This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B05-MBL25X100S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B05-MBL25X100S 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-MAL25X100S
The AirTAC Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X100S is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 100mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B05-MBL25X100S, which matches its bore, stroke, force and mounting.

About the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X100S
The AirTAC B05-MAL25X100S is a discontinued compact 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 MAL25X100S. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa. AirTAC has replaced this legacy unit with the MBL25X100S, a drop-in upgrade retaining the exact 25 mm bore, 100 mm stroke, G1/8 port, and 50 kgf maximum thrust.
Transitioning to the MBL25X100S swaps the original threaded front and back covers for a riveted rolling-packed body, improving structural rigidity without altering the mounting footprint. Because this SKU includes the -S magnet, note that the older CS1-M and DS1-M reed switches used on the MAL are superseded by the current CMSG, DMSG, or EMSG solid-state sensor families on the MBL. The carbon-steel piston rod features a 20 um hard-chrome plating, guided by a self-lubricating front-cover bearing to handle rapid manipulator cycles.

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-MAL25X100S Is Used
SCARA Robot Pick-and-Place
Drives the vertical Z-axis on a SCARA robot arm for electronic PCB board handling, utilizing the 245 N push force to lift components precisely within a compact envelope.
Carton Flap Folding
Actuates a mechanical flap-folding arm on a packaging line, using the 100 mm stroke to clear the path for incoming product before returning to its home position.
Connector Insertion Press
Pushes ribbon cable connectors into PCB sockets during light assembly automation, relying on the self-lubricating bearing guide to prevent rod binding during repetitive fast cycles.
Replacing the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X100S with B05-MBL25X100S
To replace this discontinued cylinder, order the MBL25X100S. Confirm your robot arm's mounting interface and porting match the G1/8 thread and PT tapered port form. Because this unit carries the -S magnet, you must upgrade your position sensing to CMSG, DMSG, or EMSG switches, as the legacy CS1-M and DS1-M sensors do not fit the new body. The fixed rubber bumper softens end-of-stroke impacts, but if your pick-and-place cycle requires adjustable air cushioning, step up to the MBLC variant on the current line.
For sizing flexibility, stepping down to a 20 mm bore drops the 0.5 MPa push force to 157 N, while stepping up to a 32 mm bore increases it to 402 N. A plain double-acting cylinder cannot hold a vertical load if air pressure drops; the rod will drift. For vertical manipulator arms, install an external pilot-operated check valve or rod lock. At 100 mm stroke, side-load tolerance remains manageable, but the 10 mm rod still requires external guidance if subjected to lateral offsetting.
Upgrade checklist
- ✓ Order the B05-MBL25X100S (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-MBL25X100S instead of this discontinued model.
Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X100S FAQ
Yes, the B05-MAL25X100S is discontinued. The exact drop-in replacement is the MBL25X100S. The B05- prefix simply marked it as a pick-and-place robot variant; the MBL25X100S matches its 25 mm bore, 100 mm stroke, G1/8 port, and 50 kgf max force. You must swap your CS1-M or DS1-M sensors for CMSG, DMSG, or EMSG switches.
At 0.5 MPa, the push force is 245 N and the pull force is 206 N. At 0.7 MPa, the push force is 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa. It operates at speeds between 30 and 800 mm/s, with a fixed rubber bumper at each end of stroke.
