This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B05-MBL20X120S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B05-MBL20X120S 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-MAL20X120S
The AirTAC Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X120S 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 drop-in replacement is the B05-MBL20X120S, which matches its bore, stroke, force and mounting.

About the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X120S
The AirTAC B05-MAL20X120S is a discontinued compact double-acting aluminum mini round cylinder. The leading "B05-" prefix marks this as AirTAC's robot or manipulator (pick-and-place) dedicated variant, though mechanically it is identical to the base MAL20X120S. 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, so the exact drop-in replacement is the MBL20X120S, which matches the bore, stroke, force, port, and mounting.
The legacy MAL body uses threaded front and back covers, whereas the newer MBL features a riveted rolling-packed body for equally durable aluminum construction. Because this SKU includes the -S magnet, it originally paired with CS1-M or DS1-M switches; upgrading to the MBL means transitioning to the current CMSG, DMSG, or EMSG sensor families. The internal piston relies on a heterogeneous two-way seal that retains grease, and the carbon-steel rod has 20 um hard-chrome plating to resist wear during rapid robotic cycles.

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-MAL20X120S Is Used
Pick-and-Place Chassis
Drives the vertical Z-axis on a Cartesian manipulator, using its 120 mm stroke to lift small electronic components from a conveyor to a testing tray.
PCB Board Handling
Pushes raw printed circuit boards into spring-loaded edge connectors on an assembly fixture, leveraging the 157 N push force at 0.5 MPa without cracking the fiberglass.
Carton Flap Folding
Extends 120 mm to tuck inner flaps of small pharmaceutical cartons shut prior to sealing, fitting easily into the tight mechanical clearances of packaging machinery.
Replacing the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X120S with B05-MBL20X120S
To replace this discontinued cylinder, order the MBL20X120S. Confirm your 20 mm bore, 120 mm stroke, G1/8 port, and default PT thread. Because this SKU has the -S magnet, plan to swap your existing CS1-M or DS1-M sensors for CMSG, DMSG, or EMSG switches to fit the MBL body. The MAL uses a fixed rubber bumper; if your pick-and-place application now requires adjustable end-cushioning, step up to the MBLC variant on the current line.
For sizing, this 20 mm bore provides 157 N push at 0.5 MPa. If you need less force to avoid damaging delicate parts, the neighboring smaller bore is unavailable in this mini series, making 20 mm the minimum option. If the manipulator arm needs more grip force, the next size up is the 25 mm bore, which outputs 245 N push at 0.5 MPa. At 120 mm stroke, the 8 mm rod has low side-load tolerance, so ensure your robot end-effector provides an external guide or uses a pivoting knuckle to prevent rod bending. Note that a plain cylinder does not hold position when air is lost; add an external rod lock for vertical payloads.
Upgrade checklist
- ✓ Order the B05-MBL20X120S (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-MBL20X120S instead of this discontinued model.
Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X120S FAQ
Yes, the B05-MAL20X120S is discontinued. The exact drop-in replacement is the MBL20X120S, which offers the same 20 mm bore, 120 mm stroke, output force, G1/8 port, and mounting dimensions. The B05- prefix simply indicated it was a robot or manipulator dedicated variant; the MBL replacement serves this role identically.
At 0.5 MPa, it provides 157 N push and 132 N pull force. At 0.7 MPa, push increases to 220 N, with a maximum theoretical force of 32 kgf at 1.0 MPa. Because this SKU includes the -S magnet, it works with older CS1-M and DS1-M switches on the MAL body; when upgrading to the MBL, you must use CMSG, DMSG, or EMSG sensors instead.
