This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement B05-MBL20X160S, 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-MAL20X160S
The AirTAC B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X160S is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 160mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the B05-MBL20X160S, which matches its bore, stroke, force and mounting.

About the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X160S
The AirTAC B05-MAL20X160S is a discontinued compact double-acting aluminum mini round cylinder. The B05- prefix marks it as a robot or manipulator (pick-and-place) dedicated variant, mechanically identical to the standard MAL20X160S. It delivers 157 N push and 132 N pull at 0.5 MPa. AirTAC replaced the entire MAL line with the MBL series, making the MBL20X160S your direct replacement. It matches the 20 mm bore, 160 mm stroke, 32 kgf max force, G1/8 port, and PT thread.
The legacy MAL body uses threaded front and back covers, whereas the modern MBL features a riveted rolling-packed body for equally robust performance. This specific SKU includes a built-in magnet (-S) for position detection. On the older MAL, this works with CS1-M or DS1-M reed switches; upgrading to the MBL means switching to the current CMSG, DMSG, or EMSG sensor family. The cylinder relies on a fixed rubber bumper for end-of-stroke damping and uses a heterogeneous two-way seal to retain grease.

Where the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X160S Is Used
Pick-and-Place Robot Arm
Ideal for manipulator end-effectors moving small electronic components, utilizing the 160 mm stroke to reach into tight machine trays with 157 N of push force.
PCB Board Handling
Extends to push raw printed circuit boards into testing fixtures, where the compact 20 mm bore fits neatly alongside conveyor rails without collision.
Light-Part Ejection
Retracts quickly at 30-800 mm/s to eject small plastic housings from a molding cavity, relying on the 132 N pull force to strip the part cleanly.
Replacing the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X160S with B05-MBL20X160S
To replace this manipulator cylinder, order the MBL20X160S. Confirm your 160 mm stroke, G1/8 port, and PT thread. Because this SKU has the -S magnet, you must update your position sensing: the MAL used CS1-M / DS1-M switches, but the MBL requires CMSG / DMSG / EMSG sensors. If your pick-and-place cycle needs adjustable end-cushioning to stop loads smoothly, step up to the MBLC20X160S, as the MAL only offers a fixed rubber bumper. Note that a plain cylinder drifts when air is lost; for vertical pick-and-place arms that must hold position during an outage, add an external rod lock.
For sizing flexibility, you can step down to a 16 mm bore if you need less force (though AirTAC MAL starts at 20 mm, so you would look at the smaller MBL16 series), or step up to the MAL25 / MBL25 bore which provides 245 N push at 0.5 MPa. At 160 mm stroke, the 8 mm rod is susceptible to bending if side loads occur; ensure your robot arm uses a smooth external guide or pivoting knuckle to prevent rod damage.
Upgrade checklist
- ✓ Order the B05-MBL20X160S (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-MBL20X160S instead of this discontinued model.
Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X160S FAQ
Yes, the B05-MAL20X160S is discontinued. The direct replacement is the MBL20X160S, which matches the 20 mm bore, 160 mm stroke, G1/8 port, and mounting. The B05- prefix simply designated it for robot and pick-and-place manipulator use; the replacement MBL20X160S performs the identical function.
At 0.5 MPa it provides 157 N push and 132 N pull; at 0.7 MPa it pushes 220 N, with a maximum theoretical force of 32 kgf at 1.0 MPa. Because this SKU includes a magnet (-S), it accepts position sensors. The legacy MAL uses CS1-M / DS1-M switches, but the MBL replacement requires the newer CMSG / DMSG / EMSG sensor family.
