This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement B01-MBL25X300U, 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-MAL25X300U
The AirTAC B01-MAL Special Purpose Cylinder B01-MAL25X300U 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-MBL25X300U, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X300U
The AirTAC B01-MAL25X300U 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 MAL25X300U, meaning it is mechanically identical to the standard model with a 25mm bore and 300mm stroke. Delivering 245 N of push force at 0.5 MPa, it is engineered for compact assemblies requiring a long reach. AirTAC replaced the MAL series with the MBL line, making the MBL25X300U the direct replacement, retaining the same G1/8 port, 10mm rod, and U flat-end back cover.
This legacy cylinder features a fixed rubber bumper for end-of-stroke damping and a heterogeneous two-way seal that retains grease for long service life. The original MAL body utilized threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body. Because this specific SKU lacks the -S magnet option, it cannot accommodate position sensors. For applications demanding precise end-positioning feedback, a modern MBL with CMSG or DMSG switches would be required.

Where the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X300U Is Used
PCB Conveyor Diversion
Pushes lightweight PCB routing gates along an electronics assembly line, utilizing the 300mm stroke to clear the full belt width while operating within the 245 N push limit at 0.5 MPa.
Carton Flap Folding
Extends 300mm to fold the rear flaps of small packaging cartons on a compact tape-sealing machine, taking advantage of the rigid U flat-end back cover for stable linear pushing.
Textile Yarn Guide
Traverses a yarn guide carriage across a narrow knitting head, where the 25mm bore provides sufficient 206 N pull force to tension the guide without stressing the delicate threads.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X300U with B01-MBL25X300U
To replace the B01-MAL25X300U, order the MBL25X300U. Confirm your 25mm bore, 300mm stroke, G1/8 port (PT thread form), and the U flat-end back cover. This SKU has no -S magnet, so it cannot accept a position sensor; if you need rod detection, step up to an MBL25X300S and use the current CMSG/DMSG/EMSG switch family instead of the obsolete CS1-M/DS1-M sensors. If 245 N push at 0.5 MPa is insufficient, stepping up to the 32mm bore yields 402 N push; conversely, dropping to the 20mm bore provides 157 N push. The fixed rubber bumper cannot be adjusted—if you need adjustable end-cushioning to decelerate the long 300mm stroke, look at the MBLC variant on the current line. Note that a plain MAL/MBL does not hold its load when air is lost; use an external rod lock for suspended loads. With a 300mm stroke and a 10mm rod, side-load tolerance is low, so an external guide or pivot mounting is recommended to prevent rod bending.
Upgrade checklist
- ✓ Order the B01-MBL25X300U (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-MBL25X300U instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL25X300U FAQ
Yes, the B01-MAL25X300U (an application-dedicated variant of the MAL25X300U) is discontinued. The direct replacement is the MBL25X300U, which matches the 25mm bore, 300mm stroke, 245 N push force, G1/8 port, and U flat-end cover. The modern MBL uses a riveted body instead of the older threaded covers.
At 0.5 MPa, the 25mm bore provides 245 N push and 206 N pull force; at 0.7 MPa it provides 343 N push, with a maximum theoretical force of 50 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept position sensors; legacy MAL sensors (CS1-M/DS1-M) only fit -S models, and the modern MBL uses CMSG/DMSG/EMSG switches.
