This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement B05-MBL20X100, 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-MAL20X100
The AirTAC Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X100 is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 100mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the B05-MBL20X100, which matches its bore, stroke, force and mounting.

About the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X100
The AirTAC B05-MAL20X100 is a discontinued compact double-acting aluminum mini round cylinder. The leading "B05-" prefix marks this as a robot or manipulator pick-and-place dedicated variant, though it is mechanically identical to the base MAL20X100. It delivers 157 N of push force at 0.5 MPa and operates with an 8 mm carbon-steel rod hard-chrome plated to 20 um. AirTAC replaced this legacy unit with the MBL20X100, a direct alternative retaining the exact 20 mm bore, 100 mm stroke, G1/8 port and mounting footprint.
Buyers should note two engineering details. First, the original MAL uses threaded front and back covers, whereas the MBL replacement features a riveted rolling-packed body for structural rigidity. Second, this specific SKU lacks a magnet (-S), so it cannot accept position sensors like the CS1-M or DS1-M. The cylinder relies on a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable air cushion.

Where the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X100 Is Used
Pick-and-Place Robot Arms
Drives the vertical Z-axis on Cartesian manipulators moving small electronic components, utilizing the 157 N push force at 0.5 MPa for reliable placement.
PCB Sorting Gates
Actuates lightweight diverter flaps on conveyor lines to route printed circuit boards, taking advantage of the compact 20 mm aluminum body in tight machinery.
Tray Indexing Pushers
Advances thin plastic packaging trays one position at a time using the 100 mm stroke, relying on the self-lubricating front-cover bearing for smooth repetitive motion.
Replacing the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X100 with B05-MBL20X100
To replace the B05-MAL20X100, order the MBL20X100. Confirm your 100 mm stroke, G1/8 port, and PT thread form. Because this SKU has no -S suffix, it cannot support a sensor; if your pick-and-place manipulator requires position feedback, step up to an MBL20X100S and use the current CMSG or DMSG switches instead of the legacy CS1-M. The fixed rubber bumper is adequate for light loads, but if your robotic arm cycles rapidly and needs end-cushioning, look at the MBLC20X100 which adds an adjustable air cushion.
For sizing flexibility, you can step down to a 12 mm bore if you need less force, or step up to the 25 mm bore (MBL25X100) which provides 245 N push at 0.5 MPa. A plain MBL does not hold its position when air pressure drops; the rod will drift. If gravity or shock loads affect your manipulator, install an external rod lock. At 100 mm stroke the side-load risk is moderate, but the small 8 mm rod still requires careful alignment to prevent premature seal wear.
Upgrade checklist
- ✓ Order the B05-MBL20X100 (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-MBL20X100 instead of this discontinued model.
Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X100 FAQ
Yes, the B05-MAL20X100 is discontinued. The direct replacement is the MBL20X100. It matches the 20 mm bore, 100 mm stroke, G1/8 port, and 8 mm rod. The B05- prefix simply indicated it was dedicated to robot and manipulator pick-and-place applications, and the MBL replacement fulfills the exact same mechanical function.
At 0.5 MPa it provides 157 N push and 132 N pull force. At 0.7 MPa the push force is 220 N, with a maximum theoretical force of 32 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 MBL20X100S which uses CMSG or DMSG switches.
