This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL25X400U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL25X400U 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-MAL25X400U
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL25X400U 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-MBL25X400U, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X400U
The AirTAC B01-MAL25X400U 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 MAL25X400U, meaning it is mechanically identical to the standard model. Delivering 245 N of push force at 0.5 MPa, it is replaced drop-in by the MBL25X400U. This upgrade retains the exact 25 mm bore, 400 mm stroke, G1/8 port, and flat-end U rear cover.
Mechanically, the legacy MAL relies on threaded front and back covers, whereas the modern MBL utilizes a riveted rolling-packed body for secure assembly. This specific SKU lacks a -S magnet, so it cannot support position sensing. The piston relies on a heterogeneous two-way seal to retain grease, and the carbon-steel rod features a 20 um hard-chrome plating to resist wear during continuous cycling.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL25X400U 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-MBL25X400U 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-MAL25X400U Is Used
Pouch Transfer Pusher
Pushes packaged pouches across a packaging line using 245 N of thrust, relying on the 400 mm stroke to clear a wide conveyor belt before retracting.
PCB Board Diverter
Diverts printed circuit boards from a main production lane into an inspection station, where the compact 25 mm body fits within tight machine guarding.
Carton Flap Opener
Holds open cardboard carton flaps during automated product insertion, utilizing the flat-end U rear cover for rigid mounting against the machine frame.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL25X400U with B01-MBL25X400U
To replace this discontinued cylinder, order the MBL25X400U. It matches the 25 mm bore, 400 mm stroke, PT threaded G1/8 port, and rigid U flat-end back cover. Because this SKU has no -S magnet, it cannot accept a sensor; if you require position detection, step up to an MBL25X400US and migrate to the current CMSG/DMSG/EMSG switch family (the older CS1-M/DS1-M sensors are obsolete).
When sizing, verify your force needs: the 25 mm bore yields 245 N push at 0.5 MPa. If you need less force, step down to a 20 mm bore (157 N push); for more power, step up to a 32 mm bore (402 N push). A 400 mm stroke on a 10 mm rod demands careful alignment. Use an external guide rail to prevent rod bending, as the fixed rubber bumper cannot absorb heavy side-loads. If you need adjustable end-cushioning, specify the MBLC version on the current line. Note that a plain cylinder drifts when air is lost; add an external rod lock for vertical loads.
Upgrade checklist
- ✓ Order the B01-MBL25X400U (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-MBL25X400U instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL25X400U FAQ
Yes, the B01-MAL25X400U is discontinued. The exact drop-in replacement is the MBL25X400U, which matches the 25 mm bore, 400 mm stroke, G1/8 port, and U flat-end cover. The "B01-" prefix simply marks this as an application-dedicated variant of the base MAL25X400U, so you order the standard MBL equivalent.
The 25 mm bore provides a push force of 245 N and a pull force of 206 N at 0.5 MPa. At 0.7 MPa, the push force is 343 N, with a maximum theoretical force of 50 kgf at 1.0 MPa. It uses a fixed rubber bumper, not an adjustable cushion or a lock. The cylinder will drift if air pressure is lost, so an external rod lock is required for holding suspended loads.
