This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B05-MBL20X300S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B05-MBL20X300S 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).

The AirTAC Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X300S is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 300mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B05-MBL20X300S, which matches its bore, stroke, force and mounting.
The AirTAC B05-MAL20X300S is a discontinued double-acting aluminum mini round cylinder. The B05- prefix designates it as a robot and manipulator pick-and-place dedicated variant, mechanically identical to the standard MAL20X300S. It delivers 157 N of push force and 132 N of pull force at 0.5 MPa. AirTAC has ended this series, making the MBL20X300S the exact drop-in replacement. It matches the original 20 mm bore, 300 mm stroke, G1/8 port, and M8x1.25 rod thread.
Upgrading to the MBL swaps the legacy threaded end covers for a riveted rolling-packed body while retaining the exact force ratings. This SKU includes a magnet (-S) for position detection; the older MAL works with CS1-M / DS1-M switches, but the MBL replacement transitions to the current CMSG / DMSG / EMSG sensor family. The 8 mm carbon-steel rod has a 20 um hard chrome plating and relies on a self-lubricating front-cover bearing guide. End-of-stroke deceleration is handled by a fixed rubber bumper, not an adjustable cushion.

| 0.7 MPa | 220 N | — |
| Max (@1.0 MPa) | 32 kgf | |
The B05-MBL20X300S produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

Replacement mapping: MAL → MBL, MSAL → MSBL, MTAL → MTBL, MALD → MBLD, MALJ → MBLJ.
Drives the Z-axis extension on manipulators transferring electronic components, utilizing the 300 mm stroke to reach into shallow trays.
Pushes defective printed circuit boards off a high-speed conveyor line using 157 N of push force at 0.5 MPa.
Actuates a diverting gate in packaging machinery to route small plastic housings into secondary bins.
To replace this discontinued cylinder, order the MBL20X300S. Verify your 300 mm stroke, G1/8 port, and PT thread form. Because this SKU has the -S magnet, you must update your sensing to CMSG / DMSG / EMSG switches, as the legacy CS1-M / DS1-M sensors are incompatible with the MBL body. If your pick-and-place payload requires less force, step down to a 16 mm bore (confirm from datasheet for force); if you need more power, step up to the 25 mm bore, which provides 245 N of push force at 0.5 MPa. A plain cylinder does not hold position if air pressure drops; add an external rod lock for vertical payloads. If end-of-stroke bouncing is an issue, specify the MBLC for adjustable air cushions. At 300 mm of travel on an 8 mm rod, side-load tolerance is low; use an external guide rail or a pivot mount to prevent rod bending.
Upgrade checklist
Yes, the B05-MAL20X300S is discontinued. The exact drop-in replacement is the MBL20X300S. The B05- prefix simply marked it as a pick-and-place robot dedicated variant of the MAL20X300S; the MBL matches its 20 mm bore, 300 mm stroke, G1/8 port, and mounting dimensions exactly.
At 0.5 MPa it provides 157 N push and 132 N pull; at 0.7 MPa it provides 220 N push, with a theoretical maximum of 32 kgf at 1.0 MPa. Because this SKU includes a magnet (-S), it accepts sensors; the MAL uses CS1-M / DS1-M switches, but the MBL20X300S replacement requires CMSG / DMSG / EMSG switches.
