This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B05-MBL20X125S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B05-MBL20X125S 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-MAL20X125S
The AirTAC Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X125S is a double-acting aluminum-barrel mini round cylinder with a Ø20mm bore and 125mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B05-MBL20X125S, which matches its bore, stroke, force and mounting.

About the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X125S
The AirTAC B05-MAL20X125S is a discontinued double-acting aluminum mini round cylinder. The B05- prefix marks it as a robot and manipulator (pick-and-place) dedicated variant, mechanically identical to the standard MAL20X125S. It delivers 157 N push and 132 N pull at 0.5 MPa, featuring a G1/8 port and an 8 mm rod. AirTAC replaced this legacy series with the MBL20X125S, a drop-in alternative retaining the exact bore, stroke, force, port and mounting.
This unit includes a built-in magnet (-S) for position detection. Upgrading to the MBL changes the body from threaded covers to a riveted rolling-packed design, and the sensor family shifts from the older CS1-M / DS1-M to the current CMSG / DMSG / EMSG switches. The 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 manipulator cycles.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B05-MBL20X125S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | — |
| Max (@1.0 MPa) | 32 kgf | |
The B05-MBL20X125S produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X125S Is Used
Pick-and-Place Chucks
Drives the linear extend/retract motion on small manipulator arms moving electronic components, utilizing the 157 N push force to actuate gripper chucks reliably.
PCB Board Handling
Positions vacuum suction nozzles in automated test handlers, where the 125 mm stroke provides the exact vertical travel needed to clear conveyor guides.
Tray Sorting Diverters
Actuates lightweight pneumatic flappers in packaging lines to sort small plastic trays, benefiting from the compact 20 mm aluminum body in dense routing cells.
Replacing the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X125S with B05-MBL20X125S
To replace the B05-MAL20X125S, order the MBL20X125S. Confirm the 20 mm bore, 125 mm stroke, G1/8 port, and PT thread are retained. Because this SKU has the -S magnet, you must update your position sensors to the MBL-compatible CMSG / DMSG / EMSG family. If your application needs adjustable end-cushioning to soften impacts, step up to the MBLC variant, as the MAL only offers a fixed rubber bumper. For position holding on a vertical manipulator arm, note that a plain cylinder drifts when air is lost; install an external rod lock.
For sizing flexibility, stepping down to a 16 mm bore (if available from other lines) lowers your force, while stepping up to the 25 mm MAL/MBL bore increases push force to 245 N at 0.5 MPa. At 125 mm stroke, the 8 mm rod is vulnerable to side-load bending; use a CA pivot or external guide to protect the rod seal.
Upgrade checklist
- ✓ Order the B05-MBL20X125S (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-MBL20X125S instead of this discontinued model.
Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL20X125S FAQ
Yes, the B05-MAL20X125S is discontinued. The exact drop-in replacement is the MBL20X125S, which matches the 20 mm bore, 125 mm stroke, G1/8 port, and 8 mm rod. The B05- prefix simply designated it for robot and manipulator use; the MBL replacement fits those same pick-and-place applications.
At 0.5 MPa it provides 157 N push and 132 N pull; at 0.7 MPa push is 220 N, with a maximum theoretical force of 32 kgf at 1.0 MPa. The -S suffix means it has a magnet for CS1-M / DS1-M switches. When you switch to the MBL replacement, you must upgrade to CMSG / DMSG / EMSG sensors.
