This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL25X150SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL25X150SU 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 B01-MAL Special Purpose Cylinder B01-MAL25X150SU
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL25X150SU 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 B01-MBL25X150SU, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X150SU
The AirTAC B01-MAL25X150SU is a discontinued double-acting aluminum mini round cylinder. The B01- prefix marks this as an application-dedicated (customer-specified) variant of the base MAL25X150SU, meaning it is mechanically identical to the standard model but grouped for a specific industry build. Delivering 245 N push and 206 N pull at 0.5 MPa, it features a 25 mm bore, 150 mm stroke, and a G1/8 port.
AirTAC replaced this legacy unit with the MBL25X150SU, a true drop-in replacement retaining the exact bore, stroke, output force, port size, and U flat-end rear cover. The original MAL utilizes threaded front and back covers, whereas the modern MBL features a riveted rolling-packed body. Furthermore, this SKU includes a -S magnet for position sensing; the MAL works with older CS1-M / DS1-M switches, while the MBL replacement transitions to the current CMSG / DMSG / EMSG sensor family.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL25X150SU 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 B01-MAL Special Purpose Cylinder B01-MAL25X150SU Is Used
PCB Conveyor Routing
Pushes lightweight PCB transfer gates along an electronics assembly line, utilizing the 245 N push force at 0.5 MPa to reliably overcome minor guide friction.
Carton Flap Folding
Extends 150 mm to fold small corrugated carton flaps in a packaging machine, where the compact 25 mm bore fits neatly between conveyor belts.
Textile Yarn Guide
Cycles continuously to shift a yarn guide across a weaving loom, relying on the self-lubricating front-cover bearing to maintain smooth 30-800 mm/s operation.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X150SU with B01-MBL25X150SU
To replace the B01-MAL25X150SU, order the MBL25X150SU. Confirm the 25 mm bore, 150 mm stroke, G1/8 port, and PT thread form are retained. The U flat-end back cover provides a rigid rear mount, while the built-in -S magnet requires upgrading your CS1-M / DS1-M sensors to CMSG / DMSG / EMSG switches on the new body. If you need to adjust force, step down to the 20 mm bore (157 N push at 0.5 MPa) for lighter loads, or step up to the 32 mm bore (402 N push at 0.5 MPa) for heavier resistance.
Because this 150 mm stroke exceeds the 300 mm threshold, the 10 mm piston rod is susceptible to bending under lateral stress; utilize an external guide rail or a pivot mount to manage side loads. The fixed rubber bumper softens end-of-stroke impacts but is not an adjustable cushion—choose the MBLC line if you need adjustable air cushioning. A plain cylinder does not hold position when air pressure drops; install an external rod lock for suspended loads.
Upgrade checklist
- ✓ Order the B01-MBL25X150SU (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 B01-MBL25X150SU instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL25X150SU FAQ
Yes, the B01-MAL25X150SU is discontinued. The exact drop-in replacement is the MBL25X150SU, which matches the 25 mm bore, 150 mm stroke, 245 N push force, G1/8 port, and U flat-end cover. The B01- prefix simply designated an application-specific build of the standard cylinder. You must upgrade your CS1-M / DS1-M sensors to CMSG / DMSG / EMSG switches for the new body.
At 0.5 MPa, the push force is 245 N and the pull force is 206 N. At 0.7 MPa, the push force increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa. The cylinder operates at 30-800 mm/s and uses a fixed rubber bumper, not an adjustable cushion.
