This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL40X300U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL40X300U 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-MAL40X300U
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL40X300U 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-MBL40X300U, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X300U
The AirTAC B01-MAL40X300U is a discontinued double-acting aluminum mini round cylinder. The B01- prefix designates an application-dedicated, customer-specified variant that is mechanically identical to the base MAL40X300U. Delivering 628 N of push force at 0.5 MPa, it features a 40 mm bore, a 300 mm stroke, and a G1/4 port. AirTAC replaced this legacy series with the MBL40X300U, a drop-in alternative that preserves the exact bore, stroke, output force, port size, and mounting interface.
This legacy model relies on a fixed rubber bumper for end-of-stroke damping rather than an adjustable air cushion. The original MAL body utilized threaded front and back covers, whereas the current MBL replacement features a riveted rolling-packed body. Because this specific SKU lacks an -S magnet, it cannot accommodate a position sensor. Furthermore, the 300 mm stroke combined with a 16 mm rod demands careful alignment to prevent side-load bending.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL40X300U 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-MBL40X300U 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-MAL40X300U Is Used
Packaging Conveyor Diverter
Actuates a routing flap on a high-speed packaging line, using the 628 N push force at 0.5 MPa to reliably redirect heavy cardboard cartons without stalling.
CNC Lathe Door Shuttle
Opens and closes a sliding safety enclosure on a CNC lathe, where the 300 mm stroke provides the full travel distance needed for operator access to the chuck.
Palletizer Push-Off Arm
Sweeps completed product layers onto a wooden pallet, relying on the U flat-end back cover to rigidly brace the cylinder against the heavy lateral thrust of the load.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X300U with B01-MBL40X300U
To replace the B01-MAL40X300U, order the MBL40X300U. Verify your setup requires the U flat-end back cover for rigid mounting and the default PT tapered port thread. If your machine needs adjustable end-cushioning to absorb heavy kinetic energy, step up to the MBLC40X300U on the current line. If sizing down to reduce mass, the 32 mm bore neighbor provides 402 N push at 0.5 MPa; sizing up is not possible as 40 mm is the largest MAL mini round bore.
Since the 300 mm stroke amplifies the risk of rod bending under lateral stress, utilize an external guide rail or a pivot mount to protect the 16 mm carbon-steel rod. Remember that the fixed rubber bumper softens impact but does not lock the rod; if the load must hold its place during a compressed-air loss, install an external pilot-operated check valve or rod lock.
Upgrade checklist
- ✓ Order the B01-MBL40X300U (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-MBL40X300U instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL40X300U FAQ
Yes, the B01-MAL40X300U is discontinued. The exact drop-in replacement is the MBL40X300U, which matches the 40 mm bore, 300 mm stroke, 628 N push force, and G1/4 port. The B01- prefix simply marked this as an application-dedicated variant of the base cylinder. Note that the newer MBL body uses a riveted rolling-packed construction instead of the older threaded covers.
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force is 880 N, with a maximum theoretical force of 128 kgf at 1.0 MPa. Because this SKU lacks the -S magnet code, it cannot accept a position sensor; the older MAL -S variants used CS1-M or DS1-M switches, while the MBL replacement uses CMSG, DMSG, or EMSG sensors.
