This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement B01-MBL25X75SU, 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-MAL25X75SU
The AirTAC B01-MAL Special Purpose Cylinder B01-MAL25X75SU 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-MBL25X75SU, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X75SU
The AirTAC B01-MAL25X75SU is a discontinued double-acting aluminum mini round cylinder. The leading "B01-" prefix marks this as an application-dedicated, customer-specified variant of the base MAL25X75SU; mechanically, it delivers the exact same performance, delivering 245 N of push force at 0.5 MPa. AirTAC replaced this legacy series with the MBL25X75SU, a direct upgrade retaining the 25 mm bore, 75 mm stroke, G1/8 port, and U flat-end rear cover.
This unit features a built-in magnet (-S) for position sensing and a fixed rubber bumper. Two structural facts distinguish the old from the new: the MAL relies on threaded front and back covers, whereas the MBL utilizes a riveted rolling-packed body. Additionally, the -S magnet on this legacy cylinder pairs with older CS1-M or DS1-M reed switches, while the MBL replacement transitions to the current CMSG, DMSG, or EMSG sensor families.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL25X75SU 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-MAL25X75SU Is Used
PCB Depaneling Router
Actuates the cutting tool guide arm in a compact PCB router, using its 245 N push force at 0.5 MPa to maintain steady lateral pressure during board separation.
Carton Flap Folder
Folds minor product flaps on a packaging conveyor in tight clearances, utilizing the 75 mm stroke and U flat-end cover for rigid, straight-line extension.
Lab Tube Capper
Drives the rotary capping head down onto blood collection tubes, where the self-lubricating front-cover bearing guide ensures smooth rod travel without external grease.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X75SU with B01-MBL25X75SU
To replace this discontinued cylinder, order the MBL25X75SU. Verify your 25 mm bore, 75 mm stroke, PT thread, and the U flat-end back cover. Because this SKU includes the -S magnet, plan to upgrade your sensing setup: the legacy CS1-M and DS1-M switches are superseded by CMSG, DMSG, or EMSG sensors on the MBL line. If your application requires adjustable cushioning rather than the fixed rubber bumper found here, step up to the MBLC variant on the current line.
For sizing flexibility, stepping down to the 20 mm bore drops the 0.5 MPa push force to 157 N, while stepping up to the 32 mm bore increases it to 402 N. Keep in mind that a plain double-acting cylinder drifts when air pressure is lost—the bumper softens end-of-stroke impacts but does not lock the rod. For suspended loads, install an external pilot-operated check valve or rod lock.
Upgrade checklist
- ✓ Order the B01-MBL25X75SU (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-MBL25X75SU instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL25X75SU FAQ
Yes, the B01-MAL25X75SU is discontinued. The direct replacement is the MBL25X75SU, 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 variant, so the MBL functions as a direct mechanical replacement.
At 0.5 MPa, the push force is 245 N and the pull force is 206 N. At 0.7 MPa, the push force is 343 N, with a maximum theoretical force of 50 kgf at 1.0 MPa. Because this SKU has the -S magnet, it works with older CS1-M and DS1-M switches; when you upgrade to the MBL, you must switch to CMSG, DMSG, or EMSG sensors.
