This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL40X100SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL40X100SU 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-MAL40X100SU
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL40X100SU is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 100mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL40X100SU, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X100SU
The AirTAC B01-MAL40X100SU is a discontinued, double-acting aluminum mini round cylinder. The B01- prefix marks this as an application-dedicated, customer-specified variant of the standard MAL40X100SU, meaning it shares the exact same 40mm bore, 100mm stroke, G1/4 port, and physical specs while being grouped for a specific industrial use case. Delivering 628N of push force at 0.5MPa, it handles heavier small-part actuation. AirTAC replaced the MAL series with the MBL line, making the MBL40X100SU the exact drop-in replacement.
Mechanically, this legacy unit relies on a threaded front and back cover assembly, whereas the modern MBL utilizes a riveted rolling-packed body for structural rigidity. Because this SKU includes the -S magnet, it was designed to work with the older CS1-M and DS1-M reed switches; upgrading to the MBL means transitioning to the current CMSG, DMSG, or EMSG sensor families. The cylinder uses a fixed rubber bumper for end-of-stroke deceleration and a heterogeneous two-way seal that retains grease for long-term friction reduction.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL40X100SU 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-MBL40X100SU 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-MAL40X100SU Is Used
Pallet Diverting Gate
Provides the 628N push force at 0.5MPa needed to snap a heavy conveyor diverting gate into place, using the 100mm stroke to clear the passing pallet footprint.
Corrugated Box Flap Folder
Drives a rigid folding arm to tuck heavy corrugated cardboard flaps during case erecting, relying on the U flat-end cover to hold alignment under sudden impact.
Stamping Press Ejector
Kicks small aluminum stamped parts out of a die cavity using the 16mm hard-chrome plated carbon steel rod, where the -S magnet tracks ejection completion via a CS1-M sensor.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X100SU with B01-MBL40X100SU
To replace the B01-MAL40X100SU, order the MBL40X100SU, which matches the 40mm bore, 100mm stroke, 628N push force at 0.5MPa, G1/4 port, and U flat-end back cover. Confirm your port thread form is PT (tapered). If your application requires adjustable air cushioning instead of the fixed rubber bumper, step up to the MBLC40X100SU on the current line. If sizing this bore for a new build, stepping down to the 32mm bore yields 402N push at 0.5MPa, while no larger bore exists in this mini series. Note that a plain MAL or MBL does not hold its position when air is lost; the rod will drift, so add an external rod lock for vertical loads. Furthermore, if a cushion is needed, the fixed rubber bumper is not a lock.
Upgrade checklist
- ✓ Order the B01-MBL40X100SU (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-MBL40X100SU instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL40X100SU FAQ
Yes, the B01-MAL40X100SU is discontinued. The B01- prefix simply denotes an application-dedicated variant of the base cylinder. The exact drop-in replacement is the MBL40X100SU, which matches the 40mm bore, 100mm stroke, G1/4 port, and U flat-end cover. The MBL uses a riveted rolling-packed body instead of threaded covers, and if you use the -S magnet, you must switch from the older CS1-M/DS1-M switches to the current CMSG/DMSG/EMSG sensors.
At 0.5MPa it provides 628N push and 528N pull force. At 0.7MPa the push force is 880N, with a maximum theoretical force of 128kgf at 1.0MPa. It features a 16mm carbon-steel rod with 20um hard-chrome plating, an M12x1.25 rod-end thread, and operates at speeds of 30-800mm/s.
