This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL40X300SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL40X300SU 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-MAL40X300SU
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL40X300SU is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 300mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL40X300SU, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X300SU
The AirTAC B01-MAL40X300SU 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 MAL40X300SU, meaning it is mechanically identical to the standard catalog model. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa, utilizing a 16 mm carbon-steel rod with 20 um hard-chrome plating. AirTAC replaced the MAL family with the MBL line, making the MBL40X300SU the exact drop-in replacement, matching the 40 mm bore, 300 mm stroke, G1/4 port, and U flat-end rear cover.
This legacy model features a threaded front and back cover assembly, whereas the current MBL utilizes a riveted rolling-packed body. The built-in -S magnet on this unit functions with the older CS1-M and DS1-M reed switches; upgrading to the MBL requires switching to the current CMSG, DMSG, or EMSG sensor families. The cylinder relies on a fixed rubber bumper for end-of-stroke damping and uses a heterogeneous two-way seal that retains grease for consistent cycling.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL40X300SU carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The B01-MBL40X300SU 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-MAL40X300SU Is Used
Pallet Diverting Gate
Drives a 300 mm routing flap on a packaging conveyor, using the 628 N push force at 0.5 MPa to deflect heavy cardboard cartons onto a secondary belt.
CNC Lathe Bar Pusher
Feeds raw steel stock through a spindle guide tube, relying on the U flat-end cover for rigid alignment and the -S magnet to confirm stock insertion.
Warehouse Vertical Lifter
Raises tote bins 300 mm between roller conveyors, requiring an external guide rail to support the load since the 16 mm rod cannot tolerate side-load bending.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X300SU with B01-MBL40X300SU
To replace the B01-MAL40X300SU, order the MBL40X300SU, ensuring you match the existing PT port threads, U flat-end back cover, and -S magnet. Because the -S magnet switches sensor families from CS1-M/DS1-M to CMSG/DMSG/EMSG on the new MBL, you must update your proximity switches during the swap. If you need adjustable air cushioning at the stroke ends—which neither this MAL nor the standard MBL offers—step up to the MBLC variant. For sizing flexibility, stepping down to a 32 mm bore drops the 0.5 MPa push force to 402 N, while no larger mini round bore exists in this family. Note that a plain double-acting cylinder drifts when air pressure is lost; if the 300 mm stroke carries a vertical load, install an external rod lock or pilot-operated check valve. Furthermore, the 300 mm stroke on a 16 mm rod creates a bending risk under side loads—use an external guide rail or a pivot mounting bracket to prevent rod damage.
Upgrade checklist
- ✓ Order the B01-MBL40X300SU (same bore/stroke/force)
- ✓ Same G1/4 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-MBL40X300SU instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL40X300SU FAQ
Yes, the B01-MAL40X300SU is discontinued. The exact drop-in replacement is the MBL40X300SU, which matches the 40 mm bore, 300 mm stroke, G1/4 port, and U flat-end mounting. The "B01-" prefix simply marked this as an application-dedicated variant; the MBL replacement fits the exact same space. Note that the MBL uses a riveted body instead of threaded covers, and the -S magnet requires upgrading from the old CS1-M/DS1-M switches to the CMSG/DMSG/EMSG families.
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa. The operating speed ranges from 30-800 mm/s, and it uses a fixed rubber bumper rather than an adjustable cushion.
