This model is discontinued

AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement B01-MBL25X25U, 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-MAL25X25U

The AirTAC B01-MAL Special Purpose Cylinder B01-MAL25X25U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 25mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the B01-MBL25X25U, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X25U

The AirTAC B01-MAL25X25U is a discontinued compact double-acting aluminum mini round cylinder. The "B01-" prefix marks this as an application-dedicated (customer-specified) variant of the base MAL25X25U, meaning it is mechanically identical to the standard catalog model. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa. Because the MAL series is end-of-life, AirTAC replaced it with the MBL25X25U. This current-generation direct replacement matches the 25 mm bore, 25 mm stroke, G1/8 port, and U flat-end back cover exactly.

This SKU features a U flat-end back cover for rigid, straight-line mounting. It lacks the -S magnet option, so it cannot accept a position sensor. The legacy MAL body uses threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body. Both share a fixed rubber bumper and a carbon-steel rod with 20 um hard-chrome plating. If you need position feedback, the newer MBL-S uses CMSG, DMSG, or EMSG switches, while the older MAL-S used CS1-M or DS1-M sensors.

Where the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X25U Is Used

precision_manufacturing

PCB Depaneling Router Gate

Actuates a small safety gate on an electronics depaneling router, using the 245 N push force to hold the access door closed during high-speed spindle routing.

Carton Label Applicator

Extends 25 mm to tamp thermal labels onto small product cartons on a packaging line, where the short stroke and rigid U flat-end mounting ensure precise label placement.

Connector Insertion Press

Pushes wire harness connectors into PCB sockets in light electronics assembly, relying on the 206 N pull force to positively retract the rod for the next cycle.

Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X25U with B01-MBL25X25U

To replace the B01-MAL25X25U, order the MBL25X25U. It is a direct replacement retaining the 25 mm bore, 25 mm stroke, PT tapered port thread, and U flat-end cover. Because this specific SKU lacks an -S magnet, it cannot support a position sensor. If you need end-of-stroke cushioning, note that the MAL uses a fixed rubber bumper; for an adjustable air cushion, you must step up to the current-line MBLC equivalent.

When sizing, verify your force needs: this 25 mm bore yields 245 N push at 0.5 MPa. If you need less force, step down to the 20 mm bore (157 N push at 0.5 MPa). If you need more power, step up to the 32 mm bore (402 N push at 0.5 MPa). A plain double-acting cylinder does not hold its load when air pressure drops—the rod will drift. For safety against drifting, install an external rod lock or a pilot-operated check valve.

Upgrade checklist

  • ✓ Order the B01-MBL25X25U (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-MBL25X25U instead of this discontinued model.

Airtac B01-MAL Special Purpose Cylinder B01-MAL25X25U FAQ

Yes, the B01-MAL25X25U is discontinued. The direct replacement is the MBL25X25U. The "B01-" prefix simply designates an application-specific build of the standard MAL25X25U, so the MBL25X25U matches your bore, stroke, G1/8 port, and U flat-end cover perfectly. The main physical change is that the MBL uses a riveted rolling-packed body instead of the older threaded covers.

At 0.5 MPa, the 25 mm bore provides 245 N of push force and 206 N of pull force. At 0.7 MPa, the push force is 343 N, and the maximum theoretical force is 50 kgf at 1.0 MPa. Because this specific SKU does not have the -S magnet, it cannot accept a position sensor. If you order the MBL25X25US replacement with a magnet, it uses modern CMSG, DMSG, or EMSG switches rather than the legacy CS1-M or DS1-M sensors.
