This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B05-MBL20X350S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B05-MBL20X350S 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-MAL20X350S
The AirTAC Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X350S is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 350mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B05-MBL20X350S, which matches its bore, stroke, force and mounting.

About the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X350S
The AirTAC B05-MAL20X350S is a discontinued compact double-acting aluminum mini round cylinder. The leading "B05-" prefix designates this as a robot or manipulator (pick-and-place) dedicated variant, though mechanically it is identical to the standard MAL20X350S. It delivers 157 N of push force and 132 N of pull force at 0.5 MPa, utilizing a G1/8 port and an 8 mm carbon-steel rod with 20 um hard-chrome plating.
Because the MAL series is end-of-life, AirTAC replaced it with the MBL20X350S. This drop-in upgrade matches the 20 mm bore, 350 mm stroke, output force, port size, and magnet configuration exactly. The original MAL features threaded front and back covers, whereas the newer MBL uses a riveted rolling-packed body. Additionally, the -S magnet on this legacy cylinder operates with older CS1-M or DS1-M switches, while the MBL replacement requires the current CMSG, DMSG, or EMSG sensor families.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B05-MBL20X350S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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-MAL20X350S Is Used
Pick-and-Place Z-Axis
Extends 350 mm to lower a suction cup gripper from an overhead manipulator rail to a conveyor belt, relying on the 157 N push force at 0.5 MPa to lift small plastic housings.
PCB Shuttle Extraction
Pushes a finished circuit board out of a wave soldering fixture, using the built-in magnet and a CS1-M switch to confirm full extension before the robotic arm retracts.
Carton Flap Tucking
Reaches 350 mm into a packaging cell to tuck inner flaps on small shipping boxes, where the compact 20 mm aluminum body fits neatly between adjacent folding rails.
Replacing the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X350S with B05-MBL20X350S
To replace this discontinued manipulator cylinder, order the MBL20X350S, which offers identical 350 mm stroke, G1/8 port, PT thread, and magnet options. If your pick-and-place payload is lighter, stepping down to a MAL/MBL 16 bore is not an option since 20 mm is the smallest available size. If you need more grip force, stepping up to the 25 mm bore yields 245 N push at 0.5 MPa. Note that a plain cylinder drifts when air is lost; the fixed rubber bumper only softens end-of-stroke impact and does not lock the load, so add an external rod lock for vertical holding.
With a 350 mm stroke on an 8 mm rod, side-load tolerance is minimal. To prevent rod bending in a robotic arm, use an external guide rail or ensure the pivot bracket allows self-alignment. If end-of-stroke impact becomes an issue, the current-line MBLC offers an adjustable air cushion that the MAL lacks.
Upgrade checklist
- ✓ Order the B05-MBL20X350S (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-MBL20X350S instead of this discontinued model.
Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X350S FAQ
Yes, the MAL series is discontinued. The exact drop-in replacement is the MBL20X350S. It matches the 20 mm bore, 350 mm stroke, G1/8 port, and magnet configuration. The "B05-" prefix simply marked this as a pick-and-place robot variant, and the newer MBL features a riveted body instead of threaded covers. You will also need to upgrade your sensors, as the MBL uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M.
At 0.5 MPa, the push force is 157 N and the pull force is 132 N. At 0.7 MPa, the push force increases to 220 N. The maximum theoretical force is 32 kgf at 1.0 MPa. Remember this cylinder uses a fixed rubber bumper, not an adjustable cushion.
