This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL25X150U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL25X150U 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-MAL25X150U
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL25X150U 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-MBL25X150U, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X150U
The AirTAC B01-MAL25X150U is a discontinued double-acting aluminum mini round cylinder. The leading "B01-" prefix designates this as an application-dedicated, customer-specified variant of the base MAL25X150U, meaning it shares the exact same 25mm bore, 150mm stroke, and mechanical specs. Delivering 245N of push force at 0.5 MPa, it is engineered for compact spaces requiring reliable linear motion. AirTAC replaced the entire MAL series with the MBL line, making the MBL25X150U the exact drop-in successor.
This legacy model features a threaded front and rear cover assembly, whereas the modern MBL utilizes a riveted rolling-packed body for structural rigidity. Because this specific SKU lacks the -S magnet option, it cannot support position sensing. Internally, a heterogeneous two-way seal retains grease around the hard-chrome plated carbon steel rod, while the U flat-end back cover provides a rigid, non-pivoting rear mount.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL25X150U 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 | — |
| Max (@1.0 MPa) | 50 kgf | |
The B01-MBL25X150U produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X150U Is Used
PCB Conveyor Routing
Actuates a routing gate on a printed circuit board conveyor, using the 245N push force at 0.5 MPa to deflect panels into testing stations without crushing delicate components.
Packaging Carton Flap Folding
Extends 150mm to fold minor flaps on small corrugated cartons in a continuous packaging line, relying on the rigid U flat-end back cover to maintain alignment during repetitive cycling.
Textile Yarn Guide
Shifts a yarn guide rail across a weaving machine to alter thread patterns, where the compact 25mm bore fits tight loom geometry and the self-lubricating bearing handles high-speed operation.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X150U with B01-MBL25X150U
To replace the B01-MAL25X150U, order the MBL25X150U. It matches the 25mm bore, 150mm stroke, G1/8 port, PT thread, and U flat-end back cover perfectly. If your application requires a position sensor, you must step up to an -S designated MBL model and use the current CMSG, DMSG, or EMSG switches, as the legacy MAL used older CS1-M or DS1-M sensors. If sizing force, stepping down to a 20mm bore yields 157N push at 0.5 MPa, while stepping up to a 32mm bore provides 402N push at 0.5 MPa. The fixed rubber bumper softens end-of-stroke impacts, but for adjustable cushioning, you must specify an MBLC on the current line. Note that a plain cylinder drifts when air is lost; use an external rod lock for suspended loads. Since the 150mm stroke exceeds 300mm, the 10mm rod has low side-load tolerance—use an external guide to prevent rod bending.
Upgrade checklist
- ✓ Order the B01-MBL25X150U (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-MBL25X150U instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL25X150U FAQ
Yes, the B01-MAL25X150U is discontinued. The exact drop-in replacement is the MBL25X150U, which shares the same 25mm bore, 150mm stroke, G1/8 port, and U flat-end mounting. The "B01-" prefix simply marked this as an application-dedicated variant of the standard MAL25X150U, so the MBL version functions identically.
At 0.5 MPa, the push force is 245N and the pull force is 206N. At 0.7 MPa, the push force is 343N, with a maximum theoretical force of 50 kgf at 1.0 MPa. Because this SKU lacks the -S magnet option, it cannot accept a position sensor; legacy MAL sensors (CS1-M/DS1-M) only function on -S models.
