This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL40X35U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL40X35U 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-MAL40X35U
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL40X35U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 35mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL40X35U, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X35U
The AirTAC B01-MAL40X35U 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 MAL40X35U, meaning it is mechanically identical to the standard line but grouped for specific customer builds. Delivering 628 N of push force and 528 N of pull force at 0.5 MPa, it is engineered for compact spaces requiring high thrust. AirTAC replaced this legacy series with the MBL40X35U, a drop-in upgrade retaining the exact 40 mm bore, 35 mm stroke, G1/4 port, and U flat-end rear cover.
Mechanically, the original MAL body utilized threaded front and back covers, whereas the current MBL replacement features a riveted rolling-packed body for structural rigidity. This SKU lacks a built-in magnet, meaning it cannot support position sensors out of the box. Internally, the piston relies on a heterogeneous two-way seal that retains grease, while the carbon-steel rod is protected by 20 um hard-chrome plating to resist wear. End-of-stroke deceleration is handled by a fixed rubber bumper, not an adjustable air cushion.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL40X35U 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-MBL40X35U 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-MAL40X35U Is Used
PCB Drilling Clamp
Secures printed circuit board panels onto drilling machine beds using 628 N of push force at 0.5 MPa, ensuring zero movement during high-speed spindle penetration.
Carton Flap Folder
Drives a short 35 mm stroke to tuck minor flaps on packaging lines, fitting into tight transfer gaps while providing 528 N of retract pull force.
Pallet Diverter Gate
Actuates a routing flap to divert heavy pallets at conveyor junctions, relying on the rigid U flat-end back cover to maintain alignment under high lateral impact.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X35U with B01-MBL40X35U
To replace the B01-MAL40X35U, order the exact MBL40X35U drop-in equivalent. It matches the 40 mm bore, 35 mm stroke, PT thread form, G1/4 port, and U flat-end back cover perfectly. Because this specific SKU lacks the -S magnet option, it cannot accept a position sensor; if your application requires end-of-stroke detection, step up to an MBL40X35US and note that the current MBL line uses modern CMSG, DMSG, or EMSG switches instead of the older CS1-M/DS1-M family.
When sizing, consider stepping down to the 32 mm bore if you need less force (it provides 402 N push at 0.5 MPa), or stepping up if the 40 mm is insufficient—though 40 mm is the largest available bore in this mini round family, delivering a maximum theoretical output of 128 kgf at 1.0 MPa. Note that a plain MAL or MBL cylinder does not hold its position when air pressure is lost; the rod will drift. For load-holding safety, install an external rod lock or a pilot-operated check valve. If end-of-stroke impact is too severe for the standard fixed rubber bumper, look to the MBLC series on the current line for an adjustable air cushion.
Upgrade checklist
- ✓ Order the B01-MBL40X35U (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-MBL40X35U instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL40X35U FAQ
Yes, the B01-MAL40X35U is discontinued. The exact drop-in replacement is the MBL40X35U, which shares the same 40 mm bore, 35 mm stroke, G1/4 port, and U flat-end cover. The "B01-" prefix simply designates an application-specific build of the standard MAL40X35U, so the MBL40X35U functions as a direct, mechanically identical substitute.
The 40 mm bore provides a push force of 628 N and a pull force of 528 N at 0.5 MPa. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa. This is the largest bore in the mini round family, and it uniquely uses a G1/4 port, whereas the 20, 25, and 32 mm bores use G1/8.
