This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL40X350U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL40X350U 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-MAL40X350U
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL40X350U is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 350mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL40X350U, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X350U
The AirTAC B01-MAL40X350U is a discontinued double-acting aluminum mini round cylinder. The B01- prefix marks this as an application-dedicated, customer-specified variant of the base MAL40X350U, meaning it shares the exact same 40mm bore, 350mm stroke, and physical specs. It delivers 628N of push force and 528N of pull force at 0.5 MPa. AirTAC replaced the MAL line with the MBL series, making the MBL40X350U the exact drop-in replacement sharing the same G1/4 port, U flat-end rear cover, and 128 kgf maximum theoretical force.
This legacy cylinder relies on a fixed rubber bumper for end-of-stroke damping rather than an adjustable air cushion. The original MAL body uses threaded front and back covers, whereas the modern MBL replacement features a riveted rolling-packed body for equally robust performance. Because this specific SKU lacks the -S magnet option, it cannot accept a position sensor. The 16mm carbon-steel rod is plated with 20 um hard chrome and guided by a self-lubricating front-cover bearing, utilizing a heterogeneous two-way seal that retains grease for long service life.

Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |

Where the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X350U Is Used
Pallet Diverter Gate
Uses the 628N push force at 0.5 MPa to reliably deflect heavy packaging pallets onto a secondary conveyor line within tight machinery footprints.
CNC Lathe Bar Feeder
Actuates a pusher carriage over the 350mm stroke to feed raw steel bar stock into the spindle, relying on the rigid U flat-end cover to maintain axial alignment.
Vertical Carton Stacker
Raises folded cardboard cartons in a packaging line, where the 128 kgf maximum theoretical force handles the cumulative weight of stacked materials.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X350U with B01-MBL40X350U
To replace the B01-MAL40X350U, order the MBL40X350U. It drops in directly with the same 40mm bore, 350mm stroke, G1/4 port, PT thread, and U flat-end back cover. If you need to adjust the bore size, stepping down to the 32mm neighbor yields 402N push at 0.5 MPa, while stepping up is not available as 40mm is the largest MAL mini round bore. Since this SKU has no -S magnet, it cannot support a sensor; if you require position detection on the new MBL, add the -S option and note that you must use the current CMSG, DMSG, or EMSG switches instead of the legacy CS1-M/DS1-M. If your application requires adjustable end-cushioning rather than the fixed rubber bumper, look to the MBLC variant on the current line.
With a 350mm stroke on a 16mm rod, side-load tolerance is low and the rod is susceptible to bending under offset loads. Use an external guide rail or a pivot mounting accessory to absorb lateral stress. Note that a plain double-acting cylinder drifts when air pressure is lost; the bumper only softens the stroke end and does not lock the load. Use an external rod lock or pilot-operated check valve if you need strict position holding.
Upgrade checklist
- ✓ Order the B01-MBL40X350U (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-MBL40X350U instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL40X350U FAQ
Yes, the B01-MAL40X350U is discontinued. The B01- prefix simply denotes an application-dedicated variant of the standard MAL40X350U. The exact drop-in replacement is the MBL40X350U, which matches the 40mm bore, 350mm stroke, G1/4 port, and U flat-end cover. The MBL upgrades the body to a riveted rolling-packed design but maintains identical output force and mounting dimensions.
At 0.5 MPa it provides 628N push and 528N pull force. At 0.7 MPa the push force is 880N, and the maximum theoretical force is 128 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet code, it cannot accept a position sensor. If you need sensing on the MBL replacement, order the -S version and use CMSG, DMSG, or EMSG switches.
