing force for a lighter payload, step down to the 25 mm bore (MBL25X20) which provides 245 N push at 0.5 MPa; for heavier gripper loads, step up to the 40 mm bore (MBL40X20) yielding 628 N push at 0.5 MPa. Remember that without air pressure, this cylinder will drift and cannot hold a suspended manipulator load.
Upgrade checklist
- ✓ Order the B05-MBL32X20 (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-MBL32X20 instead of this discontinued model.
Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL32X20 FAQ
Yes, the B05-MAL32X20 is discontinued. The direct replacement is the MBL32X20, which shares the same 32 mm bore, 20 mm stroke, G1/8 port, and PT thread. The B05- prefix simply marks it as a manipulator-dedicated variant, and the MBL32X20 fits the same mounting footprint.
At 0.5 MPa it provides 402 N push and 346 N pull force; at 0.7 MPa it provides 563 N push, with a maximum theoretical force of 82 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept CS1-M or DS1-M position sensors; if sensing is needed, order the MBL32X20S which uses the modern CMSG/DMSG/EMSG switches.
