This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B05-MBL25X650S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B05-MBL25X650S 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-MAL25X650S
The AirTAC Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X650S is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 650mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B05-MBL25X650S, which matches its bore, stroke, force and mounting.

About the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X650S
The AirTAC B05-MAL25X650S is a discontinued double-acting aluminum mini round cylinder. The B05- prefix designates it as a robot and manipulator pick-and-place dedicated variant, mechanically identical to the standard MAL25X650S. It delivers 245 N push and 206 N pull at 0.5 MPa through a 25 mm bore. As the MAL line is end-of-life, the exact drop-in replacement is the MBL25X650S, matching the bore, 650 mm stroke, G1/8 port, and output force.
This unit features a built-in magnet (-S) for position detection. During the upgrade, the older threaded end covers are replaced by a riveted rolling-packed body on the MBL. Furthermore, the legacy CS1-M and DS1-M sensors used on this MAL must be swapped to the current CMSG, DMSG, or EMSG switch family on the MBL replacement. The 650 mm stroke is a non-standard made-to-order length exceeding the 500 mm standard maximum.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B05-MBL25X650S 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 | — |
| Max (@1.0 MPa) | 50 kgf | |
The B05-MBL25X650S 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-MAL25X650S Is Used
Pick-and-Place Robot Arms
Drives the vertical Z-axis stroke on automated manipulators moving electronic components across a 650 mm span, utilizing the 245 N push force to lift and place small payloads reliably.
Carton Diverting Gates
Actuates routing flaps on packaging conveyors where a long 650 mm extension is required to reach across a wide belt, relying on the 206 N pull force to retract the gate.
PCB Panel Extraction
Extends suction cup end-effectors deep into testing machinery to extract long circuit boards, depending on the -S magnet and CS1-M sensors to confirm full extension before lifting.
Replacing the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X650S with B05-MBL25X650S
To replace this discontinued cylinder, order the MBL25X650S. Confirm the G1/8 port, PT thread, and 25 mm bore. Because this SKU has the -S magnet, you must upgrade your CS1-M or DS1-M switches to the CMSG, DMSG, or EMSG family. The fixed rubber bumper carries over, but if your pick-and-place cycle needs end-cushioning, step up to the MBLC variant for adjustable air cushions.
For sizing flexibility, stepping down to the 20 mm bore yields 157 N push at 0.5 MPa, while stepping up to the 32 mm bore provides 402 N. At 650 mm, the 10 mm rod is highly susceptible to bending under lateral stress; use an external linear guide or a pivot mount. A plain cylinder drifts when air is lost, so add a pilot-operated check valve to hold manipulator loads safely.
Upgrade checklist
- ✓ Order the B05-MBL25X650S (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-MBL25X650S instead of this discontinued model.
Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X650S FAQ
Yes, the MAL series is end-of-life. The exact drop-in replacement is the MBL25X650S. It matches the 25 mm bore, 650 mm stroke, G1/8 port, and mounting dimensions. The B05- prefix simply marks this as a robot pick-and-place variant, and the MBL is fully mechanically compatible. You must upgrade your sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
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. The 650 mm stroke is a non-standard made-to-order length, exceeding the 500 mm standard maximum but remaining within the 1000 mm absolute limit for this bore.
