This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B05-MBL25X150S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B05-MBL25X150S 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-MAL25X150S
The AirTAC Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X150S is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 150mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B05-MBL25X150S, which matches its bore, stroke, force and mounting.

About the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X150S
The AirTAC B05-MAL25X150S is a discontinued compact double-acting aluminum mini round cylinder. The leading "B05-" prefix designates this as a robot and manipulator (pick-and-place) dedicated variant, though it is mechanically identical to the standard MAL25X150S. Delivering 245 N of push force at 0.5 MPa over a 150 mm stroke, it has been replaced by the drop-in MBL25X150S, which matches the bore, stroke, output force, G1/8 port, and mounting dimensions exactly.
This legacy model features a Ø10 mm carbon-steel rod with 20 um hard-chrome plating and a self-lubricating front-cover bearing guide. The original MAL body used threaded front and back covers, whereas the current MBL replacement utilizes a riveted rolling-packed body. Because this SKU includes the -S magnet, it originally paired with CS1-M / DS1-M switches; upgrading to the MBL25X150S requires switching to the current CMSG / DMSG / EMSG sensor family.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B05-MBL25X150S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | — |

Where the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X150S Is Used
Pick-and-Place Robot Arms
Drives the vertical Z-axis on manipulators transferring electronic components, using its 245 N push force at 0.5 MPa to lift and place small assemblies quickly.
PCB Board Sorting
Actuates a 150 mm stroke to push printed circuit boards from an inspection conveyor into packaging trays within tight machine cells.
Small Part Ejection
Extends 150 mm to eject plastic molded parts from a stationary fixture, relying on the self-lubricating front-cover bearing for millions of friction-free cycles.
Replacing the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X150S with B05-MBL25X150S
To replace the B05-MAL25X150S, order the MBL25X150S. Confirm your G1/8 port, PT thread form, and 150 mm stroke. The -S magnet means you must upgrade your CS1-M or DS1-M switches to the CMSG, DMSG, or EMSG family. If your application requires an adjustable air cushion rather than the fixed rubber bumper found on this MAL, step up to the MBLC25X150S. If sizing force, stepping down to a 20 mm bore yields 157 N push at 0.5 MPa, while stepping up to a 32 mm bore provides 402 N push at 0.5 MPa. Note that a plain MAL/MBL does not hold its load when air is lost; add an external rod lock for vertical pick-and-place safety. At 150 mm stroke, the 10 mm rod has low side-load tolerance, so ensure your manipulator provides a rigid guide or use a pivot mount to prevent rod bending.
Upgrade checklist
- ✓ Order the B05-MBL25X150S (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-MBL25X150S instead of this discontinued model.
Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X150S FAQ
Yes, the B05-MAL25X150S (a manipulator-dedicated variant of the MAL25X150S) is discontinued. The exact drop-in replacement is the MBL25X150S, which offers the same 25 mm bore, 150 mm stroke, 245 N push force, G1/8 port, and mounting footprint. The B05- prefix only indicated the robot application; mechanically it is identical to the base MAL cylinder.
The 25 mm bore provides 245 N push and 206 N pull at 0.5 MPa, 343 N push at 0.7 MPa, and a maximum theoretical force of 50 kgf at 1.0 MPa. Because this SKU includes the -S magnet, it originally used CS1-M / DS1-M switches. The MBL25X150S replacement requires the newer CMSG / DMSG / EMSG sensor family.
