This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement B05-MBL25X400S, 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-MAL25X400S
The AirTAC B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X400S is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 400mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the B05-MBL25X400S, which matches its bore, stroke, force and mounting.

About the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X400S
The AirTAC B05-MAL25X400S 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 MAL25X400S. It delivers 245 N push and 206 N pull at 0.5 MPa, utilizing a 10 mm carbon-steel rod with 20 um hard chrome plating to resist wear during rapid automated cycles.
AirTAC replaced this legacy unit with the MBL25X400S, a direct upgrade retaining the exact 25 mm bore, 400 mm stroke, G1/8 port, and 50 kgf maximum force. The obsolete MAL features threaded front and back covers, whereas the current MBL utilizes a riveted rolling-packed body. Furthermore, this SKU includes a magnet (-S) for position detection; the original MAL pairs with older CS1-M or DS1-M switches, while the MBL successor transitions to the modern CMSG, DMSG, or EMSG sensor families.

Where the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X400S Is Used
Pick-and-Place Robot Arms
Drives the 400 mm vertical Z-axis stroke on cartesian manipulators, providing 245 N of push force at 0.5 MPa to lift and position lightweight electronic components.
PCB Board Sorting
Actuates a 400 mm transfer arm across a conveyor belt to route printed circuit boards into testing fixtures, relying on the self-lubricating bearing guide for smooth horizontal movement.
Packaging Lane Diversion
Extends 400 mm to push small cardboard cartons from a main production line into secondary packing lanes, utilizing the fixed rubber bumper to soften the rapid impact at full extension.
Replacing the Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X400S with B05-MBL25X400S
To replace the B05-MAL25X400S, order the MBL25X400S. Confirm your 400 mm stroke, G1/8 port, and PT thread form. Because this SKU includes the -S magnet, you must upgrade your sensing components: the legacy CS1-M and DS1-M switches are incompatible with the MBL body, requiring a switch to CMSG, DMSG, or EMSG sensors. The MAL relies on a fixed rubber bumper for end-of-stroke deceleration; if your pick-and-place application requires adjustable cushioning to prevent shock, step up to the MBLC variant on the current line.
When sizing, verify if 245 N push at 0.5 MPa is sufficient for your payload. Stepping down to a 20 mm bore drops the push force to 157 N, while stepping up to a 32 mm bore increases it to 402 N. At 400 mm of travel, the 10 mm rod is highly susceptible to bending under lateral stress; utilize a CA or SDB pivot mount to absorb arcing loads, or install an external linear guide. Note that a plain cylinder drifts when air pressure is lost, so deploy an external rod lock for vertical payload holding.
Upgrade checklist
- ✓ Order the B05-MBL25X400S (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-MBL25X400S instead of this discontinued model.
Airtac B05-MAL Robot-Dedicated Pneumatic Cylinder B05-MAL25X400S FAQ
Yes, the B05-MAL25X400S is discontinued. The direct replacement is the MBL25X400S, which matches the 25 mm bore, 400 mm stroke, G1/8 port, and 50 kgf maximum force. The B05- prefix simply indicated it was a manipulator-dedicated variant; the MBL replacement handles the exact same pick-and-place applications.
At 0.5 MPa it provides 245 N push and 206 N pull; at 0.7 MPa it provides 343 N push, with a maximum theoretical force of 50 kgf at 1.0 MPa. Because this SKU includes the -S magnet, it originally used CS1-M or DS1-M switches; when upgrading to the MBL replacement, you must switch to CMSG, DMSG, or EMSG sensors.
