This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement B05-MBL32X500S, 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-MAL32X500S
The AirTAC B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL32X500S is a double-acting aluminum-barrel mini round cylinder with a Ø32mm bore and 500mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the B05-MBL32X500S, which matches its bore, stroke, force and mounting.

About the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL32X500S
The AirTAC B05-MAL32X500S is a discontinued double-acting aluminum mini round cylinder engineered for manipulator and pick-and-place robot arms. The B05- prefix designates it as AirTAC's robot-dedicated variant, mechanically identical to the standard MAL32X500S. It delivers 402 N of push force at 0.5 MPa and utilizes a 12 mm carbon-steel rod with 20 um hard-chrome plating to resist wear during rapid positioning cycles. AirTAC replaced this legacy series with the MBL32X500S, a direct alternative retaining the exact bore, stroke, port, and mounting footprint.
This 32 mm bore unit features a built-in magnet (-S) for position detection. Because the MAL body uses threaded front and back covers, it differs structurally from the modern riveted rolling-packed MBL replacement. Consequently, the older CS1-M and DS1-M reed switches used on this MAL are superseded by CMSG, DMSG, or EMSG sensors on the current MBL line. The cylinder relies on a fixed rubber bumper for end-of-stroke deceleration and a heterogeneous two-way seal that retains grease for long-term lubrication.

Where the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL32X500S Is Used
Pick-and-Place Z-Axis
Drives the vertical 500 mm descent of a Cartesian manipulator gripping electronic components, utilizing the 402 N push force to overcome spring-loaded tooling release.
Pallet Divider Actuation
Extends across a packaging conveyor to reject misaligned cartons, relying on the 346 N pull force at 0.5 MPa to retract the paddle clear of the main product flow.
PCB Test Fixture Shuttle
Moves loaded printed circuit board trays into an automated optical inspection station, where the -S magnet triggers a CS1-M switch to confirm the 500 mm travel endpoint.
Replacing the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL32X500S with B05-MBL32X500S
To replace the B05-MAL32X500S, order the MBL32X500S. Verify your manipulator's fittings for the G1/8 port and M10x1.25 rod-end thread. The -S magnet on this legacy unit requires CS1-M or DS1-M switches; upgrading to the MBL means you must switch to the CMSG, DMSG, or EMSG sensor families. If your pick-and-place arm needs precise end-stop damping, note that the MAL only has a fixed rubber bumper—you should look at the current MBLC line for an adjustable air cushion. A plain cylinder does not hold its load if air pressure drops, so fit an external pilot-operated check valve for vertical manipulator safety.
At 500 mm of stroke, the 12 mm rod is highly susceptible to side-loading and bending under off-center robot payloads. Use an external linear guide or a pivot mounting accessory to absorb lateral stress. For sizing flexibility, stepping down to the 25 mm bore yields 245 N of push force at 0.5 MPa, while stepping up to the 40 mm bore provides 628 N at 0.5 MPa and upgrades the port to G1/4.
Upgrade checklist
- ✓ Order the B05-MBL32X500S (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-MBL32X500S instead of this discontinued model.
Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL32X500S FAQ
Yes, the B05-MAL32X500S is discontinued. The direct replacement is the MBL32X500S, which matches the 32 mm bore, 500 mm stroke, G1/8 port, and mounting dimensions. The B05- prefix simply indicated it was a robot and manipulator dedicated variant of the base MAL32X500S. The modern MBL uses a riveted body instead of threaded covers, and you must upgrade your position sensors from the old CS1-M / DS1-M switches to the current CMSG, DMSG, or EMSG family.
The 32 mm bore provides a push force of 402 N and a pull force of 346 N at 0.5 MPa. At 0.7 MPa, the push force increases to 563 N. The maximum theoretical force is 82 kgf when operated at the 1.0 MPa pressure limit. It operates at speeds of 30-800 mm/s.
