This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement B01-MBL25X75U, 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-MAL25X75U
The AirTAC B01-MAL Special Purpose Cylinder B01-MAL25X75U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 75mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the B01-MBL25X75U, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X75U
The AirTAC B01-MAL25X75U is a discontinued double-acting aluminum mini round cylinder. The B01- prefix marks this as an application-dedicated (customer-specified) variant, mechanically identical to the standard MAL25X75U. Delivering 245 N push and 206 N pull at 0.5 MPa, it is replaced by the MBL25X75U. The MBL is a direct replacement retaining the 25 mm bore, 75 mm stroke, G1/8 port, and U flat-end back cover.
This legacy series uses threaded front and back covers, whereas the current MBL features a riveted rolling-packed body. Because this specific SKU lacks the -S magnet option, it cannot support position sensing. The internal piston relies on a heterogeneous two-way seal that retains grease, running on a hard-chrome plated carbon-steel rod.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL25X75U 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 | — |

Where the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X75U Is Used
PCB Depaneling Router
Pushes a 75 mm pin to separate routed circuit boards, using the 245 N force at 0.5 MPa to cleanly break connection tabs without stressing the substrate.
Carton Flap Folder
Folds minor flaps on small packaging boxes in tight machinery spaces, relying on the rigid U flat-end back cover to maintain alignment during the 75 mm stroke.
Lab Tube Ejector
Extends 75 mm to eject filled test tubes from a centrifuge carousel, using the 206 N pull force to positively retract the rod against the rubber bumper.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X75U with B01-MBL25X75U
To replace the B01-MAL25X75U, order the MBL25X75U. Verify your 75 mm stroke, G1/8 port, and U flat-end back cover. Since this SKU has no -S magnet, it cannot accept a sensor; if you need position detection, step up to an MBL25X75S and use the current CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. The MAL uses a fixed rubber bumper, so if your application requires adjustable end-cushioning, you must switch to the MBLC line.
For sizing, if 206 N pull at 0.5 MPa is insufficient, step up to the 32 mm bore (402 N push). If you need a lighter footprint, step down to the 20 mm bore (157 N push). A plain cylinder drifts when air is lost, so use an external rod lock for vertical loads. At 75 mm stroke, side-load risk is low, but the 10 mm rod still requires reasonably linear motion.
Upgrade checklist
- ✓ Order the B01-MBL25X75U (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-MBL25X75U instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL25X75U FAQ
Yes, the B01-MAL25X75U is discontinued. The direct replacement is the MBL25X75U, which matches the 25 mm bore, 75 mm stroke, G1/8 port, and U flat-end cover. The B01- prefix simply denotes an application-dedicated build of the standard MAL cylinder.
At 0.5 MPa it provides 245 N push and 206 N pull; at 0.7 MPa it provides 343 N push, with a maximum theoretical force of 50 kgf at 1.0 MPa. Because this SKU lacks the -S magnet, it cannot accept a position sensor.
