This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement B05-MBL20X120, 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-MAL20X120
The AirTAC B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X120 is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 120mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the B05-MBL20X120, which matches its bore, stroke, force and mounting.

About the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X120
The AirTAC B05-MAL20X120 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 base MAL20X120. It delivers 157 N of push force at 0.5 MPa and uses a G1/8 port with an 8 mm rod. AirTAC has ended this line, making the MBL20X120 the direct replacement, matching the 120 mm stroke, force, and mounting dimensions.
Because this SKU lacks the -S suffix, it has no internal magnet and cannot accept a position sensor. The original MAL body uses threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body for equally robust performance. The piston relies on a heterogeneous two-way seal that retains grease, running against a carbon-steel rod plated with 20 um hard chrome for wear resistance.

Where the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X120 Is Used
Pick-and-Place Robot Jaws
Drives the open/close motion of lightweight pneumatic grippers on SCARA robots, utilizing the 157 N push force at 0.5 MPa to secure small electronic components.
PCB Board Sorting Diverter
Extends 120 mm to push printed circuit boards from a main SMT line onto a testing spur track, fitting easily into tight 20 mm bore machinery envelopes.
Connector Pin Insertion
Provides the short, precise linear stroke needed to press IC socket pins into housings, relying on the self-lubricating front-cover bearing guide to prevent rod binding.
Replacing the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X120 with B05-MBL20X120
To replace the B05-MAL20X120, order the MBL20X120. Confirm your G1/8 port and default PT tapered thread match your fittings. Since this unit has no -S magnet, you cannot mount a sensor; if pick-and-place sequencing now requires position feedback, step up to an MBL20X120S and use the current CMSG, DMSG, or EMSG switches instead of the legacy CS1-M/DS1-M family. If you need to adjust force, stepping down is not an option as 20 mm is the smallest bore, but stepping up to the 25 mm bore yields 245 N push at 0.5 MPa. The MAL uses a fixed rubber bumper; for adjustable end-cushioning to soften rapid robot moves, look at the MBLC equivalent. Note that a plain cylinder drifts when air is lost, so add an external rod lock if gravity must be held. At 120 mm stroke, side-load risk is moderate, so ensure your manipulator jaw aligns precisely with the 8 mm rod to prevent bending.
Upgrade checklist
- ✓ Order the B05-MBL20X120 (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-MBL20X120 instead of this discontinued model.
Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X120 FAQ
Yes, the B05-MAL20X120 is discontinued. The direct replacement is the MBL20X120, which matches the 20 mm bore, 120 mm stroke, 157 N push force, G1/8 port, and mounting dimensions. The B05- prefix simply marked it as a pick-and-place robot dedicated variant, and the MBL20X120 will perform identically in your manipulator.
The full force set is: 157 N push and 132 N pull at 0.5 MPa, 220 N push at 0.7 MPa, and a maximum theoretical force of 32 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor; if you need detection, order the MBL20X120S which uses CMSG, DMSG, or EMSG switches.
