This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement B01-MBL25X250SCA, 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 B01-MAL Special Purpose Cylinder B01-MAL25X250SCA
The AirTAC B01-MAL Special Purpose Cylinder B01-MAL25X250SCA is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 250mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the B01-MBL25X250SCA, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X250SCA
The AirTAC B01-MAL25X250SCA is a discontinued double-acting aluminum mini round cylinder. The leading "B01-" prefix marks this as an application-dedicated (customer-specified) variant of the base MAL25X250SCA, meaning it is mechanically identical to the standard catalog model. Delivering 245 N of push force at 0.5 MPa over a 250 mm stroke, it is now replaced by the MBL25X250SCA.
This legacy MAL unit features threaded front and back covers, whereas the current MBL replacement uses a riveted rolling-packed body. The -S magnet on this SKU pairs with older CS1-M / DS1-M switches, but upgrading to the MBL requires switching to CMSG / DMSG / EMSG sensors. A heterogeneous two-way seal retains grease for a long service life, and the carbon-steel rod has a 20 um hard-chrome plating to resist wear.

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-MAL25X250SCA Is Used
Textile Loom Tensioning
Drives a 250 mm travel guide arm on a weaving machine, using the 245 N push force to maintain consistent yarn tension during high-speed operation.
Package Sorting Diverter
Extends a routing flap on a logistics conveyor, where the CA pivot back cover accommodates the slight arcing motion needed to push parcels off the main belt.
Carton Flap Folder
Actuates a 250 mm folding mechanism on a packaging line, relying on the compact 25 mm bore to fit within tight machine guarding while handling light cardboard.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X250SCA with B01-MBL25X250SCA
To replace this discontinued cylinder, order the MBL25X250SCA direct equivalent. It matches the 25 mm bore, 250 mm stroke, G1/8 port, PT thread, CA pivot back cover, and -S magnet exactly. If you need to step down, the 20 mm bore offers 157 N push at 0.5 MPa; if you need more force, stepping up to the 32 mm bore yields 402 N. Remember that the fixed rubber bumper only softens end-of-stroke impacts and does not lock the rod. If air pressure drops, the load will drift unless you add an external rod lock or pilot-operated check valve.
Because the 250 mm stroke is 300 mm or less, side-load risk is moderate, but the 10 mm rod still has low bending tolerance. The CA pivot back cover helps by allowing the cylinder to swing on a pin, absorbing arcing loads. If you require adjustable end-cushioning instead of the fixed rubber bumper, look at the current MBLC line.
Upgrade checklist
- ✓ Order the B01-MBL25X250SCA (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-MBL25X250SCA instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL25X250SCA FAQ
Yes, the B01-MAL25X250SCA is discontinued. The direct replacement is the MBL25X250SCA, which shares the exact same 25 mm bore, 250 mm stroke, G1/8 port, CA pivot back cover, and -S magnet. The "B01-" prefix simply designated it as an application-specific build of the standard MAL model. When upgrading, note that the older CS1-M / DS1-M sensors must be replaced with CMSG / DMSG / 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 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.
