This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL25X400CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL25X400CA 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-MAL25X400CA
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL25X400CA is a double-acting aluminum-barrel mini round cylinder with a Ø25mm bore and 400mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL25X400CA, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X400CA
The AirTAC B01-MAL25X400CA 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 MAL25X400CA, meaning it is mechanically identical to the standard catalog model. Delivering 245 N of push force at 0.5 MPa over a 400 mm stroke, it has been superseded by the MBL25X400CA. This current-line drop-in replacement matches the exact bore, port, and CA pivot mounting.
Unlike the threaded front and back covers found on this legacy MAL body, the MBL upgrade utilizes a riveted rolling-packed construction for the same internal ratings. Because this specific SKU lacks the -S magnet code, it cannot accept a position sensor. The bore relies on a heterogeneous two-way seal that retains grease, paired with a self-lubricating front-cover bearing guide to support the Ø10 mm carbon-steel rod.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL25X400CA 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 | — |
| Max (@1.0 MPa) | 50 kgf | |
The B01-MBL25X400CA produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X400CA Is Used
Textile Loom Tensioning
Uses the 245 N push force at 0.5 MPa to maintain yarn tension across a 400 mm carriage travel, relying on the CA pivot to absorb frame oscillation.
Parcel Sorter Diverter
Actuates a routing flap over 400 mm to push small totes between belts, where the compact 25 mm bore fits within tight conveyor side-rail gaps.
Palletizing Pin Stop
Extends 400 mm to block incoming cardboard cartons at a winding station, using the fixed rubber bumper to soften the impact of the stroke endpoint.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X400CA with B01-MBL25X400CA
To replace the B01-MAL25X400CA, order the MBL25X400CA. It provides drop-in compatibility by preserving the 25 mm bore, 400 mm stroke, G1/8 port, PT thread form, and CA pivot back cover. If your mechanism requires end-of-stroke cushioning beyond the fixed rubber bumper found on this MAL, you must step up to the MBLC series for adjustable air cushions. If sizing force, stepping down to the 20 mm bore yields 157 N push at 0.5 MPa, while stepping up to the 32 mm bore provides 402 N push at 0.5 MPa. Note that a plain cylinder drifts when air is lost; add an external rod lock for vertical or gravity-loaded holds.
At 400 mm of travel, the 10 mm rod is highly susceptible to bending under lateral stress. The CA clevis back cover is essential here, allowing the body to swing on a pin and absorb arcing alignment shifts. For rigid mounts over this long stroke, an external guide rail is strongly recommended to prevent seal damage.
Upgrade checklist
- ✓ Order the B01-MBL25X400CA (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-MBL25X400CA instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL25X400CA FAQ
Yes, the B01-MAL25X400CA is discontinued. The exact drop-in replacement is the MBL25X400CA, which matches the 25 mm bore, 400 mm stroke, G1/8 port, and CA pivot back cover. The B01- prefix simply denotes an application-dedicated variant of the base MAL cylinder, so the MBL model fits identically.
At 0.5 MPa it provides 245 N push and 206 N pull force, increasing to 343 N push at 0.7 MPa, with a maximum theoretical force of 50 kgf at 1.0 MPa. Because this SKU lacks the -S magnet code, it cannot accept a position sensor; if sensing is needed, order an MBL with -S (which uses the newer CMSG/DMSG/EMSG switches instead of the legacy CS1-M/DS1-M).
