This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement B01-MBL25X125U, 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-MAL25X125U
The AirTAC B01-MAL Special Purpose Cylinder B01-MAL25X125U is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 125mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the B01-MBL25X125U, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X125U
The AirTAC B01-MAL25X125U 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 MAL25X125U, meaning it is mechanically identical to the standard model. Delivering 245 N of push force at 0.5 MPa over a 125 mm stroke, it is engineered for tight spaces. AirTAC replaced the entire MAL line with the MBL series, making the MBL25X125U the direct upgrade. It matches the original 25 mm bore, 125 mm stroke, G1/8 port, and U flat-end back cover perfectly.
This legacy unit features a Ø10 mm carbon-steel rod with 20 um hard-chrome plating and a heterogeneous two-way seal that retains grease. The older MAL body uses threaded front and back covers, whereas the modern MBL replacement utilizes a riveted rolling-packed body. Because this specific SKU lacks an -S magnet, it cannot accept a position sensor. The cylinder relies on a fixed rubber bumper for end-of-stroke deceleration; if your application requires adjustable cushioning, you must step up to the current MBLC line.

Where the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X125U Is Used
PCB Depaneling Router
Pushes a linear cutting toolhead across a 125 mm path to singulate printed circuit boards, utilizing the 245 N push force at 0.5 MPa to maintain steady feed without stalling.
Semiconductor Test Socket
Actuates a rigid clamping plate to seal IC chips against a test bed in tight equipment bays, relying on the compact 25 mm aluminum body and U flat-end rear cover for rigid alignment.
Carton Flap Folder
Folds minor product flaps on a packaging line using a 125 mm extension stroke, where the fixed rubber bumper safely absorbs the kinetic energy at the end of every cycle.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X125U with B01-MBL25X125U
To replace the B01-MAL25X125U, order the MBL25X125U. Confirm your 125 mm stroke, G1/8 port, and the U flat-end back cover. This SKU has no -S magnet, so it cannot support a position sensor; if you need position detection on the new MBL, add the S option and note that the sensor family changes from the legacy CS1-M / DS1-M to the current CMSG / DMSG / EMSG switches. The fixed rubber bumper is not a lock; a plain MAL or MBL will drift if air pressure is lost, so use an external rod lock for suspended loads.
For sizing, this 25 mm bore yields 245 N push and 206 N pull 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). Because the 125 mm stroke is fairly long for a mini cylinder, the small Ø10 mm rod has limited side-load tolerance. Use an external guide rail or a pivot mounting accessory to prevent rod bending.
Upgrade checklist
- ✓ Order the B01-MBL25X125U (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-MBL25X125U instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL25X125U FAQ
Yes, the B01-MAL25X125U is discontinued. The direct replacement is the MBL25X125U, which matches the 25 mm bore, 125 mm stroke, G1/8 port, and U flat-end cover. The B01- prefix simply denotes an application-dedicated build of the standard MAL25X125U, so the physical specs are identical. The modern MBL uses a riveted rolling-packed body instead of the older threaded covers.
At 0.5 MPa, the push force is 245 N and the pull force is 206 N. At 0.7 MPa, the push force increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa. The operating pressure range is 0.1-1.0 MPa with a speed range of 30-800 mm/s.
