This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement B01-MBL25X300SU, 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-MAL25X300SU
The AirTAC B01-MAL Special Purpose Cylinder B01-MAL25X300SU is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 300mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the B01-MBL25X300SU, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X300SU
The AirTAC B01-MAL25X300SU 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 MAL25X300SU, 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. AirTAC replaced the entire MAL series, so the direct replacement for this SKU is the MBL25X300SU, which matches the 25 mm bore, 300 mm stroke, G1/8 port, and U flat-end back cover.
The legacy MAL body uses threaded front and back covers, whereas the newer MBL features a riveted rolling-packed body. This specific SKU includes the -S magnet for position sensing; on the MAL it pairs with older CS1-M or DS1-M switches, but the MBL replacement requires the current CMSG, DMSG, or EMSG sensor families. The piston relies on a heterogeneous two-way seal that retains grease, and the carbon-steel rod has 20 um hard-chrome plating to resist wear. End-of-stroke deceleration is handled by a fixed rubber bumper, not an adjustable cushion.

Where the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X300SU Is Used
PCB Panel Diverter
Pushes populated printed circuit boards sideways onto a secondary conveyor belt using 245 N of force at 0.5 MPa, fitting into tight machine gaps.
Carton Flap Folder
Extends 300 mm to fold the minor flaps of small packaging cartons on a continuous sealing line, relying on the U flat-end cover for rigid rear alignment.
Textile Yarn Guide
Cycles continuously to shift a yarn guide carriage across a knitting machine, using the -S magnet to confirm the 300 mm extend position.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X300SU with B01-MBL25X300SU
To replace this discontinued cylinder, order the MBL25X300SU. Confirm your 300 mm stroke, 25 mm bore, G1/8 port, and the U flat-end back cover. Because this SKU has the -S magnet, you must upgrade your position switches from the legacy CS1-M / DS1-M to the modern CMSG / DMSG / EMSG family used on the MBL. If your application requires adjustable end-cushioning to absorb kinetic energy, step up to the MBLC variant, as the MAL only offers a fixed rubber bumper.
When sizing, verify if 245 N push at 0.5 MPa is sufficient. 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. Because the 300 mm stroke is relatively long for a 10 mm rod, side-load tolerance is low; use an external guide rail or a pivot mount to prevent rod bending. Note that this cylinder will drift and cannot hold a load if air pressure is lost—the bumper softens the stroke end but does not lock the rod.
Upgrade checklist
- ✓ Order the B01-MBL25X300SU (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-MBL25X300SU instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL25X300SU FAQ
Yes, the B01-MAL25X300SU is discontinued. The direct replacement is the MBL25X300SU. The B01- prefix simply designates an application-dedicated variant of the base MAL25X300SU, so the MBL matches your 25 mm bore, 300 mm stroke, G1/8 port, and U back cover exactly. You must swap your CS1-M / DS1-M sensors for CMSG / DMSG / EMSG switches.
At 0.5 MPa it provides 245 N push and 206 N pull; at 0.7 MPa it provides 343 N push, with a theoretical maximum of 50 kgf at 1.0 MPa. It uses a fixed rubber bumper for end-of-stroke deceleration, not an adjustable air cushion. If you need adjustable cushioning, order the MBLC equivalent.
