This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL25X125CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL25X125CA in place of this model. 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-MAL25X125CA
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL25X125CA 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 drop-in replacement is the B01-MBL25X125CA, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X125CA
The AirTAC B01-MAL25X125CA 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 MAL25X125CA, meaning it shares the exact same physical specifications. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa, utilizing a 10 mm carbon-steel rod with 20 um hard-chrome plating. AirTAC has replaced this legacy unit with the MBL25X125CA, a drop-in upgrade retaining the identical bore, stroke, port, and mounting interface.
This SKU features a CA pivot (clevis) back cover designed to swing on a pin, making it well-suited for arcing loads. The original MAL body uses threaded front and back covers, whereas the modern MBL replacement utilizes a riveted rolling-packed body. Because this specific configuration lacks the -S magnet option, it cannot accommodate a position sensor. The internal piston relies on a heterogeneous two-way seal that retains grease, and end-of-stroke deceleration is handled by a fixed rubber bumper rather than an adjustable air cushion.

Where the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X125CA Is Used
Pouch Packaging Diverter
Uses the CA clevis to pivot a diverter arm on a packaging line, relying on the 245 N push force at 0.5 MPa to redirect light pouches without stalling.
Textile Yarn Guide
Swings a yarn guide mechanism across a 125 mm path, where the self-lubricating front-cover bearing ensures smooth, low-friction motion for continuous textile machinery.
Carton Flap Folder
Actuates a folding linkage in a compact carton erector, using the 125 mm stroke to tuck minor flaps before tape application in tight machine footprints.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X125CA with B01-MBL25X125CA
To replace the B01-MAL25X125CA, order the MBL25X125CA. It drops directly into your existing setup with the same 25 mm bore, 125 mm stroke, G1/8 port, PT thread, and CA pivot mounting. If your application requires position sensing, you must step up to an -S magnet variant on the MBL line, which pairs with the current CMSG, DMSG, or EMSG switches rather than the older CS1-M/DS1-M sensors used on the MAL. If you need adjustable end-cushioning to soften impacts, look at the MBLC series, as the MAL only offered a fixed rubber bumper.
For sizing flexibility, stepping down to a 20 mm bore reduces the push force to 157 N at 0.5 MPa, while stepping up to a 32 mm bore increases it to 402 N. Since this 125 mm stroke exceeds 300 mm, be mindful of side-load tolerance; the 10 mm rod has limited bending resistance, so relying on the CA pivot to absorb angular misalignment or adding an external guide rail is highly recommended. Keep in mind that neither the MAL nor the MBL holds its position if air pressure is lost; the rod will drift, so add an external rod lock for suspended loads.
Upgrade checklist
- ✓ Order the B01-MBL25X125CA (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-MBL25X125CA instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL25X125CA FAQ
Yes, the B01-MAL25X125CA is discontinued. The exact drop-in replacement is the MBL25X125CA. The "B01-" prefix simply denotes an application-dedicated variant of the standard MAL25X125CA, so the MBL25X125CA matches it exactly in bore, stroke, force, G1/8 port, and CA pivot mounting. The main upgrade is that the MBL uses a riveted rolling-packed body instead of the MAL's 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 is 343 N, and the maximum theoretical force is 50 kgf at 1.0 MPa. Because this specific SKU does not include the -S magnet, it cannot accept a position sensor; if sensing is required, you need an MBL25X125CAS which uses the modern CMSG, DMSG, or EMSG switch family.
