This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement B01-MBL25X100SU, 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-MAL25X100SU
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL25X100SU is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 100mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the B01-MBL25X100SU, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X100SU
The AirTAC B01-MAL25X100SU is a discontinued compact double-acting aluminum mini round cylinder. The B01- prefix designates this as an application-dedicated variant of the base MAL25X100SU, meaning it shares the exact same mechanical specifications—a 25 mm bore delivering 245 N push force at 0.5 MPa and a 100 mm stroke. AirTAC replaced this legacy unit with the MBL25X100SU, a direct upgrade retaining the same bore, stroke, output force, G1/8 port, and U flat-end rear cover.
Several engineering details distinguish the old and new lines. The legacy MAL body uses threaded front and back covers, whereas the modern MBL features a riveted rolling-packed body for equally robust performance. Additionally, this -S SKU includes a magnet for position sensing; the older MAL pairs with CS1-M or DS1-M switches, while the MBL replacement transitions to 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 a 20 um hard-chrome plating to resist wear.

Where the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X100SU Is Used
PCB Router Gate
Cycles a 100 mm stroke to open and close an access gate on a PCB depaneling router, using 245 N push force to ensure positive mechanical locking during operation.
Carton Flap Folder
Actuates a secondary flap-folding arm on a compact packaging line, where the U flat-end cover provides rigid mounting and the 206 N pull force retracts the arm quickly.
Lab Dispenser Tap
Drives a 100 mm pin to open a bulk reagent dispenser tap in automated diagnostic equipment, relying on the self-lubricating bearing guide for smooth, low-friction cycles.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X100SU with B01-MBL25X100SU
To replace the B01-MAL25X100SU, order the MBL25X100SU. Confirm the 25 mm bore, 100 mm stroke, PT port thread, and the U flat-end back cover. Because this SKU includes the -S magnet, you must update your sensing setup: the MAL used CS1-M or DS1-M switches, but the MBL requires CMSG, DMSG, or EMSG sensors. The cylinder uses a fixed rubber bumper, not an adjustable cushion; if your application needs end-of-stroke deceleration, step up to the MBLC variant on the current line.
For sizing, the 25 mm bore provides 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). Note that a plain double-acting cylinder does not hold its position if air pressure drops—the rod will drift. For suspended loads, add an external rod lock. At 100 mm stroke, side-load tolerance is manageable, but the 10 mm rod still requires reasonably straight alignment.
Upgrade checklist
- ✓ Order the B01-MBL25X100SU (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-MBL25X100SU instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL25X100SU FAQ
Yes, the B01-MAL25X100SU is discontinued. The direct replacement is the MBL25X100SU. The B01- prefix simply marks it as an application-dedicated variant of the base MAL25X100SU. The MBL replacement shares the exact same 25 mm bore, 100 mm stroke, G1/8 port, and U flat-end cover, but uses a modern riveted body. If you use the -S magnet, upgrade your sensors from the old CS1-M/DS1-M to the new CMSG/DMSG/EMSG series.
This double-acting cylinder operates at 0.1-1.0 MPa with a speed range of 30-800 mm/s. At 0.5 MPa it provides 245 N push and 206 N pull force. At 0.7 MPa the push force is 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa. It uses a fixed rubber bumper for end-of-stroke damping, not an adjustable air cushion.
