This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement B05-MBL20X150S, 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-MAL20X150S
The AirTAC B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X150S is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 150mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the B05-MBL20X150S, which matches its bore, stroke, force and mounting.

About the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X150S
The AirTAC B05-MAL20X150S is a discontinued compact double-acting aluminum mini round cylinder. The "B05-" prefix designates it as a robot and manipulator (pick-and-place) dedicated variant, though mechanically it is identical to the base MAL20X150S. Delivering 157 N of push force at 0.5 MPa over a 150 mm stroke, it is now replaced by the direct replacement MBL20X150S, which shares the exact same bore, port, and mounting dimensions.
This legacy model features a threaded front and back cover assembly, whereas the current MBL upgrade utilizes a riveted rolling-packed body for streamlined assembly. The included -S magnet on this unit pairs with older CS1-M or DS1-M reed switches; if upgrading to the MBL, you must transition to the current CMSG, DMSG, or EMSG sensor families. The bore uses a self-lubricating front-cover bearing guide and a heterogeneous two-way seal to retain grease, while the 8 mm carbon-steel rod features 20 um hard-chrome plating to resist wear during rapid robotic cycling.

Where the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X150S Is Used
Pick-and-Place Robot Arms
Drives the vertical Z-axis on Cartesian manipulators for moving small electronic components, utilizing the 157 N push force and 150 mm stroke to clear workspace boundaries.
PCB Board Handling
Extends to push raw printed circuit boards into testing fixtures, where the self-lubricating bearing guide maintains smooth operation across thousands of rapid cycles.
Small Parts Ejection
Pushes lightweight plastic housings out of molding machines into collection bins, relying on the fixed rubber bumper to soften the end-of-stroke impact.
Replacing the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X150S with B05-MBL20X150S
To replace this discontinued unit, order the MBL20X150S. It drops in directly with the same 20 mm bore, 150 mm stroke, G1/8 port, and PT thread. Because this SKU includes the -S magnet, you must update your inventory to CMSG, DMSG, or EMSG switches, as the older CS1-M and DS1-M sensors are incompatible with the new body. If you need adjustable end-cushioning to protect robotic payloads, step up to the MBLC variant, as the MAL only provides a fixed rubber bumper.
For sizing flexibility, stepping down to the 12 mm bore class (if available in your series) reduces force, while stepping up to the 25 mm bore yields 245 N push at 0.5 MPa for heavier end-effectors. Note that a plain MAL or MBL does not hold position when air is lost; the rod will drift. At 150 mm of stroke, the 8 mm rod has low side-load tolerance, so ensure your manipulator uses a precise external guide or a pivot mount to prevent rod bending.
Upgrade checklist
- ✓ Order the B05-MBL20X150S (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-MBL20X150S instead of this discontinued model.
Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X150S FAQ
Yes, the B05-MAL20X150S is discontinued. The direct replacement is the MBL20X150S. The "B05-" prefix simply marked it as a pick-and-place robot dedicated variant of the standard MAL20X150S, so the MBL shares the exact same 20 mm bore, 150 mm stroke, G1/8 port, and mounting dimensions. You will need to update your sensors, as the MBL uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M.
This double-acting cylinder operates at 0.1-1.0 MPa with a speed range of 30-800 mm/s. At 0.5 MPa it provides 157 N push and 132 N pull force; at 0.7 MPa it provides 220 N push. The maximum theoretical force is 32 kgf at 1.0 MPa. It uses a fixed rubber bumper for end-of-stroke cushioning, not an adjustable lock.
